Gongye shui chuli, 2004 流动注射分析具有试样区带在时间空间上的分散高度重现这一特点。据此,提出利用流动注射梯度稀释技术来分析炉水中的磷。试验中采集标准样扫描曲线上不同延迟时间点对应的吸光度数据,建立起一系列不同稀释程度的校准曲线。该方法快速简便,含磷水样不经稀释就可直接进行测定。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Nickel‐based materials are highly remarkable as promising transition metal catalysts for the electrochemical hydrogen evolution reaction (HER) in alkaline electrolytes. However, their electrochemical performance is limited by an unfavorable d‐band energy (Ed) level. Herein, we showcase an effective lattice‐strain strategy to modulate the Ed of

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Lithium‐selenium (Li‐Se) batteries have attracted considerable attention due to their high theoretical specific capacity and the intrinsically good electronic conductivity of selenium. Nevertheless, low active‐material utilization, parasitic side reactions, and sluggish reaction kinetics hinder their practical application.

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...
