Two-dimensional(2D)transition-metal selenides,espe-cially MoSe_(2),is considered to be an excellent alternative electrocatalyst for the hydrogen evolution reaction(HER).However,it still features high overpotential in HER due to the low density of active sites,which limits its practical ***,the hydrogen evolution reaction activity of MoSe_(2)is enhanced by the incorporation of metal-cation,tungsten,which succeeds in taking the place of Mo in the lattice of MoSe_(2),inducing the spacing expansion and bringing new flexural edges to serve as active *** addition,the incorporated metal also facil-itates electron transport from Mo active center toward W and Se atoms with auspicious hydrogen adsorption prop-erties.

竹丛枝病可由多种病原引起,竹生香柱菌即是其中的一类,包括箣竹香柱菌(Epichloё bambusae)和箬竹香柱菌(Epichloё sasae)两种。日本学者Tanaka根据形态结合分子的研究结果,将其更名为箣竹异香柱菌(Heteroepichloё bambusae)和箬竹异香柱菌(Heteroepichloё sasae)。该文作者于2007年5月底从安徽省广德县的短穗竹上采集到1种异香柱型丛枝病标本,对其病原菌的形态学和培养特征进行观察描述,并利用ITS rDNA序列对其系统发育学进行分析,最终确定该菌为箬竹异香柱菌,而不是先前认为的箣竹异香柱菌。鉴于国内有关其他寄主上的竹生异香柱菌的描述模糊,并且绘图非常简单,因此建议对我国竹生的异香柱菌形态学和寄主范围进行研究,特别是利用分子生物学手段确定它们的分类学地位。
