25.8Gbps Direct Modulation AlGaInAs DFB lasers were demonstrated for lower consumption in a wide temperature range. The DFB lasers achieved excellent eye opening from −20°C to 85°C at low current less than 56.5mA.
This paper reports the first demonstration of a biofuel cell (BFC) using trehalose found in insect hemolymph. The analysis results by liquid chromatography-mass spectrometry (LC-MS) showed that trehalose concentration included in cockroach hemolymph (CHL) was high enough to utilize as a source of power generation. The maximum power density of 6.07 µW/cm2 was obtained from CHL with added trehalase...
A prototype of thermoelectric module using oxide materials has been successfully fabricated, and the power generation characteristics have been examined in the high temperature region around 773 K (500 degC). Twelve couples of sintered p-NaCo2O4 and n-ZnO materials were connected via silver conducting strips with a planer arrangement jointed by using a diffusion welding technique under 16 MPa at 1023...
