Topological photonic polycrystal (TPPC) implemented in photonic integrated circuits (PIC) and its structural details. (A) Diagram of HTP-PIC displaying edge and corner states.

Hybrid Photonic polycrystals with a synthetic hybrid dimension enable versatile control of edge channels and corner modes in multiple frequency bands.

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 ...

However, high-nickel NMC cathodes formed using the standard method are agglomerated into polycrystal structures that are rough and lumpy. This meatball-like texture has its advantages in regular NMC.

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 ...

The biocompatibility, or reaction of some zirconia ceramics, in particular 3mol% yttria stabilised tetragonal zirconia polycrystal (3Y-TZP) to physiological environments or simulated physiological ...
