Pleasure And Pain: Study Shows Brain's 'Pleasure Chemical' Is Involved In Response To Pain Too Date: October 19, 2006 Source: University of Michigan Health System Summary:
Strategic material is any sort of raw material that is important to an individual or organizations strategic plan and to supply chain management. Lack of supply of strategic materials may leave an organization or government vulnerable to disruption of the manufacturing of products which require those materials. It can also refer to a group or department that manages these materials.
Even amorphous materials have some shortrange order at the atomic length scale due to the nature of chemical bonding (see structure of liquids and glasses for more information on non-crystalline material structure).hether a material is liquid or solid depends primarily on the connectivity between its elementary building blocks so that solids are characterized by a high degree of connectivity whereas structural blocks in fluids have lower connectivity (see figure on amorphous material states).
