一般描述

Nanosized aluminum oxide, also called nano alumina or Al2O3 nanoparticles, is a form of aluminum oxide with a small particle size and high specific surface area. Our aluminum oxide nanoparticles have a particle size less than 50 nm. The nanoparticles are suspended in isopropyl alcohol (IPA) to facilitate its dispersion and use. Nano alumina exhibits unique bio-physicochemical properties, including high surface area, high hardness, thermal stability, and biocompatibility. In the field of catalysis, it servesas efficient catalyst supports, enhancing reaction rates and selectivity. They also exhibit remarkable dielectric properties, making them valuable for electronic and optoelectronic devices. Additionally, Al2O3 NPs have demonstrated promising results in biomedical applications, including drug delivery systems, biomedical imaging, biosensing, and tissue engineering. They are also key components in advanced coatings, energy storage systems, environmental remediation, optoelectronics, photonics, and personal care products.

A simple one-step and gram-scale synthesis of [Au5Mes5] from AuCl3 was developed, and this molecular precursor was used to generate Au nanoparticles on SiO2 and Al2O3. While [Au5Mes5] does not react with surface silanols and is only physisorbed, its incipient

Solution dispersions of two-dimensional (2D) black phosphorus (BP)--often referred to as phosphorene--are achieved by solvent exfoliation. These pristine, electronic-grade BP dispersions are produced with anhydrous organic solvents in a sealed-tip ultrasonication system, which circumvents BP degradation that would otherwise occur

We demonstrated a promising route for enhancing temperature sensitivity, improving saturation voltage, and reducing power consumption of the MOS(p) tunneling temperature sensors by introducing ultrathin Al2O3 into the dielectric stacks. Detailed illustrations of the working mechanism and device concept are
