Sticker Valence Governs Chain Collapse and Liquid‐Liquid Phase Separation in Peptide‐Inspired Associative Polymers

open access: yesAdvanced Science, EarlyView.
Peptide‐inspired associative polymers with arginine‐like guanidinium stickers and lysine‐like ammonium spacers undergo chain collapse and liquid‐liquid phase separation induced by reversible sticker associations. Sticker valence and tunable association strength jointly control the phase behavior, chain conformation, and interfacial cohesion of these ...

The acoustic wave generation by a thin layer with variable temperature

open access: yesArchives of Acoustics, 2015
This study considers the problem of the thermal sound generation in the air by an unmoving solid body with a time-variable temperature. Applying the linear relations between the thermal energy stream supplied to a thin layer of a solid body in touch with

Efficient Cholesteric Liquid Crystal Waveguide Polarizing Splitters for High‐Sensitivity Chip‐Scale Atomic Magnetometry

open access: yesAdvanced Science, EarlyView.
An integrated polarimetry architecture based on a cholesteric liquid crystal waveguide polarization splitter overcomes the volumetric bottleneck in chip‐scale atomic magnetometers. By leveraging Bragg‐selective reflection and total‐internal‐reflection‐induced helicity inversion, this ultrathin device enables efficient circular polarization splitting ...

Magnetic Water Cleaning of Estrogens via Tight yet Dynamic Binding to Nanoparticles

open access: yesAdvanced Science, EarlyView.
Micropollution is one of the big challenges humanity faces with estrogen hormones being emerging pollutants of concern. Here, a supramolecular design strategy is presented that generates a simple nano‐adsorbent material to magnetically remove low‐concentrated estrogens from water.

Bridging Horizontal to Vertical Radiative Cooling

open access: yesAdvanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Plasma‐Engineered Polyethylene‐Reinforced Anion Exchange Membranes With Low Ionic Resistance and Low Hydrogen Crossover for Water Electrolysis

open access: yesAdvanced Science, EarlyView.
Oxygen plasma functionalizes porous polyethylene, enabling complete hydrocarbon ionomer infiltration within a dense submicron pore network. The resulting reinforced composite membrane simultaneously enhances mechanical robustness and suppresses hydrogen permeation at ultrathin thickness. An integrated performance index confirms the effectiveness of the

Assessment of the thermal transmittance in ventilated windows

open access: yes, 2014
The aim of this paper is to analyze the performance of thermal transmittance of a dynamic glazing system in the real conditions of work. The thermal transmittance of an envelope component, opaque or transparent, is not a constant physical quantity but it
