Zwitterionic Polymer Coating Enabled Chronic Dopamine Sensing and Electrophysiology Recording in Free‐Moving Mice

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 37, 9 October 2026.
Application of a zwitterionic poly(sulfobetaine methacrylate) (PSB) coating to microelectrode arrays and Ag/AgCl reference electrodes effectively inhibits biofouling and structural degradation. This strategy successfully enables simultaneous, long‐term electrophysiological recording and dopamine sensing in freely behaving mice, facilitating ...

A Geometrically Transient Platform for Bioelectronic Implants

open access: yesAdvanced Materials, Volume 38, Issue 55, 1 October 2026.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Computational and Experimental Thermoelectric Properties of YCuSb2

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 10, October 2026.
The thermoelectric properties of the topological material YCuSb2 and its Te‐doped derivatives are investigated through a combination of experimental and computational methods. The materials exhibit low lattice thermal conductivity and electrical resistivity due to high carrier concentrations.

Effect of Damp Heat Aging on Solder Interconnection Reliability and Photoluminescence Degradation of Polycrystalline Silicon Solar Cells for Solar‐Powered UAV Applications

open access: yesApplied Research, Volume 5, Issue 5, October 2026.
Damp heat aging degraded both solder interconnections and silicon solar cells, leading to increased electrical resistance and reduced photoluminescence intensity. Among the solder alloys evaluated, SnAgCu exhibited the most stable electrical performance, making it a promising candidate for improving the long‐term reliability of solar‐powered UAVs ...

The Fiery Eyes of a Maenad: Origin Determination of Faceted Garnet Eye Inlays in a Roman Bronze Bust From Southern Tyrol

open access: yesArchaeometry, Volume 68, Issue 5, Page 898-907, October 2026.
ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as
