Direct ethylene glycol synthesis
WebJun 24, 2024 · High-entropy alloy nanoparticles (HEA NPs) emerged as catalysts with superior performances that are not shown in monometallic catalysts. Although many kinds of synthesis techniques of HEA NPs have been developed recently, synthesizing HEA NPs with ultrasmall particle size and narrow size distribution remains challenging because … WebEthylene is synthesized in flowering plants from methionine via a cyclic pathway, which preserves the methylthio group of methionine while using ATP. Two notable intermediates in the cycle are S-adenosyl-methionine and 1-aminocyclopropane-l-carboxylic acid; the latter compound is the immediate precursor of ethylene.
