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.

Carbon Nanonecklaces with Carbon Nanotubes and Carbon Dots

2017
Carbon nanoparticles (CNP) have gained significant attention representing unique carbon-based nanomaterials that find applications in various fields of science and technology. Carbon nanotubes (CNTs) and carbon dots (CDs) have now been widely employed as an electrode in super capacitors, as fluorescent nanomaterials for imaging and for fuel cell ...

Carbon–Carbon Coupling Constants: Discussion

1981
Publisher Summary This chapter discusses the carbon-carbon coupling constants. The field of carbon-carbon coupling constants is in an expansive period with most of the new information coming from biosynthetic studies. Interest in carbon-carbon coupling constants has increased dramatically in the recent years.

Carbon-Carbon Composites

1998
Carbon-carbon (CC) materials are a generic class of composites similar to the graphite/epoxy family of polymer matrix composites. These materials can be made in a wide variety of forms, from one-dimensional to n-dimensional, using unidirectional tows, tapes, or woven cloth (Fig. 15.1).
