plastics are well-established for convenient and safe packaging and distribution of food and feed goods. at present, this special sector of the plastic market displays remarkably increasing quantities of its annual production. caused by the ongoing limitation and strongly fluctuating prices of fossil feedstocks, classically used for plastic production, there is an evident trend to switch toward...

In response to the dynamic changes in current consumer demand and market trends, the area of Active Packaging (AP) is becoming increasingly significant. Principal AP systems include those that involve oxygen scavenging, moisture absorption and control, carbon dioxide and ethanol generation, and antimicrobial (AM) migrating and nonmigrating systems. Of these active packaging systems, the AM vers...

Polymer nanocomposites incorporating metal or metal oxide nanoparticles have been developed to improve their characteristics (flexibility, gas barrier properties, antimicrobial or antioxidant properties, etc.). Among them silver nanoparticles are used because of their antimicrobial effect in many daily life materials, i.e. food packaging. However, there is not any reference to the migration of ...

Tribological behavior of Cu-MoS2 and Ag-MoS2 nanocomposite lubricant was studied. Cu nanoparticles produced by electrical explosion of copper wires and Ag nanoparticles prepared by electrospark erosion were employed as metal cladding modifiers of MoS2 nanolamellar particles. The tribological tests showed Cu-MoS2 and Ag-MoS2 nanocomposite lubricants changed the friction coefficient of the initia...

In response to the dynamic changes in current consumer demand and market trends, the area of Active Packaging is becoming increasingly significant. Unlike traditional packaging, which must be totally inert, active packaging is designed to interact with the contents and/or the surrounding environment. Active packaging refers to the incorporation of additives into packaging systems with the aim o...

Based on the principle of fluorescence enhancing, by the strong and specific interreaction between iodide (I(-)) ions and nanoAg on the surface of graphene quantum dots/Ag (GQDs/Ag) nanocomposite, we propose a simple label-free and turn-on method for the detection of I(-) ions with high selectivity and sensitivity by using fluorescent GQDs/Ag nanocomposite in aqueous media.

Ag@α-Fe₂O₃ nanocomposite having a core-shell structure was synthesized by a two-step reduction-sol gel approach, including Ag nanoparticles synthesis by sodium borohydride as the reducing agent in a first step and the subsequent mixing with a Fe+3 sol for α-Fe₂O₃ coating. The synthesized Ag@α-Fe₂O₃ nanocomposite has been characterized by various techniques, such as SEM, TEM and UV-Vis spectrosc...

The interest for the development of new active packaging materials has rapidly increased in the last few years. Antimicrobial active packaging is a potential alternative to protect perishable products during their preparation, storage and distribution to increase their shelf-life by reducing bacterial and fungal growth. This review underlines the most recent trends in the use of new edible coat...

Active agar (AG) bilayer films with bioactive capability and electrochemical writing property were developed for improving the postharvest quality of banana. The antioxidant antimicrobial capacity enhanced incorporation red radish extract (RRE) neem essential oil (NEO) into AG lower layer. barrier mechanical properties, retention total anthocyanin NEO content in effectively improved addition Ti...
