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.

Equipment worth R23 million to carry out research at nanometer level
2009-05-28

The Department of Physics at the University of the Free State (UFS) has just received equipment to the value of R23 million that will be utilised for research at nanometer level.

By purchasing the NanoSAM and VersaProbe XPS systems, the UFS also became the only university in Africa that has both these instruments at its disposal.

This also places the UFS at the forefront of surface characterisation at nanometer scale.

Prof. Hendrik Swart, Head of the UFS’s Department of Physics, described the acquisition of this research apparatus as an amazing event for the department. Prof. Swart said this meant that the department would now become a national facility for research on surface characterisation, and that this would also help to ensure that the department’s publication contributions would be included in higher-impact publications.

According to Prof. Swart, this apparatus would not only be valuable for fundamental research on nanophosphors and segregation, but in particular would also assist in the industrial development of better catalysts to synthesise petrol and chemicals from gas or coal supplies. Prof. Swart continued to say that Sasol was one of the industries that would benefit from this, and that Prof. Jannie Swarts from Chemistry was closely involved in the latter.

The equipment was purchased with funds donated by the Faculty of Natural and Agricultural Sciences, the University, the National Research Council and Sasol. Technicians from the manufacturing company are currently visiting the department to assist with the installation and to train staff.
