Enhancing Bubble Removal in Geometry‐Optimized Electrodes

open access: yesAdvanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

Photon Recycling–Driven Photodetection Enhancement in Ni(AcO)2–MAPbBr3 Nanocomposite Waveguides

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
Photon recycling is demonstrated as an effective mechanism to enhance perovskite photodetector performance. A Ni(AcO)2/MAPbBr3 nanocomposite waveguide enables long‐range propagation and reabsorption of photoluminescence photons, increasing photocurrent by ∼60%. Under pulsed excitation, reabsorption of amplified spontaneous emission further enhances the

A Pressure Microsensor Made of Parylene‐C for Use as Medical Implant

open access: yesAdvanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
A monolithic parylene‐C pressure sensor with gold strain gauges provides 6.2 μV$\mu{\rm V}$·mmHg$\cdot{\rm mmHg}$−1$^{-1}$ sensitivity. The morphology of a sputtered thin film strain sensor is granular/columnar, which results in a high gauge factor of 7.5. Thermal bonding and parylene‐C coating create a hermetic cavity.

Recent Progress and Future Prospects of LWIR T2SL InAs/GaSb Detectors on GaAs

open access: yesAdvanced Photonics Research, Volume 7, Issue 7, July 2026.
InAs/GaSb LWIR type‐II superlattices (T2SLs) on GaAs substrates are cost‐effective and offer higher yield. However, due to a relatively large lattice mismatch, a high density of threading dislocations is created, which is detrimental to device performance.
