A carboxymethyl cellulose hydrogel loaded with TiOnanoparticles for wastewater treatment is provided. The TiONPs@CMC hydrogel is made by a method including providing raw date fiber, bleaching the raw date fiber, delignifying the bleached raw date fiber, and then performing alkalization and etherification on the bleached raw date fiber to produce date derived CMC; followed by dissolving the CMC in calcium chloride to form a paste-like solution, adding TiONPs to the paste-like solution, and freeze-drying the paste-like solution to obtain the TiONPs@CMC hydrogel. The TiONPs@CMC hydrogel is effective for degrading pathogens contaminating wastewater and preventing biofilm formation in wastewater systems.

Wound dressings fabricated from a polymeric mixture of cellulose acetate and hyaluronic acid embedded with copper oxide and/or magnesium oxide nanoparticles and a method of making the wound dressing. The method includes combining hyaluronic acid and deionized water to form a first mixture, combining cellulose acetate and acetone to form a second mixture, combining the first and second mixtures to form a third mixture of hyaluronic acid, cellulose acetate, deionized water and acetone, separately adding at least one of a copper acetate solution and a magnesium chloride solution to the third mixture to form a fourth mixture, adding sodium hydride to the fourth mixture to form a final mixture, and drying the final mixture to form a film used for the wound dressing. Different weights of copper oxide and magnesium oxide can be chosen to achieve a certain morphological appearance. The wound dressing is a promising option for wound healing.

A thermochromic ink and, particularly, to a thermochromic ink produced by combining an anthocyanidin extract with alginate. The thermochromic ink can be used for authentication purposes produced by combining an anthocyanidin (ACYD)-basedL. var.extract with an alginate (ALG). To increase the anthocyanidin/alginate ink stability, a mordant (ferrous sulfate) can be used to link the anthocyanidin biomolecules with the alginate.

A photochromic material can include nanoparticles of rare-earth activated strontium aluminate (NRESA) embedded into polylactic acid (PLA). In some embodiments, the photochromic material may be transparent. In other embodiments, the photochromic material may be scratch resistant. In some embodiments, the photochromic material may be configured to form an anti-counterfeiting substance. The photochromic material may exhibit a green coloration after exposure to ultraviolet (UV) light. The NRESA may have a diameter of about 10 nm to about 15 nm. The electrospun photoluminescent nanofibrous film may have a fiber diameter of about 50 nm to about 200 nm.
