The upper panel shows a representative voltage profile of the first discharge-charge cycle of Li-O2 cells with ATO cathodes, with marked states of charge (SOC) for the subsequent analysis of discharge products #1, #2, and #3. The lower panel depicts ...…
What is ATO?Antimony-doped tin oxide (ATO) nanoparticles have been proven to exhibit special optical properties and excellent electrical conductivity to be used as thin film electrodes. Studies have shown that antimony-doped tin oxide possesses a hig...…
For the in-situ gas analysis during discharge and charge of the Li-O2 battery with ATO-based cathodes and Vulcan carbon cathodes, a coupled system with a direct pressure/vacuum capacitance manometer (Baratron, MKS instruments, in the following referr...…
The water glass typically used in industry is synthesized using sodium and potassium silicate. In our experiment, as the selective adsorption of the strongly acidic cation exchange resin is greater when the valence of the ion is larger, the water gla...…
Zinc sulfide (ZnS) (3.7 eV band gap) deposited via chemical bath deposition (CBD) has been used previously as a buffer layer material in copper indium gallium selenide (CIGS)-based PVswith reported power conversion efficiency of 16.9%, equaling the p...…
The chemical doping of monolayer MoS2 film over a 13 cm2 area for developing photodetector devices was reported by Kim et al.. The n-type MoS2 semiconductor transitions into the p-type semiconductor after doping with Nb. Raman spectroscopy, X-ray pho...…
As discussed above, the performance of MoS2 photodetectors can be significantly increased by doping MoS2 layers with APTES,180 rhodamines 6G181, and ZnPc182 organic dyes, which efficiently generate charge transfer interfaces between MoS2 and chemical...…
For example, Kang et al. demonstrated that the field-effect mobility increased from 28.75 cm2 V−1 s−1 to 142.2 cm2 V−1 s−1, and the photoresponsivity increased from 219 A W−1 to 5.75 × 103 A W−1 for APTES/MoS2 hybrid phototransistors after aminopropy...…
What is silica?Silicon is one of the most abundant elements in the Earth's crust, the second most abundant after oxygen. Silica is a compound that is important for human Nutrition and health. It is found mainly in bones, nails, hair, and hoof tissue....…
The results show that a coating layer is formed on the surface of boron powder after being coated by the coating agent. The pH value of boron powder and water suspension system increases obviously after coating, which is suitable for the pharmaceutic...…
What is boron powder?Boron powder is a solid black powder. It has a melting point of 2360℃, a boiling point of about 2700℃, a specific gravity of 2.4, and a Mohs hardness of 9.3. It was heated in the air to 900℃ combustion, at 850℃ with molten sodium...…
Zinc sulfide, chemical formula ZnS. The chemical bond property between Zn and S is inclined to covalent bond type. The crystal has three different configurations: low-temperature Type, namely sphalerite structure, which is abundant in nature. Colorle...…
Titanium Aluminum Carbide MAX Phase Micron-Powder. Chemical Name: Titanium Aluminum Carbide. Titanium aluminum carbide belongs to the hexagonal crystal system and: it has the same conductivity or heat conduction as metal but has the same high elastic...…
All known wet chemical methods can synthesize iron oxides, but tailoring the particle size to the nano range and the morphology toward a particular application remains challenging. Iron oxides, either Fe3O4 or γ-Fe2O3, can be prepared from aqueous Fe...…
