Prior studies of atomic - level grain boundary and segregation structures have been mostly focused on small - angle or special symmetrical tilt and twist boundaries with high symmetries and well - defined periodicities in artificial bicrystals.
The properties of the lattice are significantly affected by these «grain boundaries,» said Amin Salehi - Khojin, UIC assistant professor of mechanical and industrial engineering and principal investigator on the study.
This surprising result relied on our use of scanning tunnelling microscopy which allowed us to measure for the first time the three - dimensional structure of grain boundaries, including the precise angles between adjacent grains.»
Bagnold draws an analogy for this dispersive pressure (grains striking other grains) as snooker balls on an infinite table contained only by these shear boundaries.
Moreover, we studied how vacancies and adding new atoms to the structure can affect this lattice thermal conductivity and, finally, we propose the use of grain boundaries as a strategy to reduce this conductivity, according to our analysis on this field.
Computer simulations revealed that grain boundaries have a strong effect on magnetism.
Coincidentally, his team happened to solve the mystery while I working on the project: Marble varieties with smooth («granoblastic») grain boundaries would crack due to cycling thermal expansion and contraction, whereas marble varieties with rougher grain boundaries («xenoblastic») tended to resist grains shifting around and thus didn't crack as easily.
The most significant results were related to: i) the effect of vicinal surfaces on the film growth; ii) the films specifically grown for microwave applications: a clear correlation was demonstrated between the surface resistance, the losses and the concentration of high - angle grain boundaries; iii) the effect of film - substrate interdiffusion and its control by epitaxial buffer layer.
