The Nano Materials Research Division at the Korea Institute of Materials Science (KIMS), led by Dr. Tae-Hoon Kim and Dr. Jung-Goo Lee, has successfully developed a groundbreaking grain boundary ...

SIMS imaging of lithium-ion migration within a solid electrolyte specimen. Grain boundaries resistant to ionic diffusion have created an uneven 6 Li distribution. Quantitative analysis found that ...

There is a correlation between bulk mechanical properties of polycrystalline materials and the strength of individual grain boundaries at the micro- or nano-scale. The strength of the grain boundary ...

Metal alloys can fail unexpectedly in a wide range of applications -- from jet engines to satellites to cell phones -- and new research helps to explain why. Metal alloys can fail unexpectedly in a ...

Integrated circuits have become increasingly more reliable as the technology has progressed, but even a perfectly produced processor operated under the most rigorously maintained environment will fail ...
