ABSTRACT Improving the efficiency and stability of oxygen evolution electrocatalysts remains essential for advancing water splitting technologies. Although in situ surface reconstruction into active phases is desirable, it often leads to uncontrolled structural degradation.

ABSTRACT Balancing low iridium dosage and robust anodic stability remains a critical hurdle for practical proton exchange membrane water electrolysis (PEMWE). Although IrRuOx offers a cost‐effective alternative, current systems still suffer from the dual dilemma of excessive noble‐metal reliance and inadequate long‐term durability. Herein, we developed

揭示科学规律 再造秀美山川——水土保持研究所建所五十周年回顾
一漫漫水保路上世纪50年代初期,为适应新中国根治黄河的需要,由我国著名科学家竺可桢提议,中国科学院在陕西杨陵成立了她在西北地区的第一个科研机构——中国科学院西北农业生物研究所。研究所1954年筹建,1956年正式成立;1958年更名为“中国科学院西北水土保持生物土壤研究所”,1964年更名为“西北水土保持生物土壤研究所”,1979年更名为“中国科学院西北水土保持研究所”,1987年由中科院和水利部双重管理 ...

ABSTRACT Photocatalytic hydrogen peroxide (H2O2) production from water and oxygen driven by solar energy represents a highly promising green and sustainable strategy. Herein, lignin‐derived carbon quantum dots (LCDs) were strategically introduced at the heterojunction between a Bi‐based metal organic framework (Bi‐MOF) and ZnIn2S4 (ZIS).

濱海水層的水位受到潮汐變動之影響,多年來,一直是地下水領域研究重點之一,特別是針對水層幾何形狀效應、多層滲漏水層,及水層異向性等問題。本研究考慮具異向性的海岸滲漏含水層系統,其上層為非侷限含水層,下層為侷限含水層,中間夾著滲漏層。水層的東西兩側是感潮河川,水層的南側海岸緊鄰海洋,我們針對這種三側受潮汐影響的U型滲漏含水層,建立其地下水流的數學模式,並推導其水位變動的解析解。若假設水層為均質、等向、未滲漏系統,則前人研究所導得的許多解,皆可視為本解析解的特例。另外 ...

ABSTRACT Metal–organic framework (MOF) membranes are a novel class of composite membranes. They use crystalline porous MOF materials as separation layers or functional fillers. Because of their well‐ordered and tunable pore structures and highly controllable chemical environments, MOF membranes show broad application prospects in gas separation ...

ABSTRACT Gram‐negative (G−) bacterial infections, fueled by intrinsic antibiotic resistance stemming from their unique outer membrane architecture, pose a critical global clinical challenge. This study introduces a pioneering dual‐enzyme‐mimetic nanotherapy based on NaYbF4 nanoparticles (NaYbF4 NPs) that achieves synergistic antibacterial and anti ...
