A new approach has been developed to fabricate tough hybrid hydrogels by employing dual enzyme-mediated redox initiation to achieve post-self-assembly cross-linking polymerization. The resulting hydrogel combines the merits of supramolecular hydrogels with polymeric hydrogels to achieve higher mechanical strength and porous networks. Designed 3D constructs were fabricated via in situ 3D printin...
Core-shell 12-tungstophosphoric acid/TiO2 (HPW/TiO2) nanoparticles at 10 and 20% of HPW have been synthesized by simple in-situ sol- gel method. Characterization of the samples was carried out by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared (FTIR). The X-ray diffraction patterns of as prepared solid samples, indicated characterist...
Sustained drug delivery has become the standard in modern Pharmaceutical design and an intensive research has been undertaken in achieving much better drug product effectiveness, reliability and safety. This interest has been sparked by the advantages shown by in-situ forming polymeric delivery systems such as ease of administration and reduced frequency of administration, improved patient comp...
styrene nanocomposites were synthesized by in-situ atom transfer radical polymerization at 110oc. the variations of monomer conversion and the linearity of semilogarithmic kinetic plot, some signs of living polymerizationand constant radical concentration in the reaction medium, were revealed by gas chromatography technique (gc). according to the gel permeation chromatography (gpc) results, the...
