Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional electrocatalysts is a key challenge for the industrialization of hydrogen production by water electrolysis. In this work, Co‐doped NiS/Ni3S2 heterostructured nanowire arrays (Co–NiS/Ni3S2 NA) were successfully constructed by precisely modulating the phase‐selective behavior of nickel ...

Shuitu Baochi Xuebao, 2007 选择酸性紫色土,研究pH和有机酸对紫色土吸附镉的影响。结果表明,pH在1.0~5.0的范围内,Cd2 的解吸率从接近100%急剧降低到20.0%。当pH>5.0,Cd2 的解吸率缓慢下降。相对较低的有机酸浓度(≤10-3mol/L)限制了Cd2 解吸,而较高的有机酸浓度则增加了Cd2 的解吸。柠檬酸和醋酸在较高浓度(>10-3mol/L)时极大地促进了Cd2 的解吸,其次是苹果酸,最小的是酒石酸。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Chemically self‐charging aqueous zinc‐ion batteries (AZIBs) have emerged as promising candidates for energy storage technologies owing to their environmental autonomy and structural simplicity. Nonetheless, the self‐charging performance is significantly compromised by the limited potential difference between cathodes and oxygen, as well as the

Shuitu Baochi Xuebao, 2011 模拟东北林区森林凋落物淋洗液中低分子有机酸浓度范围,研究了不同浓度外源草酸、柠檬酸溶液对暗棕壤中P、Fe、K等养分元素有效性、以及落叶松和水曲柳幼苗吸收P、Fe、K的影响.结果表明,合适浓度的草酸和柠檬酸促进暗棕壤中磷的活化,并促进落叶松和水曲柳苗木根系对磷的吸收,但较高浓度时(50.0 mmol/L)水曲柳叶片含磷量却降低;合适浓度草酸和柠檬酸促进暗棕壤中Fe、K等金属元素的活化释放,并促进落叶松和水曲柳幼苗对Fe、K的吸收和运输;在有机酸活化土壤P、Fe、K养分、促进林木吸收的过程中 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...

Dianci bileiqi, 1987 对磷酸—有机添加剂与电瓷干坯强度间的关系做了探索性的研究。认为磷酸（盐）能大幅度地提高电瓷干坯的强度,其中以磷酸的效果最明显。如选择适当分子量和聚合度的高分子化合物组成磷酸—有机添加剂,则能使强度提高了的坯体保持良好的上釉性能。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Aqueous vanadium dioxide (VO2)‐based smart thermal insulation coatings represent a viable strategy to decrease building energy consumption and advance sustainable development goals. However, the inherent instability and limited compatibility with polymer matrices of VO2 hinder its widespread application.

Zhongguo shiyan zhenduanxue, 2022 齐墩果酸（3β-hydroxyolean-12-en-28-oicacid,OA）是一种齐墩果烷型的五环三萜类化合物，目前临床上主要用于治疗急性黄疸型肝炎和慢性病毒性肝炎，已有研究证实齐墩果酸具有抗肿瘤、保肝、护肾、抗炎、降血糖血脂及抗血管新生等药学活性，虽然齐墩果酸具有多种活性，但存在水溶性差、生物利用度低的缺点。以上缺点在一定程度上对齐墩果酸的应用和研究开发造成了不同程度的制约，因此人们采用新型材料包合技术改变齐墩果酸的水溶性，从而提高其生物利用度，其中齐墩果酸纳米粒子不仅能够提高齐墩果酸水溶性 ...
