Thermochemical studies of metal organic frameworks
Alexandra Navrotsky
Peter A. Rock Thermochemistry Laboratory, University of California Davis
Abstract
The thermodynamic stability of new hybrid organic-inorganic materials, including
metal organic frameworks (MOF) and hybrid perovskites for solar applications must be
known to assess their long-term behavior in use. Recent acid solution calorimetric
studies in our laboratory have emphasized MOF polymorphs and hybrid halide
perovskites. A series of MOF polymorphs prepared by grinding confirms that the
energetics depend on the molar volume and mechanochemical treatment enables
transformation barriers to be overcome, producing a sequence of denser and more stable
phases. We are studying their vibrational density of states by cryogenic heat capacity
measurements and inelastic neutron scattering. Hybrid halide perovskites are of limited
thermodynamic stability, not just for reaction with water and air but with respect to
intrinsic decomposition; thus, tetramethylammonium lead iodide can spontaneously
disproportionate to tetramethyl ammonium iodide and lead iodide. Introducing
organic layers to form 2D perovskites aids stability, but there are thermodynamic limits
to the number of perovskite layers that can be incorporated.

Transport of Two-Dimensional Nanomaterials Sandwiched inside
Cell Membrane
Li-Tang Yan
Department of Chemical Engineering, Tsinghua University, Beijing 100084, China
Abstract
The transport of nanoparticles at the bio-nano interfaces is essential for many cellular
responses and biomedical applications. How two-dimensional nanomaterials, such as
graphene and transition-metal dichalcogenides, diffuse along the cell membrane is,
however, unknown, posing an urgent-important issue to promoting their applications in
biomedicine. Here we show experimentally and theoretically that the diffusive transport
of graphene nanosheets (GNs) sandwiched inside cell membrane varies from Brownian
dynamics to Lévy walks and even directional motion. Specifically, experiments
evidence the sandwiched graphene-cell membrane superstructures predicted by
simulations. Combined simulations and experiments identify sandwiched-GN-induced
pore in the leaflets of cell membrane, spanning unstable, metastable, and stable states.
Analytical model that rationalizes the regimes of these membrane-pore states fits the
simulations quantitatively, leading to a mechanistic interpretation of the emergence of
Lévy and directional dynamics. Our findings inform approaches to program
intramembrane transport of two-dimensional nanomaterials, and suggest design
principles for novel composite systems integrating such emerging nanomaterials inside
biological membranes.

Chemically tunable 2D Materials
Kristie J. Koski
Department of Chemistry, University of California Davis, Davis CA USA 95616
Abstract
Two-dimensional (2D) materials, such as layered chalcogenides, graphene, and oxides,
are an exciting new class of materials with extraordinary physical and chemical
behaviors. These high-performance materials have the potential to enable an entire fleet
of new technological applications ranging from electronics to photonics. To realize this
potential requires (i) the synthesis of novel, high-quality 2D materials, (ii) a broad
spectrum of chemical modification techniques, and (iii) a thorough understanding of
how these modifications control the material physics. In this presentation, I will show
new synthetic growth methods to create high-quality 2D chalcogenide materials
including a new semiconductor, Si2Te3. I will present a novel chemical method to
reversibly intercalate and deintercalate high concentrations of multiple, zero-valent
atoms into 2D materials. The zero-valent nature of the intercalant species allows for
high-density intercalation of metal atoms (Ag, Au, Co, Cu, Fe, In, Ni, and Sn)
effectively doubling the number of atoms of the material. This method achieves unique
physics including Pokrovsky-Talapov transitions, sliding charge density waves, and
modified phononic behaviors. Finally, I will show how this work achieves opto-
electronic application such as color-changing Smart Materials.

Abstract
Rhodium complexes catalyze the reactions of a wide variety of metal carbenes. We
have discovered that carbenes that lack electron-withdrawing groups, also known as
“donor/donor” carbenes, exhibit unique reactivity for enantioselective catalysis. We
have used this strategy for the synthesis of variety of 5- and 6-membered ring
products that are useful for the synthesis of drug discovery lead molecules and natural
products.

