of Informatics and Radioelectronics, Belarus) present the second expanded edition of a reference handbook that collects some 2000 entries defining and describing significant terms in nanoscience and nanotechnology, ranging alphabetically from "Abbe's principal," which states that the smallest distance that can be resolved between two lines by optical instruments is proportional to the wavelength and inversely proportional to the angular distribution of the light observed, to the "Zundel ion," the smallest protonated water cluster.
For projectile energies sufficiently above the Coulomb barrier, the elastic angular distribution is dominated by a diffractionlike pattern.
