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

The Colloidal Stabilization of Carbon with Carbon: Carbon Nanobubbles as both Dispersant and Glue for Carbon Nanotubes

Angewandte Chemie, 2013
AbstractThe superior physical properties of carbon nanotubes (CNTs) have led to their broad application. Intrinsically, CNTs tend to agglomerate from hydrophobic interactions, which is highly undesirable for solution processing and device fabrication.

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.

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.

(Invited) A Carbon-Carbon Hybrid Immobilizing Carbon Nanodots and Carbon Nanotubes

ECS Meeting Abstracts, 2016
The thrust of this work is to integrate small and uniformly sized carbon nanodots (CND) with single-walled carbon nanotubes of different diameters as electron acceptors and electron donors, respectively, and to test their synergetic interactions in terms of optoelectronic devices.

Carbon/carbon supercapacitors

Journal of Energy Chemistry, 2013
Supercapacitors, or electrochemical capacitors, are a power storage system applied for harvesting energy and delivering pulses during short periods of time. The commercially available technology is based on charging an electrical double-layer (EDL), and using high surface area carbon electrodes in an organic electrolyte.

Carbon-carbon composite

Materials Science and Engineering: A, 1997
Abstract A problem in the production of carbon-carbon composites from carbon fiber reinforced thermoset composites through pyrolization is the cracking of the matrix due to internal stresses caused by the large shrinkage of the pyrolizing matrix and the simultaneous expansion of the fibers.
