Abstract:
... 24-Epibrassinolide (EBL) is considered the most probable brassinosteroid (BR) candidate that could be used for practical application in agriculture. EBL-induced stress-protective properties were evaluated in in vitro-grown tomato (Solanum lycopersicum L.) varieties Pusa Ruby (susceptible to nematodes) and PNR-7 (resistant to nematodes) during nematode pathogenesis. Sterilized tomato seeds treated ...

Novel multimetallic copper pyrazolate complexes, inaccessible using simple pyrazole ligands due to competing, alternative structural motifs, can be obtained by locking pairs of pyrazole ligands together with ethylene tethers. Nanojars based on this tethered pyrazole ligand display unexpected total selectivity for the carbonate over the sulfate ion. ...

Abstract:
... On the Qinghai–Tibetan Plateau, isotopic signatures in soil–atmosphere CH ₄ fluxes were investigated in nine grasslands and three wetlands. In the grasslands, the fractionation factor for soil CH ₄ uptake, α ₛₒᵢₗ, was much smaller than the usually reported value of 0.9975–1.0095. Stepwise multiple variation analysis indicates that α ₛₒᵢₗ is higher for higher soil water contents but is lower for hi ...

Abstract:
... Recently, utilizing CO₂ as a methylation reagent to construct functional chemicals has attracted significant attention. However, the conversion of CO₂ is still a challenge due to its inherent inertness. In this study, we have developed a catalyst-free N-methylation of amines to prepare numerous methylamines using CO₂ as a methyl source. By utilizing 2 eq. PhSiH₃ as the reductant, amines could unde ...
