Application
Aluminumoxide is used in composite materials, such as those combining covalent organicframeworks (COFs) with alumina, which serve as efficient separators inlithium-sulfur batteries.
General description
Aluminum oxide, or alumina, is renowned for its hardness, chemical stability, and corrosion resistance. It is extensively used in ceramics and refractories for high-temperature applications, as well as in abrasives like grinding wheels and sandpaper due to its hardness. Additionally, aluminum oxide serves as an electrical insulator in electronic components and as a catalyst support in petrochemical processes. Its biocompatibility makes it suitable for biomedical applications, and it is also utilized in protective coatings to enhance surface durability and wear resistance.
We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Aluminum oxide serves as a multifunctional additive or coating in lithium-ion batteries, helping stabilize electrode–electrolyte interfaces, suppress side reactions, improve thermal stability, and extend cycle life. By enabling safer, longer-lasting cells, it reduces material waste and energy use across the battery lifecycle. Click here for more information.

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

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

Porous aluminum oxide (PAO) is a ceramic formed by an anodization process of pure aluminum that enables the controllable assembly of exceptionally dense and regular nanopores in a planar membrane. As a consequence, PAO has a high porosity, nanopores with

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 have investigated the oxidation of inorganic As(III) with H2O2 catalysed by Al2O3, using X-ray absorption near-edge structure and extended X-ray absorption fine structure spectroscopy. The effects of different reaction conditions (pH, time and initial H2O2 concentration) were also studied
