in present research work, homogeneous anion exchange membranes based on polysulfone (qapsfs) were prepared via chloromethylation, amination and alkalization. in amination step, trimethylamine and n,n,n',n'-tetramethyl-1,6-hexanediamine were used as amination and crosslinking agents, respectively. the chloromethylated polysulfone was characterized by 1hnmr spectroscopy and chloromethylation degr...

AbstractIn the last step of desolvation method for preparation of albumin nanoparticles, glutaraldehyde (GA) is added to stabilize the newly formed nanoparticles. Due to undesirable effects of GA, the objective of this study was to evaluate alternative methods of crosslinking including ultraviolet (UV) irradiation, adding of glucose and combination of both methods. The nanoparticles were prepar...

Chemical crosslinking in combination with Fourier transform ion cyclotron resonance mass spectrometry (FTICR MS) has significant potential for studying protein structures and protein-protein interactions. Previously, cisplatin has been shown to be a crosslinker and crosslinks multiple methionine (Met) residues in apo-calmodulin (apo-CaM). However, the inter-residue distances obtained from nucle...

Crosslinking is an established treatment to alter the physicochemical and functional properties of polymers through creation bonds between polymer chains. Polymers can be crosslinked via radiation in presence photo-initiator. The aim present study was formulate 3D-printed theophylline (THEO) tablets using polyethylene oxide (PEO) as a carrier polymer, influence crosslinking on drug release beha...

Integrally-skinned asymmetric Polyetherimide/Poly (vinyl alcohol) (PEI/PVA) hollow fber membranes for pervaporation dehydration were fabricated by non-solvent induced phase inversion. PVA inside the PEI matrix could be crosslinked to provide membrane performance stability during long term operation. The effects of different PEI/PVA blend ratio, external coagulant type and...
