Firstly, this work shows the crosslinking of Polyurethane/Single Wall Carbon Nanotube/ Polymethyl Methacrylate (PU/SWCNT/PMMA) nanocomposite at 298.15K using PM3 semi-empirical method (Parameterized Model number 3), where reaction was spontaneous and endothermic. The log P indicated a hydrophobic character. Subsequently, Monte Carlo simulation carried out 303.15, 313.15 323.15K, Gibbs free ener...

In this work, nanocomposite (NC) hydrogels based on polyacrylamide/chromium triacetate were prepared at different reaction mixture (gelant) volumes and their crosslinking process and viscoelastic behaviors were studied. The X-ray diffraction (XRD) patterns taken from the NC hydrogels containing laponite nanoparticles did not show any distinct characteristic basal reflection for all of the NC hy...

production and characterization of soft cross-linked gelatin sponge by using glutaraldehyde for blood hemostasis application, is the goal of this study. biodegradable hydrogels were prepared through crosslinking of gelatin with glutaraldehyde followed by freeze drying. the effects of gelatin concentration, amount of crosslink agent and freeze drying temperature on mechanical properties and elas...

We present a method and several applications for the synthesis of hydrogel-crosslinked microneedle arrays utilizing microwave-assisted drying, ensuring significant reduction in reaction preparation time while maintaining quality. demonstrate feasibility drying hydrogels using microwaves thus extend to crosslinked fabrication. Crosslinking was performed 1,4-butanediol diglycidyl ether (BDDE) as ...

A totally green process based on reactive extrusion was used for the production of cassava starch hydrogels through reaction with two organic crosslinking agents, citric (CA) and tartaric (TA) acids. CA TA were at different concentrations (0, 2.5, 5.0, 10.0, 15.0, 20.0%). Degree substitution (DS) ranged from 0.023 to 0.365. Fourier transform infrared spectroscopy results showed a new band appea...

Decellularized xenogeneic whole-liver matrices are plausible biomedical materials for the bioengineering of liver transplantation. A common method to reduce the inflammatory potential of xenogeneic matrices is crosslinking. Nevertheless, a comprehensive analysis of the immunogenic features of cross-linked decellularized tissue is still lacking. We aimed to reduce the immunogenicity of decellula...

4-Thiothymidine and 6-thiodeoxyguanosine were incorporated into synthetic dodecamers containing the recognition site d(GATATC) of the enzymes Eco RV endonuclease and Eco RV methyltransferase. Upon irradiation with long wavelength UV light (340-360 nm), these oligodeoxynucleotides were photochemically crosslinked to both enzymes. The yields were up to 35% with the methyltransferase, but lower (u...
