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.
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 ...
