Political Cycles, Electricity Policy, and Mexico's Economy
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

Study on reductive amination of biobased levulinic acid [PDF]
乙酰丙酸是重要的生物基平台化合物,其转化利用受到科研工作者的广泛关注。乙酰丙酸的还原胺化是制备高附加值乙酰丙酸胺化衍生产品的重要途径,近年来成为研究的热点。本论文建立了无催化剂乙酰丙酸还原胺化的反应体系,探讨了乙酰丙酸还原胺化合成直链氨基酸4-二甲氨基戊酸(4-DAPA)和环状化合物5-甲基-2-吡咯烷酮(5-MeP)的反应途径。 首先,研究了以N,N-二甲基甲酰胺为胺源,在无催化剂条件下直接还原胺化乙酰丙酸合成新型化合物4-二甲氨基戊酸(4-DAPA)的反应途径。在200℃条件下反应4h,4 ...

Cu‐Based Catalysts Design Toward Electrochemical CO2 Reduction to Valuable Multi‐Carbons Products
ABSTRACT Electrochemical reduction of CO2 to multi‐carbon products (e.g., C2+, ethene, ethanol, etc.) not only effectively decreases the CO2 concentration in atmosphere but also shows great potential economic benefits due to these exploitable value‐added products. The Cu‐based catalysts have caught much attention in CO2 electroreduction due to the good

The optimized expression technology of marine animal-sourced antimicrobial peptides in Pichia pastoris and the development of antimicrobial peptide as feedstuff additive [PDF]
抗生素污染问题是目前影响我国水产养殖业可持续健康发展的重大科技问题,抗生素(antibiotics)作为常用抗菌药物,被广泛应用于水产养殖业,但是抗生素超标所引起的细菌耐药性问题已成为全球公共健康问题,因此寻找抗生素的有效替代品是目前国内外本领域的研究热点之一。抗菌肽(antimicrobialpeptide)是先天性免疫的重要组分,广泛存在于生物界的各个门类,进化上相对保守,具有广谱抗菌活性、且不会产生细菌耐药性,被预言为最有希望替代抗生素的天然药物,具有广阔的应用前景 ...

ABSTRACT Prelithiation is effective for compensating active lithium‐ion (Li+) loss in silicon (Si)‐based battery electrode materials. However, owing to the dynamic growth of the solid electrolyte interface (SEI), capacity fading remains the biggest challenge for the industrialization of Si electrodes.
