Mapping of polycrystalline nanoscale structure

5 June 2009

Researchers at Carnegie Mellon University has successfully attempted mapping of polycrystalline nanoscale structure. Katayun Barmak and Thomas Nuhfer have become the first material scientists across the world that successfully map polycrystalline structure. Barmak, a renowned professor of material science and engineering at the University has led to achieve the novel mapping process.

Barmak and her colleagues found that some of the physical properties within nanoscale structure changes with time. Actually a polycrystalline structure has three dimensions and these dimensions are known as atoms, ions and molecules. All the three dimensional patterns may have a number of orientations in space and Barmak have successfully map the boundaries between these dimensions.

Barmak has analyzed a number of times the crystalline materials and that too thousand time smaller and found that even a minute grain of boundaries can significantly obstruct the important physical parameter such as electrical charge if these polycrystalline materials are subjected to electrical field.

The novel research led by the professor of material science and engineering and her colleagues at Carnegie Mellon University can enhance the designing and tailoring of conductive materials such as copper so that these matters become more conductive in future.
