In each case, microscopic physical details of the layers sculpt the reflection patterns, yielding unique color palettes, iridescence and metallic qualities.
Their findings add to a growing body of evidence for the microscopic physical conditions behind sonoluminescence — astonishing for a table-top experiment, but not sufficiently extreme to fuel ongoing speculations of nuclear fusion reactions.
The growth reflects an emerging need to understand microscopic physical and chemical processes, which are fundamental to further improve the macroscopic performance of construction materials.
Metamaterials have microscopic physical properties highly analogous to real materials, since their characteristic frequencies behave as equivalent energy levels, providing an efficient route to deal with stacked meta-atoms with strong interactions.
The coefficient of restitution (COR) is one of the microscopic physical properties of maize that must be specified to use EDEM software to perform numerical simulations to support the design of parts used in maize seeding and harvesting machines.
They also confirm the large entropy change of ΔStrans∼42.5 J kg−1 K−1 (see Supplementary Fig. 1) associated to this solid solid phase transition and whose microscopic physical origin can, in principle, be made up of configurational, rotational and vibrational contributions39.
