Scintillator materials convert high-energy radiation into photons in the ultraviolet to visible light region for detection. In this review, advances X-ray emission dynamics of inorganic scintillators are presented, including halides (alkali-metal halides, alkaline-earth rare-earth oxy-halides, oxyorthosilicates, halide perovskites), oxides (binary oxides, complex post-transition metal oxides), ...

We present results from theoretical studies of aqueous ionic solvation of alkali halides aimed at developing a microscopic description of structure and dynamics at the interface between air and salt solutions. The traditional view has depicted the air/solution interface of simple electrolytes as being devoid of ions. However, it is now firmly established that polarizable anions, such as the hea...

— The concept of local defect pressure is developed and is applied to determine the elastic relaxation about point defects in ionic solids. The method is superior to that of Kanzaki forces for treatment of Coulomb and many-atom interactions. The lattice sums for the Coulomb interaction and the relaxation volume of Schottky defects in NaCl and KC1 in the static limit are given; the use of neutra...

The properties of aqueous ammonium salt solutions at the air/water surface are presented. By comparison of the properties of ammonium halides solutions with those of sodium halide, we note a close similarity, which indicates that the increments in surface tension may be explained in relation to the hydration enthalpy of anions. We find that the behaviors of the salts with nitrate anions which a...

There has been considerable interest in recent years in the use of organic molecules as active electronic and optoelectronic materials for devices. As such, research into the properties and structures of molecular films, crystallites and isolated molecules on surfaces has become an active field, both for the promise of single molecule devices and the prospect of thin film organic electronics. H...

The energy relaxation times of the fundamental stretching modes in the electronic ground state of OH, OD, SH, and TeH in a variety of alkali halides are measured by incoherent laser saturation and found to vary from 0.3 to 3 ns at 1.7 K. These vibrational lifetimes are between 4 and 8 orders of magnitude smaller than those of other heteronuclear diatomics diluted in crystals, including the ioni...

A novel extracellular thermo-alkali-stable laccase from Bacillus tequilensis SN4 (SN4LAC) was purified to homogeneity. The laccase was a monomeric protein of molecular weight 32 KDa. UV-visible spectrum and peptide mass fingerprinting results showed that SN4LAC is a multicopper oxidase. Laccase was active in broad range of phenolic and non-phenolic substrates. Catalytic efficiency (kcat/Km) sho...

This article summarises the principal results of a theory of the growth of alkali metal colloids in irradiated alkali halides. The theory draws upon the analogy with void growth in irradiated metals. The alkali halides are very susceptible to radiation damage in the halogen sub-lattice when exposed to ionising radiation the primary products being F-centres and interstitial halogen atoms (H-cent...
