APTM with normal cerebral MRI had a low rate of conversion to CDMS in this long-term study. To date, there have been only a few follow-up studies that have addressed this issue.

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. In this review, synthesis technologies and microstructure of chitosan composites and its carbon materials in biomedical, agriculture, and wastewater treatment concerning the administration of abiotic stress within plants, water accessibility for crops, scheming food bear pathogens, photothermal cancer rehabilitation, and heavy water pollutants absorption and removal methods are widely deliberated upon, with a relevant discussion of the techniques that can be used to put these into action. Chitosan is also utilized in miscellaneous applications, including the food sector and cosmetics. Overall, chitosan-based carbon compounds promise to extend agricultural practices while also addressing health concerns in an environmentally friendly manner.

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.

Bio-derived activated porous carbon is readily used because it exhibits high surface area, excellent electrical conductivity, high stability, environment-friendly nature, and easy availability. All of these properties make it a unique and a perfect applicant for energy storage devices. Biowastes such as corncobs, walnut shells, human hair, jute, oil seeds, and bamboo are utilized as precursors in manufacturing porous carbon. The use of bio materials is preferred because of their abundance and biodegradable nature. The production of porous carbon was carried out through pyrolysis with the help of acid, primarily KOH, as the active substance. The ambient temperature for conducting pyrolysis is 400-800oC. Pyrolysis can be either fast or slow, with fast pyrolysis being helpful in most experiments. Food wastes like peels and shells are among the most significant biowaste sources alongside farm waste like rice husks, coconut shells, etc., which are not just waste and can be utilized for sustainable living. The porous carbon is formed from food waste from toxicity reducer in wastewater to for a supercapacitor or a bio anode in a microbial fuel cell. It is oneway sustainable development and is now highly economical. Moreover, in scientific aspects, their validity in a field and lowered expenses in some cases, the benefits of their usage may vary. This paper aims to extensively review all of the research conducted for Bio-waste utilization and its conversion to porous carbon for further use in super capacitance applications
