Discussing progress in green energy and nuclear medicine during the recent ReMec2, were from the left: Dr Dumisani Kama (UFS), Prof Roger Alberto (University of Zurich), Prof Andreas Roodt (UFS), and Dr Orbett Alexander (UFS).

Scientists in South Africa and Switzerland, with a research collaboration of 20 years, are working together to make a difference. A major focus of their work is nuclear medicine and green energy. 

Since the end of October, 22 speakers from five countries met for five days at four different sites in South Africa to discuss their work during the second symposium on reaction mechanisms, better known as ReMec2. The Department of Chemistry at the University of the Free State (UFS) hosted this event. 

Considerable reduction of carbon dioxide

According to Prof Andreas Roodt, lead researcher from the UFS Department of Chemistry, ReMec2 focused mainly on two projects: nuclear medicine and an R8 million project titled: Solar Light-driven Homogeneous Catalysis for Greener Industrial Processes with H2 (hydrogen gas) as Energy Source and CO2 (carbon dioxide) as C1 Building Block. This is a sunlight-driven project in search of new catalysts, which are chemical compounds that make the reactions faster and more effective, but which are not consumed during the reaction. The aim is to provide greener industrial processes with hydrogen as energy source, and to reduce carbon dioxide in the environment.

This research, if applied, has the probability of preventing the release of more than 100 kg of harmful carbon dioxide for every one kg of hydrogen produced. “Together with the Swiss group, we are at that stage of the research where these compounds, with just one molecule of the catalyst, can make 80 000 hydrogen molecules (very clean energy, as hydrogen in a car's engine burns to clean water; not like gasoline that burns to harmful carbon dioxide),” Prof Roodt explains. 

The UFS and the research group from Prof Robert Alberto at the University of Zurich have been working together on this research for the past twenty years. According to Prof Roodt, they are studying complete reaction mechanisms, including the time profile of how the different chemical compounds are reacting with each other and not just the simple product analysis as studied by most groups in the world. 

International patent on nuclear medicine

In June 2019, they registered an international patent on nuclear medicine model compounds. The patent was granted. During ReMec2, a lecture was presented on this patent, according to which a compound with an imaging isotope [Tc-99m] that has its own ‘X-rays’, can shed light on an affected organ in the human body for doctors to see where medicine should be administered. The same compound also contains the medicine to treat the disease. 

The work of these scientists is 100% in line with South Africa’s National Development Plan and it supports the UFS Strategic Plan. “The programme also builds on students’ research and increases network and collaboration possibilities. We receive more international acknowledgement for our research efforts and compete with the best in the world. Our research is not necessarily about having the best equipment (although it is very important), but critically it is about the generation of innovative ideas,” says Prof Roodt.

UFS staff get salary increase of at least 7,25%

During the signing of the UFS's salary agreement were, from the left: Mr Olehile Moeng (Chairperson of NEHAWU), Prof. Frederick Fourie (Rector and Vice-Chancellor of the UFS), and Prof. Johan Grobbelaar (Chairperson of UVPERSU and spokesperson of the Joint Union Forum).
 

UFS staff get salary increase of at least 7,25%

The University of the Free State’s (UFS) management and trade unions have agreed on an increase of 9,32% in the service benefits of staff for 2008. This includes a general minimum salary increase of 7,25%.

A once-off non-pensionable bonus of R3 000 will be paid in December 2007.

The agreement was signed today by representatives of the UFS management and the trade unions, UVPERSU and NEHAWU.

“As the state subsidy level is unfortunately not yet known, remuneration could vary several percentage points between a window of 7,25 and 8,39%,” said Prof. Frederick Fourie, Rector and Vice-Chancellor of the UFS.

Should the government subsidy be such that the increase falls outside the window of 8,39%, the parties will negotiate again.

The bonus will be paid to staff members who were employed by the UFS on UFS conditions of service on 14 November 2007 and who assumed duties before 1 October 2007.

The bonus is payable in December 2007 in recognition of the role played by staff during the year to promote the UFS as a university of excellence and as confirmation of the role and effectiveness of the remuneration model.

“It is important to note that this bonus can be paid due to the favourable financial outcome of 2007,” said Prof. Fourie.

“Our intention is to pass the maximum benefit possible on to staff without exceeding the limits of financial sustainability of the institution.  For this reason, the negotiating parties reaffirmed their commitment to the Multiple-year Income-related Remuneration Improvement Model used as a framework for negotiations.  The model and its applications are unique and has as a point of departure that the UFS must be and remain financially sustainable,” said Prof. Fourie and Prof. Johan Grobbelaar, Chairperson of UVPERSU and Spokesperson of the Joint Union Forum.

The agreement provides for the phasing in of fringe benefits of contract appointments for 2008.  This includes the implementation of a pension/provident fund, housing allowance and the medical fund allowance as from 1 January 2008 to staff who are appointed on a contract basis.

Agreement was also reached that 1,0% will be allocated for structural adjustments in order to partially address the backlog in respect of remuneration packages of other higher education institutions.  These adjustments will be made after further investigations during 2008. 

The post levels that have been earmarked for adjustment are academic staff (associate professor, professor and dean) as well as certain post levels in the support services.

An additional R500 000 will be allocated to accelerate the rate of phasing in the medical fund allowances. 

The implementation date for the salary adjustments is 1 January 2008, but could possibly be implemented only at a later stage due to logistical reasons.   The adjustment will be calculated on the remuneration package.

The agreement also applies to all staff members of the Vista and Qwaqwa Campuses whose conditions of employment have already been aligned with those of the Main Campus.

Prof. Grobbelaar said that salary negotiations were never easy, but the model is an important tool.  He said the Joint Union Forum illustrates that people from different groups can work together if they share the same commitment and goal.

In 2007, a total salary adjustment of 5,7% and a once-off non-pensionable bonus of R2 000 was paid to staff.
