融合光谱度量标记迁移和Tri-training的高光谱遥感图像半监督分类算法
大数据, 2023 针对海量的高光谱遥感图像光谱和丰富的空间信息中可用于分类的有标记样本远少于无标记样本的数据特性，提出了一种融合光谱度量标记迁移和Tri-training的高光谱遥感图像半监督光谱-空间分类算法。该算法提出了一种基于光谱度量的标记迁移方法，通过结合迁移标记和Tri-training预测标记进行扩充样本标记预测，提高了扩充样本标记的准确性。同时，该算法基于空间相关性选择扩充样本，综合运用光谱和空间特征提升图像分类的精度。在两个公开的高光谱遥感图像数据集上进行了实验，结果表明该算法优于基于Tri ...

Zhejiang Daxue xuebao. Lixue ban, 2004 用溶胶-凝胶法合成了发蓝绿光的4SrO·7Al2O3:Eu2+高显色荧光粉.从XRD、DTA以及红外谱图得出当干凝胶经1200℃灼烧可以完全形成4 SrO·7Al2O3晶相,这比用高温固相合成法低了200℃.通过激发光谱和发射光谱分析其发光特性,随着灼烧温度的升高,其发光强度增大.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Fast‐charging capability is one of the crucial factors determining the application prospects of sodium‐ion batteries (SIBs). Nevertheless, the mismatched sodium storage kinetics and Coulombic efficiency (CE) in hard carbon anodes are bottlenecks in the implementation of fast‐charging SIBs. Herein, we propose a facile pre‐carbonization strategy

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The electrocatalytic co‐reduction of CO2 and nitrate (NO3− ${\text{NO}}_{3}^{-}$) to synthesize urea presents a sustainable alternative to traditional industrial processes, yet its efficiency is fundamentally limited by the kinetically mismatched activation and coupling of CO2 and NO3− ${\text{NO}}_{3}^{-}$.

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 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Although alloy‐based materials present potential for peroxymonosulfate (PMS) activation, metal ion leaching remains severely restricted during the pollution degradation process. Herein, the porous carbon‐supported Fe–Cu alloy derived from industrial copper slag was prepared to remove the organic pollutants from wastewater while inhibiting the ...
