Phosphine is a small redox-active gas that used to protect global grain reserves, which are threatened by the emergence of phosphine resistance in pest insects. We find polymorphisms responsible for genetic cluster around catalytic disulfide or dimerization interface dihydrolipoamide dehydrogenase (DLD) insects (Rhyzopertha dominica and Tribolium castaneum) nematodes (Caenorhabditis elegans). DLD core metabolic enzyme representing new class factor toxin. It participates four key steps...
Abstract Herein, an environmentally friendly electrochemical approach is reported that takes advantage of the captodative effect and delocalization to generate nitrogen‐centered radicals (NCRs). By changing reaction parameters electrode material feedstock solubility, dearomatization enabled a selective dehydrogenative C−N versus N−N bond formation reaction. Hence, pyrido[1,2‐ ]benzimidazole tetraarylhydrazine frameworks were prepared through sustainable transition‐metal‐ exogenous...

The growth behavior and magnetic properties of ${\mathrm{Si}}_{n}\mathrm{Fe}\phantom{\rule{0.2em}{0ex}}(n=2--14)$ clusters have been investigated using the density functional theory (DFT) within generalized gradient approximation (GGA). Extensive search lowest-energy structures has conducted by considering a number structural isomers for each cluster size. In ground state ${\mathrm{Si}}_{n}\mathrm{Fe}$ clusters, equilibrium site Fe atom gradually moves from convex, to surface, concave as Si...

Abstract Reported herein is an environmentally benign electrochemical C−H bond dehydrogenative amination protocol for the construction of privileged carbazole moiety with broad generality. Preliminary mechanistic investigations implied a radical reaction pathway. Compared traditional ionic routes, scalable transition‐metal and exogenous‐oxidant free strategy highlighted green sustainable nature this method. magnified image

ABSTRACT Cheeses with 60% reduced fat were prepared three mimetics and viscoelasticity was studied. Storage loss moduli of low‐fat cheeses made a carbohydrate‐based mimetic greater (p < 0.05) than those two protein‐based or control cheese, but smaller the storage full‐fat cheese. A six‐element Kelvin model properly predicted creep compliance for cheese without mimetics. Low‐fat had network structure more similar to samples

Without the use of catalysts and oxidants, a facile sustainable electrochemical bromination protocol was developed. By introducing directing groups, regioselectivity pyridine derivatives could be controlled at meta-position utilizing inexpensive safe bromine salts room temperature. A variety brominated were obtained in 28–95% yields, reaction readily performed gram scale. combining installation removing group, concept meta-bromination pyridines verified.
The lowest-energy structures of Cd(n)Te(n) (n=1-14) clusters have been studied by an unbiased simulated annealing search using first-principles molecular dynamics along with local optimization "handmade" density functional theory. After n>or=6, three-dimensional cage geometries are the configurations. Two families low-lying structures, hollow cages, and endohedral or core-shell cages found. begin to appear from n=10, they become more energetically preferred than for n>or=12. Cd(13)Te(13)...
