Electrically Switchable Altermagnetism in Monolayer MoCl3
ABSTRACT Altermagnets intertwine spin‐split bands with vanishing net magnetization, offering great potential for high‐density, stray‐field‐free spintronic devices. However, their development is hindered by both material scarcity and difficulties in external control due to their intrinsic symmetry protection.

Research Progress and Prospect of Single‐Atom Materials in Tumor Catalytic Therapy
ABSTRACT Tumor catalytic therapy (TCT), an emerging therapeutic modality, exerts specific cytotoxic effects on tumor cells by catalyzing endogenous substances within the tumor microenvironment (TME)—including hydrogen peroxide (H2O2), glucose, and glutathione—to generate reactive oxygen species (ROS) or deplete protective biomolecules.

ABSTRACT Additive manufacturing of zinc‐magnesium (Zn‐Mg) alloys via laser powder bed fusion (LPBF) has gained significant recognition as a promising candidate for bone repair. However, the presence of coarse yet brittle eutectic phases in the fabricated Zn‐Mg alloys tends to induce premature stress concentration and resultant fracture during ...

采用固相烧结方法制得了具有K2NiF4结构的SrNdCoO4陶瓷,并对其磁性能进行了系统研究.结果发现,其磁化强度(M)分别在200K与20K附近随温度降低而迅速增大;150K,200K与275K下的磁化强度-磁场强度(H)曲线分别表现出铁磁性、超顺磁性及顺磁性的特征,表明SrNdCoO4陶瓷在200K附近发生顺磁-铁磁相变,引起磁化强度的迅速增大;在20K附近的磁化强度迅速增大也可从相应温度的M-H曲线特征得到解释.此外 ...

Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing
ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...
