Computational study of the gas-phase reactions of sulfuric acid with OH(ΠJ), O(3PJ), Cl(2P) and O(1D2) radicals (open access)

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.

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

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

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 of the published article.

Acetaldehyde oxidation at elevated pressure (open access)

Acetaldehyde oxidation at elevated pressure

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 version of the published article.

Selective Noncatalytic Reduction of NOx Using Ammonium Sulfate (open access)

Selective Noncatalytic Reduction of NOx Using Ammonium Sulfate

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 (open access)

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

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 published article.

Elucidating the role of negative parenting in the genetic v. environmental influences on adult psychopathic traits (open access)

Elucidating the role of negative parenting in the genetic v. environmental influences on adult psychopathic traits

Article states that though adult psychopathic traits emerge from both genetic and environmental risk, no studies have examined etiologic associations between adult psychopathic traits and experiences of parenting in childhood, or the extent to which parenting practices may impact the heritability of adult psychopathic traits using a genetically-informed design. Utilizing a genetically-informed design, the authors found that both genetic and non-shared environmental factors contribute to the emergence of psychopathic traits.

Temporal Variations and Spatial Disparities in Public Sentiment Toward COVID-19 and Preventive Practices in the United States: Infodemiology Study of Tweets

Article discusses how, during the COVID-19 pandemic, US public health authorities and county, state, and federal governments recommended or ordered certain preventative practices, such as wearing masks, to reduce the spread of the disease. The purpose of this study was to understand the variations in public sentiment toward COVID-19 and the recommended or ordered preventive practices from the temporal and spatial perspectives, as well as how the variations in public sentiment are related to geographical and socioeconomic factors.

Spatial and temporal localization of SPIRRIG and WAVE/SCAR reveal roles for these proteins in actin-mediated root hair development (open access)

Spatial and temporal localization of SPIRRIG and WAVE/SCAR reveal roles for these proteins in actin-mediated root hair development

Article shows that SPIRRIG (SPI), a beige and Chediak Higashi domain-containing protein involved in membrane trafficking, and BRK1 and SCAR2, subunits of the WAVE/SCAR (W/SC) actin nucleating promoting complex, display polarized localizations in Arabidopsis thaliana root hairs during distinct developmental stages. Authors' work uncovers a role for SPI in facilitating actin-dependent root hair development in Arabidopsis through pathways that might intersect with W/SC.

Descriptive Complexity in Cantor Series

Article discusses how a Cantor series expansion for a real number x with respect to a basic sequence Q=(q), where qi≥2, is a generalization of the base b expansion to an infinite sequence of bases. The authors show that for any basic sequence the set of distribution normal numbers is Π03-complete, and if Q is 1-divergent then the sets of normal and ratio normal numbers are Π03-complete.
