Achieving Ambient‐Temperature Fast Hydrogenation Properties in Ga‐Doped Mg–Ni Alloy: Dual‐Phase Synergistic Catalysis and Stacking Fault Channels

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The high operating temperatures and sluggish kinetics of Mg‐based hydrogen storage materials (HSMs) are urgently being addressed. In this work, a novel Mg–Ni–Ga HSM with dual‐phase synergistic catalysis is developed, including the fishbone‐like Mg3Ni2Ga1 catalytic phase and the Mg2Ni phase with stacking faults (SFs).

SE É FUTEBOL, É MASCULINO?

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

"A culpa é sua" [PDF]

Psicologia USP, 2006
O artigo analisa a influência das concepções tradicionais da Psicologia nas falas de educadores e alunos sobre o fracasso escolar na atualidade. Para tanto, faz uma breve revisão da psicometria e da teoria da carência cultural como representantes da concepção ideológica que centra no indivíduo e no "ambiente" as causas do fracasso.

Comparative Evaluation of Chemical and Physical Expansive Agents in Cemented Paste Backfill: Expansion Behavior, Mechanical Response, and Microstructural Mechanisms

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT This study presents an assessment of four representative expansive additives—calcium sulphoaluminate–calcium oxide, magnesium oxide, sodium lauryl sulfate, and sodium abietate—and their effects on the expansion behavior, mechanical development, and microstructural characteristics of cemented paste backfill (CPB).

Interface Issues of Inorganic Solid‐State Electrolytes in Secondary Magnesium Batteries

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Solid‐state magnesium batteries (SSMBs) have gained significant attention as promising candidates for next‐generation safe energy storage systems because of the abundance of magnesium (Mg) in the earth's crust, superior energy density, and inherent nonflammability.

电解熔融砂晶盐制金属镁的试验报告

四川大学学报. 自然科学版, 1959
四川盐卤中含有大量的氯化镁,每年约有数千近一万吨没有利用起来。因此;利用盐卤中的氯化镁制金属镁就成为盐卤综合利用的重要项目之一。我组应用自贡化工厂用盐卤提制硼、钾过程中的中间产品——砂晶盐作原料,进行了脱水和电解制镁试验。砂晶盐的主要成分是水合氯化镁和氯化钾,近似光卤石的组成。经脱水电解制镁后,尚能利用电解液提制氯化钾。

A pobreza é coercitiva?

Novos Estudos - CEBRAP, 2021
O objetivo deste artigo é argumentar que situações de privação material são inerentemente coercitivas. Para isso, avaliam-se teorias da justiça para as quais a pobreza não representaria uma forma de intervenção coercitiva em contextos de livre-mercado. Argumenta-se aqui que a pobreza precisa ser concebida como uma posição social subordinada e, portanto,
