image: PVDC在KOH的作用下进行脱卤反应，脱除Cl和H官能团，生成清洁的副产品KCl和H2O。此时脱除官能团的碳位点表现出较高的反应活性，与H3BO3偶联形成C-B或C-O-B键。此后，通过惰性退火得到了B掺杂的聚合C。SEM和HRTEM图像证明了O-BC-2-650具有三维互连的多孔结构以及 ...

image: PVDC undergoes dehalogenation in the presence of KOH, removing Cl and H functional groups to generate the clean byproducts KCl and H2O. The dehalogenated carbon sites exhibit very high ...

近日，Hospital de Mar Research Institute (IMIM)研究所研究人员发现蛋白质LOXL2在细胞核内发挥重要作用。研究人员还阐述了这一蛋白质对组蛋白H3的一种新的化学反应，组蛋白H3涉及乳腺癌、喉癌、肺癌和皮肤肿瘤的发展。 该研究由Sandra Peiró领导，相关研究论文已经发表 ...

在真核细胞中，组蛋白变体组装形成特殊的染色质结构，这种与常规组蛋白不同的染色质结构是表观遗传调控的重要方式之一。组蛋白变体H2A.Z与常规组蛋白H2A具有较为相似的一级序列，H2A.Z是多细胞生物的必需基因，且在基因转录调节、DNA损伤修复、细胞增殖 ...
