Hyperbranched Molecular Brush Membrane for Efficient and Antifouling Oil‐Water Emulsion Separation

open access: yesCleanMat, EarlyView.
This work develops a carboxyl‐terminated hyperbranched molecular brush‐modified membrane that exhibits superhydrophilicity, underwater superoleophobicity, and a strong negative charge. The membrane achieves high efficiency, superior antifouling performance, and stable separation of oil‐in‐water emulsions across a wide pH range.

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

open access: yesDeep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels

open access: yesEnergy Science &Engineering, EarlyView.
A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents

Flexible Multi‐Mode Electrochromic Displays for Human Motion Monitoring and Pattern Display in Dark Environments

open access: yesExploration, EarlyView.
The reflective nature of electrochromic displays limits their display functionality and human motion monitoring in dark environments. This work presents a flexible multi‐mode electrochromic display (FMECD) with high optical modulation (75.8%) and low energy consumption (0.004% of OLEDs). Integrating EC, PL, and ML functions, it enables continuous, real‐
