Assessing the Criticality of Metals [PDF]
, 2013 Today’s technology employs virtually the entire periodic table. The stocks and flows of the major metals, essentially unknown a decade ago, are now reasonably well quantified. Those cycles can be used to generate on overview of societal metal use. A key issue is whether scarcity implies long-term shortages or unavailability.

Critical Fidelity at the Metal-Insulator Transition [PDF]
Physical Review Letters, 2006 Using a Wigner Lorentzian random matrix ensemble, we study the fidelity, F(t), of systems at the Anderson metal-insulator transition, subject to small perturbations that preserve the criticality. We find that there are three decay regimes as perturbation strength increases: the first two are associated with a Gaussian and an exponential decay ...

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.

Quantum criticality in twisted transition metal dichalcogenides [PDF]
Nature, 2021 Abstract In moiré heterostructures, gate-tunable insulating phases driven by electronic correlations have been recently discovered. Here, we use transport measurements to characterize the gate-driven metal-insulator transitions and the metallic phase in twisted WSe2 near half filling of the first moiré subband.

The Use of Critical Solution Mixtures for Contaminated Sediments Remediation [PDF]
, 2007 Using a critical solution mixture, into which chelating agents have been dissolved, resulted in the efficient, rapid and simultaneous removal of both heavy metals and organic pollutants from contaminated sediments.

International Journal of Mining Science and TechnologyThe microfine ilmenite generated during ilmenite beneficiation is challenging to separate from gangue. As a result, it is often discarded directly into tailings, causing wastage of titanium resources.
