The two-word name of this e-book can in basic terms supply a sign approximately its content material and method of the topic it bargains with. during time, the time period has steadily develop into a little bit blurred. the reason being effortless to determine: comparable difficulties are actually a growing number of usually studied by means of assorted branches of typical technology. The time period "mixed crystals" has received particular connotations in physics, chemistry, biology, and geology. One and a similar time period can now function a reputation for issues that are both no longer rather a similar or occasionally rather varied. And this can be accurately what occurred to the 2 phrases within the identify of the publication. one in all them, the time period "crystal", for which crystallography had an un- ambiguous definition, is now hired via biologists to explain the constitution of mobilephone membranes and via chemists who use it to indicate levels of polymer crystallinity. "Crystal" has hence turn into a large time period that could support describe any sturdy, or simply a condensed nation of a substance, if the forged has a suf- ficient measure of order within the association of its elements. however the e-book is termed "~lixed Crystals". the opposite notice in its identify, the adjective "mixed", has additionally built numerous meanings. it really is now suggestion ap- plicable to either homogeneous and heterogeneous platforms, that's, to crystals composed of alternative molecules and in addition to solids which are a mix of crys- tals with diverse buildings.
