In the present study the corrosion behaviour of a β CuAlBe shape memory alloy containing stress-induced martensite in a 3.5% NaCl solution adjusted to pH 8 was analyzed, in view of its application as seismic dampers in bridges. This condition is intended to be a simple approximation for a sea water environment. The element distribution maps of samples were obtained using ToF-SIMS analysis while EBSD &...Read More
In this application example, we show how the TESCAN Xe plasma FIB is suitable to performing large-volume FIB-SEM tomography of biological specimens offering higher resolution compared to conventional techniques such as CT, allowing the visualization and identification of specific features, organs and micro- and nanostructures. In particular, we demonstrate the viability of this technique by presenting a FIB-SEM tomography of a Zebrafish...Read More
The virtual SIMS laboratory at the University of the Witwatersrand provides access to the 1280-HR, housed at the Helmholtz GeoForschungsZentrum Potsdam (GFZ), in Germany via an internet link.
Ion microprobes, also known as secondary ion mass spectrometers, use a finely focused ion beam to sputter the surface of a solid sample. A small percentage of the material liberated from the polished surface of the sample is ionised, and these secondary ions are acc...Read More

With your success utmost in our minds, we have developed the XtaLAB Synergy-S X-ray diffractometer for single crystal X-ray diffraction. Using a combination of leading edge components and user-inspired software tied together through a highly parallelized architecture, the XtaLAB Synergy-S produces fast, precise data in an intelligent fashion.
The system is based around the PhotonJet-S series of microfocus X-ray sources that i...Read More
Wirsam scientific attended the SAIMM geometallurgy conference from the 6th to the 8th of August 2018 hosted at the Lagoon Beach Conference Centre, Cape Town. The conference was themed "back to the future" was inspired by looking both into the past and the future: the concept of Geometallurgy goes back to some of the earliest mining activities when mineral recognition, mining, separation and concentration were undertaken simultaneo...Read More
Researchers are interested in the impact of gene expression and protein function not only at the cellular level but also within whole tissues, organs and even organisms. Hence organisms like C elegans, Drosophila, Zebra fish, Xenopus, Mouse or the plant Arabidopsis are used as biological models for in vivo studies in a vast field of research applications. The introduction of the naturally fluorescent protein makers, such as Green Fluorescent Protein (GFP),...Read More
From the 23rd to the 27th of July 2018 XRF users from around South Africa and neighbouring African countries gathered at the Wirsam Scientific head office in Johannesburg for an introductory course in Practical XRF Analysis. The workshop was presented by Dr. Clive Feather (Geological Consultant) and from Wirsam Scientific, Benjamin Marrian, George van der Walt & Alex Wagner.
The course was well attended and delegates had the opportunity to expan...Read More
