Special issue of European Journal of Mineralogy dedicated to Zdeněk Johan (1935-2016)
Special issue of European Journal of Mineralogy dedicated to Dr. Zdeněk Johan (1935-2016), our former close collaborator and friend and a world-famous mineralogist, has just been published. This special issue was co-edited by Vojtěch Ettler and contains 20 excellent papers. (www)
Short course on stable isotopes by Dr. Nikolai Pedentchouk (University of East Anglia) – April 18 and 20, 2017
Dr. Nikolai Pedentchouk from University of East Anglia (UK) gave a short course on Stable Isotopes in Earth Sciences on Tuesday, April 18 and 20, 2017. Lectures were supplemented with practical sessions in our isotope lab. Program included fundamentals of light isotopes and systematics of C, O and H isotopes.
First thallium isotope data from our new Neptune MC ICP MS just published in ES&T
We studied how thallium isotopes can be used for tracing anthropogenic pollution in soils contaminated by emissions from coal-fired power plants. These results are the first published isotope data generated by our brand new MC-ICP-MS lab.

Brand new determination of thermodynamic properties of arsenates
In the footsteps of previous research on zýkaite (Majzlan J., Amoako F.Y., Kindlová H., Drahota P. (2015): Thermodynamic properties of zýkaite, a ferric sulfoarsenate. Applied Geochemistry 61, 294-301, DOI) we published in Hydrometallurgy new thermodynamic data for FeAsO4·0.75H2O: Majzlan J., Dachs E., Benisek A., Drahota P. (2016): Thermodynamic properties of FeAsO4·0.75H2O – a more favorable disposable product of low As solubility. Hydrometallurgy 164, 136-140 (DOI).
Alice Jarošíková won Best Poster Prize at SEGH 2016
Alice Jarošíková, PhD candidate in our research group, won Best Poster Prize at SEGH 2016 meeting in Brussels. She briefly describes her research at the web site of Society for Environmental Geochemistry and Health (www.segh.net).
Mineralogy of smelter- and mining-derived particulates affects contaminant mobility in soils
Mobility of metal(loid)s in soils is strongly affected by their binding to solids. We studied smelter- and mining-derived particulates with high levels of metals and metalloids (As, Sb) and their stability in soils from dry semi-arid and wet subtropical areas in Africa.

New isotope lab is here!
Opening of new isotope lab equipped with a Thermo-Scientific Neptune plus MC-ICP-MS and two mass spectrometer for the analysis of stable isotopes (IRMS MAT 253 a Delta V Advantage) took place in February 10, 2016 after several months of preparations. The equipment purchase was funded by EU projects (Operational Programme Prague – Competitiveness, Project No. CZ.2.16/3.1.00/21516 and OP VaVPi project CZ.1.05/4.1.00/16.0347).
