We report a strategy for the fabrication of tailored electroactive nanorod substrates for biospecific studies of cell adhesion and stem cell differentiation; to control the interfacial properties of the nanorods we formed self-assembled monolayers of an electroactive hydroquinone group that is able to chemoselectively immobilize oxyamine tethered ligands.

Claisen rearrangement reaction was employed for the first time to obtain a novel PPTA bearing reactive allyl and hydroxyl groups which may act as a sizing agent of Kevlar fibers to improve the interface structure and interfacial adhesion of rubber or epoxy based composites.

In this work, molecular dynamics (MD) simulations were employed to investigate the effects of duty cycle changes and utilization of tantalum nitride interlayer on the surface roughness and adhesion of Ta coating deposited by pulsed-DC plasma assisted chemical vapor deposition. To examine the simulation results, some selected deposition conditions were experimentally implemented and characterize...

This review is concerned primarily with the correlation between the interfacial interactions and the constitutive properties of low-energy organic surfaces. It starts with a discussion on the estimation of the surface free energy of organic solids from contact angles, followed by a review of the surface energetics and adhesion. The experimental measurements of surface free energy, in most cases...

The chemistry of mussel adhesion has commanded the focus of much recent research activity on wet adhesion. By comparison, the equally critical adhesive processing by marine organisms has been little examined. Using a mussel-inspired coacervate formed by mixing a recombinant mussel adhesive protein (fp-151-RGD) with hyaluronic acid (HA), we have examined the nanostructure, viscosity, friction, a...

The actions of cell adhesion molecules, in particular, cadherins during embryonic development and morphogenesis more generally, regulate many aspects of cellular interactions, regulation and signaling. Often, a gradient of cadherin expression levels drives collective and relative cell motions generating macroscopic cell sorting. Computer simulations of cell sorting have focused on the interacti...
