Designing and synthesizing a highly active single atom catalyst, especially monodispersed noble-metal atoms fixed in two-dimensional layered double hydroxide (LDH) nanostructures, is crucial accelerating the slow oxygen evolution reaction (OER). Here, Ru (SAs) are stabilized on NiFe LDH (SARu/NiFe LDH) via an oxygen-coordinated bond after facile solution reduction procedure. The OER activity evaluation at similar mass loading glassy carbon reveals that SARu/NiFe shows more than pure basic...
The Henan section of the middle and lower Yellow River (HMLYR) is a crucial economic zone ecological barrier in Central Plains. Rapid urbanization these areas has greatly exacerbated land use change (LUC), which now seriously threatening ecosystem. However, existing research lacks any spatio-temporal analyses method LUC impact on ecosystem service value (ESV), not conducive to precise regulation sustainable development resources. We attempted make up for this shortcoming by superimposing ESV...
Improving the intrinsic catalytic activity of NiFe layered double hydroxide (LDH), which is a benchmark electrocatalyst for oxygen evolution reaction (OER), significant challenge. In present study, we doped ruthenium ions into LDH (Ru-NiFe LDH) to accelerate OER kinetics. Electrochemical measurements and Ru-NiFe at similar mass loadings showed that demonstrated higher than LDH. only requires an overpotential 246 mV 10 mA cm −2 in alkaline media. This attributes doping primarily, can promote...
Land use simulations are critical in predicting the impact of land change (LUC) on Earth. Various assumptions and policies influence structure a key factor decisions made by policymakers. Meanwhile, spatial autocorrelation effect between types has rarely been considered existing simulation models, accuracy needs to be further improved. Thus, this study, driving mechanisms LUC analyzed. The quantity demand distribution predicted under natural development (ND), economic (ED), ecological...
High-speed electrical switching of Ge2Sb2Te5 (GST) remains a challenging task due to the large impedance mismatch between low-conductivity amorphous state and high-conductivity crystalline state. In this letter, we demonstrate an effective doping scheme using nickel reduce resistivity contrast states by nearly three orders magnitude. Most importantly, our results show that produces desired performance without adversely affecting film's optical properties. The level is approximately 2%...
Transition metal Hf doping in NiFe LDHs alters the chemical environment of Ni and Fe, enhancing electronic synergy among three metals. In an alkaline environment, prepared NiFeHf LDH electrodes display a low OER overpotential 177 mV at 10 mA cm-2, demonstrating superior activity.
A reasonable layout optimization strategy of rural residential areas can improve the quality life residents and promote revitalization. Evaluating suitability is basis optimization. Based on 1:100,000 land cover data a digital elevation model (30 m) for Henan Province, China, we used minimum cumulative resistance to evaluate spatial distribution settlements in Zhengzhou administrative area (abbreviated: Zhengzhou). Then, weighted Voronoi diagram determine scope influence central villages...
The large impedance mismatch between the highly resistive amorphous state and conductive crystalline of Ge2Sb2Te5 is an impediment for realization high-speed electrically switched optical devices. In this paper, we demonstrate that tungsten doping can reduce resistivity contrast also results in a lower resistivity. Additionally, it lowers contact resistance, improves contrast, extends face-centered-cubic up to 350 °C, with minimal impact on thermal conductivity.
Developing non-noble metal-based core-shell heterojunction electrocatalysts with high catalytic activity and long-lasting stability is crucial for the oxygen evolution reaction (OER).

Performance testing shows that possesses highest performance...
In order to obtain a material with high solar modulation ability [Formula: see text] and crystalline quality, films were prepared on quartz glass substrates using RF magnetron sputtering under various oxygen partial pressures. Their phase, surface, transmittance, film sheet resistance properties analyzed. As the pressure increased, luminous transmittance of increased as 55.6%, while first maximum 10.8% then decreased. This paper is meaningful aid in application smart windows.
Vanadium dioxide (VO<sub>2</sub>) is a polycrystalline material that exhibits reversible transition from monoclinic semiconducting phase to tetragonal metallic at 68°C. During this transition, both the real part and imaginary of refractive index undergoes dramatic change. Furthermore, finite conductivity VO<sub>2</sub> in phases allows for ohmic heating as source temperature change, which circumvents need an external heat source. This provide attractive means designing switchable optical...
Pixelated wiregrids are of great interest in polarimetric imagers, but there no straightforward methods available for combining the uniform exposures laser interference with a masking system to achieve pixels at different rotational angles. In this work we demonstrate 266nm deep-UV lithography combined traditional i-line contact create such pixels. Aluminum first made, following by etching pixels, and then planarizing molybdenum film is used before patterning subsequent pixel arrays. The...
