Objective Polyethylenimine (PEI), a readily available synthetic polycation which has high transfection efficiency owing to its buffering capacity was introduced for transfection a few years ago. But it has been reported that PEI is cytotoxic in many cell lines. In this study, in order to enhance the transfection efficiency of 10 kDa PEI and reduce its toxicity, hydrophobic residues were grafte...

The development of a performant aminated catalyst for aldol condensations requires the combined tuning active site, support and solvent system. For this purpose, pyrrolidine group was immobilized on swellable polymer resin. Favorable interactions between water (in its role as solvent) resulted in turnover frequency (TOF) amounting to 3.0 ± 1.5 × 10−3 s−1, despite potential inhibition sites by f...

In  this  study,  amino  functional  groups  were  chemically  bonded  to  the  surface  of  newly synthesized  KIT-6  mesoporous  magnetite  nanoparticles  (MMNPs)  by  post-toluene  reflux synthesis method.  This method  treats  calcined mesoporous  nanoparticles with  the  functional organosilanes.  Physical  and  chemical  structures  of  the  synthesized  mesoporous  magnetite nanoparticle...

This  article  provides  an  overview  on  preparation,  design,  crystal structure  and  properties  of  some  metal-organic  frameworks  of carboxylate coordination polymers mixed with pyridine-functionality linkers  prepared  in  our  laboratory.  The  article  covers  coordination polymers  in  two-  and  three-dimensional  supramolecular architectures. The reported coordination polyme...

the aim of this study was to develop an extended-release tablet formulation using a new in situ cross-linking method. the effects of polyvalent cations on theophylline release from tablets made with the polyanionic polymers sodium alginate and sodium carboxymethylcellulose, were investigated. different miliequivalents of the di and tri-valent cation, ca2+ and al3+, were added to tablet formulat...
