Broadband Coherent Raman Scattering Spectroscopy at 50,000,000 Spectra per Second

Ultrafast Science
Raman scattering spectroscopy is widely used as an analytical technique in various fields, but its measurement process tends to be slow due to the low scattering cross-section.

Hopping‐Mediated Zero‐Bias Photocharge Retention in Solution‐Processed Van Der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Liquid–liquid interface assembly enables the fabrication of solution‐processed MoS2 and WSe2 centimeter‐scale, nanometer‐thick type‐II heterostructures on paper. Interfacial charge separation and hopping‐limited recombination produce rectification and persistent photocharge retention at zero bias.

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

Advanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Nano Borophene as a Programmable 2D Scaffold for Organized DNA Assembly and Long‐Range Energy Transfer

Advanced Functional Materials, EarlyView.
Borophene is introduced as a programmable 2D bio‐interface that organizes DNA through dual boron–sulfur and nucleobase interactions. This molecular architecture enables efficient long‐range nanosurface energy transfer, establishing new design principles for functional nano–bio interfaces and amplification‐free optical biosensing.

Probing methane in Uranus’ upper stratosphere using HST observations of the 1280 Å Raman feature

Astronomy & Astrophysics
We analysed far-ultraviolet (FUV) spectra of Uranus obtained by the HST STIS and COS instruments in 2012 and 2014, respectively, to determine the brightness of Raman-scattered Lyman-alpha (Lyα) emissions centred at 1280 Å (hereafter, the Raman feature ...

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...
