Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The limited crack resistance of coarse grain boundaries and coarse interfaces leads to an incompatibility between high‐temperature strength and ductility in TiAl alloys. Tailoring stress‐oriented textures and multiscale heterogeneous interfaces can effectively impede crack propagation, thereby overcoming this trade‐off.

Gongye shui chuli, 2014 采用水溶液聚合法合成聚二甲基二烯丙基氯化铵-丙烯酰胺（Poly-DMDAAC-AM，PDA），研究了体系溶液的pH、n（AM）：n（DMDAAC）、引发剂投加量等因素对合成PDA的影响，当pH=3、n（AM）：n（DMDAAC）=4：1、引发剂浓度为1.0×10-4 mol/L时，合成的PDA产品相对分子质量和阳离子离子度最高。采用合成的PDA与无机盐对城市污泥进行调理后顺利达到国家环保部关于加强城镇污水处理厂污泥污染防治的要求，成功实现污泥深度脱水。

Efficient Photocatalytic Removal of Toluene by Synergistic FeCe/TiO2: Performance and Mechanism
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Efficient removal of volatile organic compounds (VOCs) in confined spaces is crucial for environments such as spacecraft and deep‐sea submarines. Metal modification is an effective strategy to enhance the light absorption capacity of titanium dioxide (TiO2) and suppress the recombination of photogenerated charge carriers.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

双冠醚的研究.Ⅱ.酮型、烃型和醇型双(4′-苯并-15-冠-5)与碱金属苦味酸盐相作用的吸收光谱
四川大学学报. 自然科学版, 1987 用光谱法研究了酮型,烃型和醇型三个系列双（4′—苯并—15—冠—5）与碱金属苦味酸盐在四氢呋喃溶液中的格络作用.△λmax数据表明,这些双（4′—苯并—15—冠—5）与Na+的络合作用很弱,与相应的单苯并—15—冠—5类似,但对K+、Rb+则有较大的络合能力。三个系列双（4′—苯并—15—冠—s）与离子半径较大的碱金属离子络合时,倾向于生成冠醚环与离子化学计量为2:1 的夹心络合物。生成这种2:l络合物的络合能力大小的顺序分别是3>2>1和K+>Rb+>CS+.络合能力小的酮型双（4′—苯并—15—冠 ...
