Objective(S): Implant-related infections are disastrous complications in the clinic. One recent strategy to reduce the rate of infection is using the bioactive coating with an antibiotic. The purpose of these bioactive surfaces is to prevent bacterial adhesion to the implant and, consequently, the development of biofilm. In this study, vancomycin-loaded polymeric coating on imp...

Blockage of pipelines by formation and accumulation of clathrate hydrates of natural gases (also called gas hydrates) can compromise project safety and economics in oil and gas operations, particularly at high pressures and low temperatures such as those found in subsea or arctic environments. Cyclopentane (CyC5) hydrate has attracted interest as a model system for studying natural gas hydrates...

Surface modification of neural prosthetic electrodes with polymeric materials, in particular, conducting polymers and hydrogels, has the potential to circumvent many problems associated with currently used electrode platforms. These problems include the disparity in mechanical properties between implanted electrodes and host neural tissue and the lack of biofunctionality at the electrode surfac...

Physically adsorbed (dynamic) polymeric wall coatings for microchannel electrophoresis have distinct advantages over covalently linked coatings. In order to determine the critical factors that control the formation of dynamic wall coatings, we have created a set of model polymers and copolymers based on N,N-dimethylacrylamide (DMA) and N,N-diethylacrylamide (DEA), and studied their adsorption b...

Prevention of microbially induced corrosion (MIC) is of great significance in many environmental applications. Here, we report the use of an ultra-thin, graphene skin (Gr) as a superior anti-MIC coating over two commercial polymeric coatings, Parylene-C (PA) and Polyurethane (PU). We find that Nickel (Ni) dissolution in a corrosion cell with Gr-coated Ni is an order of magnitude lower than that...

Biocidal coatings that are based on quaternized ammonium copolymers were developed after blending and crosslinking and studied as a function of the ratio of reactive groups and the type of biocidal groups, after curing at room temperature or 120 ◦C. For this purpose, two series of copolymers with complementary reactive groups, poly(4-vinylbenzyl chloride-co-acrylic acid), P(VBC-co-AAx), and pol...
