Florian Kraus

Studied chemistry at the universities of Regensburg, Germany, and San Diego, USA, and finished in 2003 with a diploma thesis with Prof. Korber on the 6-aromatic P42- anion. In 2005 he finished his Ph.D. Thesis with Prof. Dr. Korber and Prof. Dr. Albert on the reactions of polyphosphides and hydro-closo-borates in liquid ammonia. From 2006 to 2008 he worked as a research assistant with Prof. Dr. Fässler at the Technische Universität München. Starting his own research in the field of inorganic fluorine chemistry in 2006 at the TUM, he obtained the venia legendi in 2011. In 2014 he moved to Philipps-Universität Marburg as a full professor of inorganic chemistry.

Kraus focuses on inorganic solid state fluorine chemistry and uranium chemistry. His current research interests are in basic science: chemistry of the halogenfluorides XF3, and XF5(X = Cl, Br); Mn(IV)-based fluoride phosphors such as K2SiF6:Mn; chemistry with fluorine plasma and the metal hexafluorides MF6; dry chemistry recycling of platinum and coinage metal compounds; chemistry of thorium and uranium; chemistry in water-like solvents such as NH3, BrF3, HCN, HF, and SO2.

Thomas Braun

Studied chemistry at the Julius-Maximilians-Universität Würzburg and received his Ph.D. under the supervision of Helmut Werner. After a short stay with Pierre Dixneuf (Rennes) and postdoctoral work with Robin Perutz (York), he obtained his habilitation at the University of Bielefeld (mentor: Peter Jutzi). In 2007, he was appointed Professor of Inorganic Chemistry at the Humboldt-Universität zu Berlin, where he is full professor since 2011. Thomas Braun received the Wöhler Award for Young Scientists in 2006, the RSC Fluorine Chemistry Prize in 2007, and the Fluorine Publication prize of the Fluorine Subject Group of the German Chemical Society in 2015. From 2010 to 2012 he served as the chair of the GDCh Fluorine Chemistry division and was from 2009 to 2018 vice-chair of the DFG (German Research Foundation) Research Training Group GRK 1582 “Fluorine as the Key Element”.

Currently he is vice-speaker of the DFG Collaborative Research Center “Fluorospecific Interactions: Fundamentals and Applications”, and is also Executive Committee Member of the Fluorine Division of the ACS. The major interests of Thomas Braun are in fluorine chemistry as well as organometallic and coordination chemistry with an emphasis on the catalytic activation of small molecules. This involves C−F and C−H bond activation reactions, but also the chemistry of sulfur fluorides. He also has an interest in heterogeneous catalysis.

Litha Yapi

Litha Yapi is a Chemical Engineer and PhD graduate from the University of Pretoria, with a specialization in the preparation of alumina-supported cobalt trifluoride. He is currently a third-year Chemical Engineering lecturer at the University of Pretoria, where he teaches Separation Process Engineering and Laboratory Practice.

Dr. Yapi’s research focuses on the design and synthesis of fluoromaterials. His work on alumina-supported cobalt trifluoride has been published in peer-reviewed journals, and he has presented his findings at national conferences. Dr. Yapi’s research interests also include energetic materials, green chemistry, and metal-organic frameworks.

Dr. Yapi is a member of professional organizations, including the Engineering Council of South Africa. He is also an active participant in outreach programs aimed at promoting STEM education and careers among underrepresented groups. In his spare time, Dr. Yapi enjoys cycling and exploring the natural beauty of South Africa.

Philip Crouse

Is an industrial chemist and technology developer. He has worked across disciplines for four decades, predominantly in a uranium-, fluorine-, and a general materials- and nuclear environment. He studied chemistry at the University of Cape Town, and was awarded a PhD in 1989 for research done at the Atomic Energy Corporation of South Africa (now Necsa) with respect to fluorine-related corrosion problems in the enrichment plant, under supervision of the late CM Stander. He completed a post-doctoral period at the Technical University of Munchen, Garching, in 1990, familiarising himself with aspects of plasma technology. He was the SARChI incumbent for the Chair for Fluoro-materials Science and Process Integration at the University of Pretoria, Department of Chemical Engineering, during the period 2008‒2020, subsequent to a period at UMIST/UMAN in Manchester, UK. He is currently active in plasma pyrolysis, nuclear hydrogen, and fluorine- and halide-related vapour-phase metallurgy.

Gerard Puts

Studied chemical engineering at the University of Pretoria and obtained his PhD in 2018 under the supervision of Philip Crouse. He spent some time in France at the research group of Bruno Ameduri before joining the pharmaceutical industry as an analytical and process validation specialist. He subsequently joined Metal Refining Engineers in 2023 as the resident expert in process analytical chemistry and is currently working on various fluoride related hydrometallurgy processes.

Josua Oosthuizen

Studied Industrial Engineering at the University of Pretoria and graduated with the Bachelors of Engineering in 2007, obtained his MBA in 2013, and his PMP Certification in 2018. Josua spent 15 years in a project engineering and project management roll in the Mining industry at both Metso and DRA before founding Metal Refining Engineers in order to provide specialised, first principle fluorochemical and chlorochemical engineering services to the global engineering market.
