Activated carbon (AC) was recognized by many researchers as useful substance in adsorption of impurities. Several processes involved in the production of AC which were carbonization, crushing, and activation process. Carbonization of carbon required high temperature up to 900oC. Then the carbon will be crush to a desired size for activation process. Activation of carbon can be either chemical activation, physical activation or combination of chemical and physical activation which called physiochemical activation. The mechanism adsorption of AC commonly due to its micropore present in the carbon or the weak vander waals forces which can attract the impurities. Activated carbon have multiple function in human daily life. This study will be discuss the function of AC in the production face mask, water filtration and air filtration.

Abstract The COVID 19 disease caused by SARS-CoV-2 virus has become a subject of international concern due to its contagious nature and mortality rate. The lack of any definitive treatment also contributes to the severity of the disease. Identification of susceptible dental patient is the first and most important step of all preventive protocols. Categorization of the patients through a questionnaire will help the dentist to follow and modify preventive protocols accordingly. The various comorbidities which make an individual more susceptible to COVID 19 infection were identified through a thorough systematic review of literature. The questionnaire is derived from the studied literature and assigned a score. The generated aggregate of the score is used to categorize dental patient into low, medium and high risk groups. The reviewed literatures were collected from reputed online open access journals and subscribed journals. Dentists being the most vulnerable professionals during this COVID 19 pandemic should practice different preventive protocols. This is also required to limit nosocomial spread of infection through dental setup. Characteristics of the virus and the subsequent infection have also been discussed in brief in this systematic review for better understanding of the various protective protocols. Key words – COVID 19; Questionnaire; Susceptibility; Scoring; Dental patient; Prevention.

“…CFNs exhibit high conductivity [1], (electro-)chemical resistance [2], high surface area [3], flexibility [4], tunable pore-size and-shape [5,6]. These properties render CFNs applicable in filter media [7,8], wearable electronics [4], electromagnetic shielding [9,10], catalyst supports [11,12], and electrode materials [13].…”

Carbon nanofiber nonwovens are promising materials for electrode or filtration applications; however, their utilization is obviated by a lack of high throughput production methods. In this study, we utilize a highly effective high-throughput method for the fabrication of polyacrylonitrile (PAN) nanofibers as a nonwoven on a dedicated substrate. The method employs rotational-, air pressure- and electrostatic forces to produce fibers from the inner edge of a rotating bell towards a flat collector. We investigate the impact of all above-mentioned forces on the fiber diameter, morphology, and bundling of the carbon-precursor PAN fibers. The interplay of radial forces with collector-facing forces has an influence on the uniformity of fiber deposition. Finally, the obtained PAN nanofibers are converted to carbon nonwovens by thermal treatment.
