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.
The COVID-19 pandemic led to global lockdowns that severely curtailed economic activity. In this study, we set out to examine the social, economic, and environmental ramifications of the COVID-19 pandemic. This is a rare project that will have far-reaching consequences for the field. There are five sets of issues: short-term effects on oil and economic and agricultural policies, including regulations and COP26; long-term implications of monetary and fiscal intervention and investment in green agreements on future generations; prospects for further de-globalization and its effect on climate change and nature; and intergenerational environmental consequences, including debt and polling.
Schooling is important for the character preparing of person. There are various kinds of establishments accessible like private and public organizations, specialized foundations, These organizations are having the triangle of three principle columns; comprised of Teachers, Students, and Curriculum. There are two fundamental kinds of schools in Pakistan and everywhere on the world. One is public and other is non-public school framework. Presently a day’s non-public schools are getting more top pick and appealing for lion's share of the understudies because of their better training frameworks, test measures and information creation versus SEF schools, which similarly Free however wasteful are losing their fascination. Guardians want to send their kids in tuition based schools and evade SEF schools. The primary target of this examination is to research why individuals favor high charging tuition based schools to free SEF schools (That charge nothing)? We show that five principle factors arise as significant determinants of non-public school decision. These incorporate the financial status of the family unit, the level of a school's availability, the expense of tutoring, guardians' impression of school quality, and their view of the accessible business openings in the area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
