Dr Ocaya
Dr Richard Ocaya’s research addresses the skills development and transfer millennium goal of many governments globally.

With the Fourth Industrial Revolution becoming a reality, Dr Richard Ocaya’s research is receptive to the fact that Africa and the world need to re-imagine their research. His research focuses on electronic instrumentation design for scientific measurements, computational physics on atomic nano-atomic structures, and semiconducting organic compounds materials built on silicon to realise Schottky devices.

Software developer 
“I develop most of the instrumentation that I apply in my research – both software and hardware,” said Dr Ocaya, a Physics Lecturer and Programme Director: Physics and Chemistry on the UFS Qwaqwa Campus.

“I am active in scientific computing through the computing cluster and software development, mathematical physics for material science modelling, and embedded instrumentation design using microprocessors. I also have deep interest in radio and data telemetry, in which I hold a South African patent issued in 2013. My present international collaborations are with like-minded researchers in similar fields in Saudi Arabia, Turkey, Japan, Egypt, South Korea, and the United States,” he added.

How does his research talk to the real world?
“The driving principle of all areas of my research has always been to deploy cutting-edge research to actual, real-world applications for the immediate betterment of Africans. The areas of my research align closely with the millennium goals of many governments globally, including the Republic of South Africa. These goals pertain to skills development and transfer that position us to better address the challenges of energy, water, and other priorities.”

Dr Ocaya is currently co-promoting a PhD student, having previously supervised one PhD, two MSc, and more than twenty honours students. He is a self-taught electronics and computer programmer, whose curiosity led him to question ‘the voices and music coming from a box; a radio’. “In my quest to satisfy my curiosity, I collected many discarded devices, took them apart, and tried so many circuits, only to have them fail because the theory was lacking. After thousands of failed projects and with me barely thirteen and in lower secondary school, my first ever project actually worked,” he said.

NRF-rating
He is the author of the book Introduction to Control Systems Analysis using Point Symmetries: An application of Lie Symmetries, which is available in all major bookstores such as Amazon, in both print and e-book format. He is a C3 NRF-rated researcher whose work makes a pioneering contribution to the new and growing field of phononics, an independent field of the now established photonics.

“This field will someday lead to improved energy-storage devices and faster processors due to more efficient heat removal from nanodevices,” he concludes.

Dr Alba du Toit, a junior lecturer in Consumer Science at the University of the Free State (UFS), presented her research at the recent IX International Congress on Cactus Pear and Cochineal at the University of Chile in Santiago, Chile. The congress was themed, “CAM Crops for a Hotter and Drier World”.

Dr Du Toit, Prof HO de Waal and Dr Maryna de Wit, from the Faculty of Natural and Agricultural Sciences at UFS, attended the five-day conference held between 26 and 30 March 2017.

Congress a platform for networking
The congress, held every three years since 1993, gathers cactus pear researchers, growers and processing managers from Europe, the Americas, Asia and Africa to review current research trends by networking to form new collaborations that could lead to increased efficiency and shared knowledge. They also present new findings and plan for future research.

Great achievements for researchers
Dr Du Toit said: “My research on cactus pears focused on the utilisation of the slimy substance found in the cactus cladodes as a functional ingredient in innovative nutraceutical food products”. Functional foods are foods that promote health or prevent disease through adding or omitting specific ingredients. She also received the International Society of Horticultural Science award for best student oral presentation.

Dr De Wit also presented her research and was appointed coordinator for Agro-Processing and Post-Harvest Technology at the congress.

Dr Herman Fouché, Affiliated Researcher at the Department of Soil-, Crop- and Climate Sciences at UFS, developed “kuilmoes”, a type of silage from pulped cactus pear fruit, mixed with lucerne, in collaboration with Prof de Waal, which was also presented.at the congress.
