Jude K. Coompson, B.S. Marquette University, 2014 Benzene is a constituent component of crude oil that has been classified as a carcinogen by the EPA with a maximum contamination level (MCL) of 5ppb in drinking water. However, of the aromatic compounds, benzene has one of the lowest polymer-water partition coefficients using commercially available polymers as sensor coatings, resulting in poor ...

In recent years, the demand for a natural plant-based polymer with potential functions from plant sources has increased considerably. The main objective of the current study was to study the effect of chemical extraction conditions on the rheological and functional properties of the heteropolysaccharide/protein biopolymer from durian (Durio zibethinus) seed. The efficiency of different extracti...

A non-vacuum processing method for preparing polymer-based ZrO2/TiO2 multilayer structure antireflection coating (ARC) films for crystalline silicon solar cells by spin coating is introduced. Initially, ZrO2, TiO2 and surface deactivated-TiO2 (SD-TiO2) based films were examined separately and the effect of photocatalytic properties of TiO2 film on the reflectivity on silicon surface was investi...

In Germany, four different drug eluting stents (DES) systems are currently commercially available. Whereas sirolimus has been clinically tested in only a single type of stent with a single type of coating in only a single dose, paclitaxel has been tested on various stent designs, in various dose densities, and in various release formulations with or without a polymer carrier. Therefore, the que...

A novel sulfamethazine molecularly imprinted polymer (MIP)-coated stir bar for sorptive extraction of eight sulfa drugs from biological samples was prepared. The MIP-coating was about 20 μm thickness with the relative standard deviation (RSD) of 6.7% (n=10). It was characterized by scanning electron microscope, infrared spectrum, thermogravimetric analysis, and solvent-resistant investigation, ...

Highly porous 45S5 Bioglass(®)-based scaffolds coated with two polymer layers were fabricated to serve as a multifunctional device with controlled drug release capability for bone regeneration applications. An interior poly(d,l-lactide)/poly(ethylene glycol)-(polypropylene glycol)-poly(ethylene glycol) triblock copolymer (Pluronic P123) coating improved the mechanical stability of Bioglass-base...

Objective(s):  It is proposed that particulate antigens could better interact with the antigen presenting cells (APCs). A fast, simple and scalable process for preparation of polymeric nanoparticles (NPs) is coating of charged antigenic particles, like viruses, with oppositely charged polymers. A second coating with a charged polymer could increase the stability and modify the immunomodulatory ...

Polym. Adv g liquid processed polymer deposition method for the film preparation of functional polymers in photo-electronic devices. In this report, the results on the IJP of a fluorenebased electroluminescent polymer, poly(9,9-dihexylfluorene-alt-2,5-dioctyloxybenzene) (PF6OC8), from a piezoelectric droplet generator are presented. The polymer film thickness has been found to show an approxima...

In this work, the process of spin dewetting of a polymer solution on a topographically patterned PDMS mold was used for fabrication of microand nanaoscale polymer structures. Spin coating was used to provide a fast and reproducible coating. This simple technique was capable of producing a wide range of polymer feature geometries from a single microfabricated mold. This experimental study looks ...

The conformation of a three-dimensional polymeric coating (copoly(DMA-NAS-MAPS)) and immobilization and hybridization of DNA strands on the polymer coated surface are investigated. A conformational change, specifically the swelling of the surface adsorbed polymer upon hydration, is quantified in conjunction with the application of this polymer coating for DNA microarray applications. Fluorescen...