Surface Regulations of CeO2 for Heterogeneous Catalysis
Yongquan Qu*
Center for Applied Chemical Research, Frontier Institute of Science and Technology, Xi’an
Jiaotong University, Xi’an, 710049, P. R. China
Abstract
Ceria (CeO2) as a support, additive, and active component for heterogeneous catalysis
has been demonstrated with the great catalytic performance, which includes the
excellent thermal structural stability, catalytic efficiency, and chemoselectivity.1,2 In
general, the reversible Ce3+/Ce4+ redox pair and the surface acid-base properties
contribute to the superior intrinsic catalytic capability of CeO2, and hence yield the
enhanced catalytic phenomenon in many reactions. Particularly, nanostructured CeO2
is characterized by a large number of surface-bound defects, which are primarily
oxygen vacancies, as the surface active catalytic sites. Many efforts have therefore been
made on controlling the surface defects and properties of CeO2 by various synthetic
strategies and post-treatments. In this talk, I will give a brief overview of our efforts on
the surface regulations of CeO2 by wet chemical redox etching3 and synthetic pressure4
as well as their catalytic applications.5-7 The strong electronic metal-support
interactions between the metal and CeO2 with the abandant surface defects of oxygen
vacancy enable high catalytic activity and chemoselectivity for hydrogenation of
nitroarenes8 and quinolines9 and C-C coupling reaction.10

Characterization of the surface of ice: an atmospheric chemistry catalyst
Davide Donadio
Department of Chemistry, University of California, Davis, Davis, CA, 95616
Abstract
As Faraday realized by microscopic observations already in 1850, the surface of ice is
covered by a thin layer of liquid water even at temperatures far below melting. In spite
of the importance of ice surfaces in terrestrial and atmospheric physical and chemical
processes, the microscopic structure and dynamics of the disordered surface layer of
ice, commonly dubbed quasi liquid layer, is still largely unknown. In this work we use
classical and ab initio molecular dynamics simulations to characterize the structure and
dynamics of the quasi liquid layer at the low-index surfaces of hexagonal ice in the
temperature range that extends from 200 K to the melting temperature, and we
investigate how these properties are modified by the interaction with trace gasses or
ions. Our simulations identify a bilayer-by-bilayer discrete surface melting as a
function of temperature in pure ice models. Such melting behavior determines the shape
of the OH stretching band in infrared and non-linear sum frequency generation spectra
as a function of temperature. The adsorption of HCl induces further disordering at
stratospheric conditions. Ab initio MD simulations are combined with enhanced
sampling to discover the molecular mechanisms of ozone depletion reactions catalyzed
by the surface of ice.

Conjugated Polymer-Based Assembly Materials for Biomedical
Applications
Shu Wang*
Institute of Chemistry, Chinese Academy of Sciences, Beijing 100190, P. R. China
Abstract
In recent years, conjugated polymers (CPs) integrating recognition, imaging and therapeutic
functions have attracted more and more attention. A novel photodynamic therapy (PDT) system
was developed in which the photosensitizer is activated by chemical molecules instead of outer
light source. In this system, luminal, hydrogen peroxide and horseradish peroxidase (HRP)
were used as bioluminescent molecules and a cationic oligo (p-phenylene vinylene) (OPV) was
used as the photosensitizer. The excited OPV by BRET from luminol sensitizes oxygen
molecule in the surrounding to produce ROS that kill the adjacent cancer cells and pathogenic
microbes. The BRET system can work in vivo even in the deeper tissue, which comes over the
drawback of the deep tissue penetration for PDT with light irradiation. We designed an oligo(p-
phenylenevinylene) unit with thiol groups and a paclitaxelunit (OPV-S-PTX). The OPV-S-PTX
is capable of diffusing into cells, where π-π interactions lead to aggregation. Crosslinking of
the aggregates via oxidation of thiol groups preferentially occurs inside tumor cells because of
their higher internal reactive oxygen species (ROS) concentration. Crosslinked aggregates
effectively “chemically lock” the multichromophore particle inside the cells and this process
decreases the diffusion of the molecules out of the cell. The formation of the chemically locked
particles enhances drug efficacy and helps in reducing resistance. Recently, we have also
described a supramolecular antibiotic switch to reversibly “turn-on” and “turn-off” its
antibacterial activity, which provides a proof-of-concept to regulate antibacterial activity and
avoid accumulation of active antibiotics in the environment. The antibiotic switch relies on
supramolecular assembly and dis-assembly of cationic poly(phenylene vinylene) derivative
(PPV) with cucurbit[7]uril (CB[7]), which regulates their different interaction manners toward
bacteria. This supramolecular antibiotic switch could be a potential strategy to fight bacterial
infections and drug-resistance.

