We have succeeded in synthesizing AC waveforms with the rms voltage of greater than 10 V using an AC-programmable Josephson voltage standard (AC-PJVS) system. The system has a NbN-based junction array, which is cooled with a compact cryocooler. The array is composed of total 524 288 junctions, enabling to generate arbitrary signals with the maximum output level of about 17 V for 15.9 GHz microwave...
In this paper we describe a simple method to measure the thermal conductivity and thermal diffusivity of three related biochemicals: an amino acid, a peptide and a protein in aqueous solution using a liquid calorimeter chip. The measurements are performed by applying an AC voltage to an integrated heater at 10 mHz and 1 Hz and measuring the output voltage of the thermopile. The biochemicals solution...
