Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

open access: yescMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Sandwich Miura‐Ori Enabled Large Area, Super Resolution Tactile Skin for Human–Machine Interactions

open access: yesAdvanced Science, Volume 12, Issue 18, May 15, 2025.
Sandwich Miura‐ori based tactile skin achieves large area sensing and super resolution, due to the interactions between different cells. It can also decouple external loads because of the special deformation mechanism. The curved tactile skin can be installed on robotic arms and achieve straightforward control and interactions, showing its great ...
