Featuring phase-change energy storage, a mobile thermal supply system (M-TES) demonstrates remarkable waste heat transfer capabilities across various spatial scales and temporal durations, thereby effectively optimizing the localized distribution structure—a pivotal contribution to attainment of objectives such as “carbon peak” neutral”. To heighten efficiency for heating, this research introdu...
That there is room for improvement in the medicinal treatment of angina of effort, no one will dispute. The clinical trial to be described was designed to test the efficacy of a khellin derivative, iproniazid, and the already widely used penta-erythritol tetranitrate, in the relief of anginal pain. THE DRUGS Penta-erythritol tetranitrate (P.E.T.N.) has the chemical formula CH20NO2 CH2ONO2 C CH2...
Earlier in vivo studies have shown that the sequential action of the IspG and IspH proteins is essential for the reductive transformation of 2C-methyl-d-erythritol 2,4-cyclodiphosphate into dimethylallyl diphosphate and isopentenyl diphosphate via 1-hydroxy-2-methyl-2-(E)-butenyl 4-diphosphate. A recombinant fusion protein comprising maltose binding protein and IspG protein domains was purified...
The carbonation of biosourced 1,2-diols is a sustainable avenue for the synthesis bis-five-membered cyclic carbonates (bis-5CCs), precursors valuable class polymers, example, polyhydroxyurethanes (PHUs). In this work, we performed direct optically pure sugar-based butadiene tetraols, namely, (i) meso-erythritol and (ii) its (S,S) diastereoisomer, (L)-threitol. corresponding vicinal bis-5CCs, er...
