ABSTRACT
At first sight, the outside world consists of big objects: buildings,
trees, mountains, etc. Yet upon a closer view, micro-and nanopar-
ticles play a significant part in our environment. The particles
surround us everywhere. We tread the earth that feeds us-it
consists of separate particles. The earth’s atmosphere and different
basins, soil and cosmic dust, clouds and granite, wood and clothes,
and brick and concrete are but separate examples of the prevalence
and importance of particles and nanoparticles. Food products-
bread, milk, meat, butter, and fish-can be regarded as micro-and
nanoparticle systems. A human being itself consists of particles
forming blood, bones, and tissues. Generally, any field of human
activity deals with numerous types of micro-and nanoparticles,
and therefore studying micro-and nanoparticles is the most
important mission of different sciences: physics, chemistry, biology,
mathematics, mechanics, and others.
