A Virtual celebration of Africa Month

On 25 May 2020, Africa will celebrate the 57th anniversary of the founding of the Organisation of African Unity. A central tenet of the organisation, which was the predecessor of the African Union, is African solidarity. Member states undertook to coordinate and intensify their cooperation and efforts to achieve a better life for the people of Africa. The University of the Free State (UFS) has a long tradition of commemorating Africa Day and the ideas underpinning it. Every year, diverse events aimed at advancing African unity and solidarity take place during Africa Month – traditionally, the highlight is the Africa Day Memorial Lecture hosted by the University's Centre for Gender and Africa Studies

This year, celebrating African unity through significant events involving the physical presence of a large number of people, will likely be impossible. COVID-19 is ravaging the world and Africa may become one of the world regions worst affected by the consequences of the virus. Social distancing may be difficult to achieve in a continent with densely populated urban centres that often feature large informal settlements. Besides, the economies of African nations are not as robust as those of other world regions. The challenge that Africa is facing, appears to be one that can only be mastered by its people acting in solidarity and unity. The continent has already developed an Africa Joint Continental Strategy for COVID-19 Outbreak to combat the virus, and an Africa Taskforce for Coronavirus has been established. The ideas of African togetherness and the underpinning philosophy of Ubuntu may be critical for strengthening African solidarity at a time when it may be more relevant than ever.

The commemoration of Africa Day takes a different theme each year. This year, the UFS 2020 Africa Month celebrations will take a virtual format, with the theme of ‘Africa together forever’ underpinned by the COVID-19 global pandemic. The theme is particularly significant considering the context of the African continent; and only through the demonstration of solidarity and unity can Africa overcome the challenges of the global pandemic.

The University will host a variety of cultural and intellectual contributions on the dedicated UFS virtual Africa Month website. On Africa Day (25 May 2020), a virtual Africa Day function, which will be posted on the website, will conclude the Africa Month commemorations.

The diverse contributions to the 2020 virtual Africa Month activities will highlight the University’s commitment towards creating a diverse, challenging intellectual environment. The UFS strives as a research-led university, to provide an environment in which new ideas are incubated and debated; contributing towards its transformation process and African unity.

What do diamonds, chocolates, bugs and almost 30 Nobel Prizes have in common? Crystallography
2014-10-15

 

Some of the keynote speakers and chairpersons at the third world summit in the International Year of Crystallography (in Africa) were, from the left, front: Profs Abdelmalek Thalal (Morocco), Prosper Kanyankogote (University of Kinshasa, Democratic Republic of the Congo); Habib Bougzala (Tunisia), Santiago Garcia-Granda (IUCr, University Oviedo, Spain), Michele Zema (IYCr 2014, Italy/UK) and Dr Jean-Paul Ngome-Abiaga (UNESCO, Paris, France); back: Dr Thomas Auf der Heyde (Acting Director-general, South African Department of Science and Technology); Dr Petrie Steynberg (SASOL) and Prof André Roodt (UFS, host).

The third world summit in the International Year of Crystallography (in Africa) was hosted by Prof André Roodt, Head of the Department of Chemistry and President of the European Crystallographic Association,  at the University of the Free State in Bloemfontein.

A declaration with and appeal to support crystallography and science across Africa, was signed.

When one mentions 'Crystallography', or more simply 'crystals', what comes to mind? Diamonds? Perhaps jewellery in general? When thinking of crystals and Crystallography, you will need to think much bigger. And further – even to Mars and back.

Crystallography refers to the branch of science that is concerned with structure and properties of crystals. The obvious examples would include cut diamonds, gemstones such as amethysts, and ‘simple’ crystals such as selenite and quartz.

But have you thought about the irritating brown scales at the bottom of your kettle? The sand in your shoes? The salt over your lamb chops or the sugar in your coffee? All crystals. From egg shells to glucose, from bugs and insecticides to additives in food – even the compounds in chocolate – all fall under the close scrutiny of Crystallography.

The breakthroughs this field of science has produced have led to almost 30 Nobel Prizes over the years.

Determining the structure of DNA by crystallography was arguably one of the most significant scientific events of the 20th century. Different diseases have been cured or slowed by medicines obtained based on crystallographic studies. These include certain cancers, HIV/Aids, Tuberculosis and Malaria. Biological Crystallography enables the development of anti-viral drugs and vaccines.

This field of science influences our daily lives in virtually immeasurable ways. Here are but a few areas of study and development Crystallography contributes to:

•    LCD displays;
•    cellular smartphones;
•    insects and insecticides;
•    additives and products in foods;
•    improved effectiveness and security of credit cards;
•    new materials to preserve energy;
•    better gasoline with less by-products;
•    identify colour pigments used in paintings from the old masters, indicating if it’s an original or an imitation; and
•    beauty products such as nail polish, sun-block, mascara and eye shadow.

Crystallography is also currently used by the Curiosity Rover to analyse the substances and minerals on Mars.

Crystals and Crystallography form an integrated part of our daily lives – from bones and teeth to medicines and viruses, from chocolates to the blades in airplane turbines. Even down to the humble snowflake.
