AB Initio kinetics of the reactions between BH4− + OH•
Tạp chí Khoa học và Công nghệ, 2023 Tetrahydroborate anion (BH4-) in Td symmetry group is a well-known hydrogen carrier, involved in various reactions to produce hydrogen gas. In this work, we reassessed the mechanism and kinetics of reactions between BH4- + OH• by using the DFT study. All

Test of variational transition state theory against accurate quantal results for a reaction with very large reaction-path curvature and a low barrier [PDF]
, 1984 We present three sets of calculations for the thermal rate constants of the collinear reaction I+HI-->IH+I: accurate quantum mechanics, conventional transition state theory (TST), and variational transition state theory (VTST). This reaction differs from

The Journal of Animal and Plant Sciences, 2023 Tomato is one of the best-studied cultivated dicotyledonous plants in molecular studies. Mobile genetic elements constitute large parts of plant genomes. Retrotransposons are mobile genetic elements within the genome and constitute more than 60% of the tomato genome.

Thermal spin-transfer in Fe-MgO-Fe tunnel junctions
, 2011 We compute thermal spin transfer torques (TST) in Fe-MgO-Fe tunnel junctions using a first principles wave function-matching method. At room temperature, the TST in a junction with 3 MgO monolayers amounts to 10^-7J/m^2/K, which is estimated to cause ...

Discordance of tuberculin skin test and interferon gamma release assay in recently exposed household contacts of pulmonary TB cases in Brazil. [PDF]
PLoS ONE, 2014 Interferon-gamma (IFN-γ) release assays (IGRAs) such as the Quantiferon Gold In-tube test are in vitro assays that measure IFN-γ release from T cells in response to M. tuberculosis (Mtb)-specific antigens.

The Use of Isomeric Testosterone Dimers to Explore Allosteric Effects in Substrate Binding to Cytochrome P450 CYP3A4 [PDF]
, 2016 : Cytochrome P450 CYP3A4 is the main drug-metabolizing enzyme in the human liver, being responsible for oxidation of 50% of all pharmaceuticals metabolized by human P450 enzymes.
