    Differential microcalorimeter for liquid samples (1989)

    Notes: A microcalorimeter for liquid samples with high performance and low cost is described. It is essentially a differential apparatus in a "twin'' configuration with two cylindrical cells. Two resistive sensors, put in a Wheatstone bridge, are wound on the cells to measure the temperature difference between them. Sensitivity, response time, and calibration procedure are reported. As illustrative example, the specific heat of some liquids at two temperatures has been measured.

    Screening effect of impurities in metals: a possible explanation of the process of cold nuclear fusion (1989)

    Notes: Summary The screening length of the deuterium ion by surrounding electrons in a palladium metal lattice, as estimated using two approaches—viz. the Thomas-Fermi screening theory and the Debye screening theory for plasmas in metal—is found to be less than the interatomic separation of ordinary hydrogen molecules. This has important implications for the possibility of cold nuclear fusion at room temperature, since slight fluctuations in equilibrium conditions may drive the deuterons to fuse together. The relative magnitudes of screening length for the cold nuclear fusion regime and classical hot nuclear regimes (inertial and magnetic confinement) reveal that in the former a comparatively smaller amount of energy is needed to overcome the repulsive Coulomb barrier between two deuterium ions.
