ABSTRACT
The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is considered as serious global threat of this time and greatest challenge for recent days. Several approaches have been carried out in this direction to fight against COVID-19. Among these, nanotechnology is one of the promising approach to face these challenges in the current situation. Recently, graphene-based nanomaterials have been explored for COVID-19 due to its unique physicochemical properties. This mini review provides a recent progress in graphene-based nanomaterials and its applications for diagnosis, detection, decontamination, and protection against COVID-19. Further, main challenges and perspective for fundamental design and development of technologies based on graphene-based materials are discussed and suitable directions to improve these technologies are suggested. This article will provide timely knowledge and future direction about this wonder materials in various biological applications.
ABSTRACT
The study examined the relationship between COVID-19: a Situation Analysis of Nigeria’s Economy. To carry out this study, one specified research objective was set in which the null hypothesis was formulated and used for the study. The research design for this study is an Export Facto design. Data for the study were extracted from government official documents and they were subjected to The Philip Peron (PP) test analysis using Bartlett-kernel procedure to determine the bandwidth for the test. The study concluded that in the long-run, impact of COVID-19 on Nigeria's economy is positive as expected, indicating that a unit decrease in oil price as a result of the COVID-19 increases Nigeria’s economy stress by 0.005 units. The result is also statistically significant. And also, recommended that the government should intensify efforts to curb the spread and effect of the virus to promote a healthy environment where economic activities can continue. A moratorium should be given to some SMEs, industries, businesses to help their business sprout again. Because of them has used the business working capital/operational cost for family feeding during the lock-down. The government can give interest-free loans to help some stressed business swing into operation. © 2020, Hampstead Psychological Associates. All rights reserved.
