Gelatin/carboxymethyl cellulose edible films: modification of physical properties by different hydrocolloids and application in beef preservation in combination with shallot waste powder.

In this work, a gelatin/carboxymethyl cellulose (CMC) base formulation was first modified by using different hydrocolloids like oxidized starch (1404), hydroxypropyl starch (1440), locust bean gum, xanthan gum, and guar gum.

Fabrication of binary g-CN/UU-200 composites with enhanced visible-light-driven photocatalytic performance toward organic pollutant eliminations.

In this study, g-CN/UU-200 heterojunction photocatalysts displaying superior photocatalytic activity for organic pollutant elimination under white LED light irradiation were fabricated an solvothermal method. The successful construction of a heterojunction between g-CN and UU-200 was evidenced by X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, and transmission electron microscopy. The improved photocatalytic degradation of rhodamine B (RhB) and tetracycline hydrochloride (TCH) over g-CN/UU-200 compared with that over the individual components can be attributed to the anchoring of the g-CN layered structure on the UU-200 surface promoting the decrease of the bandgap of UU-200, as confirmed by ultraviolet-visible diffuse reflectance spectroscopy, and to the light-induced charge separation efficiency stemming from a suitable heterojunction structure, which was revealed by photoluminescence spectroscopy and electrochemical analyses.
