Influence of applied uniaxial stress upon the ultraviolet absorption bands in KBr and KI
… has been investigated. The imperfections are the interstitial atom, the interstitial ion, and the negative ion vacancy. The interstitial atom, or H center, is a paraelastic defect which assumes a preferential crystal orientation in the field of an external mechanical stress. From the results of …

Role of nitrogen in the structure and properties of proton irradiated 12Cr1MoWV ferritic/martensitic steel for advanced nuclear reactor cores, The
… also provides the relative amount of interstitial N present across the three alloys. Characterization of the alloys shows that N content has a profound effect on the irradiated defect structures. On-zone scanning TEM (STEM) is used to determine that, as N content increases, the average …

Atomistic simulation of defect structure evolution and mechanical properties at long time scales
… a recently developed activation-relaxation based atomistic method to enhance the accuracy of kinetic predictions, and to enable the investigation of dislocation-defect interactions dynamically at long time scales. We took the Autonomous Basin Climbing (ABC) method as a starting point, and …

New high nuclearity carbonyl clusters
… example of Rhodium carbonyl clusters with two interstitial metal atoms. The presence of several hydride atoms, firstly suggested by chemical evidences, has been implemented by ESI-MS and 1H-NMR, as well as new structural characterization of its tetra- and penta-anion. All these species display …

Modeling of Effect of Alloying Elements on Radiation Damage in Metallic Alloys
… focus on the production behaviors of solute interstitials. The production behaviors of solute interstitials include over-production or under-production, compared with their solute concentration in the Fe matrix. The three alloy systems are: (1) a Fe-Cr alloy system; (2) a Fe-Cu alloy system; …
