Art in itself is a journey of self-exploration; with a global pandemic raging, art lovers can now explore this journey virtually. The Johannes Stegmann Gallery at the University of the Free State (UFS) is happy to announce the (second) virtual exhibition of Leeto: a Sam Nhlengethwa Print Retrospective until 4 September 2020.

The exhibition features a collection of Sam Nhlengethwa’s print work to be interrogated, his artistic evolution to be mapped out, and his personal aesthetics to be interpreted, while surveying this renowned artist’s print work from 1978 to 2018.  The underlying theme of the exhibition is jazz, an early influence in Nhlengethwa’s works from the underground jazz community of the townships. His brother was a jazz musician and he started collecting jazz records from the early age of 17.

Leeto is a Setswana/Sesotho word for ‘journey’ and, as the word suggests, the exhibition explores the ongoing artistic footsteps of the artist. The collection was curated by Boitumelo Tlhoaele, a doctoral fellow in the Africa Open Institute for Music, Research, and Innovation at Stellenbosch University.

About the artist: 

Nhlengethwa began his career in 1976 during one of South Africa’s most tumultuous socio-political eras. In 1978, he completed a two-year diploma at the Evangelical Lutheran Church Art and Craft Centre, Rorke’s Drift, KwaZulu-Natal, where printmaking was a prominent feature of the centre’s activities. Nhlengethwa’s work spans a variety of mediums, from painting, drawing to collage, and some of his works have been translated into tapestries. One of his big cityscape works was translated into a mosaic. In addition to all the afore-mentioned mediums, Nhlengethwa also produced an impressive and sizeable body of printmaking works. 

He has collaborated with several South African printmaking studios, such as The Artists’ Press, Artist Proof Studio, David Krut Print Workshop, LL Editions Fine Art Lithography Studio, MK and Artist Print Workshop, Mo Editions Printmaking Studio, and Sguzu Printmaker’s Workshop. Since 1994, he has produced 163 prints in collaboration with The Artists’ Press, making it his longest and most productive affiliation.

UFS boasts with most advanced chemical research apparatus in Africa 

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie.  The NMR is used to analyse molecular structures. 

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa.  The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research.  We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard.  Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around.  I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million.  With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level.  Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes. 
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.  
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry.  These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples. 

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
