However, a cross-linking by high concentration glutaraldehyde provides the braids with a swelling phenomenon, which in turn causes a dense internal feature of the braids, and namely a lower porosity. This study successfully prepares braided PVA bone scaffolds with water stability, through a glutaraldeh...
coatings, and patterns with Cell-ImCNCl as the raw material and by employing various solution processing methods. A small amount of glutaraldehyde was added to the Cell-ImCNCl solution to form a stable double crosslinking structure. As a result, the resulting phosphorescent patterns exhibited excell...
Carbon dioxide (CO2) emission to the atmosphere is the prime cause of certain environmental issues like global warming and climate change, in the present d
The crosslinking agent may be selected from the group consisting of cyanuric chloride, trimesoyl chloride, terephthaloyl chloride, epichlorohydrin, dibromobenzene, glutaraldehyde, phenylene diisocyanates, tolylene diisocyanates, divinyl sulfone, 1,1′-carbonyldiimidazole and alkoxysilanes. In the material ...
ii. an amount of glutaraldehyde from about 0.03 to about 10 percent of the weight of said gel-forming composition, and iii. an amount of a crosslinking catalyzing substance, which in combination with said aqueous solution and glutaraldyhyde, is operable for effecting gelation, at the temperature...
A chemical cross-linking reaction was performed using glutaraldehyde with a molar proportion (GA/monomer alcohol) of 0.04. Results showed that the cross-linking control was the key step to obtain porous membrane morphology. Consequently, the temperature and the catalyst volatility of the cross-...
The thermal study of the immobilized HRP enzyme provide for the first time additional information regarding the interaction of the HRP enzyme molecules with the PVA chains of the nanofiber matrix, as well as the effect of the cross‐linking time in the glass transition temperature and the heat ...
solution of PVA/PVA-copolymer, a crosslinking agent [(c') or (c")] containing at least two functional groups and optionally ionisable groups, and optionally a leachable water-soluble additive on said porous support, optionally drying the film, crosslinking it, and then reacting it with ...
In still another embodiment, the process further comprises preventing the introduction into the subterranean formation of an effective amount of a crosslinking catalyzing substance under conditions which are operable for causing substantial mixing of the crosslinking catalyzing substance with the gel-forming...
The highly swellable PVA matrix loaded with diltiazem hydrochloride was obtained by means of a simplified procedure of the polymer crosslinking reaction using glutaraldehyde in solution with ammonium persulfate. The undried swollen matrix was coated with a calcium alginate membrane employing an ionotropic...
