Computational study of the gas-phase reactions of sulfuric acid with OH(ΠJ), O(3PJ), Cl(2P) and O(1D2) radicals
This article is about how rate coefficients for reactions of H2SO4 with OH, O(3P) and Cl radicals over 160–298 K were estimated computationally. The authors propose kOH = 8.5 × 10-14 exp(-50 K/T), kO = 1.1 × 10-12 exp(-5012 K/T) and kCl = 3.1 × 10-9 exp(-3314 K/T) cm3 molecule-1 s−1.

Experimental and Modeling Study of Water Time Histories during H2S-N2O Combustion in a Shock Tube
Article describes how, in the present study, the water formation was followed by laser absorption with N2O as an oxidant, instead of O2. Three H2S/N2O mixtures diluted in 98% Ar were studied to cover the following range of equivalence ratios: 0.5, 1.0, and 2.0, over a wide range of temperatures (1580–1940 K) around atmospheric pressure.

Measurement of the Intramolecular Hydrogen-Shift Rate Coefficient for the CH3SCH2OO Radical Between 314 and 433 K
Article describes how the intramolecular hydrogen-shift rate coefficient of the CH3SCH2O2 (methylthiomethylperoxy, MSP) radical, a product formed in the oxidation of dimethyl sulfide (DMS), was measured using a pulsed laser photolysis flow tube reactor coupled to a high-resolution time-of-flight chemical ionization mass spectrometer that measured the formation of the DMS degradation end product HOOCH2SCHO. Measurements performed over the temperature range of 314–433 K yielded a hydrogen-shift rate coefficient of k1(T) = (2.39 ± 0.7) × 109 exp(−(7278 ± 99)/T) s–1 Arrhenius expression and a value extrapolated to 298 K of 0.06 s–1.

Re-evaluation of rate constants for the reaction N2H4 (+ M) ⇄ NH2 + NH2 (+ M)
Article describes how rate constants for the dissociation/recombination reaction N2H4 (+ M) ⇄ NH2 + NH2 (+ M) are determined by a combination of quantum-chemical calculations and statistical unimolecular rate theory. Implications of the present re-evaluated rate constants for the modeling of high temperature ammonia oxidation kinetics are discussed, showing an only small influence of their precise values on the overall properties of the process.

Probing High-Temperature Amine Chemistry: Is the Reaction NH3 + NH2 ⇄ N2H3 + H2 Important?
Article describes how the reaction NH3 + NH2 ⇄ N2H3 + H2 (R1) has been identified as a key step to explain experimental results for pyrolysis and oxidation of ammonia. In the present work, the reaction was studied by ab initio theory and by reinterpretation of experimental data.

Reactions of hydrazine with the amidogen radical and atomic hydrogen
Article describes how the rate coefficient k1 for NH2 + N2H4 was measured to be (5.4 ± 0.4) × 10−14 cm3 molecule−1 s−1 at 296 K. The authors then describe how a combination of experiment and theory leads to a recommended rate coefficient for hydrogen abstraction of k1 = 6.3 × 10−23 T3.44 exp(+289 K/T) cm3 molecule−1 s−1.

Re-examination of the N2O+O reaction
This article is about how the reaction of N20 with O is a key step in consumption of nitrous oxide in thermal processes. In the present work ,the authors re-examined a wide range of experiments relevant for the N2O+O reaction through kinetic modeling, paying attention to the impact of artifacts such as impurities and surface reactions.

An experimental and modeling study on auto-ignition kinetics of ammonia/methanol mixtures at intermediate temperature and high pressure
Article describes how a rapid compression machine has been applied to measure the ignition delay times of NH3/CH3OH mixtures covering pressures of 20 and 40 bar, equivalence ratios of 0.5, 1.0 and 2.0, and temperatures between 845 and 1100 K. Analysis of the pressure profiles shows three distinct ignition modes for NH3/CH3OH mixtures, facilitated by the pre-ignition heat release from NH3 consumption. A detailed mechanism for ignition of NH3/CH3OH fuel blends has been developed, capable of reproducing the ignition behavior of mixtures with reasonable accuracy.
