Summary

Students of the subject will be introduced to fundamental laws and described parameters needed to a mathematic and physical description of a bulk solid behavior. Especially, a core of the subject will be turned to a storage system proposal. Latest knowledge of the rapidly growing branch: nanotechnology will be presented here also. There will be demonstrated measurement methods following interpretation of measured values in the subject. Ideal bulk solid; Definition of bulk solids state; Difference between fundamental material states; Bulk solids logistics; Criteria of transport/Processing system choice for Bulk solids.
