Mixed nanoparticle films of SnO1.8: Ag prepared by the gas phase condensation method using an aerosol route have been used for the detection of CO and CH4. Particle size as estimated by transmission electron microscopy is 20 nm for both SnO1.8and Ag nanoparticles. The gas-sensing behavior of the films for these gases has been studied in detail as a function of Ag concentration in the films. A study has been made in order to distinguish the size effect and specific surface area effect in the ethanol gas-sensing behavior of SnO1.8: Ag mixed nanoparticle films. This distinction, which has not been possible using the traditional methods of the sensor fabrication, gives evidence of the dominance of size effect of the metal dopant over the surface area effect in the gas sensing of the films. The sensors show also an increased sensor signal with increase of Ag concentration in the films for CO and CH4. It is observed from the comparative study of the sensing behavior of SnO1.8: Ag films for CO and CH4that the sensors are more sensitive towards CO as compared to CH4. The mixed nanoparticle films were also used for the detection of CO at 100 ppm level.

Fractionation Procedure

The influence of the surface area on the performance of plasma filters for dead-end mode of filtration is presented in this paper. Theoretical analysis of the dead-end filtration was performed and verified experimentally (using ENKA cellulose-diacetate PF-100 membranes) in respect to β-lipoprotein. The theoretical model allows to optimize the course of the transmembrane pressure during plasma fractionation procedure in dependence of the surface area, initial concentration of macromolecules, total volume of the feed and membrane structure. The results indicate that the surface area effect is an important factor in the operation of membrane plasma fractionation and should be considered in the design of the plasma fractionation filter.
