Allgemeine Beschreibung

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.

Anwendung

Aluminumoxide is used in composite materials, such as those combining covalent organicframeworks (COFs) with alumina, which serve as efficient separators inlithium-sulfur batteries.

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
