June 2020

The first Covid-19 restricted PhD viva in our institute on the 29th of June with an external examiner from Brazil Prof. Daniel Borges (UFSC). Congratulations to Abdullah who passed his Viva examination successfully with minor corrections. His thesis is about Organofluorines in the environment using HR-GF-CS-MAS and MP-AES for detection.

 

 

2020 Principal's Excellence Award

The TESLA group have received one of 2020 Principal’s Excellence Awards.
You can find the link to the winners here: There is a pdf result and a video of the virtual award ceremony.

TESLA members got the prize for industry engagement with the oil and gas industry and the winner are: Eva, Martin, Shaun and Daniel

Publications:

 

Lhiam Paton's paper about arsenolipid transport in breastmilk (Transport of arsenolipids to the milk of a nursing mother after consuming salmon fish) done during is Master Thesis stay at the University of Graz is published now in the Journal of Trace Elements in Medicine and Biology.

 

May 2020

Publications:

CRM rapid response approach for the certification of arsenic species and toxic trace elements in baby cereal coarse rice flour certified reference material BARI-1 published now in the journal Analytical and Bioanalytical Chemistry. TELSA was involved in the international effort to produce a certified reference material for arsenic species, total arsenic and cadmium content in record time due to the need to serve the new legislation for inorganic arsenic in baby rice in Canada.

March 2020

Mauana passed her PhD viva successfully at UFSC in Florianopolis, Brazil with the title “Determination of iodine by high-resolution molecular absorption spectrometry – a comparison between promising molecules”. Mauana spent part of her PhD time at TESLA in Aberdeen working on fluorine determination by high-resolution molecular absorption spectrometry.Congratulations.

 

Publications:

Congratulations to Alexa Brand and coworkers for their publication about trace element speciation in fungal cytosols. Congratulations as well as to Linrui Wu her paper about an unusual enzyme invovled in creating fluorinated metabolites (part of her PhD thesis) is now available here.
