Whatsapp security
It is important to be safe when using WhatsApp. Do not leave your phone unattended when you are not close by.

There are 2 billion WhatsApp users in the world, and 1,6 billion WhatsApp users access their accounts on a daily basis.

However, it is important to also be safe when using this popular communication tool.

According to Cobus van Jaarsveld, Assistant Director: Threat Detection, Investigations and Liaison in Protection Services, it does happen that people’s WhatsApp accounts get hacked; this is a serious violation of privacy.

“It means a third party now has unlimited access to your personal chats, information, media – and in some instances, they can also masquerade as you by deleting your chats, replying to your chats, and committing crimes. That’s just the tip of the iceberg of how harmful it can be to get hacked,” says Van Jaarsveld.

He adds: “Hackers can access your WhatsApp data by various means, e.g. via WhatsApp web or registering your number on another device.

The South African Police Service (SAPS) provided the following tips to prevent one’s WhatsApp from getting hacked:

• Log out from all computers that you see in the list under WhatsApp Web. This will stop hackers from further reading your chats. However, this should be done every time you use WhatsApp web.
• Do not leave your phone unattended when you are out.
• Lock all your apps to prevent unknown people from accessing your apps.
• Do not connect your phone to unknown Wi-Fi connections, as hackers can also use the unique MAC address to access all your WhatsApp chats.
• In case your WhatsApp has already been hacked, deactivate your account by emailing support@whatsapp.com. Your account will be automatically deleted if not accessed for 30 days.
• Enable two-step verification under your WhatsApp account settings. This will add an extra layer of security to the app.
• Lock WhatsApp. It is imperative to have the AppLocker that will help you lock your WhatsApp. While WhatsApp does not offer this application per se, you can download it and the app will facilitate the use of your WhatsApp with a password or PIN. This will help to prevent anyone who has access to your phone from accessing your WhatsApp account, since they will require a password to open it.

UFS boasts with most advanced chemical research apparatus in Africa 

The University of the Free State’s (UFS) Department of Chemistry now boasts with some of the most advanced chemical research apparatus in Africa after the latest addition, a nuclear magnetic resonance (NMR) spectrometer, was inaugurated today by the Rector and Vice-Chancellor, Prof Frederick Fourie.  The NMR is used to analyse molecular structures. 

Last month the Department of Chemistry celebrated the installation of the most advanced single crystal X-ray diffractometer in Africa.  The diffractometer provides an indispensable technique to investigate among others the solid state of compounds for medicinal application.

“Three years ago the UFS executive management realised that, if we want to build a university of excellence, we should invest in research.  We started to think strategically about chemistry and decided to bring the apparatus at the Department of Chemistry on a more competitive standard.  Strategic partnerships were therefore secured with companies like Sasol,” said Prof Fourie during the inauguration ceremony.

“The installation of the NMR symbolises the ability of the UFS to turn academic areas around.  I hope that this is the beginning of a decade of excellence for chemistry at the UFS,” said Prof Fourie.

”The catalogue value of the Bruker 600 MHz NMR is approximately R11 million.  With such an advanced apparatus we are now able to train much more post-graduate students,“ said Prof Jannie Swarts, head of the Division Physical Chemistry at the UFS.

”The NMR is the flagship apparatus of the UFS Department of Chemistry that enables chemists to look at compounds more easily at a molecular level.  Research in chemistry is critically dependent on NMR, which is a technique that can determine the composition of reactants and products in complicated chemical reactions, with direct application is most focus areas in chemistry,“ said Prof Swarts.

”Parts of the spectrometer consists of non-commercial items that were specifically designed for the UFS Department of Chemistry to allow the study of unique interactions in e.g. rhodium and platinum compounds,” said Prof Swarts.

According to Prof Swarts the NMR enables chemists to conduct investigations on the following:

To evaluate for example the complex behaviour of DNA in proteins as well as the analysis of illegal drugs sometimes used by athletes. 
It provides an indispensable technique to investigate compounds for medicinal application for example in breast, prostate and related bone cancer identification and therapy, which are currently synthesised in the Department of Chemistry.  
It can also be applied to the area of homogeneous catalysis where new and improved compounds for industrial application are synthesized and characterised, whereby Sasol and even the international petrochemical industry could benefit. This analytical capacity is highly rated, especially in the current climate of increased oil prices.
The NMR can detect and identify small concentrations of impurities in feed streams in the petrochemical industry, e.g. at Sasol and also the international petrochemical industry.  These minute amounts of impurities can result in metal catalyst deactivation or decomposition and can cause million of rands worth in product losses.
It is indispensable for studying the complexity of samples that is non-crystalline. These materials represent the vast majority of chemical compounds such as solvents, gasoline, cooking oil, cleaning agents and colorants as examples. 

According to Prof Swarts the general medical technique of MRI (magnetic resonance imaging) in use at larger hospitals, is based on NMR technology.

”The NMR apparatus enabled the Department of Chemistry to characterise complex molecules that were synthesised for the multi-national company, FARMOFS-PAREXEL, and to negotiate research agreements with overseas universities,” said Prof Swarts.
