Engineering 2D Materials for High‐Current‐Density Electrocatalytic Water Splitting
Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Water electrolysis is a key method for sustainable hydrogen production, using water as an abundant resource. However, efficient and stable operation at high current densities remains challenging due to energy losses, catalyst degradation, and limited ion–electron transport.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Deep eutectic solvents (DESs) have displayed a significant potential in green recycling of spent lithium‐ion batteries (LIBs) cathode materials. In this study, we proposed a computational screening strategy based on the binding energy and hydrogen bonding performance via density functional theory and molecular dynamic calculation, achieving a ...

Integrative Conservation, Volume 4, Issue 4, Page 686-694, December 2025.The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

Gongye shui chuli, 1986 一、试验目的早在六十年代初,美国离子交换专家R.Kunin等就提出了以CO2作为弱酸阳离子交换树脂再生剂的设想。此法如能在生产上得到应用,显然有以下两个好处。一是,在有廉价CO2来源的场合,用CO2代替常用的再生剂HC1或H2SO4等,可使再生费用降低,同时也省去了运输和贮存强腐蚀性酸的麻烦。二是,可以根除再生废液对环境的污染问题。七十年代中,C.Berger Wittmar和H.

Gongye shui chuli, 2001 双室床调试中应注意控制好树脂和 EPS惰性白球的高度,最佳再生剂量可通过测定再生废液中残余酸 (碱 )度确定。运行中应按设计要求选用水源 ;阴床再生应先预热,再用 40℃热碱液再生 ;定期对树脂擦洗和活化,防止树脂污染,对已污染的树脂及早复苏。

Gongye shui chuli, 2008 药剂法是一种有效的丝状菌污泥膨胀控制技术。采用药剂法可使污泥膨胀在短时间内得到控制,在污泥膨胀得到迅速控制及膨胀原因查明后,再通过采取调控微生物生长环境的措施,创造不利于丝状菌生长的环境,可避免膨胀再次发生。药剂法能迅速控制污泥膨胀对于污水厂的运行管理具有较大的实用价值。

Gongye shui chuli, 1992 软化器是工厂企业主要耗水设备之一,为了做好软化器的节水工作,建议采取下述几项措施。1 将软化器顺流再生改为逆流再生有许多工厂企业目前使用的仍是顺流运行顺流再生软化器。如果将现有的顺流再生软化器改为逆流再生,可以节约软化器再生时的耗水量。软化器改为逆流再生后,可以免去大反洗过程,而以加再生液代替反洗。由于逆流再生的再生剂利用率高,废液量小,浓度低,正洗时间缩短,再生耗水量比顺流再生时可降低50%。直径1米的软化器再生一次可节水30米3。加之由于逆流再生工作周期延长。再生次数减少,节水量相当可观。