Mining Genomes for Lasso Peptides
James Link
Department of Chemical Engineering & Bioengineering, Princeton University
Abstract
Lasso peptides are a class of ribosomally synthesized and post-translationally modified
peptides (RiPPs) with diverse bioactivities including antimicrobial activity, receptor
binding, and enzyme inhibition. As their name indicates, they are defined by their
unique threaded structure that resembles a lasso or a slipknot. This talk will describe
our work in genome mining for novel lasso peptides. We have developed new
algorithms to rapidly identify lasso peptides from sequenced genome, growing the class
of lasso peptides from a dozen examples in 2012 to several thousand predicted peptides
today. I will discuss our structural and functional studies on several new lasso
peptides. In particular, our lab has discovered a novel enzyme, lasso peptide
isopeptidase, which specifically recognizes the knotted structure of the lasso peptide
and cleaves it into a linear form. The role of this enzyme in the biological function of
lasso peptides will be discussed.

Macrocyclization of Site-Specific Protein-Poly(α-amino acid) Conjugates
Hua Lu*
College of Chemistry, Peking University, Beijing, 100871, P. R. China
Abstract
Cyclization and polymer conjugation are two commonly used approaches for enhancing
the pharmacological properties of protein drugs. However, cyclization of parental
proteins often only affords a modest improvement in biochemical or cell-based in
vitro assays. Moreover, very few studies have included a systematic pharmacological
evaluation of cyclized protein-based therapeutics in live animals. On the other hand,
polymer-conjugated proteins have longer circulation half-lives but usually show poor
tumor penetration and suboptimal pharmacodynamics due to increased steric hindrance.
We herein report the generation of a head-to-tail interferon–poly (α-amino acid)
macrocycle conjugate circ-P(EG3Glu)20-IFN by combining the aforementioned two
approaches. We then compared the antitumor pharmacological activity of this
macrocycle conjugate against its linear counterparts, N-P(EG3Glu)20-IFN, C-IFN-
P(EG3Glu)20, and C-IFN-PEG. Our results found circ-P(EG3Glu)20-IFN to show
considerably greater stability, binding affinity, and in vitro antiproliferative activity
toward OVCAR3 cells than the three linear conjugates. More importantly, circ-
P(EG3Glu)20-IFN exhibited longer circulation half-life, remarkably higher tumor
retention, and deeper tumor penetration in vivo. As a result, administration of the
macrocyclic conjugate could effectively inhibit tumor progression and extend survival
in mice bearing established xenograft human OVCAR3 or SKOV3 tumors without
causing severe paraneoplastic syndromes. Taken together, our study provided until now
the most relevant experimental evidence in strong support of the in vivo benefit of
macrocyclization of protein–polymer conjugates and for its application in next-
generation therapeutics.

Organic boron compounds as novel fluorescent probes
Guoqiang Yang*
Institute of Chemistry, University of Chinese Academy of Sciences,
Chinese Academy of Sciences, Beijing, 100101, P. R. China
Organic boron compounds with electronic donor and/or acceptor group show sensitive
fluorescence with their environment. For the triaryl boron compounds, they give fluorescent
emission of typical intramolecular charge transfer (ICT) compounds due to the electron affinity
of the boron atom. These compounds have two emissive excited states and the energy difference
between them is small, so that a significant temperature effect is observed. Meanwhile, they
have relatively high fluorescence quantum yield due to the small size of the boron atom and its
crowed aryl surroundings. For their good stability and unique luminescent properties, triaryl
boron compounds are studied as novel luminescent probes for the detection of temperature, pH
value and special component in solutions and in bio-cells.

