In the preceding issue of these PROCZEDINGS, the fact of characteristic frequencies for non-polar bonds was introduced into the Born-Karman heat capacity equations, which were then, with certain approximations, brought into a general simplified form for non-polar compounds.' With the aid of these simplified equations, the heat capacities of some organic solids will now be. calculated and compar...

in this investigation the silicate nano structure of mcm-41 has been used for the production of nanofluid.the particles have negligible heat conductivity and therefore by their dispersion in a base fluid likewater, it is possible to study the increase of heat conductivity due to the brownian motion effects. in thiswork a suitable apparatus for the measurement of heat conductivity has been built...

water and energy are key commodities utilized in the process industries.water minimization and energy minimization have been studied separately. in this paper, a new systematic design methodology has been developed for the simultaneous management of energy and water systems that also feature maximum re-use of water. in addition to allowing re-use of water, issues about heat losses inside unit o...

The ability to achieve near lossless coupling between a waveguide and a resonator is fundamental to many quantum-optical studies as well as to practical applications of such structures. The nature of loss at the junction is described by a figure of merit called ideality. It is shown here that under appropriate conditions ideality in excess of 99.97% is possible using fiber-taper coupling to hig...

The heat capacity Cp of an array of independent aluminum rings has been measured under an external magnetic field ~ H using highly sensitive ac-calorimetry based on a silicon membrane sensor. Each superconducting vortex entrance induces a phase transition and a heat capacity jump and hence Cp oscillates with ~ H . This oscillatory and non-stationary behaviour measured versus the magnetic field ...

Understanding the interaction between a fluid and a solid phase is of fundamental importance to the design of an adsorption process. Because the heat effects associated with adsorption are comparatively large, the assumption of isothermal behavior is a valid approximation only when uptake rates are relatively slow. In this article, we propose to determine when it is needed to choose the isother...
