Coupled Ferroelectric–Photoelectrochemical in Water Reduction Over BiFeO3 Thin Film Heterostructure Modulated by Rare‐Earth Doping

open access: yesAdvanced Functional Materials, EarlyView.
Gd‐doped BFO (BGFO) exhibits a ∼2‐order reduction in leakage current owing to its lowest content of oxygen vacancies. This leads to a ∼2.5‐fold increase in remnant polarization. These improvements in BGFO effectively boost charge separation and transportation, resulting in the greatest incident photon‐to‐current efficiency of 12.9 ± 0.73% and a ∼1.5 ...

Room‐Temperature, High‐Resolution Soft Anisotropic Conductive Film for Electrical Interfacing in Stretchable Electronics

open access: yesAdvanced Functional Materials, EarlyView.
A UV‐crosslinkable soft anisotropic conductive film (ACF) provides high‐resolution, room‐temperature electrical interfacing. Upon UV exposure, azide crosslinkers within the ACF matrix form covalent bonds with a wide range of C–H‐containing materials, resulting in interfaces that are both mechanically durable and electrically reliable.

Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

open access: yesAdvanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

A Scalable, Durable, Fire‐Safe All‐Day Passive Radiative Cooling Coating for Sustainable Buildings

open access: yesAdvanced Functional Materials, EarlyView.
This study reports a scalable, durable coating that combines a fire‑retardant copolymer adhesive, hollow glass microspheres, and boron oxide to achieve passive radiative cooling with over 94% solar reflectance and >95% mid‑infrared emissivity. The coating maintains performance after UV and rain exposure and exhibits UL‑94 V‑0 fire resistance, enabling ...

Bistable Photochromic Guest–Host Liquid Crystals for Rewritable and Switchable Photonic Devices

open access: yesAdvanced Functional Materials, EarlyView.
A photochromic DTCP‐based liquid crystal dye is incorporated into cholesteric liquid crystals (CLCs) to achieve optically and electrically tunable multistable states. In the open‐ring form, the system exhibits three electrically stable textures—planar, focal conic, and uniformly lying helix (ULH)—corresponding to reflective, scattering, and transparent

Generative Adversarial Estimation of Channel Covariance in Vehicular Millimeter Wave Systems

open access: yes, 2018
Enabling highly-mobile millimeter wave (mmWave) systems is challenging because of the huge training overhead associated with acquiring the channel knowledge or designing the narrow beams.
