3D Printed High‐Strength Hydrogel for Dual Release of Cu2+ and Ag+ Ions to Enhance Bone Repair and Antibacterial Properties

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Regulating Vacancy Formation Energy and Interface Reaction to Achieve Excellent Mechanical and Tribological Properties of Cu/WS2 Composite Alloying With Sn

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Achieving a simultaneous enhancement in both tribological and mechanical properties of self‐lubricating composites has long been a challenge. In this study, we designed the composition based on first‐principles calculation and fabricated a copper‐based self‐lubricating composite with excellent tribological and mechanical properties via spark ...

铜在土壤中的淋溶迁移特征研究

open access: yesShuitu Baochi Xuebao, 2007
以棕壤为供试土壤,采用室内土柱淋溶模拟试验方法,研究了相当于泰安平均年降水量条件下铜在土壤垂直方向上的迁移转化特征.结果表明:各处理土壤中的铜在0~10 cm土层中均有不同程度的迁移转化.土壤铜含量越高,年降水量条件下表层土壤中铜的淋失量越大,沉淀态铜和矿物残留态铜所占的比例增加了28.57%~33.49%.高铜土壤中,钙含量的增加使交换态铜比例降低幅度为9.97%~10.48%,使铜的迁移量最大可减少15.54%;随褐煤施入量的增加,表层交换态铜含量减少,铜向5~10 cm土层中的淋溶量减少显著 ...

Interfacial Engineering of Sodiophilic Metal Layers on Liquid Alloys for Dendrite‐Free Sodium Metal Anodes

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Sodium metal batteries hold significant promise for large‐scale energy storage due to the high theoretical capacity and abundant sodium sources, yet sodium‐metal anodes are hindered by dendrite propagation, unstable solid electrolyte interphase, and poor cycling efficiency arising from uneven Na deposition and volume changes.

SE PUBLICAR É PRECISO, AVALIAR TAMBÉM É! [PDF]

open access: yesRevista de Administração de Empresas, 2018
O tema “revisão de artigos” é relevante e faz parte do cotidiano de todo pesquisador. Entretanto, a minha experiência como editor e revisor em periódicos brasileiros e internacionais torna evidente que o comprometimento dos pesquisadores na função de revisores, em geral, é muito menor do que quando estão na posição de autores.
