Allotrope of HfO2 is explored by using first-principles evolutionary algorithm technique, based on density functional theory. The tetragonal structure with the space group P4/nmm demonstrated thermodynamically stable within harmonic level. Arising particularly from relative enthalpy, hafnium dioxide allotrope taken into account in appraising dynamic stability. Following this, phonon calculation...

Weather forecasting is based on the use of numerical weather prediction (NWP) models that are able to perform the necessary calculations that describe/predict the major atmospheric processes. One common problem in weather forecasting derives from the uncertainty related to the chaotic behaviour of the atmosphere. A solution to that problem is to perform in addition to “deterministic” forecasts,...

New BaMnPnF (Pn = As, Sb, Bi) are synthesized by stoichiometric reaction of elements with BaF₂. They crystallize in the P4/nmm space group, with the ZrCuSiAs-type structure, as indicated by X-ray crystallography. Electrical resistivity results indicate that Pn = As, Sb, and Bi are semiconductors with band gaps of 0.73 eV, 0.48 eV and 0.003 eV (extrinsic value), respectively. Powder neutron diff...

MicroRNAs (miRNAs) have been considered to be potent biomarkers for early disease diagnosis and for cancer therapy. The rapid and selective detection of miRNAs without reverse transcription and labelling is highly desired. Herein, we report a simple and label-free miRNA detection method that is based on the Duplex-Specific Nuclease (DSN)-Assisted simple target miRNA recycling procedure. The int...

β-UPSe was synthesized from the reaction of U(2)Se(3), P and Se in a CsCl flux in a fused-silica tube. It crystallizes with four formula units in the tetra-gonal space group I4/mmm in the UGeTe structure type. The asymmetric unit comprises one U (site symmetry 4mm), one Se (4mm), and one P (mmm.) atom. The U atom is coordinated in a monocapped square-anti-prismatic arrangement, where the square...

The phase stability of the hafnium dioxide compounds HfO2, a novel material with wide range application due to its versatility and biocompatibility, is predicted be achievable by using evolutionary technique, based on first-principles calculations. Herein, candidate structure HfO2 revealed adopt tetragonal under high-pressure P4/nmm space group. This evidently confirms structures, since decompo...

We report high-pressure structural studies (52 GPa) at room temperature combined with magnetic [(M(T):1GPa] and electrical resistivity [(ρ(T):0-21GPa)] measurements down to 2 K on Fe0.99Ni0.01Se0.5Te0.5 superconductor using designer diamond anvils (D-DAC) pressure cell. The M(T) data show huge enhancement of superconducting transition (Tc) from 8.62 14.8 (1 ρ(T) reveal maximum Tc ~ 30.5 3 GPa (...

The rising cost of cement and the problem waste disposal with regard to coconut rice husks lead research on a clay brick good physical properties that can replace at same time keep our environment clean. In line this, bricks were moulded clay, cement, husk ash, ash. analyzed determine their properties. this study, set tables for mixing proportion raw material in grams 33.3 cm3 water, table invo...
