Using state-of-the-art microscopy and simulation techniques, an international research team systematically observed how iron atoms alter the structure of grain boundaries in titanium. They were in for ...

Researchers have used electron energy loss spectroscopy to directly measure the coefficient of thermal expansion at grain boundaries in the polycrystalline material SrTiO3. The researchers identified ...

(Nanowerk News) The orientations of these infinitesimally small separations between individual “grains” of a polycrystalline material have big effects. In a material such as aluminum, these ...

Grain boundaries (GBs) in PSCs have been found to be detrimental to the photovoltaic performance of the devices. Numerous papers reported that the defects in perovskite GBs should be passivated by ...
