Azo dye, [SiO2 (OH)2 ]9 molecular ring, and single-walled carbon nanotubes (4,4) SWCNT were considered like an axle, a wheel, and stoppers, respectively. The combination of the azo dye on the [SiO2 (OH)2 ]9 molecular ring with (4,4) SWCNTs may be thought of as a non-covalent system in UV light-isomer-machine. A new molecular motor system that runs like a hinge motion is demonstrated like light-powered molecular hinges. A new molecular motor system that acts as a hinge motion has been demonstrated and introduced as light-moving molecular hinges. By emitting various ultraviolet, visible lights, the [SiO2 (OH)2 ]9 molecular ring in the system can be reversed with the various dumb-bell size on one side attached halogens and fixing it on the other side of the (4,4) SWCNTs surface, a variety of systems in a wide variety of ultraviolet sensors can be designated to a better model of molecular machines and can be used for drug delivery of some antibiotics that are difficult to administer by straight injection. Molecular machines containing a wide variety of ultraviolet sensors have been designed with the combination of azo derivatives formed by replacing different halogens with hydrogen in the azo dye on the [SiO2 (OH)2 ]9 molecular ring to the (4,4) SWCNTs surface.
Delta variant of covid-19 study, and why it is a concern: An overview

COVID-19 is caused by the virus SARS-CoV-2 that belongs to the Coronaviridae groups. The subgroups of the coronavirus families are α, β, γ, and δ coronavirus (the four general human coronaviruses). Representative coronaviruses consist of NL63 coronavirus (human) and porcine transmissible gastroenteritis from the Alphacoronavirus genus; mouse hepatitis coronavirus (MHV), bovine coronavirus (BCoV), severe acute respiratory syndrome coronavirus (SARS-CoV), and Middle East respiratory syndrome coronavirus (MERS-CoV); avian infectious bronchitis virus (IBV); and porcine δ-coronavirus (PdCoV). This work exhibits, δ-coronavirus spikes are fundamentally and evolutionally more similar related to α-coronavirus spikes than to β-coronavirus or γ-coronavirus spikes due to the receptor recognition, membrane fusion phenomenon, and immune evasion behavior.
