  • Experimental study of film formation on metals in hydrocarbons

    The purpose of this study was to provide certain quantitative information on the, corrosion of metals in insulating oils, and simultaneously to throw more light on the anions present in hydrocarbons. The process under study was the deposition of metal salts on a metal surface in contact with oil containing an aliphatic acid in solution. The metals that gave positive effects were copper, lead, and zinc. The aliphatic acid was carbon 14 labeled, and the small amounts deposited were determined by measurement of radioactivity of the metal, samples. The deposition was effected in one group of experiments by chemical action and in another group by electrochemical action.

  • Dual-mode piezo-on-silicon resonant temperature and humidity sensor for portable air quality monitoring systems

    This paper demonstrates a dual-mode, micromachined temperature and relative humidity (RH) sensor platform using two ZnO-on-silicon, lateral-mode bulk acoustic wave (BAW) resonators. A moisture-insensitive reference resonator is utilized in conjunction with an identical, humidity functionalized resonator to yield a thermally compensated RH sensor. The reference sensor exploits the dual-mode response of fundamental and higher order in-plane resonance modes in the range of 30-100 MHz to eliminate the RH sensor dependence on temperature. Hygroscopic polyethyleneimine (PEI) is deposited on annexed sensing platforms of the BAW resonator to enable operation from 20 to 92 %RH with high Q in air. A humidity sensitivity of 1.2 kHz/%RH from 20 to 60%RH and 14 kHz/%RH from 60 to 92%RH is measured at room temperature for the RH sensor which, combined with the reference sensor, occupies a total area of .053 mm<sup>2</sup>.
