Welcome!
On behalf of the South African Chemical Institute and the Local Organising
Committee of SACI 2015, it is a pleasure to welcome you to the 42nd
National
Convention of the South African Chemical Institute. The Convention is the
highlight of the Institute’s calendar and this year the event is being held at the
Elangeni Hotel in Durban. The Convention was last held in Durban in 2006.
The aim of the Convention is to provide a conducive atmosphere for leading
chemists in South Africa, and from elsewhere, to meet and present their latest
research results, to discuss matters of common interest and to show that
“Chemistry Shines”, particularly in 2015, which has been declared the
International Year of Light! No less important, are the opportunities for social
interactions, to renew old friendships and to make new ones.
The programme includes several eminent plenary speakers from the
Netherlands, Italy, Spain, Portugal, Canada, USA and India. In addition, six
SACI Award lectures will be given including two prestigious “Gold Medal”
lectures. We also have Keynote Lectures from local researchers and
approximately 140 oral and 140 poster presentations. The presentations cover
all aspects of chemistry including newer areas of research such as
Nanotechnology and Green Chemistry.
Particularly pleasing is the enthusiastic response from the younger chemists.
They represent the future leaders in the discipline whether in academia, industry
or government.
The venue for the Convention is the beautiful seaside city of Durban. With its
warm climate and extensive beaches it is a major tourist centre. The city is also
the busiest port and the second most important manufacturing hub in South.
Durban is renowned for its rich mix of African, Indian and European cultural
influences. We hope you will be able to explore what the city and surrounding
areas offer.
We hope the Convention will provide a rewarding, exciting and stimulating
experience for all the delegates and that you will enjoy your time in Durban!

Helder Marques
2015 Gold Medallist of the South African Chemical Institute Professor of Bioinorganic Chemistry
School of Chemistry
University of the Witwatersrand
Johannesburg
South Africa
Topic: The Coordination Chemistry of Co(III) in the Cobalt
Corrins
Helder Marques is Professor of Bio-inorganic Chemistry and Dean of the Faculty of Science at the
University of the Witwatersrand. After graduating with both an Honours degree in chemistry and
a Higher Diploma in Education from the University of the Witwatersrand, he spent two years as a
high-school teacher before returning to his alma mater to complete a PhD degree, which was
awarded in 1986. His doctoral research on the thermodynamic and kinetic properties of model
complexes for metalloproteins laid the foundation for an abiding interest in phenomena at the
interface between inorganic chemistry and biology. After spending a year as a post-doctoral
fellow at the University of Texas at Arlington, he was appointed in 1987 to a lectureship at the
University of the Witwatersrand. A spectacular combination of talents as a teacher, researcher and
administrator resulted in his appointment to a Personal Chair (1998), Headship of the School of
Chemistry (1999) and Deputy Deanship in the Faculty of Science (1997), all within the space of a
dozen years of his appointment to the staff of Chemistry. His achievements as a teacher were
acknowledged when he received both the Convocation Distinguished Teachers’ Award in the
Faculty of Science and the Vice-Chancellor’s Award for Teaching in 1992. The South African
Chemical Institute recognised his research potential by the award of its Raikes Medal (awarded to
9
an outstanding chemist under the age of 35) in 1989. In the same year he won the Vice-
Chancellor’s Research Award from the University of the Witwatersrand. It is worth noting that
Professor Marques was the first person to achieve the “double” of the Vice-Chancellor’s Teaching
and Research Awards at the University of the Witwatersrand. Professor Marques stepped down as
Head of the School of Chemistry at the end of 2007 only as a result of the award of the DST/NRF
Research Chair in Bioinorganic Chemistry, which required him to concentrate on research.
Despite this move, he maintained a substantial presence in the affairs of the Faculty of Science (as
Assistant Dean for Research, then as Deputy Dean) and in the University (as Deputy Chair of
Senate, among many other functions). He was appointed as Dean of the Faculty of Science in
2013. Professor Marques’s current research focuses on exploring the relationships between
structure and function in biologically important compounds containing metal ions, for example,
corrinoids such as vitamin B12, and porphinoids such as hemoglobin and related heme proteins;
and he has become internationally known for his use of computational methods to model and
predict such relationships. Both national and international collaborations have seen him applying
these methods to problems as diverse as defining parameters for molecular mechanics calculations
on metalloporphyrins, and the interaction of antimalarial drugs with haemoglobin. His impressive
curriculum vitae includes almost 150 publications in journals of international repute (including
several in J. Am. Chem. Soc., regarded by some as the ne plus ultra for publications in chemistry),
several book chapters, a host of invited or keynote lectures at local and international conferences,
frequent invitations to act as referee for prestigious international journals, and supervision of many
MSc and PhD students. He has an h index of 31; and over 2100 citations (excluding self-citations)
to his published research. He currently enjoys a B2 rating from the NRF. Among other forms of
professional recognition have been election to Fellowship of the Royal Society of South Africa
(2004), the award of the Merck Medal of the South African Chemical Institute (2006), and election
to Fellowship of the South African Chemical Institute (2013).

