Objective(s): To improve water stability of electrospun chitosan/ Polyethylene oxide (PEO) nanofibers, genipin, a biocompatible and nontoxic agent, was used to crosslink chitosan based nanofibers.  Materials and Methods: Different amounts of genipin were added to the chitosan/PEO solutions, chitosan/PEO weight ratio 90/10 in 80 % acetic acid, and the solutions were then electrospun to form nano...

Fish gelatin and chitosan were used to develop composite biodegradable films using two strategies: (i) the mixture of both polymers to obtain homogeneous polymer matrixes and (ii) the formation of two layers. The films produced were characterized in terms of water absorption, solubility, water vapour permeability and mechanical properties. Both strategies revealed to produce films with a high s...

to enhance solubility and the performance of a plant gum (from south peach tree of china, sp gum) as a drilling fluid additive, we explored the potential of modified sp (msp) gum by modifying it with epichlorohydrin. the modification conditions, such as the mass ratio of  the crosslinking agent, ph and temperature, were optimized and the results show that 56.40 g/100g mass ratio of the crosslin...

Gelatin fibers have been prepared by dry spinning based on the sol-gel transition phenomena of aqueous gelatin solutions. This method is simple and environmentally friendly because only water is used for the spinning, thereby avoiding the use of any toxic organic solvents. A sol-state aqueous solution of gelatin at 50 ̋C was extruded into air through a thin nozzle at room temperature followed b...

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...

Two novel cyclic quaternary amine crosslinking probes are synthesized for structural mass spectrometry of protein complexes in solution and for analysis of protein interactions in organellar and whole cell extracts. Each exhibits high aqueous solubility, excellent protein crosslinking efficiencies, low collision induced dissociation (CID) energy fragmentation efficiencies, high stoichiometries ...

The concept of crosslinking involves a complicated process of formation of chemical bonds between larger molecules that can change the structure of the material, make it stronger and more resistant to decay. Physical crosslinking with ultraviolet light is used in various fields of industry and medicine for increasing the strength of the material. Chemical crosslinking methods are used in stomat...
