The vapour pressure of liquid nitrogen has been measured between 176°C and 148°C. The results are represented as a function of temperature by a formula, containing four constants.doi:10.1016/S0031-8914(53)80003-0A. MichelsT. WassenaarW. de GraaffChr. PrinsElsevier B.V.Physica...
liquid ammonia expands to850 timesits liquid volume at atmospheric pressure Thevapour pressure of ammoniais the pressure at which ammonia gas is inthermodynamic equilibrium with its condensed state. At higher pressures ammonia would condense . At this equilibrium condition the vapor pressure is thesatur...

Using the above mentioned criterion, helium and nitrogen combination has been chosen for cold tip temperatures in liquid nitrogen temperature range. The paper discusses the analytical approach and the results indicate that the presence of vapour compression cycle with isentropic expansion, operating under...
Within the MBE reactor the pressure of Bi is high at 330 °C and a sufficiently large Bi beam equivalent pressure (BEP) is required to avoid total evaporation of Bi droplets. If the Bi BEP drops well below the Bi desorption rate, none of the bulk Bi will remain. That many nanowires...
