Prof Richard Ocaya from the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) Qwaqwa  Campus has achieved a significant milestone with a newly patented invention. This patent, developed in collaboration with researchers from Turkey and Saudi Arabia, is the result of work that began in 2017, focusing on a special material known as graphitic carbon nitride.

This breakthrough in temperature measurement technology aligns perfectly with the university's Vision 130 commitment to innovation and addressing global challenges. The new device offers a unique solution to a longstanding issue in the field, providing accurate temperature measurements across an extremely wide range. Existing solutions often require multiple devices, leading to increased costs and reduced accuracy, but this invention simplifies the process.

The device, based on a combination of graphitic carbon nitride and silicon, can measure temperatures from -250°C to 250°C with exceptional consistency and linearity. This range and accuracy set it apart from current technologies, making it suitable for various applications, from standard temperature measurement to specialized settings involving extreme temperatures. It could be especially valuable in deep-space exploration, where equipment faces drastic temperature fluctuations.

The patent underscores the university's commitment to fostering collaborative research, a key aspect of Vision 130. Prof Ocaya attributes the success of the invention to the robust nature of the team, established in 2015. The team is now seeking to commercialize the technology by licensing it to a suitable partner, with organizations like NASA expected to show significant interest.

Prof Ocaya advises other academics considering patenting their inventions to ensure the patent solves a real problem uniquely and is based on sound principles. This makes the invention reproducible and protects it from being copied, assigning exclusive rights to the patent holder. Patenting allows for either manufacturing the devices or licensing them to third parties for royalties and profit. He notes that the main consideration is that the innovation must be practical and solve a specific problem in a novel and commercially viable way. He also acknowledges the challenge many academics face, as the "publish or perish" mentality often leads to choosing scientific articles over patents.

Despite securing the patent, Prof Ocaya and his team continue their research efforts, exploring new possibilities while balancing practical research with academic pursuits. He believes the invention will significantly impact the field of temperature measurement, being integrated into many new designs requiring such measurements.

The university proudly supports this innovative research and anticipates its real-world impact, furthering Vision 130's commitment to increasing UFS's research capacity and capability.

UV Voices Kamerkoor by die KKNK

Membra Jesu nostri – Buxtehude (1637 – 1707)
 

Membra Jesu nostri patientis sanctissima (Die allerheilige liggaam van die lydende Jesus aan die kruis) deur Buxtehude het die Kruisiging van Jesus as tema.

Die uurlange werk word in Latyn gesing en handel in elk van die sewe dele oor ‘n deel van Jesus se liggaam aan die kruis: voete, knië, hande, die sy, bolyf, hart en gesig. Voices Inc – Kovsie kamerkoor word bygestaan deur die Odeion Strykkwartet met Francois Henkins, Abrie de Wet, John Wille en Michaela Haller. Die kontrabas word deur Alba Henkins-Molller bespeel en Jan Beukes is die orrelis.

Die woorde in Latyn wat buitengewoon was vir ‘n werk deur Buxtehude, is geneem uit die Latynse Bybel (Vulgate) en van die Rhytmica Oratio Sancti Bernadi, ‘n strofiese gedig deur St Bernard van Claivaux (c1090 – 1153).

Die wyse waarop Jesus se pyn aan die kruis uitgebeeld word asook die gebed en uitroep van versoening tussen God en die mensdom was deel van die Piëtiste se oortuigings van die tyd.

Die werk is saamgestel uit sewe afsonderlike dele wat telkens deur ‘n instrumentale sonate aangekondig word. Die koor lui die vokale bydrae in en sluit elke deel ook af. Die res van die werk bestaan uit verskillende groeperings van solo’s en trio’. Interessante vokale kombinasies kan gehoor word, bv. twee soprane en bas asook sopraan, alt en tenoor.

Hierdie opwindende aanbieding van Membra Jesu nostri, ‘n juweel uit die Baroktydperk, word aangebied deur ‘n groep energieke studente van Kovsies. Die jeugdige klank van die soliste – almal studente aan die Universiteit van die Vrystaat - dra by tot die egtheid van die Barok-klank. Die koor staan onder leiding van Leona Geldenhuys, dosent in Koorleiding aan die UV.

Optreedatums in die Moederkerk op Oudtshoorn. is:

 

  • Vrydag 25 Maart om 19:00
