Metal‐Doped Carbon‐Based Nanomaterials: Photothermal Mechanism Innovation and Precision Therapy Advancement in Antibacterial and Antitumor Applications

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by

Complexion‐Mediated Dislocation Transfer Enables Exceptional Strength‐Toughness Synergy in Multicomponent‐Alloy Bonded Hardmetal

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The inherent brittleness of hardmetals stems from the rigid covalent bond in the ceramic matrix and the sharp ceramic/metal interface, which restricts the nucleation and motion of dislocations. In this study, a novel strategy is proposed to activate significant dislocation behaviors in the WC matrix by employing a non‐equiatomic CoNiFeCr ...

Simultaneous Enhancement of Strength–Ductility and Heat Resistance in Al‐Cu‐Mn Alloys Through Sn‐Mediated Precipitation and Ni/Ca‐Induced Grain‐Boundary Engineering

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Giga‐casting, a near‐net‐shape manufacturing process widely used in sectors such as new energy vehicles and aerospace, demands aluminum alloys with high integration, efficiency, and comprehensive performance. However, traditional die‐cast alloys still face two core bottlenecks: the strength–ductility trade‐off and high‐temperature ...

两种不同有限元模型的拉索弯曲性能

open access: yesJianzhu Gangjiegou Jinzhan, 2019
由于拉索内部的力学性能比较复杂,采用有限元方法进行拉索分析。对于钢绞线的有限元模型,目前多采用Solid164单元来进行建模,而对于半平行钢丝束拉索的有限元模型,目前多采用Pipe16单元来进行建模。该模型的特点是由短梁单元和弹簧单元组成。分别采用Pipe16单元和Solid164单元来建立拉索模型,分析了两种有限元模型的弯曲荷载-挠度曲线和拉索的有效弯曲刚度,并与试验数据进行了对比分析。结果表明,对于无预应力条件下,Pipe16单元的模型结果与试验数值误差比Solid164模型的要大 ...

Topics as Outcomes: Modeling the Influence of Intergovernmental Grants on Policy Diffusion

open access: yesPolicy Studies Journal, Volume 54, Issue 2, May 2026.
ABSTRACT Intergovernmental grants stimulate the diffusion of policy reforms, as the federal government provides states with a financial incentive to adopt policies aligned with federal priorities. Less is known about the extent to which these grants also stimulate horizontal diffusion across states.
