Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

Gongye shui chuli, 2008 不同聚合度的聚乙二醇单甲醚丙烯酸酯分别与丙烯酸(AA)在水溶液中聚合,得到两种聚醚型共聚物阻垢剂T-400和T-1000。考察了阻垢剂用量、钙离子浓度、溶液pH,以及温度、时间对其阻磷酸钙垢率的影响,并与其他阻垢剂进行了比较。结果表明,聚醚型阻垢剂具有优异的阻磷酸钙垢的性能,对钙离子容忍度较高,受温度影响较小,可用于高pH的水系统中,并长时间有效;聚醚侧基的聚合度大小对其阻磷酸钙垢性能影响不大。

Gongye shui chuli, 2016 为了解聚合铝的混凝作用机理,以不同碱化度的聚合铝为混凝剂,考察了pH对聚合铝的形态分布、混凝效果及总溶解性残余铝的影响。结果表明,pH对聚合铝形态分布的影响十分明显,碱化度越低影响越显著;预制Alb和Alc在混凝过程中相对比较稳定,而低聚合度的Ala受pH影响显著;Ala在混凝过程中表现出阳离子的性质,电中和能力弱;与高Alb含量的聚合铝相比,高Alc含量的聚合铝出水浊度降低,但不能提高出水中的溶解性有机物去除率;总溶解性残余铝含量与混凝过程中Ala的含量有直接关联。
