Pre-electrolysis at the boiling point in open Pd|D2O cells is an effective method to activate a palladium cathode, which can produce excess power in subsequent electrolysis in closed systems for several months. The reproducibility is 23/45. Another characteristic of excess heat is the apparent resistance of electrolytic cell changes irreversibly with temperature.

We present a lattice Boltzmann method that has the capability of simulating thermodynamic multiphase flows. This approach is fully thermodynamically consistent at the macroscopic level. Using this method, the liquid-vapor boiling process, including liquid-vapor formation and coalescence together with a full coupling of temperature, is simulated.

In this paper, a numerical scheme has been developed for primary and secondary fluids adopting Euler–Cauchy method to find the temperature distribution of the primary fluid relative to the secondary fluid and vice–versa and to obtain an optimum boiling length of the tube in the vertical inverted U–tube steam generator (UTSG).

The very low vapor pressure of ionic liquids is challenging to measure. At elevated temperatures the liquids might start to decompose, and at relatively low temperatures the vapor pressure becomes too low to be measured by conventional methods. In this work we developed a highly sensitive method for mass loss determination at temperatures starting from 350 K. This technique is based on an alter...

AIM To assess the influence of silane evaporation procedures on bond strength between a dental ceramic and a chemically activated resin cement. MATERIALS AND METHODS Eighteen blocks (6 mm Chi 14 mm Chi 14 mm) of ceramic IPS Empress 2 were cemented (C and B) to composite resin (InTen-S) blocks using a chemical adhesive system (Lok). Six groups were analyzed, each with three blocks divided acco...

Abstract: In this study an appropriate computational approach was presented for estimating the boiling temperatures of 41 different types of olefins and their derivatives. Based on the guidelines of this approach, several structural indices related to the organic components were applied using graph theory. Meanwhile, in addition to evaluating the relation between the boiling temperatures of ole...

There are many astringent date cultivars at maturity (Full coloration) around the world. These fruits could not be consumed at this stage due to the presence of soluble tannins. Growers have to wait until about 50% of these bunches reach to the rutab stage (ripening) which represents a major source of fruit loss due to abscission, birds attack and pathogens. Furthermore, late-maturing cultivars...

Joule heat generated by resistive elements of cryogenic micro- and nanodevices often originates boiling the cooling liquids (helium, nitrogen). The article proposes an experimental method to explore dynamics formation development a single vapor bubble in liquid sensing temperature change superconducting thin-film microbridge being state with phase slip center or line. It serves both source for ...

Self-rewetting fluids are commonly used in heat pipes, but their performance is not well understood pool boiling. Here, we performed boiling of n-butanol-water mixtures on thin titanium foil and utilized synchronous high-speed IR video cameras to capture transient temperature fields bubble dynamics. At the onset nucleate boiling, self-rewetting offered higher nucleation site density smaller dia...
