In Situ Disentangling Local Thermal and Photoelectron Contribution in Photoelectrochemical Reactions Based on Optical Microfiber Sensors

Advanced Science, EarlyView.
An in situ optical microfiber sensor capable of real‐time decoupling of photothermal and photoelectronic effects in photoelectrochemical reactions is presented. The approach utilizes highly sensitive modal interference to dynamically capture localized thermo‐optic signals from photothermal materials, thereby enabling quantitative discrimination of ...

A Laminating Strategy to Manyfold Enhance the Elastic Stretchability of Stretchable Electronics

Advanced Science, EarlyView.
We propose a laminating strategy that laminates a thick‐polymer layer onto the thin‐ribbon metallic structure. Using serpentine structures on soft and hard substrates as representative cases, this approach increases elastic stretchability by 3.5‐fold and 2.3‐fold.

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Laser-induced damages to charge coupled devices with combined nanosecond/picosecond short-pulse lasers

Frontiers in Physics
The research on laser induced breakdown mechanism of charge coupled devices (CCDs) brings new insights into photoelectric countermeasures. So far combined laser irradiation has been proved to be a more effective measure to destroy CCD.

Ultrafast Electron Transfer Coupled with a Proton Relay in an Anisotropic Dual S‐Scheme Heterojunction for Overcoming Kinetics Mismatch in H2O2 Photosynthesis

Advanced Science, EarlyView.
An anisotropic dual S‐scheme heterojunction (C3N4/SubPc‐1/C3N5) is constructed to overcome the electron–proton kinetics mismatch in photocatalytic H2O2 production. The imide bridge serves as a dual channel for ultrafast electron transfer and proton relay, synergistically enabling efficient dual‐pathway oxygen reduction and achieving a high H2O2 ...

Association between irradiation parameters and outcomes for picosecond laser treatment of nevus of Ota: An in-silico-supported meta-analysis

JAAD Reviews
Background: Picosecond lasers are promising modalities for treating nevus of Ota. However, inconsistent outcomes and complication rates have hindered consensus on their clinical advantage.

Transient Terahertz Oscillations During Photoinduced Polarization Topology Reconfiguration in Ferroelectric Superlattices

Advanced Science, EarlyView.
Terahertz resonances in crystalline heterostructures could close a spectral gap between conventional electronics and photonics while opening new windows on non‐equilibrium lattice dynamics. Femtosecond optical screening of the depolarization field in epitaxial PbTiO3/SrTiO3 superlattices launches a collective polar mode that oscillates near 1 THz and ...

On‐Chip Silicon‐Based Micro‐Reflector Pixelated with Micro‐Light‐Emitting Diodes for Augmented Reality Projection Displays

Advanced Science, EarlyView.
This paper presents a pixel‐by‐pixel on‐chip silicon‐based micro‐reflector device (SMRD) for µLEDs that enables simultaneous light‐extraction enhancement and directional emission control. The scalable architecture significantly improves forward light utilization and suppresses pixel crosstalk.
