Chemical vapor depositionSiliconChlorineOxygenThe formation of a solid by the reaction of small gaseous molecules during a CVD or CVT experiment is a highly complicated process. In the case of the combustion of
At the same time, due to the highly customizable chemical ratios of the SexSy solid solutions, designing a suitable body framework with reasonable void space is a very big challenge to enable it to accommodate more active materials and minimize their volume changes. Additionally, by introducing ...
The formation of SO3 bears a solid relationship with the concentration of SO2, whereas the concentration of SO2 is dependent on the sulfur content of the fuel and combustion conditions [35–37]. High sulfur contents cause a high SO2 concentration and therefore high SO3 concentration [38]. Comp...
This tribochemical reaction leading to superlubricity even in a dry environment should impact the solid lubricant field in developing long-lasting solid lubricants. Results Friction and wear studies Figure 1 demonstrates the tribosystem tested including the initial configuration (Fig. 1a) and highlights ...
The time scales and formation mechanisms of tri-hydrogen cation products in organic molecule ionization processes are poorly understood, despite their cardinal role in the chemistry of the interstellar medium and in other chemical systems. Using an ultrafast extreme-ultraviolet pump and time-resolved nea...

Iron-mediated methodology for the formation of carbon-carbon and carbon-heteroatom sp(3) bonds on solid phase has been developed. Treatment of a polymer-bound cationic iron cyclohexadienyl complex with carbon, oxygen, nitrogen, and phosphorus nucleophiles, followed by cleavage with amines and subsequ...
(1). The partition coefficients, liquidus temperature, and diffusion coefficients were calculated at each solidification step based on a thermodynamic equilibrium, while they were assumed to be constants with the increase of the solid fraction by Δf s . The thermodynamic equilibrium was calculated ...
Soil formation refers to the dynamic process of transforming parent materials, such as rocks and sediments, into soil through physical and chemical weathering under changing environmental conditions. AI generated definition based on: Encyclopedia of Soils in the Environment (Second Edition), 2023 About ...
Since it is due largely to the loss of chemical bonding, the formation energy is high in strongly bonded solids. It is in fact known to be about 1/3 of the cohesive energy of the solid. The formation volume Δvf of a vacancy is one atomic volume if no relaxation occurs, but in ...