Using Mobile NMR Spectroscopy to Study Chemical Problems in a Factory
Environment
Matthew P. Augustine
Department of Chemistry, University of California, Davis, California 95616, United
States
Abstract
Modern permanent magnet and radio frequency electronics technology now make
NMR spectroscopy amenable to process control in real factory environments. In
comparison to large, expensive, laboratory anchored superconducting magnet-based
spectrometers, it is the decreased size and durability of systems based on these
technological advances that now allows NMR to provide real time feedback during
industrial processes. The factory environment presents an interesting spectrometer
building challenge as standard 5 mm diameter, glass tubes containing pure compounds
or simple mixtures are rarely encountered. Samples are typically well defined,
reproducible complex mixtures presented in metal pipes at ambient or elevated pressure
or in large aseptic metal containers. Early work involving the NMR study of industry
standard sealed “Coke” cans is extended here to study tomato spoilage in 1,000 liter, 1
ton aseptic containers with single sided magnets of varied construction and coil
arrangement. The design and construction of the recently deployed NMR based
tomato spoilage detector will be described. Other early NMR work involving the
study of aqueous geochemistry at up to 3 GPa pressure is also extended here to study
both food and biomass in a high-pressure processing (0.5 GPa) situation for the first
time.

Genetically Encoded Click Chemistry: New Tools for Protein-based
Materials
Wen-Bin Zhang*
College of Chemistry, Peking University, Beijing, 100871, P. R. China
Abstract
Genetically encoded chemistry provides versatile control over the process of
chemical reactions and the resulting materials. The spontaneous formation of an
isopeptide bond between a peptide tag and its protein partner is a genetically encoded,
cell-compatible, highly specific and efficient chemistry for protein/peptide conjugation,
as demonstrated in the chemically reactive pair of SpyTag/SpyCatcher.1 In this talk, I
will give a brief overview of our work in the development of genetically encoded
protein chemistry tools (especially those possessing features of click chemistry) and the
use of such tools to create bioactive materials. Through protein engineering, we have
successfully developed a chemical toolbox of genetically encoded chemical reactions.
The possibility to encode chemical information into protein sequences has allowed the
direct cellular synthesis of cyclic proteins, tadpole proteins, star proteins, and other
branched topologies.2 The reaction between proteins bearing multiple reactive groups
also lead to all-protein-based bioactive hydrogels, whose macroscopic properties are
fully genetically encodable.3 By combining this chemistry with protein folding, protein
catenanes and other complex protein topologies can be prepared.4,5 In general,
catenation was found to increase proteins’ stability toward proteolytic digestion and
thermal denaturation.6 It has thus opened new ways to engineer protein’s properties,
both in vivo and in vitro, which has general implications for protein-based materials.

Bioorthogonal Cleavage Reactions in Living Systems
Peng Chen*
College of Chemistry, Peking University, Beijing, 100871, P. R. China
Abstract
Employing small molecules or chemical reagents to modulate the function of an intracellular
protein of interest, particularly in a gain-of-function fashion, remains a challenge. In this talk,
I will introduce a “chemical decaging” strategy that relies on our developed Bioorthogonal
Elimination Reactions to control protein activation in living cells. These reactions exhibited
high efficiency and low toxicity for chemical decaging of the masked-lysine residue on
intracellular proteins, which is complementary to the previously used photo-decaging reactions.
In certain applications, particularly within live animals, small-molecule mediated chemical
decaging is highly desired and advantageous. We are currently employing this method to block
specific kinase’s activity in living cells, which allowed the subsequent gain-of-function study
of each kinase within the intracellular signaling transduction network. Together, our strategy
expanded the view of Bioorthogonal chemistry beyond ligation reactions, which may be
generally applicable for chemically rescuing of a given protein, thus manipulating its activity
within a native cellular context.

