UFSAfricaWeek Make this Africa Day a day of reflection - Dr Stephanie Cawood
Dr Stephanie Cawood is the acting Director of the CGAS

On 25 May 2018, we celebrate the 55th Africa Day since the Organisation of African Unity (OAU) was formed on this day in 1963. The conception of Africa Day, however, goes back to 1958 to the First Conference of Independent African States held in Accra, Ghana, hosted by Kwame Nkrumah. It was at that conference where Africa Freedom Day was first proclaimed and celebrated on 15 April to commemorate the progress of the African liberation movement as more and more African states gained independence. When more than 30 heads of state of independent African countries met in Addis Ababa, Ethiopia, to form the OAU (now the African Union) on 25 May 1963, African Freedom Day was dubbed African Liberation Day and moved to May. Today, known as Africa Day, it is commemorated across the African continent and the diaspora. 

What is the significance of Africa Day more than 50 years after its inception? African countries may have been liberated, but freedom is often qualified and limited by poverty persistent conflict, poor governance, neopatrimonialism, intolerance and other social injustices? Seen through a gender lens, one may well ask whether we have anything to celebrate when African women and sexual minorities carry such a heavy burden in daily struggles for survival and bear the brunt of persistent conflict. 

On this Africa Day, let’s rejoice in all the progress made since that very first commemoration. Let’s revel in all the vibrant cultural diversity in Africa and its diaspora, but let’s make this Africa Day a day of remembrance and reflection. As a day of remembrance, Africa Day should remind us of the liberation struggles that came before and it should prompt us to reflect on the struggles that remain in areas like gender equality and LGBTQI rights, poverty and sustainable livelihoods, social and environmental injustice, economic dependency, and conflict and what we can do to help effect change for the better. To quote an African proverb, “Use your tongue to count your teeth” for it is only through deep reflection that one will realise what needs to be done and how one should do it.

Prof Hendrik Swart richly contributes to research of phosphors

Since his appointment as the South African Research Chairs Initiative (SARChI) Chair, there has been a sharp increase in the number of papers and publications by Prof Hendrik Swart, Senior Professor in the Department of Physics at the University of the Free State (UFS). From January this year, he has already published 78 articles. Some of the journals that has published his work, includes:

• Nanotechnology (impact of 3.67)
• Dalton Transactions (impact of 4.097)
• Sensors and Actuators B: Chemical (impact 3.84)

“My biggest success, however, is the powerful group of researchers we have built over the years. Staff, postdocs and students – without them it would have been impossible. I am therefore much indebted to my groups on both the Bloemfontein and Qwaqwa Campuses.

“The good apparatus we acquired via a sponsorship from the National Research Foundation and Sasol is also one of the main reasons for this. The financial support I get from the university’s research office is of course also a contributing factor,” he says.

For the past 20 years, Prof Swart has been conducting research on any substance that glows. “I only adjust the focus to fit in with current trends,” he says.

Prof Swart believes that his research will make a contribution to the fundamental knowledge about phosphors, as well as to the training of good students for the academic and industrial world on the outside. For the man on the street, his research translates into better, brighter lights that use less energy.

His more recent research focuses on the development of nano-phosphors for light-emitting diodes (LEDS) and organic light-emitting diodes (OLED).

Prof Swart has presented papers on his research not only nationally, but all over the world – including countries in Europe and the East. Some of the most recent papers presented by him and his colleagues/postgraduate students include:

• Applications of AES, XPS and TOF SIMS to phosphor materials at die 15th European Conference on Applications of Surface and Interface Analysis 2013 in Forte Village Resort, Sardinia, Italy.
• Luminescent properties of phosphor nano thin films at the first International Symposium on Nanoparticles/Nanomaterials and Applications in Caparica (Lisbon, Portugal), where he was an invited speaker.
• Role of surface and deep-level defects on the emission of nano metal oxides at the 2014 NanoAfrica international conference, Vanderbijlpark, South Africa, where he delivered the keynote address.
• PHI systems and their modifications at KOVSIES at the PHI European User Meeting in Ismaning (Munich), Germany, where he was invited to speak.

Prof Swart also delivered the keynote address at the SETCOR International Conference on Smart Materials and Surfaces in Bangkok, Thailand. His lecture was titled, ‘Role of surface and deep-level defects on the emission and degradation of phosphor materials’.
