The recent discovery of superconductivity in Nd$_{1-x}$Sr$_{x}$NiO$_2$ has drawn significant attention the field. A key open question regards evolution electronic structure with respect to hole doping. Here, we exploit x-ray absorption spectroscopy (XAS) and resonant inelastic scattering (RIXS) probe doping dependent NiO$_2$ planes. Upon doping, a higher energy feature Ni $L_3$ edge XAS develop...

Based on first-principles calculations, an antiferromagnetic Ising model a triangular lattice has been proposed to interpret the order of Fe$(1)$-Ge pairs and formation $\sqrt{3}$ $\times $ superstructures in Fe$_5$GeTe$_2$ (F5GT), as well predict existence similar Ni doped F5GT (Ni-F5GT). Our study suggests that systems may be considered structural realization known lattice. superstructures, H...

The all-d-metal Ni-Mn-Ti Heusler alloy has giant elastocaloric effect and excellent mechanical properties, which is different from the conventional Ni-Mn-based alloys. In this work, preferred site occupation, phase stability, martensitic transformation, magnetic electronic structure of B-doped Ni2Mn1.5Ti0.5 alloys are systematically investigated by first-principles calculations. results show th...

Nanometer TiO2 photocatalysts were prepared by the sol–gel method. The catalysts characterized X-ray diffraction, Fourier-transform infrared spectroscopy, ultraviolet-visible and other techniques. Methyl orange solution was used for degradation of organic material ultrasonic technology to determine photocatalytic performance catalysts. results show that Ni-N-TiO2 is clearly improved under condi...

Hydrogen production via water electrolysis with renewable electricity as input will be crucial for the coming defossilized energy age. Herein, we report an anion exchange membrane electrolyzer using Fe-doped Ni hydroxide anode catalyst that is on par proton electrolyzers in terms of performance, 2 A cm–2 at 2.046 V and 50 °C. We found Fe doping stabilizes ?-Ni(OH)2 phase, which key to ensure fa...

Research, development for finding new targets in tumors, targeting methodsand stabilizing the nano particle in targeted cells is based on drug delivery and its crucialeffect. Examining the computational controlled drug delivery by graphene sheets has becomevery significant due to numerous side ...

In this paper, we describe the creation of a moderate band gap Nd-substituted Ni-Zn ferrite as nano photo catalyst via simple and cost-effective process solution combustion. Nd substitution alters crystallite size, shape, gap, magnetic characteristics significantly. Investigations using X-ray diffraction revealed that all samples display pure phase. The average size was determined to be between...
