    Monitoring of Running-in of an EHL Contact Using Contact Impedance

    Running-in is an important process for elasto-hydrodynamic lubricated contacts, which affect both service life and operating performance. However, the possibilities of monitoring running-in are still poor. The...

    Effect of volatile organic contamination on head-disk interface tribology and a method for its reduction

    Volatile organic contamination is known to be one of the factors to cause the failure of head-disk interface (HDI). Therefore, reduction of its harmful effects and improvement of the stability and reliability ...

    Precise measurement of quadrupole moment of8B by use of a modified β-NMR

    The nuclear quadrupole moment of8B(I π=2+,T 1/2=769 ms) has been determined by use of a modified β-NMR detection as |Q(8B)|=68.3±2.1 mb. A field gradient was obtained in a single crystal Mg at room temperature.
