A hydrogen‐bubble repellent conjugated polymeric coating improves an electrochemical hydrogen evolution reaction maintaining a lower overpotential, a highly electrochemically active surface area and smaller Tafel slope. While the hydrogen‐bubble repellence because of polyglycerol moiety ensures an early detachment of produced hydrogen gas bubbles, the ...

Underwater seismometer validation
This work verifies and validates the calibration in a marine geophone by means of a hyperbaric chamber before and after the pressure underwater laboratory test. The objective is to characterise the transfer function according to the frequency of coupling between the geophone and the sediment.

Selective Membrane for Non‐Aqueous Electrochemical Flow Cells
Sulfonated fixed charge functionalization is increased to improve the conductivity of a cation exchange membrane in a non‐aqueous electrochemical cell. Based on ex situ analyses, the material achieved the highest selectivity for this type of system to date.

Ambient‐dried composite aerogels integrating MOF‐303, TEMPO‐oxidized cellulose nanofibers (TOCNF), and hygroscopic salts enable high‐performance atmospheric water harvesting (AWH), achieving competitive uptake at both low and high humidity. Enhanced with a solar‐evaporation layer, these scalable aerogels support self‐sustained plant growth in a ...

A scalable nano‐/micro‐confinement strategy is developed, where polyacrylamide (PAM)‐LiCl hybrid desiccants are confined within hollow nanoparticles (HNPs) and assembled into raspberry‐like microbeads. The beads have a hydrogel‐rich core and an NP‐rich shell for fast absorption and desorption, releasing water 13.6 L kg⁻¹ day⁻¹.
