Water Drops Sliding Over Arrays of Janus Micropillars With Hydrophilic Tops: A New Mechanism of Drop Charging

Small, EarlyView.
A water drop slides over a distance of a few centimeters across arrays whose top surfaces exhibit a contact angle below 10°. The arrays are fabricated with hydrophilic tops and hydrophobic sidewalls and substrate, forming Janus structures. As the drop moves, it generates a spontaneous electric charge and leaves behind tiny satellite droplets that ...

Amphiphilic Polyphosphazene for Fluorocarbon Emulsion Stabilization [PDF]

High internal phase emulsions (HIPEs) have been of great interest for fabricating fluorinated porous polymers having controlled pore structures and excellent physicochemical properties. However, it remains a challenge to prepare stable fluorocarbon HIPEs,

Radiation‐Based 3D Dual‐Mode Thermal Management Devices: Advances in Active/Passive Switching for Energy‐Saving Applications

Small, EarlyView.
Heating and cooling energy demand account for nearly half of the global energy consumption. SH and RC offer sustainable, zero‐energy strategies, but single‐mode devices lack adaptability. 3D dual‐mode devices, exploiting axial, flipping, and bending deformations, provide reversible switching with dynamic or passive control, representing a promising ...

Influence of Diffusivity and Sorption on Helium and Hydrogen Separations in Hydrocarbon, Silicon, and Fluorocarbon-Based Polymers

, 2016
The permeability–selectivity upper bounds show that perfluoropolymers have uniquely different separation characteristics than hydrocarbon-based polymers. For separating helium from hydrogen, these differences are particularly dramatic.

Impact of Ions and Radicals on Etch Selectivity and Fluorocarbon Polymerization in the Selective Dry Etching of Si0.7Ge0.3

Plasma Processes and Polymers, Volume 23, Issue 6, June 2026.
Ion screening in CF4 plasma reduces CFx+ ion flux while maintaining radical fluxes, suppressing fluorocarbon polymer accumulation. This enables smooth SiGe etching with selectivity up to 30:1 in multilayer stacks. ABSTRACT Selective etching of Si0.7Ge0.3 was investigated in CF4 inductively coupled plasma using an ion‐screening approach to decouple ion ...
