Steady‐State and Dynamic Behavior of Geometry‐Tunable Microfluidic Passive Flow Regulators

Small, EarlyView.
Passive microfluidic flow regulators exhibit geometry‐dependent dynamic behavior, where channel width governs the resistance–compliance interactions within the system. Narrow channels produce faster responses with higher bandwidth, while wider channels yield slower responses and stronger attenuation.

Near‐Atomic Investigation on the Elemental Redistribution During Coprecipitation of Nano‐Sized Kappa‐Type and B2 Precipitates in an Al‐Alloyed Lightweight Steel

steel research international, EarlyView.
Elemental redistribution during coprecipitation of kappa (κ)‐type and B2 precipitates in an Al‐alloyed lightweight steel is revealed by atom probe tomography (APT) and density functional theory (DFT). Fe and Ni redistribution promotes the evolution of B2 phase from NiAl‐type toward FeAl‐type and improves the stability of κ and B2 phases during ...

Out-of-time-ordered-correlators for the pure inverted quartic oscillator: classical chaos meets quantum stability

Journal of High Energy Physics
Out-of-time-ordered-correlators (OTOCs) have been suggested as a means to diagnose chaotic behavior in quantum mechanical systems. Recently, it was found that OTOCs display exponential growth for the inverted quantum harmonic oscillator, mirroring the ...

Photochemistry of CryB from Rhodobacter sphaeroides

Photochemistry and Photobiology, EarlyView.
Elucidation of the photochemistry of CryB from Rhodobacter sphaeroides was achieved from the nanosecond to second timescale. A fast (<5 ns) deprotonation of the terminal electron donor Trp338 and the involvement of Tyr337 in photoreduction have been revealed.

Data‐ and Theory‐Guided Design of Dual‐Role V‐Doped RuO2 for High‐Performance Acidic Oxygen Evolution

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
A data‐ and theory‐guided paradigm, leveraging large‐scale data mining of 718 catalysts and microkinetic modeling, identifies V‐doped RuO2 as optimal for acidic OER. Vanadium doping drives electron withdrawal from Ru centers, generating Lewis acidic sites that polarize O–H bonds and accelerate deprotonation kinetics. Experimental validation achieves an
