Targeting the KCNC3‐Dependent Anterior Insular‐Lateral Orbitofrontal Cortex Glutamatergic Circuit Attenuates Post‐Traumatic Anxiety

Advanced Science, EarlyView.
Frontal lobe traumatic brain injury is associated with hyperactivity of an insular–orbitofrontal circuit in both patients and mice. By combination of integrating functional imaging, cell‐type–specific circuit manipulation, single‐cell transcriptomics, and whole‐cell recordings, this work identifies the downregulation of the potassium channel KCNC3 in ...

Scalable MoS2/Si Photodiode Arrays From Roll‐to‐Roll Mechanical Exfoliation

Advanced Science, EarlyView.
A dry roll‐to‐roll route transforms mechanically exfoliated MoS2 flake networks into silicon‐integrated photodiode arrays. The MoS2/Si junctions generate photovoltaic output without applied bias, allowing illuminated pixels to locate light spots and reconstruct simple images.

Synergistic Effects in Multistate Black Electro‐Thermochromic Smart Windows for Energy‐Efficient Modulation of Solar Heating

Advanced Science, EarlyView.
Hybrid electro‐thermochromic smart windows are developed for dynamic climate control by integrating a redox‐matched black electrochromic gel with a paraffin‐based thermochromic film. This synergistic combination enables multimodal solar modulation, where photothermal heating from the electrochromic layer triggers thermochromic activation at lower ...
