标准 DNA 条形码凭借通用引物适配性强和测序成本低等优势，广泛应用于生物多样性保护与溯源等领域。针对近缘种、杂交频繁及近期辐射演化的复杂类群，标准 DNA 条形码因序列变异度有限，分辨率不足，难以满足精准鉴定的需求。尽管基因组浅层测序获取质体全基因组（超级条形码）的策略提升了部分困难类群的鉴别率，但质体基因组的单亲遗传特性使其在杂交渐渗类群分析中存在局限。
Water electrolysis uses renewable electricity to produce clean hydrogen. Among various technologies, anion-exchange membrane (AEM) water electrolysis combines the advantages of alkaline systems and proton-exchange membrane systems. However, its large-scale application is limited by slow oxygen evolution reaction and the need for catalysts with high activity and long-term stability. In a study publ

Metals, semiconductors and insulators are fundamental components of modern electronics. However, efforts to improve device performance have largely focused on semiconductor quality, while metal crystallinity has received far less attention. As transistor dimensions continue to shrink, though, structural disorder in metals and at metal-semiconductor interfaces increasingly impedes carrier injection
