Battery Electrode and Materials Recycling by Rapid High-temperature Heating
Challenge
Recycling end-of-life Lithium-ion batteries (LIB) for second use applications is an effective strategy to secure the supply chain of battery materials. Current commercial LIB recycling methods, including hydrometallurgical and pyrometallurgical processes, primarily aim to recover the valuable metals such as Li, Co, Ni, and Mn from the...

An Assistive Robotic Exoskeleton Glove Designed for Patients with
Brachial Plexus Injuries
THE CHALLENGE
Exoskeleton gloves have proven to be invaluable in post-surgery therapy for patients with Brachial Plexus Injuries, countering hand muscle atrophy through controlled and assisted movements. While many rehab gloves target stroke recovery, they lack the desired Human-Machine Interface and struggle to find the right balance between performance...

Planar Bridging-Droplet Thermal Diodes
THE CHALLENGE
Thermal diodes preferentially conduct heat in one direction but insulate in the reverse direction. They are of immense practical interest for smart thermal management of aircraft, electronics, and buildings. However, real-life implementation has been constrained by poor effectiveness (solid-state diodes), dependence on a gravitational...
