The lattice dynamics of lithium nitride (Li<Subscript>3</Subscript>N) under high pressure are extensively investigated to probe its phase transformations by using the pseudopotential plane-wave method within the density functional theory. A new second order α↦α<Superscript>′</Superscript>-Li<Subscript>3</Subscript>N phase transition is identified for the first...</subscript></superscript></subscript>

This paper presents the description and operation of a solar-powered ice-maker with the solid adsorption pair of activated carbon and methanol. A domestic type of charcoal is chosen as the adsorbent, and a simple flat-plate collector with an exposed area of 0.92 m2 is employed to produce ice of...

Measured values of temperature and pressure of pentane in the collection system of a laboratory model solar thermal water pump are reported. In one set of experiments the pentane was merely heated without tapping the vapour for pump operation and in the other actual pump operation was performed....

A solar thermal water pump using a flat-plate collector with n-pentane as the working fluid is described. A heat-transfer analysis has been carried out for this system with account for all heat losses. Variations in temperature and pressure of pentane in the collection system with time are...

A solar adsorber with glass tube insulation used in a solar adsorption cooling system is proposed and investigated. The adsorber is a metal tube packed with activated carbon methanol pair surrounded by a vacuum tube glazing. A mathematical model, which accounts for the heat and mass transfer of...
