Hydrophobic molecules are by definition difficult to hydrate. Previous studies in the area of hydrophobic hydration have therefore often relied on using amphiphilic where hydrophilic part a...

We have shown that the lattice fluid hydrogen bond ~LFHB! model can successfully quantify the first-order volume transition in hydrogels. The model predicts that a critical balance of hydrophilic and hydrophobic interactions is required for a gel to exhibit a discontinuous volume transition. In this work we will report the swelling behavior of a new thermoreversible copolymer hydrogel, which ha...

A conductive engineered cardiac patch (ECP) can reconstruct the biomimetic regenerative microenvironment of an infarcted myocardium. Direct ink writing (DIW) and 3D printing produce ECP with precisely controlled microarchitectures. However, developing a printed high conductivity flexibility for gapless attachment to conform epicardial geometry remains challenge. Herein, asymmetrical DIW hydroph...

In this paper we present a monolithic fabrication process for microcapillary sys tems that permits the formation of stable, photo-definable hydrophobic ( ) and hydrophilic ( ) regions on plastic channels. Using this process we have demonstrated a simple injector that uses a hydrophobic patch for cutting and transporting sample drops. Hydrophobic regions are formed by coating the inner walls wit...

Bioinspired functional surfaces are attracting increasing interest in surface engineering, mostly the field of wettability. The Salvinia-effect is a remarkable example superficial air retention and drag force reduction caused by selective chemical coating (super-hydrophobic wax hydrophilic dead cells) peculiar 3D hierarchical morphological structures. replication Salvinia-like patterns at micro...

The growth of Escherichia coli DH5α recombinants producing eicosapentaenoic acid (EPA) (DH5αEPA+) and those not producing EPA (DH5αEPA-) was compared in the presence of hydrophilic or hydrophobic growth inhibitors. The minimal inhibitory concentrations of hydrophilic inhibitors such as reactive oxygen species and antibiotics were higher for DH5αEPA+ than for DH5αEPA-, and vice versa for hydroph...

Block-copolymer amphiphiles have been observed to assemble into vesicles and other morphologies long known for lipids but with remarkably different properties. Coarse-grain molecular dynamics (CG-MD) is used herein to elaborate the structures and properties of diblock copolymer assemblies in water. By varying the hydrophilic/hydrophobic ratio of the copolymer in line with experiment, bilayer, c...
