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

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator
This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.

Bio‐Inspired, Zwitterionic Copolymers with Amphiphilic Character
Zwitterionic copolymers based on arginine‐derived monomers are produced by xanthate‐supported photo‐iniferter reversible‐addition‐fragmentation chain‐transfer polymerization. Experiments in relevant conditions show that the designed (co)polymers hardly interact with biologically relevant proteins and enzymes such as bovine serum albumine (BSA), fetal ...

Electrically Tunable Tunneling and Spectral Response in WSe2/h‐BN/CdSe/Graphene Heterostructure
In the WSe2/h‐BN/CdSe quantum dot/graphene heterostructure, the graphene voltage dynamically tunes the tunneling barrier and energy alignment across the h‐BN layer. The bias‐dependent Fermi‐level alignment enhances the tunneling density of states, leading to efficient extraction of photo‐excited electrons from QDs into WSe2 and graphene.

Alternative Post-Processing on a CMOS Chip to Fabricate a Planar Microelectrode Array
We present an alternative post-processing on a CMOS chip to release a planar microelectrode array (pMEA) integrated with its signal readout circuit, which can be used for monitoring the neuronal activity of vestibular ganglion neurons in newborn Wistar ...

Abstract Large uncertainties exist for future westward Saharan dust transport with increasing Greenhouse Gas emissions. We evaluate future changes in westward dust transport at the longitude of 18.6°W and a latitude range of 4°N–30°N using the Weather Research and Forecasting Model (WRF) with the GOCART dust module for the present‐day, with ERA‐Interim
