Nanoconfinement‐Steered Molecular Preorganization Enables Efficient Monoethanolamine Degradation through Electronically Modulated High‐Valent Iron–Oxo Pathways

open access: yesAdvanced Science, EarlyView.
Precise modulation of reaction pathways remains an unresolved challenge in peroxymonosulfate‐activated advanced oxidation processes. The spatial preorganization strategy in engineered confinement architecture enables regioselective bond cleavage in monoethanolamine via synergistic proton–electron transfer, redirecting its degradation from nonselective ...

A Closed‐Loop‐Capable Neural Interface Platform for Deep Brain Modulation via Integrated Non‐Viral Gene Delivery, NIR Optogenetics, and Electrophysiological Recording

open access: yesAdvanced Science, EarlyView.
A multifunctional, 3D porous neural interface combines non‐viral gene delivery and NIR optogenetics to enable minimally invasive, closed‐loop modulation of deep‐brain circuits. Abstract Closed‐loop neuromodulation requires precise, stable, and cell‐specific control of neural circuits with minimal invasiveness.

Bio‐Based Wax Interfaces for Droplet Energy Harvesting at Fluoropolymer‐Like Output Levels

open access: yesAdvanced Science, EarlyView.
Replacing unsustainable fluorinated polymers in droplet‐based energy harvesters is usually limited by low power outputs, but carefully selected bio‐based polymers are capable of creating fluoropolymer‐like voltage outputs. Abstract Droplet impact and rebound on solid surfaces has emerged as a promising method for energy harvesting, typically ...

Ultrafast Laser‐Induced Interatomic Forces in Magnetostrictive Metals

open access: yesAdvanced Science, EarlyView.
This study reports ultrafast changes in the interatomic forces generated by femtosecond laser excitation in magnetostrictive FeGa thin films. This ultrafast process manifests as an optical birefringence signal lasting ≈400 fs. Using a pump‐probe system, the femtosecond evolution of this nonequilibrium interatomic interaction is visualized, providing ...

The influence of a local wall deformation on the development of natural instabilities in a laminar boundary layer [PDF]

open access: yes
The natural instabilities which propagate in the laminar boundary layer of a flat plate composed of intermittent wave trains are described. A spectral analysis determines the frequency range and gives a frequency and the harmonic 2 only if there is a ...
