“…As can be seen, the T d and Δ w increased, but the residue (%) decreased with the increase of TiO 2 NPs content from 0.5% to 2% in CH films. The result revealed that CH films incorporated with TiO 2 NPs significantly improved the thermal stability of CH films compared to the control film, which can be ascribed to the better thermal stability of TiO 2 when compared with CH and to good interaction between TiO 2 and CH …”

In the present research, titanium dioxide (TiO2) nanoparticles (NPs) were prepared by using sol‐gel technique, and the phase structure and morphology of obtained TiO2 NPs were characterized by using X‐ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The XRD patterns of the TiO2 NPs indicated the formation of anatase phase. A new nanocomposite film has been developed by solvent casting method from collagen hydrolysate (CH) and TiO2 NPs at different concentrations for use in packaging industry. Fourier transform infrared (FTIR) spectra showed the intermolecular reactions between CH and TiO2 NPs in the films. SEM micrographs revealed a clear dispersion of TiO2 NPs on the surface of the films especially at low concentrations. Thermal analyses showed that after incorporation of TiO2 NPs in polymer matrix, heat susceptibility of films were changed and weight loss of films was decreased. The results revealed that incorporation of TiO2 NPs significantly decremented water vapor permeability (WVP), water solubility, and elongation at break (EAB) of the films, whereas tensile strength (TS) significantly incremented. The findings pointed out that TiO2 NPs can be successfully incorporate to the CH films and the reutilization of CH in nanocomposite films will be a promising alternative material in non‐food packaging industry.

Management of burn wounds with diabetes and microbial infection is challenging in tissue engineering. The delayed wound healing further leads to scar formation in severe burn injury. Herein, a silver‐catechin nanocomposite tethered collagen scaffold with angiogenic and antibacterial properties is developed to enable scarless healing in chronic wounds infected with Pseudomonas aeruginosa under diabetic conditions. Histological observations of the granulation tissues collected from an experimental rat model show characteristic structural organizations similar to normal skin, whereas the open wound and pristine collagen scaffold treated animals display elevated dermis with thick epidermal layer and lack of appendages. Epidermal thickness of the hybrid scaffold treated diabetic animals is lowered to 33 ± 2 µm compared to 90 ± 2 µm for pristine collagen scaffold treated groups. Further, the scar elevation index of 1.3 ± 0.1 estimated for the bioengineered scaffold treated diabetic animals is closer to the normal skin. Immunohistochemical analyses provide compelling evidence for the enhanced angiogenesis as well as downregulated transforming growth factor‐ β1 (TGF‐β1) and upregulated TGF‐β3 expressions in the hybrid scaffold treated animal groups. The insights from this study endorse the bioengineered collagen scaffolds for applications in tissue regeneration without scar in chronic burn wounds.

Industrial expansion has increased the discharge of contaminated wastewater. Wastewater can be treated by adsorption with petroleum-based hydrogels but the materials are not biodegradable and therefore cause secondary toxic waste. In this work, hydrogel composites are prepared based on non-biodegradable polyacrylamide and biodegradable materials of cassava starch (CS) and poly(vinyl alcohol). The effect of CS content on the porous structure is studied. The highest water absorption capacity of 74 g g −1 is obtained from a hydrogel 30 wt% of CS. Within 4 h, the hydrogel effectively adsorbs the cationic dyes methylene blue (MB) and crystal violet, and the anionic dyes congo red and reactive orange. The maximum adsorption capacity toward MB is 993 mg g −1 . Experimental data indicate a monolayer adsorption via chemisorption. Silica-coated ZnO photocatalyst particles are synthesized via a sol-gel method and coated on the outer surface of the hydrogel. Under sunlight, the hydrogel composite degrades almost 90% of adsorbed dye. The hydrogel composite is capable of effective photodegradation for at least three cycles under artificial UV irradiation and four cycles under sunlight, but adsorption capacity remains higher than 80% at the eighth cycle. The hydrogel composite also shows antibacterial activities, indicating an additional beneficial property for industrial wastewater treatment.
