The whole world is facing a big crisis due to the spreading of newly detected novel corona virus 2019 (COVID ̶ 19). A huge number of people have already been infected since last 4 months. People are thinking about the prevention of infected individuals, vaccine, medical treatment, and other precautions. The governments of most countries including India have already taken several measures like lockdown, social distancing, closure of schools, colleges, religious gatherings etc., to reduce its spreading. India is a developing country and most of the people are having below the standard income. So the lockdown in India has affected the poor and middle income group people. In this article, we will discuss in detail on the societal effects in India due to COVID ̶ 19 pandemic. The effects of health, essential commodities, Indian economy, domestic violence, politics, and psychology on society due to COVID ̶ 19 will be elaborated in detail. The aim of this research is to have a clear understanding of the present societal scenario during lockdown, which may help the government for better management and prevention of the disease.

We report that the surface chemical properties of muscovite mica [KAl 2 (Si 3 Al) O 10 (OH) 2 ] like important multi-elemental layered substrate can be precisely tailored by ion bombardment. The detailed X-ray photoelectron spectroscopic studies of a freshly cleaved as well as 12-keV Ar + and N + ion bombarded muscovite mica surfaces show immense changes of the surface composition due to preferential sputtering of different elements and the chemical reaction of implanted ions with the surface.We observe that the K atoms on the upper layer of mica surface are sputtered most during the N + or Ar + ions sputtering, and the negative aluminosilicate layer is exposed. Inactive Ar atoms are trapped, whereas chemically reactive N atoms form silicon nitride (Si 3 N 4 ) and aluminum nitride (AlN) during implantation. On exposure to air after ion bombardment, the mica surface becomes more active to adsorb C than the virgin surface. The adsorbed C reacts with Si in the aluminosilicate layer and forms silicon carbide (SiC) for both Ar and N bombarded mica surfaces. Besides the surface chemical change, prolonged ion bombardment develops a periodic ripple like regular pattern on the surface.

The problem of facing difficulty to control the spreading of newly detected novel corona virus 2019 is a matter of attention throughout the whole world. The total numbers of infected individuals have already crossed 2 million throughout the world. The government of all the affected countries have already taken many measures like lockdown to stop the spread.Therefore, it is important to study the nature of growth and interpretations are necessary for taking needful by the government. In this paper, we have tried to interpret the spreading capability of novel corona virus in India taking into consideration of 21 days lockdown data.The prediction is based on the present number of available cases and number of new cases reporting daily. We have explained the number of infected people in India comparing with Italy, China, Spain, and USA data of 21 days individually after announcing lockdown. The plot of daily new cases with the number of days spent after lockdown is fitted by linear and polynomial function. The best fitted graph is chosen for interpretation and that is based on the parameters obtained from fitting. The forecast of maximum spreading possibility is discussed with linear and 4-degree polynomial fitting parameters. Finally, some further preventive measurements are also discussed.
