Researchers at Princeton, Yale, and the University of Zurich have proposed a theory-based approach to characterize a class of metals that possess exotic electronic properties that could help scientist...
Incubation-time Based Approach for Dynamic Yielding of Metals
dynamic yielding incubation-time approach failure criteria
2012/9/24
Transition of the materials from elastic to plastic state is modeled by incubation-time based criterion. This approach is similar to the structural -temporal theory for brittle solids fracture develop...

We determine the dynamic magnetization induced in non-magnetic metal wedges composed of
silver, copper and platinum by means of Brillouin light scattering (BLS) microscopy. The magnetization is trans...
Graphene, a hexagonal sheet of sp2-bonded carbon atoms, has extraordinary properties which hold immense promise for future nanoelectronic applications. Unfor-tunately, the popular preparation methods ...
Negative refraction in natural ferromagnetic metals
Negative refraction natural ferromagnetic metals
