Nanotechnology

Nanotechnology is a scientific and engineering field

By creating "things" at the level of atoms and molecules - usually materials and devices. 

A nanometer is one billionth of a meter: ten times the diameter of a hydrogen atom.

The average diameter of a human hair is 80,000 nanometers.

The normal laws of physics and chemistry no longer apply to such scales. For example, materials' properties can vary, such as color, strength, conductivity, and reactivity.

 

Nanotechnology is known to improve energy efficiency, help clean up the atmosphere, and solve major health problems. It is said that it is able to greatly increase production output at drastically lower costs. Nanotechnology products, according to proponents of nanotechnology, will be smaller, cheaper, lighter, and more practical and require less energy and fewer raw materials to make them.

 


“COVID 19 “

COVID-19) is a newly discovered coronavirus, which is an infectious disease, most people with COVID-19 experience mild to moderate symptoms.

Respiratory disease recovers without the need for special treatment.

Older people are more likely to develop serious diseases.

Underlying medical conditions such as cardiovascular disease, diabetes,

 Chronic respiratory disease and cancer. The easiest way to stop and slow 

After an infected person coughs, sneezes, sings, talks or breathes,

COVID-19 spreads from person to person, primarily via the respiratory pathway. 

A new infection occurs when other individuals who are in close contact with the infected person get into the mouth, nose, or eyes of virus-containing particles exhaled.

By an infected person, either respiratory droplets or aerosols. Respiratory

Droplets can evaporate into droplet nuclei, which remain suspended for long periods of time in the air.

Coronaviruses (COVID 19) is a broad family of viruses that cause diseases ranging from common colds to more serious diseases such as Extreme Acute Respiratory

 

 Virus corona is consider new strain that has not been seen in humans until and Now and has induced viral pneumonia is the new in2019 

It was first connected to Wuhan's South China Seafood City market, in December 2019.
