Transforming Agro-Industrial Waste into Bioplastic Coating Films.

Addressing the environmental impact of agro-industrial waste, this study explores the transformation of banana, potato, and orange peels into bioplastics suitable for thin coating films. We prepared six extracts at 100 g/L, encompassing individual (banana peel, BP; orange peel, OP; and potato peel, PP) and combined [BP/OP, BP/PP, and BP/OP/PP] formulations, with yeast mold (YM) medium serving as the control. Utilizing the spin-coating method, we applied 1 mL of each sample at 1000 rpm for 1 min to create the films.

Urea biosensors based in zeolites and chalcogenide-oxide semiconductor thin films as active materials: A review.

Diagnosis of renal failure by measuring urea levels has been a topic of intense study in recent years. A major focus has been on improving the sensitivity, linearity, precision, accuracy, and selectivity of biosensors for measuring urea. Although various materials have been used in the fabrication of urea biosensors, ceramics, and chalcogenides have been less explored in this field.

Study of CdS/CdS Nanoparticles Thin Films Deposited by Soft Chemistry for Optoelectronic Applications.

Chalcogenides semiconductors are currently being studied as active layers in the development of electronic devices in the field of applied technology. In the present paper, cadmium sulfide (CdS) thin films containing nanoparticles of the same material as the active layer were produced and analyzed for their application in fabricating optoelectronic devices. CdS thin films and CdS nanoparticles were obtained via soft chemistry at low temperatures.
