  • Nanodiamond powders are nanomaterials with unique physical and chemical properties What is vanadium hydride?The vanadium hydride materials V(IV)-100 and V(IV)-25C-H2 were tested for room temperature hydrogen storage to compare their activity to V(III) alkyl hydride gels previously synthesized by our group. 9c Hydrogen PCT adsorption-desorption isotherms were thus recorded at 298 K and compared to standard isotherm of AX-21 recorded under the same conditions at 2-3 mmol total adsorption of H2 for accuracy. The initial material V(IV)-100 reached a maximum of 2.1 wt % at 130 bar Using amorphous boron powder and aluminum powder as raw materials, powder metallurgy is used to prepare AlB12 powder. X-ray diffractometer and scanning electron microscope were used to determine the product's phase composition, relative content, and microscopic morphology, the influence of powder embedding on the phase composition of the product was studied, and the optimal process parameters of the synthesis process were determined. The results show that the Al content of the buried powder dete What is aluminum boride?The structure of aluminum boride is similar to that of intermetallic compounds, and its structure mainly depends on the crystal structure of aluminum metal and boron rather than their valence relationship. Aluminum borides are AlB2, AlB4, and AlB12. The diboride AlB2 can be formed by reacting two elemental substances above 600°C. It is a layered structure in which Al atoms directly overlap (A, A mode), and B atoms are filled in the triangular column formed by the direct o What is Silicon nitride?The basis of silicon nitride ceramics is silicon extracted from pure quartz sand (SiO2). Silicon nitride is then usually formed through a reaction of pure silicon with nitrogen at around 1,200 °C / 2,192 °F. Ceramic components made of silicon nitride are then produced using liquid-phase sintering from fine Silicon nitride powder, which is mixed with other sintering additives to enable complete compaction.

However, the well-passivated surface with organic ligands prevents the nanoparticles from aggregating. The magnetic iron oxide nanocrystals from NN-Labs take advantage of the strong magnetic properties of iron oxide and incorporate them into nano-scale materials. The iron oxide nanoparticles in powder form demonstrate excellent size distribution characteristics, which allow for the MOSIL (MoSi2) has remarkably high chemical resistance and can be used in most furnace atmospheres. The most favorable conditions for MOSIL (MoSi2) are oxidizing atmospheres such as carbon dioxide, air, and water vapor, but MoSi2 elements also tend to operate well in carburizing, reducing, and neutral atmospheres. Air: At lower temperatures, silicon and molybdenum oxidation on the components' surface occurs at temperatures of around 500°C (930°F). The oxidized product formed is MoO3, which is a What is boron?Boron is a chemical element with the symbol B and atomic number 5. Its crystalline form is a brittle, dark, lustrous metalloid; in its amorphous structure, it is a brown powder. As the lightest element of the boron group, it has three valence electrons for forming covalent bonds, resulting in many compounds such as boric acid, the mineral sodium borate, and the ultra-hard crystals of boron carbide and boron nitride. Boron is synthesized entirely by cosmic ray spallation and superno Boron is a chemical element with the symbol B and atomic number 5.

Collaborative regulation of acoustic transport properties of bismuth-based telluride nanostructured materials

Bi2te3-based alloy hexagonal nanosheets were synthesized by gas induced reduction (GIR) method with independent innovation. It was found that the growth of Bi2Te3-based alloy hexagonal nanosheets was based on a selective adsorption mechanism. It was found for the first time that Cu could effectively prevent the oxidation of Bi2Te3. The theoretical calculation shows that the reason is that Cu doping can improve the stability of the system, and Cu is a substitute for doping rather than intercalati
