In this special guest feature, Santina Russo from CSCS writes that scientists are using the “Piz Daint” supercomputer at CSCS to investigate a perovskite material for use in solar cells. In recent ...

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 ...

Engineering ceramics such as zirconia (ZrO 2), alumina (Al 2 O 3), silicon nitride (Si 3 N 4), silicon carbide (SiC) etc. have been used more frequently in engineering applications as engineers and ...

Metalworkers and metallurgists have long appreciated the ability to tailor the performance characteristics of steel (an alloy of iron and carbon), including their strength, hardness, ductility and ...
