Critical Metals Hydrometallurgy [PDF]
JOM, 2015 In 2013, the E.U. Ad hoc Working Group on Raw Materials published its second criticality analysis report. The motivation to write this report came from the observation that in today’s world, our economies become more and more dependent on a number of metals and raw materials. Achzet et al.

BCS superconductivity in quantum critical metals [PDF]
Physical Review B, 2009 Departing from the assumption that pairing is induced by an retarded external 'bosonic glue', we reformulate the Bardeen-Cooper-Schrieffer theory of superconductivity as a scaling theory. Conventional superconductors correspond with the asymptotically free case but the theory can be effortlessly generalized to handle quantum critical metals.

Crystals, 2023 In this paper, the effects and the mechanisms of melt superheating treatment (MST) on a directionally solidified alloy were investigated. The mass loss rate of the superalloy becomes severe as the MST temperature rises.

Quantum criticality in heavy-fermion metals [PDF]
Nature Physics, 2008 Quantum criticality describes the collective fluctuations of matter undergoing a second-order phase transition at zero temperature. Heavy fermion metals have in recent years emerged as prototypical systems to study quantum critical points. There have been considerable efforts, both experimental and theoretical, which use these magnetic systems to ...

Responsible Sourcing of Critical Metals [PDF]
Elements, 2017 Most critical raw materials, such as the rare-earth elements (REEs), are starting products in long manufacturing supply chains. Unlike most consumers, geoscientists can become involved in responsible sourcing, including best environmental and social practices, because geology is related to environmental impact factors such as energy requirements ...

Comparative Studies of Digestion Techniques for the Dissolution of Neodymium-Based Magnets
Metals, 2021 The digestion of neodymium (NdFeB) magnets was investigated in the context of recycling rare earth elements (i.e., Nd, Pr, Dy, and Tb). Among more conventional digestion techniques (microwave digestion, open vessel digestion, and alkaline fusion ...
