Highly Conductive and Transparent Coatings via Low‐Temperature Hydroiodic Acid Vapor Treatment of Oxo‐Graphene Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
The double self‐assembly (DSA) method applied to oxo‐graphene (oxo‐G) flakes followed by hydroiodic acid (HI) vapor treatment and low‐temperature annealing yields highly conductive, optically transparent thin films with the potential for applications in electronic and optoelectronic devices.

A Human Bone Defect‐on‐a‐Chip Model for Studying Bone Regeneration

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a novel human bone defect‐on‐a‐chip (BDOC) model, aiming to recapitulate key processes during early bone healing, incorporating bone graft substitutes. Over 21 days, human mesenchymal stem/stromal cells (HMSCs) and human primary macrophages are co‐cultured in the BDOC together with calcium phosphate microparticles.

Terahertz Phase Inversion via Field‐Free Spin‐Orbit Torque Switching in an Antenna‐Integrated Spintronic Heterostructure

open access: yesAdvanced Optical Materials, EarlyView.
This work demonstrates fast electrical control of the phase of broadband terahertz pulses using a field‐free spintronic emitter. An antenna‐integrated Ta/CoFeB/Pt heterostructure switches its magnetization through spin‐orbit torque with 1 μs$\umu{\rm s}$ electrical pulses, producing complete π$\pi$‐phase inversion without external magnetic fields ...

Exploring the Pressure – Temperature Phase Diagram of InAs Quantum Dots

open access: yesAdvanced Optical Materials, EarlyView.
The pressure‐temperature phase diagram of InAs nanocrystals reveals a stable zinc‐blende structure up to 12 GPa, with a 50 meV/GPa band gap shift. Cooling induces a blue shift, narrowing the spectral window, while quantum confinement tunes temperature and pressure dependencies—critical insights for SWIR sensing applications. ABSTRACT III–V nanocrystals
