25 Electrospinning of polymer solutions or melts driven by a high26 voltage electric charge is a highly versatile technique that can be used 27 to generate continuous 1D polymeric fibers with diameters rang28 ing from several micrometers to tens of nanometers. Electrospun 29 nanofibrous materials possess a variety of interesting characteristics 30 such as small dimension, large specific surface...
In this work, the copolymer-based synthesized Cysteine-loaded nanocarriers prepared by a routine protocol, coprecipitation method. It is the first report to investigate the neuroprotective potential and biocompatibility of Cysteine derivatives loaded into poly(ethylene glycol)-block-poly(ε−caprolactone) methyl ether (PEG-b-PCL). The average size of the polymeric/empty NCs was 89 nm and for poly...
in this work, modification of carbon paste electrode surface with poly (2, 5-dimethyl aniline) (p-2,5-dma) by using electrochemical polymerization was described. then, transition metal ions of ni(ii) were incorporated into the polymer film by two ways. at first way, the polymeric modified electrode was immersed in 0.2 m niso4 solutions and the second way was carried out by electrodeposition of ...
Global Classical Solutions to a Compressible Model for Micro-Macro Polymeric Fluids Near Equilibrium
the nanostructured anatase tio2 with high thermal stability was prepared by polymeric sol-gel method without any additives. the particle size distribution of polymeric titania sol was determined by dynamic light scattering (dls). then properties of obtained titania were investigated by tg-dta, xrd, fesem and tem. also, the decolorization capability of resultant anatase was evaluated using methy...
A novel, non-covalent polymeric nanosheet has been produced through small molecule self-assembly; the structure has been characterized by solution NMR, solid-state NMR, powder XRD and AFM.
The increased surface area-to-volume ratio of nanoparticles, quantum size effects and the ability to tune surface properties through molecular modification make nanostructures ideal for environmental remediation. The present piece of work reports the preparation and characterization of nano cellulosic fibers (NCFs) with further polymeric reinforcement using vinyl sulphonic acid for the remediat...

Polymeric materials derived from poly(maleic anhydride-alt-octadecene)-here referred as PAM-18-have shown interesting properties that make them potential pharmaceutical excipients. In this work, eight polymers derived from PAM-18 were obtained using NaOH and KOH at 1:1; 1:0.75, 1:0.5, and 1:0.25 molar ratios. The resulting products were labeled as PAM-18Na and PAM-18K, respectively. Each polyme...
Nowadays, synthesis and application of Metal Nano-Clusters (MNC) attract great attention of scientists and technologists due to their unique electrical, magnetic and optical properties that differ from those of the bulk material. Nevertheless metallic nanoparticles are sometimes unstable and their stabilization is a crucial point to be solved in order to design new sensing devices which contain...
