Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.Porous proton‐exchange membrane electrolysis enables the synthesis of electrolyte‐free H2O2 at low cell resistance. Optimized Nafion loading to the porous membrane, acid‐treated Co─N─C single‐atom catalysts, and hydrophilic SiO2 achieved H2O2 Faradaic efficiency (FE) of 75% at 100 mA cm−2 with ∼2.3 V.

In‐Mold Wettability Patterning of Microfluidic Devices Without Back‐End Surface Modification
Chemistry–Methods, Volume 6, Issue 6, June 2026.This study demonstrates in‐mold wettability patterning of microfluidic devices, eliminating the need for post‐fabrication surface modification to define hydrophilic and hydrophobic regions. The new approach enables efficient droplet seeding in hydrophilic‐in‐hydrophobic well arrays and selective wettability of microchannels in fluidic devices.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
Heat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Adaptive Liquid Lens Actuated by Droplet Movement
Micromachines, 2014 In this paper we report an adaptive liquid lens actuated by droplet movement. Four rectangular PMMA (Polymethyl Methacrylate) substrates are stacked to form the device structure. Two ITO (Indium Tin Oxide) sheets stick on the bottom substrate.

Statistical Mechanics of Electrowetting
EntropyWe derive the ab initio equilibrium statistical mechanics of the gas–liquid–solid contact angle on planar periodic, monodisperse, textured surfaces subject to electrowetting. To that end, we extend an earlier theory that predicts the advance or recession
