11. Degradation of acrylonitrile butadiene rubber and fluoroelastomers in rapeseed biodiesel and hydrogenated vegetable oil
Abstract : Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. READ MORE

12. Influence of processing and processing additives on the degradation of aliphatic polyesters
Abstract : Poly(3-hydroxybutyrate-co-3-hydroxyvalerate), P(3HB-co-3HV),poly(ε-caprolactone), PCL, and poly(lactic acid), PLA,have been subjected to film-blowing, melt-extrusion andmelt-pressing. The influence of processing conditions andprocessing additives (i.e. plasticizer, antiblocking and slipagents) on properties and degradation have been studied. READ MORE

13. Design of new biodegradable polymer matrices for controlled drug delivery
Abstract : Conventional drug administration technologies display poorcontrollability, and lead to high plasma concentrations andshort duration times, which frequently lead to adverse effects.Controlled release technology aims at predictable andreproducible delivery of an active substance over an extendedperiod of time, yielding optimal response and prolongedefficiency, and thus offering considerable improvement of manytreatments.

14. Bioprocessing, Structure and Material Properties of Arabinoxylans
Abstract : This work has focused on using agriculture residues as raw material for new polymeric materials. Arabinoxylans have been isolated from barley husks and endosperm fiber using alkali extraction, and the chemical composition and detailed structure have been determined. READ MORE

15. Poly(Alkylthiophene) Blends Processing, Morphology and Conductivity
Abstract : Intrinsically conducting polymers may be an attractive alternative instead to polymers with conducting fillers. The aim of the present work was to study the potential of the processable conducting polymer poly(3-alkylthiophene) as well as possible problems related to its processing. READ MORE
