A thermal sensor was used to better understand parameters which influenced the interaction between a laser beam and a 0.5% Mn-doped ZnAlO material, especially the laser defocusing parameter. The optical properties of the material depend on whether the Mn ions occupy octahedral and/or tetrahedral sites depending on thermal history.

Isothermal assays have been proposed for application in field situations as well as low resource settings and hence we developed a reverse-transcriptase recombinase polymerase amplification (RT-RPA) to detect WNV and WSLV known to occur in South Africa, causing sporadic outbreaks usually associated with good rainfall favouring mosquito breeding. Infectious virus can only be handled within a biosafety level (BSL) 3 facility, hence we opted to validate the assay with transcribed RNA.