Catalytic Inhibitors of Human Topoisomerase I Professor Munro received his B.Sc Hons. degree in Chemistry in 1990 from WITS University
(University of the Witwatersrand, Johannesburg, South Africa). He completed his Ph.D. in the
Department of Chemistry at WITS in 1995 (graduating in April 1996), where his thesis work,
supervised by Prof. Helder Marques, focused on physical and computational studies of heme-
peptide model systems for heme proteins and other metalloporphyrins. He then joined Professor
Robert Scheidt’s laboratory at the University of Notre Dame in Indiana (Department of Chemistry
& Biochemistry) in November 1995 and spent 18 months as a post-doctoral researcher working on
the synthesis, characterization, X-ray structures, and molecular simulations of iron porphyrins and
10
related macrocycles with unusual conformations. In 1997 he joined the Department of Chemistry
at the University of Natal (South Africa), where he continued to work on porphyrin and other
pyrrole compounds as well as luminescent complexes of Pt(II) (the latter incollaboration with Prof.
John Field). He has received numerous awards over the years at this institution, including the
National Research Foundation (NRF) President’s Award (2000), the Vice Chancellor’s Research
Award (2007), and the Raikes Medal of the South African Chemical institute in 2008. In
2011/2012 Professor Munro held a Visiting Fulbright Scholarship at the University of Central
Florida (College of Medicine) working with Prof. Mark Muller on delineating the mechanism of
action of a new class of anticancer metallodrug compounds invented in his laboratory in South
Africa. Several companies (De Beers, Avitronics, SASOL, AuTEK BioMed) and the NRF have
supported his research over the last decade. His current work is also indirectly supported by the
NIH (USA) through their Developmental Therapeutics Program (DTP).

Macromolecules for real-life applications It is a great honour to present Prof Bert Klumperman, one of the top-3 highest rated chemists in
South Africa, as judged by the rating system of the NRF. He started his career in 1985 with an
appointment in an industrial research lab in the Netherlands. Although he decided nine years later
to pursue an academic career, his desire to utilize polymer chemistry for developments of practical
relevance has continued. Apart from his more than 160 scientific publications, Bert is co-inventor
on 16 patents and patent applications. Since he started in his current position as a Research Chair
holder at Stellenbosch University in 2007, his research has strongly moved in the direction of bio-
related topics. Two of his most significant contributions over the past years are the development
of a permanent antimicrobial material that has potential in water purification, and an antimalarial
polymer-peptide conjugate that has proven activity against chloroquin-resistant malaria parasites.
Together with the Tech Transfer Office Innovus of Stellenbosch University, Bert is currently busy
to investigate the possible commercialization of these and other developments from his group.
Based on his track record, the continuous stream of valuable patent applications and especially his
recent innovative contributions, Prof Klumperman is a worthy recipient of the 2015 Sasol
Chemistry Innovator of the Year Medal.

Pre-Conference Workshops
Workshop: Short Course on Inductively Coupled Plasma-Optical Emission
Spectrometry (organized in conjunction with the South African Spectroscopic Society)
Presenters: Dr Johann Fischer (Sasol Group Technology) and Dr Ljiljana Marjanovic (SGS
South Africa (Pty) Ltd)
Date: Sunday, 29 November 2015
Time: 9h00-13h00
Abstract:
This course aims at giving a quick overview of the basics of ICP-OES as an analytical
technique. It will cover all the aspects normally found in a BSc Hons course on ICP-OES but
not to the same depth. The focus would be to inform and create awareness with the ICP-OES
user on what lies behind the pretty shining plasma. A user who is aware of what is happening
to his sample in order to produce a result, is a user who will pay attention to detail and not
make silly mistakes in handling his sample or not take shortcuts in preparing his calibration
which will only lead to useless information generated on a very expensive piece of equipment.
Learner participation will be widely welcomed to ensure that each participant will benefit
from a personal and relevant enrichment of his/her knowledge of ICP-OES.
COURSE CONTENT:
ICP-OES
What can ICP-OES do?
OES vs AAS
What is emitting?
Emission sources
Sample Introduction
Spectrometer types
15
Optimization of parameters
Analytical performance - Detection limits, Working range, Accuracy
Calibration and causes of drift
Spectral interference and Line selection
SAMPLE DIGESTION
Due to the need for every solid sample to be brought into solution before being analysed on the ICP-
OES, the presenters felt that sample digestion forms an integral part of the course and an overview of
the most commonly used sample digestions techniques will be discussed. Three of these most
commonly used sample digestion techniques:
Heating with aqueous strong acids (open vessel and a microwave)
Fusion with alkali salts
High temperature ignition in air or oxygen
will be discussed, together with their advantages and limitations. Each technique will be discussed
using some examples such as refractory ores, coal, pure metals, PGM prills, etc. Attendees will also
have an opportunity to be introduced to some of the technological advances in the digestion procedure
such as semi-automated digestion of PGM prills, that can also be applied to the other types of
digestions
16
Workshop: Green Chemistry
Presenter: Dr Mary Kirchhoff, American Chemical Society
Date: Sunday, 29 November 2015
Time: 14h00-17h00
Abstract:
This half-day workshop will provide an introduction to green chemistry. Green chemistry is
our discipline’s unique contribution to sustainability, a concept embraced by the chemical
industry because it makes good business sense to be environmentally and socially responsible,
as well as profitable. Life-saving pharmaceuticals can be produced while minimizing the
amount of waste generated, plastics that biodegrade can be synthesized from plants, and
reactions can be run in water rather than in traditional organic solvents by applying green
chemistry principles to chemical products and processes. Many chemists want to contribute
to a sustainable planet, and green chemistry provides an avenue for them to apply their
science to the quest for sustainability. The workshop will engage delegates in lectures, small
group discussions, and case studies, enabling participants to apply green chemistry to real-
world scenarios.
