Electrochemical assessment of vanadium hydride

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

Physical and chemical properties of aluminum boride

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

A comparative hardness study of AlB2

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

Structural components made of Silicon nitride

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. The compaction and needle-shaped recrystallization of the silicon n

The chemical structure of iron oxide is based on a cubic inverse single group structure

What is Fe3O4?Iron oxide (Fe3O4) powder is the pure powder form of the corresponding nanocrystals without solvents. 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

Chemical Resistance of MoSi2

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

Elemental Boron is a metalloid

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

Zinc sulfide chemical compound

Zinc and cadmium sulfides are the most critical basic materials of sulfide-type phosphors. An essential condition of getting highly efficient phosphors is that these sulfides must first be prepared to the highest possible chemical purity before the necessary amount of activator. Some inorganics, such as silver-activated zinc sulfide, are suitable scintillators but cannot be grown in optical-quality large crystals. As a result, their use is limited to thin polycrystalline layers known as phosphor

Electrochemical Investigation of copper oxide films formed by oxygen plasma treatment

What is copper oxide?Copper and Oxygen, when combined, form magnetic materials, including copper oxide (I) and copper oxide (ll); both minerals are found in nature and have unique characteristics and particular uses. Copper oxide (II), or cupric oxide, exists in nature as a component of minerals such as tenorite, paramelaconite, and extracted minerals worldwide. However, there is a process to produce it industrially. Copper Oxide is insoluble in water and soluble in ammonia solution. It is a com

Excita tion energy to analyze the chemical structure of SnO2 and ATO NPs

Hard X-ray photoelectron spectroscopy (HAXPES) measurements were conducted with two keV excitation energy to analyze the chemical structure of SnO2 and ATO NPs. The survey spectra of the sample series, along with photoemission line identification, the spectra of the ATO series in the Sn 3d and the overlapping Sb 3d/O1s peaks regions. The Sn doublets are centered at binding energies (BEs) of ~ 487.6±0.1 eV for 3d5/2 and ~ 495.9±0.1 eV for 3d3/2, in agreement with literature values for SnO2, while

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
