Chemical Society Reviews, Journal Year: 2022, Volume and Issue: 51(11), P. 4537 - 4582

Published: Jan. 1, 2022

Water channels are one of the key pillars driving development next-generation desalination and water treatment membranes. Over past two decades, rise nanotechnology has brought together an abundance multifunctional nanochannels that poised to reinvent separation membranes with performances exceeding those state-of-the-art polymeric within water-energy nexus. Today, these can be broadly categorized into biological, biomimetic synthetic, owing their different natures, physicochemical properties methods for membrane nanoarchitectonics. Furthermore, against backdrop mechanisms, types nanochannel exhibit unique merits limitations, which determine usability suitability designs. Herein, this review outlines progress a comprehensive amount nanochannels, include aquaporins, pillar[5]arenes, I-quartets, nanotubes porins, graphene-based materials, metal- covalent-organic frameworks, porous organic cages, MoS2, MXenes, offering comparative glimpse where potential lies.

Dual-bionic superwetting gears with liquid directional steering for oil-water separation

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: July 12, 2023

Developing an effective and sustainable method for separating purifying oily wastewater is a significant challenge. Conventional separation membrane sponge systems are limited in their long-term usage due to weak antifouling abilities poor processing capacity with multiple oils. In this study, we present dual-bionic superwetting gears overflow system liquid steering abilities, which enables the of oil-in-water emulsions into pure phases. This achieved through synergistic effect surface superwettability complementary topological structures. By applying energy matching principle, water oil mixture rapidly continuously spread on preferential gear surfaces, forming distinct films that repel each other. The structures facilitate rapid transfer films, resulting high flux assistance rotational motion. Importantly, model mitigates decrease caused by fouling maintains consistently efficiency oils varying densities tensions.
