Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Photocatalytic hydrogen production from water splitting is a promising strategy for sustainable and clean energy generation. However, the design of low‐cost, highly active photocatalysts remains a critical challenge. In this study, covalent organic frameworks (COFs) were loaded onto the surface of Cd0.9Cu0.1S to fabricate COF/Cd0.9Cu0.1S ...

Constraints on timing of the early-paleoproterozoic magmatism and crustal evolution of the Oulongbuluke microcontinent: U-Pb and Lu-Hf isotope systematics of zircons from Mohe granitic pluton [PDF]
, 2007 The Olongbuluke micro-continent is composed of a two-fold basement with cover strata. The lower basement is the medium-to high-grade Delingha complex (DC) and the Dakendaban Group, the upper is the low-grade Wandonggou Group.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

活性碳上羧酸根锚定AuCl3催化乙炔氢氯化反应的理论研究 [PDF]
, 2018 采用密度泛函B3LYP方法,运用分子模型对活性碳（AC）上羧酸根负载AuClx催化剂的活性结构、稳定性以及催化乙炔氢氯化反应机制进行了详细的理论探讨。结果表明,AuCl3催化剂可以被表面羧酸根单中心级分散锚定,形成AC-COOH-AuCl3表面活性中心,进而在氢氯化过程中与乙炔发生协同加成生成氯乙烯,同时形成具有螯合结构的表面活性中心AC-CO2>AuCl2,进而催化氢氯化反应遵循分步反应异步加成机制:乙炔活化吸附到Au（Ⅲ）中心,HCl异裂亲核加成到乙炔伴随羧酸根质子化,分子内质子迁移形成Au（Ⅲ ...

Differences in hydrocarbon generation kinetics between shale and tar-rich coal and temperature conditions for in-situ co-production [PDF]
The area of shale exhibiting middle- to low-maturity constitutes over 90% of the total shale area within the seventh Member of the Yanchang Formation (Chang 7 Member) in the Ordos Basin. Additionally, the tar-rich coal resources of the Lower-Jurassic Yan’

The Microstructure Evolution and Mechanical Properties of (FeCoCrNi)100‐x(AlCu)x High‐Entropy Alloys
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT This study systematically investigates the effects of AlCu addition on the microstructural evolution and mechanical properties of (FeCoCrNi)100‐x(AlCu)x (x = 0, 5, 10, 15, 20; at%) high‐entropy alloys (HEAs). The results reveal that the microstructure evolves from coarse equiaxed to refined equiaxed, dendritic, and ultimately dual‐phase ...

Plasma‐Boosted Bi2Mn4O10 Electrocatalysis Enables Real‐Time On‐Board Monitoring of CO2 in Exhaust
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Real‐time monitoring of CO2 concentration in automobile exhaust is critical for effective carbon emission reduction. However, the inherently inert nature of CO2 poses a significant challenge for achieving accurate and efficient detection in the exhaust automobile environment.

Thermodynamics and kinetics of D-glyceric acid adsorption on ion exchange resin [PDF]
, 2016 D-甘油酸是一种重要的甘油衍生物,具有解酒护肝的功能。关于D-甘油酸生产方法的研究已有不少,但对其分离方法及分离机理的研究却鲜见报道。通过静态吸附实验,研究了D-甘油酸在201×7阴离子交换树脂上的等温热力学和动力学特性。结果表明,D-甘油酸在201×7阴离子交换树脂上的最大平衡吸附容量随p H的增加而降低,其吸附等温线符合Freundlich模型。在293~308 K下,吸附焓变为14.77 k J·mol-1,表明该吸附过程为吸热过程。升高温度有利于提高吸附速率,但对最大平衡吸附容量影响不大。同时 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Biomass‐derived quinones are promising green and sustainable cathode materials for sodium‐ion batteries (SIBs), yet their practical application is hindered by poor cycling stability due to dissolution in conventional electrolytes. Herein, we demonstrate that sodiumation is an effective strategy to enhance both rate capability and cycling ...
