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.

UFS law experts publish unique translation of neglected source of partnership law

The Centre for Business Law at the University of the Free State (UFS) has translated a unique long neglected Roman-Dutch source of the law of partnership law from Latin into English.  This source dates back to 1666. 

The book, called Tractatus de Societate (A Treatise on the Law of Partnership), by Felicius and Boxelius is published as Volume 40 in the research series Mededelings van die Sentrum vir Ondernemingsreg/Transactions of the Centre for Business Law.  It is the first translation of this Roman-Dutch source into English and comprises of a comprehensive discussion of the South African common law of partnerships.  

“Apart from various brief provisions dealing on a peace meal and an ad hoc basis with diverse matters such as insolvency, there is no comprehensive Partnership Act in South Africa.  The law of partnership in South Africa consists of South African common-law, which is mainly derived from Roman-Dutch law,” said Prof Johan Henning, Dean of the Faculty of Law at the UFS.  Prof Henning is also the leading author and initiator of this comprehensive publication.

“Countries such as America, England, Ireland and The Netherlands have drafted or are in the process of establishing new modern partnership laws in line with new international guidelines, practices and commercial usages,” said Prof Henning.

“However, in South Africa the most recent policy document released by the Department of Trade and Industry explicitly excludes partnership law from its present company law reform programme and clearly regards this as an issue for another day,” said Prof Henning.

“Unless there is a political will to allocate the necessary resources to a comprehensive partnership law revision program, it is a practical reality that South Africa will not have a modern Partnership Act in the foreseeable future,” said Prof Henning. 

According to Prof Henning South African courts have been using the Roman-Dutch partnership law sources as authority.  “The English Partnership Act of 1890 is not binding and the English text books should therefore be approached with caution,” said Prof Henning.

“A treatise on the law of partnership that has been regarded by South African courts as an important common law authority is that of  a Frenchman by the name of Pothier.  This treatise was translated into English and was regarded as an au­thority of significance in The Netherlands towards the end of the eighteenth century,” said Prof Henning. 

“Pothier’s opinions are however not valid throughout in the Roman-Dutch partnership law as it did not apply to the Dutch province of The Netherlands and it sometimes also rely on local French customs for authority,” said Prof Henning.

For this reason the Centre for Business Law at the UFS decided to focus its attention again on the significance of the comprehensive treatise of Felicius and Boxelius on the Roman-Dutch partnership law.  Felicius was an Italian lawyer and Boxelius a Dutch lawyer.

This long neglected source of partnership law was published in 1666 in Gorkum in The Netherlands.  "A significant amount of Roman-Dutch sources of authoritive writers trusted this treatise and referred to it,” said Prof Henning.

The translation of the treatise from corrupted medieval lawyer Latin into English  was done by Prof Boelie Wessels, a very well-known expert on Roman Law and senior lecturer at the UFS Faculty of Law.  Prof Wessels, who  has 15 degrees, spent almost ten years translating the treatise.  The proofreading and editing of the translation was done by Prof Henning and Adv Jaco de Bruin, a senior lecturer at the UFS Faculty of Law.

“We want the South African courts to use Volume 40 in the research series Mededelings van die Sentrum vir Ondernemingsreg/Transactions of the Centre for Business Law as the primary source of reference when cases where Roman-Dutch Law partnership law principles are involved, are ruled on,” said Prof Henning.

The first part of the publication comprises of selected perspectives on the historical significance of the work as well as a translation of selected passages. “The intention is to follow this up expeditiously with the publication of a very limited edition of a complete translation of the work,” said Prof Henning.

A total of 400 copies of the publication will be distributed to all courts, the Appeal Court and the Supreme Court.
