The phase-out of long-chain C8-based perfluorochemicals necessitates the textile industry to find the best alternatives to these durable oil- and water-repellent chemistries. Finding out the alternatives has resulted in a textile market where both fluorine-based and fluorine-free durable water repell...
Dispersion of colloidal particles in water or oil is extensively desired for industrial and environmental applications. However, it often strongly depends on indispensable assistance of chemical surfactants or introduction of nanoprotrusions onto the particle surface. Here we demonstrate the omnidispersity o...
Here, we investigate the bubble bursting dynamics at an oil-covered aqueous surface by high-speed imaging, to characterize the previously unknown interplay between bubbles and a structurally complex interface with an insoluble viscous oil layer. We show that a compound multiphase jet is formed, resul...
One of the common EOR (i.e., tertiary oil recovery) methods is chemical flooding. The formation of crude oil-in-water (crude O/W) emulsions is one of the key mechanisms in enhancing the recovery of the trapped oil during chemical flooding (Bryan and Kantzas, 2009; Dong et al., 2009...
Aqueous two-phase system (ATPS) droplets have demonstrated superior compatibility over conventional water-in-oil droplets for various biological assays. However, the ultralow interfacial tension hampers efficient and stable droplet generation, limiting f
The unique structural, dynamical and chemical properties of air/water and oil/water interfaces are thought to play a key role in various biological, geological and environmental processes. For example, non-hydrogen-bonded (‘dangling’) OH groups—which create surface defects in water's hydrogen bo...

Introduction Unconventional resources are classified as the reservoirs with too low permeability such as tight oil or gas, gas shales, and coalbed methane reservoirs or with too high vi...
1. A water- and oil-repellent composition comprising (a) a repellency-imparting, fluorochemical composition comprising at least one fluorine-containing aromatic ester oligomer comprising (1) at least two repeat units from the reaction of at least one dicarboxylic acid and at last one polyol, with...
1. A water- and oil-repellent, antistatic composition comprising (a) at least one nonpolymeric ionic salt consisting of (i) at least one cation selected from the group consisting of monovalent metal cations,divalent metal cations, and organic onium cations and (ii) at least one weakly coordina...
