Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction

Description: Authors of the article assert that rate coefficients, k1(T), for the gas-phase reaction of the OH radical with Furan-2,5-dione (maleic anhydride (MA), C4H2O3), a biomass burning related compound, were measured under pseudo first-order conditions in OH using the pulsed laser photolysis - laser induced fluorescence method over a range of temperature and bath gas pressure. Their results are compared with a previous room temperature relative rate study of the OH + MA reaction and significant discre… more

Ignition delay times of NH3/DME blends at high pressure and low DME fraction: RCM experiments and simulations

Description: Authors of the article describe how autoignition delay times of ammonia/dimethyl ether (NH3/DME) mixtures were measured in a rapid compression machine with DME fractions of 0, 2 and 5 and 100% in the fuel. Analysis of the mechanism indicates that this 'early DME oxidation' generates reactive species that initiate the oxidation of ammonia, which in turn begins heat release that raises the temperature and accelerates the oxidation process towards ignition. This is the accepted manuscript version … more

Oxidation of methylamine

Description: Article describes how a detailed chemical kinetic model for oxidation of methylamine has been developed, based on theoretical work and a critical evaluation of data from the literature. The mechanism was validated against experimental results from batch reactors, flow reactors, shock tubes, and premixed flames. This is the accepted manuscript version of the published article.

Acetaldehyde oxidation at elevated pressure

Description: A detailed chemical kinetic model for oxidation of CH3CHO at intermediate to high temperature and elevated pressure has been developed and evaluated by comparing predictions to novel high-pressure flow reactor experiments as well as shock tube ignition delay measurements and jet-stirred reactor data from literature. The flow reactor experiments were conducted with a slightly lean CH3CHO/O2 mixture highly diluted in N2 at 600–900 K and pressures of 25 and 100 bar. This is the accepted manuscript… more

Selective Noncatalytic Reduction of NOx Using Ammonium Sulfate

Description: Article discusses how ammonium sulfate (AS) is of interest as an additive in stationary combustion plants for the simultaneous control of NOx (through selective noncatalytic reduction, SNCR) and deposition and corrosion (through sulfation of alkali chlorides). The results indicated that sulfur from ammonium sulfate is mainly released as SO3, even though SO2 is detected in increasing concentrations at temperatures above 1000 °C. This is the accepted manuscript version of the published article.

Kinetic fall-off behavior for the Cl + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction

Description: Article discusses how rate coefficients, k, for the gas-phase Cl + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction were measured over the 15–500 torr (He and N2 bath gas) pressure range at temperatures between 283 and 323 K. An atmospheric degradation mechanism for C4H2O3 is proposed based on the observed product yields and theoretical calculations of ring-opening pathways and activation barrier energies at the CBS-QB3 level of theory. This is the accepted manuscript version of the publishe… more

New reactions of diazene and related species for modelling combustion of amine fuels

Description: Article discusses how potential energy surfaces for reactions involving N2H2 isomers of diazene (diimide) have been explored using density functional theory, with energies based on coupled-cluster theory. A focus is on processes that create or consume these species, and isomerization between the E (trans) and Z (cis) forms of HNNH. This is the accepted manuscript version of the published article.

Predicting Student Success with and without Library Instruction

Description: Conference proceedings paper sharing a study to determine the impact that "one-shot" library instruction sessions had on students' success in two foundational English courses. Overall, attendance in library instruction had a small but statistically significant impact on student success metrics. The main purpose of this analysis was to demonstrate the value of predictive modeling of student success and identify the key groups for which library instruction could provide the most impact. This is t… more
