Controlling the pirouetting motion in rotaxanes by counterion exchange
(American Chemical Society, 2014-07-25)
A fine control of the pirouetting motion of rotaxanes was achieved by using a series of metallabisdicarbollides. The latter were used as anions in the protonated form of benzylic amide macrocycle-containing fumaramide ...
Phosphate diester cleavage, DNA interaction and cytotoxic Activity of a bimetallic bis(1,4,7-triazacyclononane) zinc complex
(Wiley, 2014-06-24)
The dinuclear zinc complex [Zn-2{bcmp(-H)}(mu-Cl)](ClO4)(2)center dot H2O {bcmp = 2,6-bis(1,4,7-triazacyclonon-1-ylmethyl)-4-methylphenol} has been synthesized and structurally characterized. The DNA binding affinity was ...
Manipulation of intestinal epithelial cell function by the cell contact-dependent type III secretion systems of Vibrio parahaemolyticus
(Frontiers Media, 2014-01-10)
Vibrio parahaemolyticus elicits gastroenteritis by deploying Type III Secretion Systems (TTSS) to deliver effector proteins into epithelial cells of the human intestinal tract. The bacteria must adhere to the human cells ...
The pyrolysis of 2-methylfuran: a quantum chemical, statistical rate theory and kinetic modelling study
(Royal Society of Chemistry, 2014-01-27)
Due to the rapidly growing interest in the use of biomass derived furanic compounds as potential platform chemicals and fossil fuel replacements, there is a simultaneous need to understand the pyrolysis and combustion ...
Rate constant calculations of H-Atom abstraction reactions from ethers by H(O) over dot(2) radicals
(American Chemical Society, 2014-01-31)
In this work, we detail hydrogen atom abstraction reactions from six ethers by the hydroperoxyl radical, including dimethyl ether, ethyl methyl ether, propyl methyl ether, isopropyl methyl ether, butyl methyl ether, and ...
Oxidation of ethylene-air mixtures at elevated pressures, part 1: experimental results
(American Institute of Aeronautics and Astronautics, 2014-03-26)
Shock-tube experiments have been performed to determine ignition delay times of undiluted ethylene air mixtures for temperatures from 1003 to 1401 K, at equivalence ratios from 0.3 to 2.0, and at pressures from 1.1 to 24.9 ...
Oxidation of ethylene-air mixtures at elevated pressures, part 2: chemical kinetics
(American Institute of Aeronautics and Astronautics, 2014-03-27)
A chemical kinetics submechanism for small molecular weight hydrocarbons was modified by adjusting rate constants to produce better agreement with recent ethylene ignition delay time data compared with an earlier version ...
Theoretical chemical kinetic study of the h-atom abstraction reactions from aldehydes and acids by Ḣ Atoms and ȮH, HȮ2, and ĊH3 radicals
(American Chemical Society, 2014-11-11)
We have performed a systematic, theoretical chemical kinetic investigation of H atom abstraction by H atoms and OH, HO2, and CH3 radicals from aldehydes (methanal, ethanal, propanal, and isobutanal) and acids (methanoic ...
Comparison of the performance of several recent hydrogen combustion mechanisms
(Elsevier ScienceDirect, 2014-03-12)
A large set of experimental data was accumulated for hydrogen combustion: ignition measurements in shock tubes (770 data points in 53 datasets) and rapid compression machines (229/20), concentration time profiles in flow ...
A comprehensive combustion chemistry study of 2,5-dimethylhexane
(Elsevier ScienceDirect, 2014-01-16)
Iso-paraffinic molecular structures larger than seven carbon atoms in chain length are commonly found in conventional petroleum, Fischer-Tropsch (FT), and other alternative hydrocarbon fuels, but little research has been ...
