Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT The lack of diverse active sites in single‐component catalysts inevitably leads to a competitive adsorption dilemma between 5‐hydroxymethylfurfural (HMF) and OH−, impeding the kinetics of electrocatalytic oxidation of HMF (EC‐HMFOR). Herein, we deliver an interfacial engineering strategy by constructing a rare‐earth metal oxide heterostructure

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Powder metallurgy (PM) near‐α Ti alloys are often constrained by a pronounced strength–ductility trade‐off, due to the coarse lamellar microstructure formed during the sintering process. To address this issue, a thermomechanical route combining cyclic hot rolling with short‐time solution treatment was developed to improve the mechanical ...

Grain Boundary Density Governs the Discharge Behavior of Mg Anodes in Biodegradable Batteries
Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT Biodegradable magnesium (Mg) alloys have entered clinical use, yet their development as self‐powered absorbable batteries is hindered by poor anode performance, including high self‐corrosion, passivation, and nonuniform dissolution. The role of grain boundary density in governing discharge behavior remains unclear.

, 2007 研究了不同调控措施下辽东栎灌丛再萌生株各生长因子的特征,分析了不同的人为调控措施对辽东栎次生灌丛再萌生能力的影响.结果表明,人为调控对辽东栎再萌生株的发生与生长有着重大影响.调控强度大,再萌生株的数量、高度较小,基径、单株生物量较大;调控强度小,再萌生株的数量、高度较大,基径、单株生物量较小.在辽东栎种群的更新过程中,幼苗与幼树间存在着明显的瓶颈现象,经过激烈的竞争生长,只有少数才能进入下一个生长季.生长季前清除所有再萌生株后,由于当年生长季调控措施的不同,再萌生能力出现差异.调控后 ...

基于逐次变分模态分解的飞轮-火电一次调频控制策略 [PDF]
全球能源互联网随着新型电力系统的大力建设与推广，火电机组面临的调频压力增大，提出一种逐次变分模态分解的飞轮-火电一次调频控制策略。首先，以飞轮储能和火电机组为研究对象，建立考虑新能源占比的飞轮-火电一次调频模型；其次，将一次调频功率指令利用逐次变分模态方法分解，由火电机组响应分解后的低频功率指令，同时设计飞轮储能下垂优化控制方法，实现飞轮储能与火电机组响应频率变化的协同控制；最后在不同工况下仿真验证，结果表明所提策略可有效避免火电机组一次调频时的频繁出力，减小火电机组响应频率变化时的调控要求 ...
