Disinfectant, soap or probiotic cleaning?
A study about disinfectant, soap and probiotic cleaning extended probiotic cleaning research to a built environment. Through an eight-month cleaning trial researchers compared the effect of three cleaning products (disinfectant, plain soap...
X-ray micro-tomography used to study respiratory anatomy in live larvae
How respiratory structures vary with, or are constrained by, an animal's environment is of great importance to see the differences in evolutionary development and for comparative physiology hypotheses. It is challenging to investigate the...
Oil penetration into vetkoek analysed at Fluorescence Microscopy
The first study using confocal micrographs on the quantitative analysis of vetkoek or magwinya crumb and crust properties was done by scientists from the University of Venda at the CAF Fluorescence Microscopy facility. The confocal laser...
Meet the Teaching Excellence Award winner: Dr Martin Venter
For Dr Martin Venter, one of the recipients of Stellenbosch University (SU) Teaching Excellence Awards 2020–2021, teaching is a tough but rewarding profession. This senior lecturer at the department of Mechanical and Mechatronic Engineering...
Exciting capabilities of X-ray tomography at CT Scanner highlighted in Nature Reviews
X-ray computed tomography (CT) can reveal the internal details of objects in three dimensions non-destructively. This non-destructive imaging modality is well known in its medical form, but it is also very useful for imaging materials and...
Women not safe in their own homes
The annual 16 Days of Activism for No Violence Against Women and Children campaign ends on Sunday 10 December. In an opinion piece for News24, Prof Juliana Claassens (Department of Old Testament and New Testament) writes that we sometimes...
BIOGRIP Node for Soil and Water Analysis fully operational
The BIOGRIP Node for Soil and Water Analysis at Stellenbosch University is now fully operational. The node focuses on enabling the interdisciplinary study of the chemical, physical, geological and biological processes that influence the...
The world according to electrons - an overview of what can be achieved through Scanning Electron Microscopy
Scanning Electron Microscopy (SEM) is a powerful tool for topological, morphological and chemical analysis of a broad range of samples. Few analytical instruments rival the breadth of application in the study of solid-state materials...
Scanning Electron Microscopy - applications in Chemistry and Material Science
Scanning Electron Microscopy (SEM) is a powerful tool for topological, morphological, and chemical analysis of a broad range of samples. Applications in chemistry and material science are looked at more closely in this article. Figure 1...
Scanning Electron Microscopy applications in Earth Sciences
Many geological samples contain a variety of phases. Some of these phases are not easily distinguishable using a backscattering electron detector (BSD). In this case, Energy Dispersive X-ray analysis (EDX) and/or Wave dispersive analysis...