The Secret Life of the Genome: Repair of DNA base modifications
Sheila David
Department of Chemistry, University of California, Davis, California 95616, United States
Abstract
The DNA bases hold the informational content of DNA. Modified DNA bases are
considered “DNA damage” and have the potential to alter the coding properties and
cause deleterious DNA mutations. There is also a growing appreciation that DNA base
modifications may influence a broad range of cellular processes beyond mediating
permanent DNA mutations. DNA glycosylases play a key role in removing damaged
DNA bases as an initiating step in base excision repair (BER). We have focused
extensively on the repair of oxidized guanines, and the BER glycosylases MUTYH and
NEIL1. MUTYH is the human homolog of MutY and is a [4Fe-4S] cluster glycosylase
that targets removal of an undamaged adenine from 8-oxoguanine (OG):A mismatches.
In contrast, NEIL1 removes a broad range of oxidized guanine lesions, as well as
oxidized pyrimidines, and also is capable of removing lesions in a wide variety of
contexts including ssDNA and G-quadruplexes. Using a multi-pronged approach
including enzyme kinetics, structural studies and cellular assays, we have revealed key
features involved in the recognition and base excision activity of these two distinct
glycosylases. For example, we have recently revealed that the 2-amino group of OG
is a key feature for the initial detection of OG:A over T:A base pairs. My laboratory
also played an important role in the discovery of MUTYH-associated polyposis (MAP),
an inherited form of colorectal cancer, by revealing that the two most common MAP
variants have a hampered ability to recognize OG. We have continued to reveal
interesting features of MAP variants, and the location and dysfunction of disease-
associated variants has provided a window for revealing new features of MUTYH. We
also have shown that the hydantoin lesions Gh and Sp are the best-documented
substrates for NEIL1. In addition, we uncovered that there are two forms of the NEIL1
glycosylase resulting from mRNA editing (recoding) that have distinct differences in
enzymatic processing of DNA base lesions. More recently, we have revealed features
of the repair that are unique to a given NEIL1 substrate and the consequences of NEIL1
recoding. Comparing and contrasting the two glycosylases illustrates the “fine-tuning”
provided by DNA repair glycosylases to detect, mediate and respond to DNA base
modifications.

Abstract
m6A is the most prevalent internal modification in eukaryotic mRNA and preferentially occurs
at the consensus sequence [G/A/U][G>A]m6AC[U>A>C] with a non-stoichiometric ratio.
Although it was first found in 1970s, relative to DNA modifications, the research on m6A
lagged behind due to the lack of detection techniques for RNA modifications. Until 2011, the
discovery of FTO as an m6A-demethylase demonstrates m6A is a reversible and dynamic RNA
modification and reignites investigation of m6A. In 2012, two research group developed m6A
antibody immunoprecipitation-based sequencing method (termed m6A-seq or MeRIP) and
reported the whole-transcriptomic m6A maps. m6A is installed by a methyltransferase complex
(writer) with key subunits identified as METTL3 (Methyltransferase-like 3), METTL14 and
WTAP (Wilms tumour 1-associating protein). So far only two m6A demethylases (eraser), FTO
and ALKBH5 (AlkB homolog 5), have been characterized. m6A is recognized by reader
proteins (such as YTH family proteins) to regulate RNA fate, including mRNA stability,
splicing, nuclear export, translation, primary microRNA processing, and RNA-protein
interactions. These processes affect circadian rhythms, stem cell pluripotency, cancer stem cell
proliferation, RNA virus infection, sex determination in Drosophila, and so on, revealing that
m6A plays critical roles in various biological processes. However, the study of m6A methylation
in Arabidopsis thaliana has been limited to the m6A methyltransferase. Here we will discuss
our discovery and characterization of reversible m6A methylation mediated by demethylase and
read by m6A-binding protein in A. thaliana, and noticeable regulatory roles of these RNA
demethylase a reader in plant development especially floral transition. Our findings reveal
potential broad functions of reversible mRNA methylation in plants.

