A molecular dynamics study is done on cuboid and spherical Fe3O4 magnetic nanoparticles (NPs) to investigate qualitatively the influence of the molecules NH4OH and NaOH on their binding energy.

Mesoporous AlOOH was synthesized by hydrothermal treatment from aluminium nitrate and NaOH or KOH. The effect of NaOH and KOH as precipitating agents on the characterization of samples were...

2020年5月15日 · In this work, we present the high pressure structural behavior of Na 2O by angle-dispersive X-ray diffraction at room temperature up to 30.1 GPa. An amorphous transformation of Na2O has been observed. The bulk modulus of cubic anti-fluorite Na2 O has been investigated by experiments for the first time and compared with previous calculations. 2.

An integrated approach, based on quantitative transmission mode powder X-ray diffraction (PXRD) combined with multivariate statistical analysis, has been applied to cellulose obtained from three different sources to correlate the mercerization ...

According to Joint Committee on Powder Diffraction Standards (JCPDS) standards, its crystal form is confirmed to be halite NaCl by diffraction peaks at 27.4°, 31.7°, 45.4°, 53.7°, 56.4°, 66.2° and...

在这项研究中，使用沉淀技术合成了用于光催化和介电应用的 ZnO 纳米颗粒。研究了 ZnO 纳米颗粒在各种氢氧化钠 （NaOH） 浓度下的性质。采用粉末 X 射线衍射 （PXRD） 方法分析结构特性。PXRD 显示细胞体积从 47.92 Å 减少到 47.73 Å，微晶尺寸从 31.96 到 22.53 nm 变化。

2024年3月1日 · We describe nanocellulose (NC) hydrogels formed from chemically unmodified NC by cellulose crystalline transformation and subsequent freeze cross-linking reaction. The freeze cross-linked NC hydrogel with macropores (~100 μm) was prepared by freezing a mixture of NC and NaOH (0.2 mol L−1), adding citric acid to the frozen mixture, and thawing it.

2025年3月7日 · Powder X-ray diffraction (pXRD) experiments are a cornerstone for materials structure characterization. Despite their widespread application, analyzing pXRD diffractograms still presents a significant challenge to automation and a bottleneck in high-throughput discovery in self-driving labs.

粉末x射线衍射 （pxrd）作为一种非破坏性分析技术，因其高效、准确和灵敏的特点，广泛应用于药物晶型的鉴定和分析。 PXRD通过测量X射线与药物粉末样品之间的衍射模式，能够提供关于晶体结构的详细信息。

2020年11月5日 · NaOH has a modulatory role in promoting the coordination between Cu and GA. As a base, NaOH triggers the deprotonation of carboxylic acid and hydroxyl group of GA, thus produces electron-rich GA.
