In thermonuclear fusion devices retention of radioactive tritium on plasma facing components (PFC) is a major issue from the point of view of safety. Tritium can be trapped in the vessel by co-deposition of plasma fuel with eroded wall material or by implantation,...

Several brominated flame retardants (BFRs) have been found to have adverse effect on human health and the environment and classified as persistent organic pollutants (POPs). Mechanochemical destruction is a promising technology for the safe disposal of POPs because it...

Using 15N stable isotope as a tracer to quantify N transformation rates in isotope-enrichment experiments improves understanding of the N cycle in various ecosystems. However, measuring 15N-nitrate (15NO3–) in small volumes of water for these experiments is a major...

It is planned to breed the reaction in future fusion reactors with lithium from solid lithium ceramics from the eutectic liquid-metal lithium-lead (LiPb). The breeder will be in direct contact with the reduced activation ferritic-martensitic (RAFM) structural steel...

Cathodic arc plasmas are frequently applied to deposit wear-resistant coatings like Al-Cr-N and Al-Cr-O. The metals are introduced as cathodes which are eroded due to the interaction with the plasma. Placing substrates in the plasma stream, metal ions and atoms can...

The importance of investigating the acidity of heterogeneous catalysts cannot be overstated, particularly when acidity is the key factor ruling the outcome of a reaction. Wrong acidic features can easily lead to undesired products and/or, in the worst cases, to the...