Sustainable Production of Biofuels and Bioproducts from Microalgae
Annaliese Franz
Department of Chemistry, University of California, Davis, 95618, USA
Abstract
Microalgae is a promising feedstock for sustainable production of biofuels and biochemicals;
However, production of fuel feedstocks from microalgae remains prohibitively expensive despite
significant advances in the field. The high costs of nutrients needed for cultivation is a challenge for
large-scale production. To address these challenges, we have investigated the use of nutrient-rich
wastewaters as well as the co-production of value added chemicals from microalgae-based biofuel
production systems. We have investigated the production of one class of valuable co-product;
bioactive lipids with. that can regulate diverse biological functions and are important to human
health. Bioactive lipids are expensive to produce using synthetic means or enzymatically by
fermentation so this provides a valuable opportunity to access these molecules while also using a
co-product strategy to reduce the cost of fuel feedstocks. We describe the development of analytical
methods to measure various lipids in microalgae, including bioactive lipids, and make the first report
of treatment conditions that induce the production of bioactive lipids. Several industrially relevant
microalgae strains have been investigated in this study to compare the production of bioactive lipids
under treatment conditions. Treatment of one strain of microalgae with a chemical trigger under
environmental nutrient stress increased the accumulation of a class of bioactive lipids by up to 400%.
The synergistic approach of utilizing a chemical trigger to enrich the content of bioactive lipids in
microalgae biomass uses methods congruent with current industrial cultivation practices. This
system provides a foundation for studying the mechanisms of formation for bioactive lipids in
microalgae and the development of a biological production route for specific classes of bioactive
lipids.

Non-equilibrium protocell models with “living” features
Dehai Liang*
Key Laboratory of Polymer Chemistry and Physics of the Ministry of Education, College of
Chemistry and Molecular Engineering, Peking University, Beijing 100871, China
Numerous strategies are now available to generate rudimentary forms of synthetic cell-like
entities; however, minimal progress has been made in the sustained excitation of artificial
protocells under non-equilibrium conditions to achieve dynamic features with life-like
properties. As a consequence, even the most highly integrated protocellular systems are
functionally compromised compared with basic life processes, which occur under a continuous
flux of energy and matter exchange. Thus, a major challenge in synthetic protocell research
involves the development of methodologies that enable the sustained activation of chemical
micro-ensembles such that they persist and function under non-equilibrium conditions.
Since electric fields exist both extracellularly and intracellularly, and play a role in
dynamical processes such as tissue morphogenesis and regeneration, we explore the
possibilities of creating non-equilibrium protocells in the presence of electric field. The
coacervate micro-droplets comprising polylysine and short single strands of DNA are formed
within a microfluidic channel. When electric field is applied, the protocells exhibit two dynamic
features: repetitive cycles of vacuolarization and fluid circulation. By taking advantage of the
interplay between vacuolization and circulation, we achieve dynamical fluctuations in size and
shape, chaotic growth and fusion, spontaneous ejection and sequestration of matter, directional
capture of solute molecules, and dynamic localization of an enzyme cascade reaction at specific
droplet locations. Our work represents a novel strategy to couple complex hydrodynamics,
matter exchange, and chemical reactivity within the interior of molecularly crowded coacervate
micro-droplets, and as such provides a step towards the non-equilibrium functionalization of
synthetic protocells capable of biomimetic operations.

Abstract
Over 200 molecules have been detected to date in the interstellar medium and in
circumstellar shells. Yet despite considerable advances in the capabilities of
astronomical telescopes, a detailed understanding of the formation and destruction of
molecules in space remains elusive. Accurate modeling of astrochemical processes
requires laboratory measurements of molecular spectra and of chemical reactions under
conditions relevant for astrophysical environments. Developments in broadband
microwave technology over the past decade have enabled rotational spectroscopy to
become a highly versatile technique for molecular identification and quantitation in the
gas phase. We have combined a Ka-band chirped-pulse Fourier transform microwave
spectrometer with the uniform supersonic flow generated by a pulsed Laval nozzle to
investigate the kinetics of astrophysically important chemical reactions between
radicals (formed by pulsed laser photolysis of a suitable precursor) and neutral polar
molecules. The current status and prospects of the technique are discussed.

