Experimental validation of a fluid dynamics based model of the UF Falcon concentrator in the ultrafine range [PDF]

, 2012
The process of separating ultrafine particles, say below 80 μm, on the basis of density is a true technical challenge. Indeed, the separation process itself becomes very much size dependent with such fine particles, so that large enough density ...

Ultra–Efficient and Selective Gold Separation via Second–Sphere Coordination of Aurous Dihalide Using a Nonporous Amorphous Superadsorbent

Advanced Science, EarlyView.
A covalent organic superphane cage serves as a nonporous amorphous superadsorbent for highly efficient and selective gold separation. This material uniquely captures linear aurous dihalide ions, achieving exceptional uptake capacity and selectivity, and proving effective even in seawater, offering a scalable, eco–friendly solution to gold scarcity ...

Deep‐sea nodules versus land ores: A comparative systems analysis of mining and processing wastes for battery‐metal supply chains

Journal of Industrial Ecology, Volume 26, Issue 6, Page 2154-2177, December 2022., 2022
Abstract To meet UN Sustainable Development goals, a clean‐energy transition with minimal ecological impact from its raw‐material supply chain is essential. Polymetallic nodules lying unattached on the abyssal seafloor of the Pacific Ocean's Clarion Clipperton Zone contain four critical metals (nickel, cobalt, manganese, copper) in large quantities ...

Phase and mechanical property prediction of intermetallic-strengthening Ti-Al-Cr-Nb-Ni-Cu-Co high entropy alloys by thermo-physical parametric calculation and CALPHAD-based technique [PDF]

MATEC Web of Conferences
Non-conventional alloy developmental approach targeted at incorporating intermetallics as strengtheners using thermo-physical parametric calculation and CALPHAD-based tool (ThermoCalc software) were adopted in the design of septenary non-equiatomic ...

Microstructural Evaluation of Inconel 718 and AISI 304L Dissimilar TIG Joints

Metals, 2023
Dissimilar welding joints of Inconel 718 (IN718) nickel superalloy with low-carbon AISI 304L austenitic steel (SS304L) were conducted using the Tungsten Inert Gas (TIG) welding process. The present investigation focuses on the effect of different welding

Oxygen Doping in Ferroelectric Wurtzite‐type Al0.73Sc0.27N: Improved Leakage and Polarity Control

Advanced Electronic Materials, EarlyView.
Left: Polarization hysteresis (P‐E) characteristics of 200 nm wurtzite‐type Al0.73Sc0.27N without (ref. Nmix = 0) and with O‐doping (Nmix = 8 and 15), showing a clear drop of leakage current with O‐doping. Right: Piezoresponse for microscopy showing the as‐deposited polarization reversal from nitrogen (Nmix = 0) to metal polarity (Nmix = 15) via mixed ...

Abandoned mine land program: Examining public participation in decision‐making

Review of Policy Research, EarlyView., 2023
Abstract For centuries, coal extraction and production provided low‐cost energy that powered the American economy. Currently, an estimated 5.5 million people in the Appalachian region live within one mile of an Abandoned Mine Land (AML) site. The site remediation has been funded and promoted by the AML program under the Surface Mining Control and ...

Theoretical study on corrosion behaviour of titanium metal alloyed with precious metals [PDF]

MATEC Web of Conferences
This study investigated the role of valence electron orbital filling ( e/a ratio) on the reported corrosion resistance performance of Ti-Pt and Ti- Au binary alloys containing less than 10 atomic percent (at. %) precious metal.

A common framework for aspect mining based on crosscutting concern sorts [PDF]

Proceedings Working Conference on Reverse Engineering (WCRE), IEEE Computer Society, 2006, pages 29-38, 2006
The increasing number of aspect mining techniques proposed in literature calls for a methodological way of comparing and combining them in order to assess, and improve on, their quality. This paper addresses this situation by proposing a common framework based on crosscutting concern sorts which allows for consistent assessment, comparison and ...

Pretreatment and Valorization of Critical Materials from Lithium‐Ion Batteries Using Electrostatic and Magnetic Separation

Advanced Energy and Sustainability Research, EarlyView.
This study investigates how magnetic and electrostatic separation processes can be applied to coarsely shredded Li‐ion batteries to effectively recover high‐purity concentrates of shredded cathode electrode, shredded anode electrode, and shredded separator.
