In this webinar, Prof Brownhilder Neneh of the University of the Free State, and Christopher Rothmann, co-founder of LiquidCulture, discuss the intersection between the two fields of science and entrepreneurship, and entrepreneurship and the university curriculum from an interdisciplinary perspective. The webinar will provide insight into entrepreneurship at universities, particularly the UFS, advancing entrepreneurship development and entrepreneurship-related programmes that are student focused, and illustrate the critical role that entrepreneurship plays in the lives of students.

This webinar is part of a series of three webinars on Interdisciplinarity that is presented from November to December 2020 via Microsoft Teams for a duration of 45 minutes each. The webinar topics in the series explore the intersection between Neuroscience and Music, between Science and Entrepreneurship, and between Science and Visual Arts.  

Date: Tuesday 24 November 2020
Topic: The intersection between science and entrepreneurship 
Time: 13:00-13:45 (SAST)
RSVP: Alicia Pienaar, pienaaran1@ufs.ac.za by 23 November 2020 
Platform: Microsoft Teams

Introduction and welcome

Prof Corli Witthuhn 
Vice-Rector: Research at the University of the Free State 


Presenters

Prof Brownhilder Neneh 

Prof Neneh is Associate Professor and Academic Chair (HOD) in the Department of Business Management at the University of the Free State.  She is an NRF-rated researcher in the field of entrepreneurship and small business development. Her research is primarily based in the field of entrepreneurship, where she looks at different aspects of a business venture – from business gestation activities to performance, growth, and exit.  She also focuses on some niche areas in entrepreneurship, such as women and student entrepreneurship. She was a 2019 winner of the Emerald Literati Awards in the category Outstanding and Highly Commended papers. 

Christopher Rothmann – Co-founder of LiquidCulture

Liquid Culture (LC) was started by Christopher Rothmann and Dr Errol Cason in the UFS Department of Microbial, Biochemical and Food Biotechnology in 2018. They produce yeast in its purest liquid form. LC is the only company in Africa to do so. Their yeast is mainly used by breweries for the fermentation of beer and they have since also branched out to the baking and distillery industries. Christopher was awarded the joint runner-up position in the Existing Tech Business category of the 2019 Entrepreneurship Intervarsity.

Three heart-valve studies which have been developed at the Robert WM Frater Cardiovascular Research Centre at the School of Medicine at the University of the Free State (UFS) were recently presented in Monte Carlo at the conference of the prestigious global Heart Valve Society (HVS).

These studies are all headed by Prof Francis Smit, Head of the Department of Cardiothoracic Surgery at the UFS, and Manager of the Robert WM Frater Cardiovascular Research Centre.
Prof Smit says the HVS is a combination of the former heart-valve societies of Europe and the US. “Studies on heart-valve disease, heart-valve-related products and operations, as well as the design and development of new valves were presented. There are both clinical and development divisions.

He says the study in which the hemodynamics of their redesigned mechanical poppet valve was compared to a commercial bi-leaflet mechanical heart valve, was named as the best poster presentation in the experimental valve development and numerical flow dynamics division. The study, which was presented by Kyle Davis, mechanical engineer at the centre, competed against some of the best heart-valve research units in the world.

The redesigned valve, based on the 1960s Cape Town poppet valve, has the potential to provide a low-cost solution for mechanical heart-valve replacement. It is possible to produce the titanium ring with 3-D printers and is, together with the silicon poppet valve, extremely inexpensive compared to current mechanical valve-manufacturing processes.
The advantages of this valve over current mechanical valves is that, due to the effective and laminar flow characteristics, as well as the simple locking mechanisms, there is a reduced chance of valve thrombosis, and the need for anti-clotting drugs is therefore limited.

It was also confirmed that the new valve more than meets the published FDA (Federal Drug Agency) requirements, which determine the minimum standards of valves for human use in the US.

The redesigned valve also has a very low platelet activation impact, which is responsible for platelet thrombosis and leads to valve thrombosis or strokes. This valve is another heart-valve project by the centre, which is also in the process of evaluating a tri-leaflet polyurethane valve developed by them.
