We recently developed the first method to separate fatty acids derived from vegetable oils using nanoporous membranes based on polydicyclopentadiene. Fatty acids were too small and too similar in size to be separated from one [...]

We developed the synthesis of three new sets of polymers based on bonds between sulfur and nitrogen for applications in drug and gene delivery. These polymers were designed to slowly degrade in water at pH [...]
Cyanoacrylate nanoparticles have been studied in great detail over the past three decades with a view to their use as controlled release drug delivery materials. The mechanism of polymerization is anionic where the initiating species [...]

In this study, 2-(4-fluorophenyl)-4,7-di(thiophene-2-yl)-1H-benzo[d]imidazole, a novel monomer, was synthesized and its polymer was used for the immobilization matrix for cholesterol oxidase (ChOx). A novel cholesterol biosensor was generated. The designed conducting polymer based biosensor showed [...]
Poly(lactic acid) (PLA) is known as a bio-based polymer, which usually has low heat tolerance. Furthermore, the brittleness of PLA limits its applications. It is reported that the melting temperature (Tm) of crystalline stereocomplexes (sc) [...]
The objective of this study involved the design of mucoadhesive nanoparticulate carrier system containing Timolol Maleate for ocular delivery to improve its corneal absorption. Nanoparticles were synthesised by template polymerization method and the process optimization [...]

A model diglycidyl ether of bisphenol A (DGEBA) epoxy resin was modified with a poly(ethylene-alt-propylene)-b-poly(ethylene oxide) (PEP-PEO) block copolymer to improve fracture toughness. Two distinct nanoscaled morphologies were achieved in the cured systems: spherical micelles [...]
Self reinforced polymer composites are significantly different than the conventional fiber reinforced composites since there is no external additive and the polymer itself assumes fibrous morphology during melt /solution processing. In such materials, typically liquid [...]
Conjugated polymer composites with different dielectric properties can be widely used in electronics industry, sensors, batteries, smart windows and to reduce electromagnetic interference. In this study monodispersed polypyrrole composite nanospheres were synthesized by the presence [...]
In the past two decades, practical realisation of composites began to shift from microscale-reinforced composites to nano-reinforced composites using carbon nanotubes (CNTs). There are a number of advantages that result from dispersing CNTs into polymeric [...]

Depth-sensing indentation at micro- and nano-scale levels is a useful tool for material characterization due to its simplicity. There are many well-established methods for determining local mechanical properties including elastic modulus, hardness, and fracture toughness [...]
