Comparative assessment of volume‐of‐fluid (VOF) multiphase solvers for viscoplastic flow over grooved patterned surfaces

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

3D printing of fluorine‐free omniphobic surfaces

Droplet, EarlyView.
Our work demonstrates that the simple and inexpensive digital light processing three‐dimensional printing can be used to fabricate micropillar arrays with doubly reentrant and triply reentrant features. The printed fluorine‐free surfaces display omniphobicity and resist the wetting of liquids with a wide range of surface tensions.

Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Interfacial and Ligand Dual Engineering Toward Energy‐Saving Hydrogen Production Coupled with Sulfion Degradation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Using a coordinated regulation strategy of interface and ligand, we developed a nickel cobalt sulfide/carboxylate ligand‐modified nickel cobalt hydroxide composite (NiCo‐S/NiCo‐OH‐CL) with abundant heterointerfaces. Owing to the porous network, sulfur‐repellent hydrophilic surface, and dual electronic structure regulation, the coupled electrolysis ...

Thermochromic Radiative Cooling Coatings with Robust Superhydrophobicity for Energy‐Efficient Buildings

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable, color‐adaptive radiative cooling coating is developed to enable dynamic spectral regulation via a reversible thermochromic transition at ~45 °C and a high solar reflectance of 91.7%. The coating achieves 4.44 °C outdoor sub‐ambient cooling while providing robust superhydrophobicity and environmental durability through its micro/nano ...

Novel PTFE/PI Nanofibrous Composite Membranes Enabling High‐Flux Desalination and Durable Anti‐Scaling in Membrane Distillation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration comparing the MD performance of pure PTFE NFMs and PTFE/PI NFMs. Polytetrafluoroethylene (PTFE) membranes are widely recognized for their low surface energy and strong resistance to salt accumulation in membrane distillation (MD) processes.
