2. lappuse - TLD's and TLD readers in use at program activities. Precision TLD's are pre-exposed to exact amounts of radiation by the National Institute of Standards and Technology, formerly the National Bureau of Standards, and provided to program activities for reading.
11. lappuse - The removal of particulates from lubricants is extremely important in the field of tribology ("The science of the mechanisms of friction, lubrication, and wear of interacting surfaces that are in relative motion.
7. lappuse - The discovery of quasicrystal structures in materials challenges a 100-year-old theory of crystallography and the existence of quasicrystals may make it possible to produce materials with radically different properties.
14. lappuse - The small-angle x-ray scattering facility is used by polymer physicists to obtain information on the microstructures of polymer blends to develop polymer alloy phase diagrams.
