Shuitu Baochi Xuebao, 2000 干旱缺水是提高干热河谷旱坡地粮食产量和提高植树造林成活率的主要制约因素。为了充分利用有限的降水，进行了旱坡地“地下地膜隔水墙”节水农业（节水造林）技术及果树节水灌溉栽培试验。结果表明，旱坡地粮食增产6.5%-20.2%，造林成活率提高20%-30％，果树栽培节水率60％－80％，且生长良好。

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Cu‐Based Catalysts Design Toward Electrochemical CO2 Reduction to Valuable Multi‐Carbons Products
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Electrochemical reduction of CO2 to multi‐carbon products (e.g., C2+, ethene, ethanol, etc.) not only effectively decreases the CO2 concentration in atmosphere but also shows great potential economic benefits due to these exploitable value‐added products. The Cu‐based catalysts have caught much attention in CO2 electroreduction due to the good

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Prelithiation is effective for compensating active lithium‐ion (Li+) loss in silicon (Si)‐based battery electrode materials. However, owing to the dynamic growth of the solid electrolyte interface (SEI), capacity fading remains the biggest challenge for the industrialization of Si electrodes.
