Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Water electrolysis is a promising method for green hydrogen production, but slow hydrogen evolution reaction (HER) kinetics require efficient catalysts. In this study, we develop a Ni3S2/MoS2 heterostructure electrocatalyst using a work‐function‐driven electronic modulation strategy combined with a self‐sacrificial template approach.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Thermally driven hydrogenation of CO2 to light olefins (C2=–C4=) using metal oxide‐zeolite tandem catalysts is an effective strategy for achieving carbon neutrality. However, progress in this area is constrained by zeolite pore transport limitations, acid‐site inactivation, and surface carbon poisoning.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Developing oxygen evolution reaction (OER) catalysts that combine high performance with cost‐effectiveness is a critical challenge for advancing the commercialization of anion exchange membrane water electrolysis (AEMWE). Practical application is often hindered by issues such as poor batch reproducibility and low‐cost efficiency.

Gongye shui chuli, 2003 针对转炉除尘废水高pH、高硬度的水质特点,通过两种实验方法,选取复合配方的水质稳定剂,同时模拟废水的循环使用过程检验水质稳定剂的阻垢效果。结果表明,在高pH、高硬度的水质条件下,所选复合配方水质稳定剂有良好的阻垢性能;对于生产中所用的除尘废水,在高pH条件下,若Ca2+质量浓度<800mg L,所选阻垢剂可将结垢率控制在5%以下。

Gongye shui chuli, 2006 炼钢浊环水系统比较复杂。水的浊度、悬浮物含量、pH、总碱度均高。为了达到水质稳定，除需设置粗颗粒分离器及沉淀池等设施设备外，还需要投加絮凝剂、阻垢剂和缓蚀剂。这不仅增加了投药工作强度，也提高了水处理的药剂成本。根据炼钢浊环水系统的特点，作者开发了一种多功能水质稳定剂，实际应用结果表明仅需投加该复配药剂即可满足浊环水系统水质稳定的要求，既简单，又经济实用。
