The crystalline cyclic oligosaccharide γ-cyclodextrin (γCD) is a natural, non-toxic and biodegradable precursor that can be used to prepare innovative polymers. We cross-linked γCD with variable quantities of polyethylene glycol diglycidyl ether (PEGDGE) in aqueous NaOH form 3D structures tunable physicochemical properties. Mixtures 5 : 1 PEGDGE:γCD molar ratio produced material was soluble wat...

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...

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.

due to unique applications of palladium nanoparticles, synthesis of these nanoparticles by a simple andlow cost method is very important. in this work, pd nanoparticles were synthesized with narrow sizedistribution by loading metal salt (pd(oac)2 ) into the polymeric matrix (peg) as reducing agent andstabilizer. also, the effect of metal salt concentration and peg molecular weight on the conver...

Protein delivery across polarized epithelia is controlled by receptor-mediated transcytosis. Many studies have examined basolateral-to-apical trafficking of polymeric IgA (pIgA) by the polymeric immunoglobulin receptor (pIgR). Less is known about apical-to-basolateral transcytosis, the direction the neonatal Fc receptor (FcRn) transports maternal IgGs across intestinal epithelia. To compare api...

Extensive studies on the correlation between synthesis variables and final properties of resorcinol-formaldehyde carbon gels have been performed. This knowledge allows us to obtain with analogous mean pore sizes porosity from different combinations variables. However, although materials exhibit these similar characteristics, their behaviors may be very in certain applications. Since distributio...

The photocatalytic activity of polymeric carbon nitride (CN) is strongly tied to its surface area, morphology, optical, and electronic properties. Herein, a straightforward approach adjusting the properties morphology CN materials by fine tuning their content while preserving high area proposed. To do so, supramolecular assemblies based on monomers together with an additional carbon-rich monome...
