Scalable Upcycling of Spent Lithium‐Ion Battery Anodic Graphite to Electronic‐Grade Graphene

open access: yesAdvanced Science, EarlyView.
Graphite anodes from spent lithium‐ion batteries are upcycled into electronic‐grade graphene nanoplatelets for highly conductive screen printing inks (> 104 S m−1). Screen‐printed micro‐supercapacitors confirm the utility of the upcycled graphene (1.78 mF/cm2 capacitance for > 10 000 cycles). Life cycle assessment and techno‐economic analysis highlight

Direct optical observation of walls and disclination effects in active photonic devices

open access: yes, 2009
Liquid crystal tunable Bragg Gratings defined in planar substrates via a laser patterning technique exhibit complex wavelength tuning. This tuning displays threshold points and hysteresis. These tuning features are shown to be a manifestation of physical

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Mixed‐Phase TiO2 Nanotubes Enhance Ru Nanoparticle Activity for Hydrogen Evolution in pH‐Neutral Electrolytes

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Efficient water electrolysis in NaBr electrolyte is achieved using TiO2 nanotube supports decorated with Ru nanoparticles. A cooperative “job‐sharing” effect between the TiO2 proton‐storage support that provides protons to the Ru catalyst enhances hydrogen evolution, minimizes Ru demand and polarization losses, and delivers stable performance ...

Unveiling Localized Heat in Lithium‐Ion Cells for Intelligent Temperature Sensing

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Heat generation, thermal responses, and intelligent management in batteries. Lithium‐ion batteries (LIBs) power electric vehicles, portable electronics, and grid‐scale storage, yet their safety, performance, and lifetime are constrained by thermal effects.
