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.

Minquiz competition presented at the UFS
2009-05-20

 
The Minquiz Regional Competition, sponsored by Mintek and the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS), was presented for the fifteenth time on the Main Campus last week. The aim of the competition is to stimulate Grade 12 learners’ interest in science, technology, engineering and specifically the disciplines Chemistry, Physics, Geology and Mineral technology. The competition comprises a written and oral examination, which is divided into categories, namely gold and platinum. Historically previously disadvantaged schools participated in the gold category, whilst schools that were previously categorised as Model C and private schools, as well as previous gold-category winners participated in the platinum category. The winning school in the oral quiz of the gold category was Le Reng Secondary School at Ladybrand and in the platinum category the Secondary School Sentraal came up trumps. The individual winner in the gold category of the written test was Madimatle Molatseli from Re Reng Secondary School and the platinum category was won by Oscar Nouwens from Harriston Secondary School in Bethlehem. The Free State team for the national quiz also includes Lindiwe Sondach (Commtech Comprehensive, Kagisanong), Nkobo Thabang (Lephola Secondary School, Welkom), Moorosi Motake (Leseding Technical High, Welkom) and Dawie Lotz (Sand du Plessis Secondary School, Bloemfontein). These winners will participate in the national competition presented by Mintek in Johannesburg from 23-24 July 2009. At one of the demonstrations presented by the Department of Chemistry were, from the left: Blener Buitendach, Ph.D. student in Chemistry at the UFS, Tshepo Khomoatsana from HTS Louis Botha in Bloemfontein and Goodwill Nogwanya, also from HTS Louis Botha.
