This video conference is an online #quiz based on #Multiple_choice_Questions (#MCQs) on #Nanosciences, #Nanomaterials and #Nanotechnologies.
#Nanomaterials are materials made up of particles having at least one dimension between 1 and 100 nm.
A nanometer (nm) is equivalent to one billionth of a meter, smaller than the wavelength of visible light and one hundred thousandth the width of a human hair.
Nanotechnology involves manipulating matter on a near-atomic scale to produce new structures, materials and devices. The technology promises scientific advancements in many industries such as medicine, consumer products, energy, materials and manufacturing. Nanotechnology is generally defined as technical structures, devices and systems.
#Nanomaterials are defined as elements whose length is between 1 and 100 nanometers.
At this size, materials begin to exhibit unique properties that affect their physical, chemical, and biological behavior. The research, development and use of these properties are at the heart of new technologies. As small as a nanometer is, it is still large compared to the atomic scale. An atom has a diameter of approximately 0.1 nm. The nucleus of an atom is much smaller: about 0.00001 nm.
In 1959, physicist and future #Nobel_prize winner #Richard_Feynman gave a lecture at the #American #Physical #Society entitled /"#There_Plenty_of_Room_at_the_Bottom./" The focus of his speech was on the field of #miniaturization and on the how he thought that man would create increasingly smaller and more powerful devices.
As the #surface_area_to_volume_ratio of nanomaterials increases, their surface becomes more reactive on itself and other systems. The size of nanomaterials plays an important role in their pharmacological behavior.
In 1986, #K._Eric_Drexler wrote "Engines of Creation/" and introduced the term nanotechnology.
Scientific research has really developed over the last decade. According to https://nomictimes.indiatimes.com, more than 10,000 nanotechnology patents have been filed with the U.S. Patent Office.
The global nanotechnology market is expected to reach around 125 billion by 2024, with startups and large companies including GE, Intel, Samsung, BASF and AkzoNobel developing products and solutions around nanotechnology.
