The Ag-Ge-S system is among the best-performing active materials for a new class of high-performance electronic memory known as programmable metallization cells.[1,2] Memory switching in a programmable metallization cell relies on the electrochemical formation and dissolution of an electronically conducting filament within a solid electrolyte. In the Ag-Ge-S system, this electrochemical process...

In this study, composite packaging films were produced from relatively inexpensive materials including Whey protein isolate (WPI) and Persian gum (PG), supplemented with betanin nanoliposomes (NLPs). Using response surface methodology (central design), we investigated the effects of two variables (PG [0%–2% w/v] NLPs’ [0%–10% content) on physico-mechanical antioxidant properties film treatments...

 In this paper, a novel ternary nanocomposite namely reduced graphene oxide/hydroxyapatite/silver (rGO/HAP/Ag) was prepared by a simple hydrothermal method using graphene oxide nanosheets, Ca(NO3)2, (NH4)2HPO4, and AgNO3 as starting materials. The as-prepared nanocomposite was characterized by using various photophysical techniqu...

A Ni2+ based colorimetric probe based on glutathione-stabilized silver/copper nanoparticles (GSH-Ag-Cu alloy NPs) in an electrospun polymer matrix is reported. Glutathione-Ag-Cu alloy NPs were characterized by ultraviolet-visible spectroscopy (UV-vis), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The freshly synthesized GSH-Ag-Cu alloy NPs in a polymer matrix w...

Abstract The newly engineered functional systems of nanotechnology implemented in food packaging minimize product loss by extending shelf life. incorporation nanostructured materials into formulations enhanced the existing characteristics increasing specific surface area these biopolymers. Natural biopolymers were regarded as greener, more sustainable, and environmentally friendly materials. St...

The efficiency of combining high-pressure processing (HPP) and active packaging technologies to control Listeria monocytogenes growth during the shelf life of artificially inoculated cooked ham was assessed. Three lots of cooked ham were prepared: control, packaging with alginate films, and packaging with antimicrobial alginate films containing enterocins. After packaging, half of the samples w...

background and objectives: paper and paperboard packaging play an important role in safety and quality of food products. common bacteria of paper and paperboard food packaging could grow due to specific conditions included humidity, tem- perature and major nutrition to contaminate the food. the purpose of this research was to investigate numbers and the types of bacteria in the food packaging p...
