Reflectance vs temperature measurements on thermochromic Cu(2)HgI(4) show phase transition hysteresis, which forms the basis for recording applications. Long term reflectance relaxation at room temperature has been noted, together with the ability to

The oscillations in low‐pressure plasma thermionic energy converters are ion acoustic oscillations that may be explained on the basis of an electron beam‐plasma interaction. A low‐energy beam is formed by the acceleration of electrons through a
