Activated carbon is widely used for the purpose due to the large surface area available for adsorption or chemical reactions as a result of its high degree of micro porosity formed during carbonization. These materials are characterized by their extraordinary large specific surface areas, well-developed porosity and tunable surface containing functional groups.
16 electrode portable sensor that can be used for measuring the permittivity distribution of a mixture of 2 dielectric materials inside a closed vessel. Non-invasive, non-invasive, non-destructive and on-line technique. Integration intelligent electrode sensing circuit on each electrode sensor, (embedded on single plate).
Bioplastics from natural polymer and chitosan nanofillers were developed in accordance to extend the shelf life of food. Antimicrobial properties impart on this active packaging may be able to inhibit the microorganisms that may attack the food and it is suitable to be commercialized in the market.
