#1. What does “nano” mean?
The prefix “nano” comes from a Greek word, which means “dwarf”. In the International System of Units, the prefix “nano” means one-billionth, or -9 10 . If we have a nano “something” we have one billionth of that something including meters (length), seconds (time), litres (volume) and grams (mass) to represent what is understandably a very small quantity.
#2. Who used the term Nanotechnology first?
“He coined the term nanotechnology to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer: Nanotechnology mainly consists of the processing of separation, consolidation, and deformation of materials by one atom or one molecule.” N. Taniguchi, “On the Basic Concept of ‘Nano-Technology’,” Proc. Intl. Conf. Prod. Eng. Tokyo, Part II, Japan Society of Precision Engineering, 1974.
#3. When semiconductors are reduced to nanometres they become pure conductors...
When semiconductors are reduced to the nano form their chemical properties change significantly and they become insulators, as there is no more space for free electrons to move.
#4. What are quantum dots?
Quantum dots (QDs) are man-made nanoscale crystals that that can transport electrons. When UV light hits these semiconducting nanoparticles, they can emit light of various colors. These artificial semiconductor nanoparticles that have found applications in composites, solar cells and fluorescent biological labels.
#5. Of which components consists Carbon?
It sits right at the top of the periodic table, wedged in between boron and nitrogen. Atomic number 6, chemical sign C. Six protons, six neutrons, six electrons. It is the fourth most abundant element in the universe after hydrogen, helium, and oxygen, and 15th in the Earth’s crust. While its older cousins hydrogen and helium are believed to have been formed during the tumult of the Big Bang, carbon is thought to stem from a buildup of alpha particles in supernova explosions, a process called supernova nucleosynthesis.
#6. A nanometer and a meter can be understood as the same size-difference as between
A nanometer and a meter can be understood as the same size-difference as between golf ball and the Earth.
#7. Is it true that fingernails grow one nanometer per second?
Yes is the correct answer!
#8. When did Ruska, Binnig and Rohrer won the Nobel Prize in Physics “for their design of the scanning tunneling microscope”?
The Nobel Prize in Physics 1986 was divided, one half awarded to Ernst Ruska “for his fundamental work in electron optics, and for the design of the first electron microscope”, the other half jointly to Gerd Binnig and Heinrich Rohrer “for their design of the scanning tunneling microscope.”
