Circular Potential of Lithium‐Ion Battery Recycling Slags: Quantifying Microstructure and Elemental Distribution for a Holistic Valorization

open access: yesAdvanced Science, EarlyView.
A lithium‐bearing slag is investigated with the goal of holistic valorization. The present β‐eucryptite (LiAlSiO4) exhibits a high lithium content and low levels of impurities. The spinel contains most of the chromium and vanadium, representing additional valorization opportunities.

The Neumann function and the L p Neumann problem in chord-arc domains

open access: yesAdvanced Nonlinear Studies
We construct the Neumann function in a 1-sided chord-arc domain (i.e., a uniform domain with an Ahlfors regular boundary), and establish size and Hölder continuity estimates up to the boundary.

Multi‐Physical Field Modulated P‐Bit Device Based on VO2 Thin Film

open access: yesAdvanced Science, EarlyView.
We have proposed a VO2‐based P‐bit device where synergistic multi‐physical field modulation enables real‐time tunability of randomness. Besides introducing a new phase‐change material‐based device approach for high‐performance P‐bits, this study also demonstrates a synergistic multi‐physical field modulation strategy that opens new opportunities for ...

The Initial and Neumann Boundary Value Problem for a Class Parabolic Monge-Ampère Equation

open access: yesAbstract and Applied Analysis, 2013
We consider the existence, uniqueness, and asymptotic behavior of a classical solution to the initial and Neumann boundary value problem for a class nonlinear parabolic equation of Monge-Ampère type. We show that such solution exists for all times and is
