The combination of two techniques, viz., thermal desorption mass-spectrometry and ion implantation, makes it possible (through variation of implantation doses in a wide range and with different steps) to establish the interrelation between the quantity of implanted deuterium, the retention coefficient, and the kind of desorption spectrum.
Sorption and desorption coefficients of solvent and Py molecules were measured respectively during dissolution of films, and found to be between 10−7 and 10−6 cm2 s−10−6
The results of experiments show that the novel system has improvements in the coefficient of performance, the mass of desorption and desorption rate, and the characters of the solar adsorption refrigeration system can be a benefit to further application.
Theory and experiments on the (non-equilibrium) stripping potentiostatic method for evaluation of the diffusion coefficient and desorption isotherms of hydrogen in α-Pd are discussed.
Literature values for the sticking coefficients of CO and oxygen and the desorption temperatures of CO on Pd hkl) and Pt hkl), are also included in Table S1.
U b Loss coefficient from the bottom of the adsorber-collector, W K−1. U L Global loss coefficient from the adsorber-collector surfaces, W K−1. U t Loss coefficient from the top of the adsorber-collector, W K−1. T s1 Temperature at start of desorption, K. T s2 Temperature at start of adsorption, K. W v Wind velocity, m s−1.
In this study, a new model to describe the time-dependent diffusion coefficients during desorption was developed.
Ediff must be smaller than the energy of desorption for diffusion to occur, otherwise desorption processes would dominate.
In the process of dynamic desorption, the concentration and the volume of desorption solution were investigated.
