financial savvy
Over 60% of South African students are in debt and spend more than the average South African adult.

For many students, university is their first money-management experience, and it is therefore crucial for them to prioritise basic personal-finance knowledge in order to avoid poor money management, and not knowing where their money is going.

Various other educational institutions, facilities, and initiatives such as Student Connections highlight student financial wellness as a topic of importance at higher-education institutions, because of the following reasons:

1. Low retention rates (university dropouts)
2. Loan default (graduating with student-loan debt)
3. Financial hardships affecting future success (low academic performance)

According to LinkedIn, a business and employment-oriented service, the spending and saving habits you develop in college are likely to stick with you throughout your adult life.

A personal finance study conducted by University of the Free State (UFS) Economics and Finance Lecturer, Cecile Duvenhage, revealed trends on how much students spend, and what they spend it on. Her outcomes discovered that students believe money buys them worthwhile experiences; it also revealed that over 60% of South African students are in debt, spending more than the average South African. 


According to Duvenhage, the best way to optimise your use of money is to understand three things:

1. The psychology of money – relationship with money, your goals (reality, beliefs, perception, experiences, repeated messages)

2. The science of money – where is your money? What are you using it on, and how to make more (investing, savings, assets, liabilities, expenses, and income/pocket money)

3. The art of money – creating a financial game plan to stay afloat (knowledge, context, personal goals, game plan)

The Guardian website also highlights important tips for managing your money:

- If you’re struggling to manage your personal finances, ask for help. The earlier you get support, the less susceptible you are to overspend 

- If you have financial aid, be sure to complete and send back your signed agreements in order to avoid delays in obtaining your money

- Add up your income, and then deduct all your essential expenses.

- Essential expenses include: tuition fees, rent/accommodation, electricity, and other accommodation expenses, groceries/food, and travel costs

The article, 6 common money management mistakes college students make, advises students to “live within your means, and [to] make choices based on the money that you have available.” 

The article further recommends that students download a free, easy-to-use budgeting app such as Fudget: Budget Planner or Intuit Mint on their cellphones, which automatically creates a basic spending plan to personalise according to their means.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
