The effect of carbon-chain oxygenation in the carbon-carbon dissociation

Journal of Molecular Modeling, 2018
Currently, there is a trend of moving away from the use of fossil fuels to the use of biofuels. This modification changes the molecular structure of gasoline and diesel constituents, which should impact pollutant emissions and engine efficiency. An important property of automotive fuels is the resistance to autoignition. The goal of the present work is

Carbon/Carbon Composites

2018
Carbon fiber-reinforced carbon matrix composites (C/C composites) have excellent properties such as specific strength and specific elastic modulus, along with excellent fatigue resistance, thermal shock resistance, ablation resistance, frictional properties, lightweight, heat/thermal conductivity, and dimensional stability.

Black Carbon and the Carbon Cycle

Science, 1998
When vegetation and fossil fuels burn, the combustion creates "black carbon" that becomes distributed throughout the environment. Determining how it is created and where it goes is important for studying the past history of fire and for understanding global carbon and oxygen budgets.

Carbon Nanomembranes

Advanced Materials, 2016
Carbon nanomembranes (CNMs) are synthetic 2D carbon sheets with tailored physical or chemical properties. These depend on the structure, molecular composition, and surroundings on either side. Due to their molecular thickness, they can be regarded as “interfaces without bulk” separating regions of different gaseous, liquid, or solid components and ...

On the Strength of Carbon-Hydrogen and Carbon-Carbon Bonds

The Journal of Chemical Physics, 1942
Electron impact critical potentials are combined with thermochemical data to obtain values for the heats of the dissociation reactions, CH4=CH3+H, C2H6=C2H5+H, C2H6=2CH3, and nC4H10=2C2H5. The values found are: D(CH3–H)=101 kcal./mole, D(C2H5–H)=96 kcal./mole, D(CH3–CH3)=82.6 kcal./mole and D (C2H5–C2H5)=77.6 kcal./mole.
