Question 1

What is the typical size range of a nanoparticle?

Accepted Answer

1 to 100 nanometers. Nanotechnology generally deals with structures sized between 1 and 100 nanometers. At this scale, materials often exhibit unique physical and chemical properties. One nanometer is equal to one-billionth of a meter.

Question 2

Who is famously known as the father of nanotechnology for his 1959 talk 'There's Plenty of Room at the Bottom'?

Accepted Answer

Richard Feynman. Richard Feynman suggested the possibility of manipulating individual atoms and molecules in his landmark lecture. He predicted that entire encyclopedias could be written on the head of a pin. His visionary ideas provided the theoretical foundation for the field.

Question 3

Which term was coined by Norio Taniguchi in 1974 to describe precision manufacturing at the atomic level?

Accepted Answer

Nanotechnology. Norio Taniguchi used the term 'nanotechnology' to describe the processing of materials atom by atom. He focused on the extra-high precision and ultra-fine dimensions required for such work. This was the first formal use of the term in scientific literature.

Question 4

What is the name of the allotrope of carbon that consists of a single layer of atoms arranged in a hexagonal lattice?

Accepted Answer

Graphene. Graphene is a two-dimensional material known for its exceptional strength and electrical conductivity. It is effectively a single sheet of graphite. This material is considered one of the strongest substances discovered so far.

Question 5

Which type of microscope is essential for visualizing surfaces at the atomic level by using a sharp probe?

Accepted Answer

Scanning Tunneling Microscope. The Scanning Tunneling Microscope (STM) allows scientists to see and manipulate individual atoms. It was invented by Gerd Binnig and Heinrich Rohrer, who won the Nobel Prize for it. This instrument is a cornerstone of modern nanotechnology research.
