High-pressure phase transition and amorphization of BaVO.

The structural evolution of metavanadate compounds under high pressure offers valuable insights into phase transitions and changes in material properties. This study explores the structural behavior of BaVO under pressures up to 12 GPa using powder X-ray diffraction and density-functional theory (DFT) simulations. The results indicate a phase transition from the ambient pressure orthorhombic phase (space group 222) to a monoclinic phase (space group 2) at 4 GPa, likely driven by the distortion of the vanadium oxide polyhedron.

Detecting Sensitive Spectral Bands and Vegetation Indices for Potato Yield Using Handheld Spectroradiometer Data.

Remote sensing is a valuable tool in precision agriculture due to its spatial and temporal coverage, non-destructive method of data collection, and cost-effectiveness. In this study, we measured the canopy reflectance of potato ( L.) crops on a plant-by-plant basis with a handheld spectrometer instrument.

Nitric oxide synthase system in the brain development of neonatal hypothyroid rats.

Thyroid hormones play an important morphogenetic role during the fetal and neonatal periods and regulate numerous metabolic processes. In the central nervous system, they control myelination and overall brain development, regional gene expression, and regulation of oxygen consumption. Their deficiency in the fetal and neonatal periods causes severe mental retardation, due to lack of thyroid function, or to iodine deficiency.
