what they are, how they are made, what they are used for
WEBCarbon nanotubes are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene); they possess unique properties like high aspect ratio, mechanical strength, electrical and thermal conductivity, chemical stability, and a tip-surface area near the theoretical limit. They are one of the strongest materials known to man.
What is smart dust and how is it used? - Nanowerk
WEBSmart dust senses and records data about its environment such as light, temperature, sound, presence of toxins or vibrations, and transmits that data wirelessly to larger computer systems. Smart dust is a vision of the networked future where intelligent networks of trillions of miniscule sensors continuously feel, taste, smell, see, and hear ...

Electronegativity explained - Nanowerk
WEBElectronegativity is defined as the tendency of an atom to attract electron density, i.e., to polarize the chemical bond. The most widely used scale is the thermo-chemical Pauling’s scale, where electronegativities have units of eV 1/2. Electronegativity is a derived quantity, so it is not directly measurable.
Triboelectric effect - Nanowerk
WEBThe triboelectric effect is a type of contact electrification where materials become electrically charged after they have been in contact with another material and are then separated. Rubbing the two materials together enhances the contact between their surfaces, amplifying the triboelectric effect. Everyday examples include rubbing a glass rod ...
