Separation of mixtures of fatty acids into individual components using a nanoporous membrane
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 [...]
New biodegradable polymers based on previously unknown functional groups for drug and gene delivery
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 [...]
A Novel Conducting Polymer for Biosensor Applications
Soylemez S., Ekiz Kanik F., Ileri M., Ozdemir Hacıoglu S., Toppare L., Middle East Technical University, TR
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 [...]
Highly Crystalline Poly(lactic acid) (PLA) Alloys Containing Stereocomplexes
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) [...]
Timolol Maleate loaded Chitosan Mucoadhesive Nanoparticles for Ocular Drug Delivery system
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 [...]
Epoxy Toughening with Nano-Sized Amphiphilic Block Copolymer Micelles
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 [...]
Novel In Situ Nano Fibrous Reinforced All Polymer Polypropylene-Nylon Composite
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 [...]
Electrospun Nanofibers of Conductive Polymer Composites
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 [...]
The Coupled Electro-Mechanical Behaviour of Nanocomposites
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 [...]
Microcharacterization of Creep Behavior of Carbon Nanofiber Reinforced HDPE Nanocomposites using a Depth Sensing Method
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 [...]
