This article reports finding of a highly oxidised mineral in diamond inclusion derived from mantle transition zone or lower mantle, very reduced areas on our planet. Such oxidised material is likely linked to subduction of carbonates into this region

Thanks to the physical strength of diamonds and their relatively unreactive chemical nature, their mineral inclusions may remain exceptionally preserved from alteration processes and chemical exchanges with surrounding minerals, fluids and/or melts f

Some features of dominant radiation effects in modern ICs of information, information-computing and control systems when exposed to neutrons are analysed. Occurrence of all main dominant radiation effects in ICs is possible under influence of neutron

The goal of qualification or monitoring of electronic device radiation testings is to ensure that devices meet the set of requirements. In some cases, this can be achieved without full characterization of radiation behavior, which leads to significan

The charge order transition of commonly known magnetite has only recently been unraveled. Here, the measurement of the low-temperature high-pressure phase diagram of a related material (Fe4O5) elucidates the interplay of average oxidation state and c
