“…For example, a higher DS is effective for cross-linking of CMC due to the fact that intermolecular linkages are result of ether function (Shen et al, 2006;Wach et al, 2003a). Similar results have been reported on aqueous state irradiation of methylcellulose and hydroxypropyl cellulose (Horikawa et al, 2004;Wach et al, 2003b), carboxymethyl starch , gum arabic (Katayama et al, 2006), carboxymethylated chitin and chitosan (Wasikiewicz et al, 2006;Zhao et al, 2003a). The % hydrogel produced together with the proposed application from various investigations are summarised in Table 3.…”

“…Normally the hydrogel content of a given material is estimated by measuring its insoluble part in dried sample after immersion in deionised water for 16 h (Katayama, Nakauma 2006) or 48 h at room temperature (Nagasawa et al, 2004). The sample should be prepared at a dilute concentration (typically ~ 1%) to ensure that hydrogel material is fully dispersed in water.…”

Abstract:The radiolysis of water due to ionizing radiation results in the production of electrons, H  atoms,  OH radicals, H 3 O + ions and molecules (dihydrogen H 2 and hydrogen peroxide H 2 O 2 ). A brief history of the development of the understanding of water radiolysis is presented, with a focus on the H 2 production. This H 2 production is strongly modified at oxide surfaces. Different parameters accounting for this behavior are presented.

Objective: A novel cross-linked keratin hydrogel was prepared by integrating keratin from chicken feather into an aloe-vera, Chitosan and honey based dressing formulation separately.Methods: Keratin fibres extracted from chicken feathers are eco-friendly, non-abrasive, biodegradable, insoluble in organic solvents and having good mechanical properties, hydrophobic behaviour, low density and finally cheap. Keratin based hydrogels were prepared with five types of ingredients and studied for their wound healing properties. The analysis of keratin-based hydrogel was done by Fourier Transform Infra-red Spectroscopy (FTIR) and X-ray diffraction (XRD) analysis.Results: Keratinocytes containing keratin travel from the wound border to initiate the process of healing. The characteristics of keratin-based hydrogel derived from chicken feather made it an effective wound care therapeutic product. X-ray diffraction (XRD) analysis showed the crystallinity index in between 30-50% of the hydrogen. Conclusion:The test for swelling and solubility were carried out on the hydrogen to determine the solid content and water absorbance capacity. Overall, this product is safe to use as an effective wound healing product with appropriate properties.