Energy Transfer in the X-ray Regime: X-ray Induced Energy Transfer (XIET)
Ting Guo
Department of Chemistry, University of California, Davis, CA 95616
Abstract
In this talk, the results of a systematic theoretical study of a new phenomenon of X-
ray Induced Energy Transfer (XIET) within the purview of X-ray nanochemistry are
presented. X-ray nanochemistry explores utilization of nanostructures for the purpose
of absorbing X-rays to drive actions such as catalytic DNA strand breaks or
polymerization enabled at locations buried deep in opaque objects. XIET occurs
between a strongly X-ray absorbing nanomaterial such as one or more gold
nanoparticles and a weakly X-ray absorbing nanomaterial such as a hollow silica
nanoparticle filled with water; part of the energy absorbed by the former can be
transferred to the latter when the two are positioned sufficiently close together. The
strongly X-ray absorbing nanomaterial which releases energy after X-ray absorption
are called donors and the weakly X-ray absorbing nanomaterial receiving energy from
the donors are called acceptors. XIET related concepts were studied in the past, but in
a more general sense of energy deposition in theoretically defined volumes surrounding
donors, rather than in nanoscale acceptors as explored in this work. The results of
theoretical study of XIET as a function of dimension, composition, configuration and
orientation of donors and acceptors, number of donors, and X-ray energy are given.
Results of relative and percentage XIET efficiencies are discussed. The results
presented in this talk provide a theoretical framework to guide future experimental
XIET studies.

host-guest interaction, hydrogen-bond dynamics and basic chemical reactions. Because
it is constructed from a single molecule, each device can monitor individual binding
events in real time. This methodology demonstrates a connection between electrical
conduction and chemistry/biology that offers a glimpse into the future of integrated
multifunctional sensors and devices.

Ultrafast Direct Electron Transfer at Organic Semiconductor and
Metal Interfaces
Wei Xiong
University of California- San Diego, 92093
Abstract
In this talk, I will give an overview of a few state-of-the-art ultrafast nonlinear
spectroscopy works in my group, spanning from model electrochemical catalysis,
optoelectronic devices to novel molecular photonic materials. I will particularly focus
on a recent study on ultrafast direct interfacial charge transfer. The ability to control
direct electron transfer can facilitate the development of new molecular electronics,
light-harvesting materials and photocatalysis. However, it has been rarely reported and
the molecular conformation-electron dynamics relationships remain unclear. Here, we
describe direct electron-transfer at buried interfaces between an organic polymer
semiconductor film and a gold substrate, by observing the first dynamical electric-field-
induced vibrational sum frequency generation (VSFG). In transient electric-field-
induced VSFG measurements on this system, we observe dynamical responses (<150
fs) that depend on photon-energy and polarization, evidencing that electrons are directly
transferred from Fermi level of gold to LUMO of organic semiconductor. Transient
spectra further reveal that, although the interfaces are prepared without deliberate
alignment control, a sub-ensemble of surface molecules can adopt conformations for
direct electron transfer. DFT calculations support the experimental results and ascribe
the observed electron transfer to a flat-lying polymer configuration in which electronic
orbitals are found to be delocalized across the interface. The present observation of
direct electron transfer at complex interfaces as well as the insights gained into the
relationship between molecular conformations and electron dynamics will have
implications for implementing novel direct electron transfer in energy materials.

Probing interfacial water at submolecular level by scanning probe microscopy
Ying Jiang*
International Center for Quantum Materials, Peking University, Beijing, 100871, P.
R. China
Abstract
Interfacial water is ubiquitous in nature and plays an essential role in a broad spectrum
of physics, chemistry, biology, energy and material sciences. One of the most
fundamental issues is the characterization of H-bonding configuration formed on
surfaces and H-atom transfer through hydrogen bonds. Ideally, attacking this problem
requires the access to the internal degrees of freedom of water molecules, i.e. the
directionality of OH bonds. However, it remains a great challenge due to the small size
of hydrgen. In this talk, I will present our recent progress on the development of new-
generation scanning probe microscopy/spectroscopy (SPM/S) with ultrahigh sensitivity
and resolution, and its application to surface water. I will foucus on how to achieve
submolecular-resolution imaging [1,2] and single-bond vibrational spectroscopy [3] of
single water molecules via controlling tip-water coupling. Those technical advances
provide us unprecedented opportunity to identify the topology of H-bonding
configuration [4], track the proton dynamics [5], and assess quantitatively the nuclear
quantum effects (NQEs) of H bond [3,5]. The submoleuclar-level studies of ion
hydrates and two-dimensional ice structures will be also briefly introduced in the end.

