High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

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,

ABSTRACT The pre‐existing α‐Fe crystals have important effects on the precipitation and growth of nanocrystals and finally determine the comprehensive soft magnetic properties (SMPs) of the nanocrystalline alloys (NAs). In this work, a high content of Cu elements has been added to Nanomet‐type alloys to enhance the gradient heterogeneity in order to ...

Sexo é maldição, ódio é amor [PDF]
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 ...

Cu‐Based Catalysts Design Toward Electrochemical CO2 Reduction to Valuable Multi‐Carbons Products
ABSTRACT Electrochemical reduction of CO2 to multi‐carbon products (e.g., C2+, ethene, ethanol, etc.) not only effectively decreases the CO2 concentration in atmosphere but also shows great potential economic benefits due to these exploitable value‐added products. The Cu‐based catalysts have caught much attention in CO2 electroreduction due to the good

Direct Observation of Matrix‐to‐Precipitate Elemental Diffusion in Severe Plastic Deformation
ABSTRACT Elemental redistribution, particularly the solute exchange between the matrix and precipitates, is a central issue in alloys subjected to severe plastic deformation (SPD). To elucidate this behavior, a nickel–aluminum bronze (NAB) alloy was processed by high‐pressure torsion (HPT), and its microstructural evolution was systematically ...
