Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

Silicon Microrefrigerator [PDF]
IEEE Transactions on Components and Packaging Technologies, 2006 We fabricated a silicon microrefrigerator on a 500-mu m-thick substrate with the standard integrated circuit (IC) fabrication process. The cooler achieves a maximum cooling of 1 degrees C below ambient at room temperature. Simulations show that the cooling power density for a 40 x 40 mu m(2) device exceeds 500 W/cm(2). The unique three-dimensional (3-D)
