Amphiphilic Self-assembled Nanoparticles Composed of Chitosan and Ursolic Acid for Protein Delivery on the Skin

Lee S.B., Cho K., Shim J.K., Korea Institute of Industrial Technology, KR

Several promising studies have been reported for the protein delivery such as cytokines using nano-sized particles, which have detrimental effect on the loading the protein without localization and releasing it without deactivation. To design the [...]

Physico-chemical Structure of Multilayer Polyion Complexes Comprising PolyHyrdoxylAmine & Genomie DNA

Harper G., WetaScience, UK

Alternating multilayers of DNA and polyhydroxylamine [PT] were produced on cationic microbeads [C]. DNA elution on two enclosed layers and a surface layer of DNA, provided 10µg DNA/mg bead/ per layer and yield 54µg/mg bead. [...]

Dyeing and Fastness Properties of Acid Dyeable Polypropylene Nanocomposite

Dar Y.S., Fan Q., Ugbolue S.C., Wilson A.R., Yang Y., University of Massachusetts Dartmouth, US

We reported that the dyeability of PP can be improved by mixing nanoclay with the PP matrix. In this paper, we further investigated the PP nanocomposites acid dyeability using three distinct chemical structures, namely, anthraquinone, [...]

Microstructure and Stability of Polymer Nanocomposite

Yin J., Wang X., Fan Y., Lin J., Lei Q., Harbin University of Science and Technology, CN

In this paper, the inorganic nanoparticles (SiO2, Al2O3) hybrid Polyimide (PI) films are prepared by Sol-Gel. The films are yellowish and transparent and the thicknesses are about 2050 m. The microstructure and nanoparticle distribution in [...]

Thermoplastic polyurethane nanocomposites: effect of organoclay structure and hard segment concentration on morphology and properties

Chavarria F., Paul D.R., The University of Texas at Austin and Texas Materials Institute, US

Thermoplastic polyurethane (TPU) nanocomposites were prepared by melt processing using a twin screw extruder. The effects of organoclay structure and hard segment concentration of the TPU matrix on mechanical properties and morphology of the nanocomposites [...]

Novel Biphasic Hydrogels for Controlled Drug Delivery

Parvathy V., University of Queensland, AU

The current methods of drug delivery exhibit specific problems in designing a carrier for long-term release. Our aim is to fabricate biphasic hydrogels of predetermined molecular weights as carriers for long-term drug delivery. The rate [...]

Nanoscopic Tunning via Hydrophilic and Hydrophobic Macro-RAFT

Parvathy V., Univeristy of Queensland, AU

The motivation of this paper is to show the dependence of the morphology on the composition of the copolymers and to explore and understand the influence of morphological features in the nanoscale structure to tailor [...]

Novel Nano-metal Polymeric Composites Fabricated via In-Situ Self Assembly

Vargo T.G., Koloski T.S., MacRae D.M., Lucey D.W., Zhang D., Brupbacher J.B., Integument Technologies, Inc., US

Current research in the field of nanotechnology and the fabrication of polymeric composites is often complicated by the inability to obtain well dispersed nano-particles within polymeric matrices. Current methods require that nanoparticles be protected by [...]

Molecular orientation in electrospun poly(butylene terephthalate) nanofibers

Catalani L.H., Collins G., Jaffe M., University of Sao Paulo, BR

In this work, poly(butylene terephthalate) (PBT) electrospun fibers were produced by conventional electrospinning technique. All typical parameters dependences were studied. Typical behavior was observed for all parameters. In addition, we have analyzed molecular features of [...]
