By constructing a synthetic dimension combining momentum space and unit cell orientation space, we developed a configurable topological photonic polycrystal.

Some polycrystal grain boundaries feel the heat more than others Date: December 2, 2021 Source: Institute of Industrial Science, The University of Tokyo Summary: Researchers have used electron ...

Researchers from The University of Tokyo Institute of Industrial Science used electron energy loss spectroscopy to directly measure the coefficient of thermal expansion at grain boundaries in the ...

Tetragonal zirconia polycrystal (TZP) is commonly stabilized with 3% to 5% Yttria and has the finest grain size. Since they are almost entirely tetragonal, these zirconia grades have the maximum ...
