Abstract Nowadays, coatings need to fulfill a variety of requirements such as having excellent mechanical, chemical, and optical properties at low baking temperatures. On large scale, polyisocyanates, amines or melamines are used crosslinking agents in the industry. In this work, new self-crosslinking agent based on hydroxy functional 6-membered carbonate with high ring tension thus presumably ...
native fish gelatin has some disadvantages such as high hydrophilic, and solubility in cold water. mixing with other biopolymers and crosslinking by sugars may improve functional properties of fish gelatin. so in this research, the effects of ribose were investigated on moisture sorption isotherm, solubility in water, and mechanical properties of cold water fish gelatin (cwfg) films. ribose sug...
14C-labeled SV40 DNA has been transcribed with E. coli RNA polymerase using 3H-labeled ribonucleotide triphosphates as precursors. The resulting transcription complexes were then photochemically crosslinked with the psoralen derivative, 4'-aminomethyl-4,5', 8-trimethylpsoralen (AMT), at 37 degrees C and analyzed in SDS-sucrose gradients. It was found that the photochemical crosslinking procedur...
The antimicrobial activity of a wound dressing is a key factor for preventing and treating wound infection. The current study evaluated the physiochemical properties and antimicrobial activities of semi-IPNs (interpenetrating polymer networks) based on chitosan/polyvinyl alcohol (PVA) films and nanofibers as candidates for wound dressings and investigated the effects of morphologies (nanofibrou...
In this paper, N, N’-m-phenylene dimaleimide (HVA-2) grafted crosslinked polyethylene (XLPE) insulation materials with different HVA-2 contents were prepared. The grafting, crosslinking, and crystalline structure characterized by Fourier-transform infrared spectroscopy (FTIR), Soxhlet extraction, differential scanning calorimetry (DSC), respectively. space charge distribution, direct current (D...
Bioconjugation based on crosslinking primary amines to carboxylic acid groups has found broad applications in protein modification, drug development, and nanomaterial functionalization. However, proteins, which are made up of amino acids, typically give nonselective bioconjugation when using primary amine-based crosslinking. In order to control protein orientation and activity after conjugation...
