The basic aim of this study was to compare the denitrification efficacy of 2,5-dichloroaniline, Ammonium Thiosulphate and their combination (1:1) with previous studies. Ammonium Thiosulphate was not used as a nitrification inhibitor in previous research. Our findings depict that there was significant variation among the chemicals, soil and levels in denitrification for early seedling growth of wheat.

Three chalcones with a 2,3-dihydrobenzofuran linkage were analyzed by applying the density functional theory (DFT) and B3LYP approach with the 6-311G(d,p) basis set in this report. Spectroscopic and theoretical analyses were used to examine the structures of these three chalcones. The chalcone molecules' HOMO-LUMO energy was determined. Chemical reactivity parameters and molecular electrostatic surface potential (MESP) plots were obtained to gain useful insight into the distribution of charge density.

Ebook "State-to-state dynamical research in the F+H2 reaction system" addresses two important and also challenging issues in the research of chemical reaction dynamics of F+H2 system. One is to probe the reaction resonance and the other is to determine the extent of the breakdown of the Born-Oppenheimer approximation (BOA) experimentally. The author introduces a state-of-the-art crossed molecular beam-scattering apparatus using a hydrogen atom Rydberg "tagging" time-of-flight method, and presents thorough state-to-state experimental studies to address the above issues.
