HAMANTASHEN

Left: A secondary electron HRSEM micrograph of a single-crystal Ni particle on a (111) YSZ substrate. The Ni particle is oriented with the (111) plane parallel to the substrate surface and is surrounded by grains of a second phase containing mostly Cr and O.

In this work agglomeration of a Cr-doped Ni film ("solid state dewetting") on YSZ substrates was carried out at 800 ˚C, in Ar/H₂, for 72 hr to form equilibrated Ni(Cr)-YSZ interfaces. During Ni agglomeration, Cr segregated to the Ni surface and reacted with oxygen from the environment.

The shape is achieved by folding in the sides of a circular piece of dough, with a filling placed in the center.

In this case the dough is made of butter, sugar and flour and the filling is dates spread. The baking was carried out at 180 ˚C, in air, for 10 min.
