Bipolar photovoltaic effect in InSe/MoO3 van der Waals heterostructure for spontaneous light polarization detection

InfoMat, EarlyView.
Bidirectional photo response in a two‐dimensional heterojunction photodetector controlled by light wavelength and polarization. Abstract Polarization is one of the most fundamental properties of light. Traditional polarization‐sensitive photodetectors, however, are limited in their ability to fully extract this information, as they translate the two ...

Phase separation enables dual ionic and thermal transport in solid‐state cathodes

InfoMat, EarlyView.
We design a phase‐separated ionogel composite cathode (PS cathode) with a bicontinuous network formed through ionic liquid‐polymer phase separation. Simulations and experiments show that this architecture couples efficient ionic conduction with enhanced thermal transport, thereby suppressing polarization and hotspot formation.

Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

Journal of Raman Spectroscopy, EarlyView.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.

Reusable SERS Substrate Based on AuNP/PS‐b‐P2VP Nanocomposites With Photocatalytic Activity

Journal of Raman Spectroscopy, EarlyView.
We developed a bifunctional SERS substrate by assembling AuNPs on PS‐b‐P2VP thin films, capable of both sensitive molecular detection and UV‐assisted self‐cleaning. The platform demonstrates excellent reusability over four adsorption–degradation cycles, driven by a hot‐hole‐mediated photocatalytic mechanism without semiconductors.

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...
