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 ...

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 ...

Visible‐Light‐Excited Optical Thermometry in Ca3Sc2Si3O12: Er3+ via an Efficient Eu2+ Bridge
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Er3+ ions are promising for optical thermometry due to their thermally coupled levels. However, their parity‐forbidden transitions result in weak and narrowband absorption, which restricts excitation to infrared lasers (e.g., 808, 980, or 1550 nm). Moreover, the single emission center inherently limits temperature sensitivity. In this work, we

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...
