How copper catalyzes the electroreduction of carbon dioxide into hydrocarbon fuels

, 2010
Density functional theory calculations explain copper's unique ability to convert CO2 into hydrocarbons, which may open up (photo-)electrochemical routes to fuels.

Inorganic Solid Acids and Their Use in Acid-Catalyzed Hydrocarbon Reactions

, 1995
It is possible to say that solid acid catalysis involves the largest amounts of catalysts used and the largest economical effort in the oil refining and chemical industry.

Thermodynamic properties of (hydrocarbon + hydrocarbon) and of (hydrocarbon + tetrachloromethane): lattice interpretation

The Journal of Chemical Thermodynamics, 1980
Abstract Experimental excess enthalpies and Gibbs free energies of (hydrocarbon + hydrocarbon) and of hydrocarbon + tetrachloromethane) were interpreted in terms of the lattice model. A table of internally consistent lattice constants was obtained for nine types of segments from molecules of tetrachloromethane, n-alkanes, branched alkanes ...

Magnetizability of Hydrocarbons

Journal of the American Chemical Society, 1994
The magnetizability of a large number of hydrocarbons-saturated, unsaturated, and aromatic-have been investigated by ab initio methods at the Hartree-Fock level. Gauge-origin independence and size extensivity are imposed by the use of London atomic orbitals (also known as gauge-invariant atomic orbitals).

Conformational analysis. 130. MM2. A hydrocarbon force field utilizing V1 and V2 torsional terms

, 1977
An improved force field for molecular mechanics calculations of the structures and energies of hydrocarbons is presented. The problem of simultaneously obtaining a sufficiently large gauche butane interaction energy while keeping the hydrogens small ...

Raman characteristics of hydrocarbon and hydrocarbon inclusions

Science in China Series D: Earth Sciences, 2007
The Raman spectrograms of hydrocarbon standard samples show that: (1) the Raman spectrogram of normal paraffin has very strong peaks of methyl and methylene (from 2700 cm−1 to 2970 cm−1); (2) branch methyl has the particular peak of 748 cm−1±; (3) six cyclic has the particular peak of 804 cm−1±; (4) phenyl has two particular peaks of 988 cm−1± and 3058

Activation of the aryl hydrocarbon receptor by structurally diverse exogenous and endogenous chemicals.

Annual Review of Pharmacology and Toxicology, 2003
The induction of expression of genes for xenobiotic metabolizing enzymes in response to chemical insult is an adaptive response found in most organisms. In vertebrates, the AhR is one of several chemical/ligand-dependent intracellular receptors that can ...

Note on Hydrocarbons, No. 1: Saturated Hydrocarbons

Energy Sources, 1987
A new nomenclature system for the linear saturated hydrocarbons is proposed. It has many advantages including determination of the physical properties of hydrocarbons.

Simplified Reaction Mechanisms for the Oxidation of Hydrocarbon Fuels in Flames

, 1981
Simplified reaction mechanisms for the oxidation of hydrocarbon fuels have been examined using a numerical laminar flame model. The types of mechanisms studied include one and two global reaction steps as well as quasi-global mechanisms.
