Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Lithium metal anode and zinc metal anode have attracted considerable attention owing to their high theoretical capacity, low electrochemical potential, and superior electronic conductivity. However, their practical applications are greatly hindered by inherent issues such as uncontrollable dendritic growth and interfacial instability ...

Sexo é maldição, ódio é amor [PDF]
Revista Latinoamericana de Psicopatologia Fundamental, 2015 e o amor. Porem nao se trata do amor idealizado, mas sim daquilo que ele comporta de paradoxal, da sua face maldita, obscena e tragica. E no estudo das obras literarias de Nelson Rodrigues, Gregorio de Matos e Fernando Pessoa que este livro demonstra a afirmacao freudiana de que os artistas ja sabiam o que mais tarde a psicana-lise veio revelar: a ...

Shuitu Baochi Xuebao, 2018 通过水稻威优46盆栽种植试验，研究了外源Zn施用（0，40，80，160 mg/kg 4个水平）对Cd中度（0.72 mg/kg）和重度（5.26 mg/kg）污染土壤中Cd生物有效性及水稻Cd累积的差异。结果表明：施Zn对各检测指标存在影响，但土壤Cd总量仍是土壤Cd活性和水稻Cd累积差异变动的主控因素。在Cd中度污染土壤中，施Zn降低了土壤交换态Cd含量1.9%~17.0%，但水稻根表铁膜、根和糙米中Cd含量随Zn施用浓度的增大而增大，糙米Cd含量从0.09 mg/kg上升到0.17 mg/kg ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Shuitu Baochi Xuebao, 2006 采用室内模拟降雨淋溶土柱的方法，研究了经过1年降雨的淋溶后，菜园土壤垂直方向上各形态锌的迁移转化规律。结果表明：锌的大多数形态很难随水分运动发生迁移，～年的降雨至多能使占总量0．57％的水溶态锌发生淋溶损失。水分淋洗和施磷锌平均能使分别占总量3％和4％的难溶态RES—Zn和OX-Zn向易被植物利用的EX—Zn、CABS—Zn和OM—Zn形态转化。随施锌量的增加，土壤锌的有效性指数增加30％～78％．有效锌总量增加3．12～10．07mg／kg。当施磷50mg／kg时，土壤Zn的有效性指数增加3％～28％，

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Biodegradable zinc (Zn)‐based materials are considered promising candidates for orthopedic applications because of their favorable mechanical properties, controllable biodegradability, and good biosafety profiles. However, their clinical translation is limited by early‐stage corrosion‐induced cytotoxicity and inflammation, as well as ...

Sociologias Plurais, 2012 Comumente, em referência a atletas de futebol, evoca-se uma masculinidade tradicional (BONINO, 2008), definida como modelo social hegemônico. No presente artigo, refletir-se-á sobre a chamada "área reservada masculina" (MAGUIRE & DUNNING, 1997), considerada como relevante à manutenção das estruturas patriarcais. A partir de coberturas jornalísticas