New Advances in 3D Nanoprinting
Gang-yu Liu
Department of Chemistry, University of California, Davis, California 95616, United States
3D printing has been a very active area of research and development (R&D) in the context of
additive manufacture, due to its capability to produce 3D objects by design. Current 3D nanoprinting
technology pushes the spatial limit to micrometer scale. Further miniaturization represents a major
challenge in current R&D effort in 3D printing. This work reports new advances in miniaturizing
3D printing to nanometer scale using scanning probe microscopy in conjunction with local material
delivery such as nanofluidics.[1] Using various materials, the concept of layer-by-layer nanoprinting
by design have been demonstrated.[1-2] Nanometer precision is achieved in all three dimensions,
as well as in inter-layer registry, as shown in Figure 1. The approach and results provide a new and
general platform for conducting scientific research in designed 3D nano-environments, as well as
enabling production of new nanomaterials and scaffolds for photonics, devices, biomedicine and
tissue engineering.[3-4]

Hybrid Voltage Indicators for Imaging Neural Activity
Peng Zou*
College of Chemistry, Peking University, Beijing, 100871, P. R. China
Abstract
Membrane voltage is an important biophysical signal. Optical mapping of membrane voltage
enables investigation of electrical signaling at high spatial resolutions and with high throughput.
In this talk, I will describe a recently developed fluorescent voltage indicator scaffold (Flare1)
that builds upon the site-specific modification of microbial rhodopsin with organic fluorophores.
Flare1 achieved 36% ΔF/F per 100 mV voltage change with sub-millisecond response kinetics,
thus representing one of the most sensitive and fastest orange-colored voltage indicators. This
technique has enabled observation of long-range electrical coupling among mammalian cells
that was mediated via gap-junctions. Combining the superior brightness and photostability of
small molecules with genetic targeting of microbial rhodopsin proteins, this design strategy can
be extended for developing novel fluorescent indicators.

Chemistry of atmospheric particles
Peter B. Kelly
Department of Chemistry, UC Davis, Davis, CA 95616
Abstract
Aerosols collected in Oslo with an aerodynamic size below 2.5 µm were
gravimetrically weighed to acquire mass concentrations and analyzed by Accelerated
Mass Spectrometry to separate the particulate bound carbon as biogenic or fossil
derived. Results were compared to levoglucosan measurements and were associated
with meteorological factors, human population behavior patterns and diurnal variations.
Overall colder temperatures lead to higher concentrations of particle bound carbon and
the biogenic fraction nearly doubles as the temperature is lowered and inversion layers
are formed compared to the fossil carbon levels. BC had the highest linear correlation
coefficient with temperature indicating the strong temperature dependence of aerosol
mass from wood burning. Non-carbon species were not linearly dependent on
temperature. 12C/14C isotopic analysis of PM2.5 gave on average a biogenic carbon
fraction of 20 +/- 5 %, which is estimated to equal 43 - 53 % total wood burning
contribution. The conversion factor between BC mass and the total wood burning mass
was estimated to be between 2.1 – 2.4. At night all the aerosol fractions are linearly
dependent on the average temperature and during the day the relationship is non-linear.
Radiocarbon and levoglucosan measurements measured in Oslo during the sampling
period agree well. Further examination of the linear correlation between decreasing
temperature and carbon revealed that total carbon concentrations for each sample could
be modeled as a function of the hours below -4 oC as a critical temperature reflecting
all the parameters playing a part in aerosol formation in Oslo during the winter.
