Adsorption Desorption

Experiments have been conducted to examine the adsorption/desorption characteristics of 1,1-dichloro-1-fluoroethane (HCFC-141b) by granular activated carbon (GAC) and extruded activated carbon. HCFC-141b is currently deemed an excellent replacement for CFC-11, a foaming agent widely used in the rigid polyurethane foam industries. Experimental results of adsorption and desorption were analyzed in terms of the equilibrium capacity, time to reach equilibrium and desorption efficiency of the adsorbent, and with the aim of assessing the viability of using both adsorbents for possible HCFC-141b recovery. The results have clearly revealed great potential for both adsorbents for this purpose.

Radiative Model

AbstractIn order to achieve a nickel-like X ray laser scheme we need a tool to determine the parameters which characterise the high-Z plasma. The aim of this work is to study gold laser plasmas and to compare experimental results to a collisional-radiative model which describes nickel-like ions. The electronic temperature and density are measured by the emission of an aluminium tracer. They are compared to the predictions of the nickel-like model for pure gold. The results show that the density and temperature can be estimated in a pure gold plasma.

Lattice Images

Since phase contrasts of STEM images, that is, Fresnel diffraction fringes or lattice images, manifest themselves in field emission scanning microscopy, the mechanism for image formation in the STEM mode has been investigated and compared with that in CTEM mode, resulting in the theory of reciprocity. It reveals that contrast in STEM images exhibits the same properties as contrast in CTEM images. However, it appears that the validity of the reciprocity theory, especially on the details of phase contrast, has not yet been fully proven by the experiments. In this work, we shall investigate the phase contrast images obtained in both the STEM and CTEM modes of a field emission microscope (100kV), and evaluate the validity of the reciprocity theory by comparing the experimental results.
