Luminescence of the CsZrCl under High Pressure.

The photoluminescence (PL) and Raman spectra of the CsZrCl crystal over a wide range of pressures were studied in this work for the first time. PL measurements were performed up to 10 GPa, while the Raman spectra were measured up to 20 GPa. The PL data revealed a linear blue shift of the emission maximum from about 2.

Characterization of vanadium of biological origin for possible applications in physics experiments.

For the first time, vanadium of biological origin, extracted from centrifugal fraction of vanadium-storing blood cells of the Ascidia sydneiensis samea species, was characterized as regards its isotopic composition and content of natural radioactive elements potassium (K), thorium (Th) and uranium (U). The natural abundance of vanadium isotopes has been confirmed with high accuracy, thus excluding a possible selectivity within bio-chemical reactions of vanadium concentration in blood cells from seawater. A large potassium concentration (up to 5500 × 10 g g) was found in the blood cell samples.
