Abstract: Nanotechnology can improve the mechanical barrier and the antimicrobial (which will not allow the invasion of microorganisms in the food, increasing the food barrier properties, hence can be a very promising material for food packaging. Nanomaterials will keep the food fresh in the food packaging design. Silver nanoparticles and nanoclay represent most of the nanoempowered food packaging available on the market others like zinc oxide and titanium share little of the current market. Zinc oxide enhances nutritional values in food products by adding nutrients. It helps improve the flavour, storage properties, appearance, and texture of the food. Titanium dioxide is used for food safety purposes since it prevents food from spoiling and increases the food’s shelf life. In current food packaging, these nanomaterials are used to grant antimicrobial capacity and further develop hindrance properties, broadening packaged food’s shelf life and newness. Nanofood packaging has many benefits for general wellbeing. The related harmfulness of migration, particularly in acidic conditions, is extensive. The use of nanomaterials because of their physical and chemical properties makes them broadly accessible in numerous areas. This review summarizes the antimicrobial packaging application, nanomaterials synthesis, and nanomaterial properties in food packaging.

Abstract: Chitosan has become the most known and second abundantly available recyclable, non-hazardous and eco-friendly biopolymer after cellulose with several advantageous biomedical, agriculture, and wastewater treatment applications. As nanotechnology has progressed, researchers have begun incorporating chitosan-based carbon compounds into various compounds, elements, and carbonaceous materials to increase their efficiency and biocompatibility. Chitosan carbon compounds have also been used directly in many applications due to their inherent chelating and antibacterial features and the presence of customizable functional groups. This review widely discusses- the properties and synthesis of chitosan and chitosan composite. It also discusses the modification of chitosan with different compounds, metals, carbonaceous materials, and agriculture residues to allow their use on an industrial scale. Recent advances in the use of chitosan in biomedical, agro-waste management, agriculture, wastewater treatment, and a few other applications (such as food packaging, cosmetics, and the textile and paper sector) are briefly discussed. Furthermore, this analysis reveals that chitosan and its composite materials are potential, low-cost products for environmental clean-up that can be made with basic manufacturing procedures.

Abstract: Magnesium-sulfur batteries have developed as a new and emerging technology benefiting from high energy density, low cost, reasonable safety, and excellent energy storage due to the high natural abundance of electrochemically active materials and low dendrite formation in magnesium. Here we report various enhancement strategies and also focus on using carbon electrodes, coating layers of carbon over the cathodes, carbon nanotubes, reduced graphene oxide, graphene-carbon nanotubes in magnesium-sulfur batteries because of its high conductivity and improved overall electrochemical functioning of the magnesium-sulfur battery. However, developing these batteries remains challenging due to significant problems caused during theirs operation, such as self-discharge, Mg-anode passivation, insufficient reversible capacity, low sulfur cathode utilization, and rapid capacity loss. We acknowledge the synthesis of non-nucleophilic electrolytes, both situ characterizations of anode or electrode reactions and kinetics, strategic development of sulfur-based cathodes and carbon electrode in Mg–S battery as a critical factor toward improvement in cycle performance, specific capacity, overpotential and working voltage, and confinement of Mg-PS polysulfide, to limit the shuttling of polysulphides, steady accumulation and desolvation of magnesium alent ions to create a magnesium-conducting surface electrode interphase(SEI). We also present a detailed description of the Mg–S battery, its challenges, future research directions for the practical implementation of the various developed electrolyte and electrodes.
