Nanotechnology remains the field to explore in the quest to enhance therapeutic efficacies of existing drugs. Fabrication of a methacrylate copolymer-lipid nanoparticulate (MCN) system was explored in this study for oral drug delivery of levodopa. The nanoparticles were fabricated employing multicrosslinking technology and characterized for particle size, zeta potential, morphology, structural ...

Calix[4]pyrrole-based porous organic polymers (P1–P3) for removing micropollutants from water were prepared. A bowl-shaped α,α,α,α-tetraalkynyl calix[4]pyrrole and diketopyrrolopyrrole monomer crosslinked via Sonogashira coupling to produce a 3D network polymer, P1. P1 proved too hydrophobic use as an adsorbent was converted the corresponding neutral polymer P2 (containing carboxylic acid group...

a  new  type  of  cation-exchange  nanocomposite  membranes  was prepared  by  in-situ  formation  of  zno  nanoparticles  in  a  blend containing  sulfonated  poly  (2,6-dimethyl-1,4-phenylene  oxide)  and sulfonated polyvinylchloride  via  a  simple  one-step  chemical method.  as-synthesized  nanocomposite  membranes were characterized  using  fourier  transform  infrared  spectroscopy, scan...

attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (tpe) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. in order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic modul...
