    A heat transfer model for tubes immersed in gas fluidized beds (1985)
    Hoboken, NJ : Wiley-Blackwell

    Notes: A model for local heat transfer between a gas-fluidzed bed and a submerged tube is proposed based on combined dense-phase and lean-phase transport. The heat transfer process during dense-phase contact at the tube surface is modeled by packet renewal mechanism and the transfer process during lean-phase contact by fluid convection mechanism. The model predictions show good agreement with experimental local and average heat transfer coefficient data for horizontal tubes.

    Properties and processing characteristics of dielectric-filled epoxy resins (1989)
    Brookfield, Conn. : Wiley-Blackwell
    Polymer Composites 10 (1989), S. 205-214 
    Details
    ISSN: 0272-8397

    Notes: A family of casting composites, epoxy resins with mineral fillers, having a range of electrical properties, are being developed. In such composites, the dielectric constant is controlled primarily by varying the filler material in composition and proportions. The present work reports on the mechanical properties of composites made with two types of filler, an alumina powder (XA3500 from ALCOA) and a BaTiO3/TiO2 ceramic powder (ATD-50 from Ampex). Dependence of mechanical properties on curing agents was also determined. Filler contents from 0 to 40 percent volume were used. Epoxy systems contained single epoxy resin with both amine and anhydride hardeners. Processing of the anhydride-cured systems was easier than that of the amine-based systems because of their lower viscosity and longer gel time of the former. However, the anhydride-cured systems required higher processing temperatures. Curing kinetics and molecular bonding were investigated using a combination of differential scanning calorimetry, dynamic mechanical thermal analysis, and scanning electron microscopy. Activation energies of 11.2 kcal/mole and 12.1 kcal/mole were obtained for the curing of the amine-based and the anhydride-based composites respectively, and a small difference in the glass transition temperature was also observed. These effects can be attributed to the difference in the structure of the curing agents. The epoxy resin cured with NMA is less ductile compared with those cured with MTHPA or MHHPA due to slight chemical modification on the ring structures. This dependence of ductility on curing agent was observed in specimens with different filler contents. Although the presence of the filler materials was found to enhance the mechanical properties of the epoxy, the fracture mode in these materials is still brittle.

    Effects of plasticizer desorption, temperature, and pressure on the permeability of saran (1987)
    Brookfield, Conn. : Wiley-Blackwell
    Journal of Vinyl and Additive Technology 9 (1987), S. 129-132

    Notes: Work has shown that (1) the permeability of saran film increases exponentially with increasing temperature due to activation energy, (2) permeability of saran film decreases slightly with increasing pressure-but to only a very slight extent, (3) microwave radiation does not affect permeability as long as the film is not heated during treatment, and (4) low amounts of liquid additives correlate with lower permeability. It is suggested that the barrier property of saran film can be improved without sacrificing the processing ability.

    Solute-membrane interactions in hyperfiltration (1987)

    Notes: The performances of several composite membranes (PEC-1000, Teijin, HR-95, HR-98) and one asymmetric membrane (Solrox SC-200) in hyperfiltration are compared at 25°C using different aqueous feed solutions (0.1M and 0.5M NaCl, 0.5M 1,3-and 1,4-dioxan, 0.1M benzyl alcohol and 2-methoxybenzyl alcohol, 1,2- and 1,4-butandiol, and Triton feed solution). The effects of solute dissociation, polarization, and hydrogen bonding ability on solute permeability are discussed; steric effects are also being considered. Strong solute-membrane interactions are exhibited in hyperfiltration by systems with distinct hydrogen bonding capabilities of the solute with functional sites of the membrane matrix. Knowledge of solute-membrane interactions can be useful for elaborating separation and transport mechanisms.

    A study on the plasma polymerization of some cyano-containing compounds and their electrical properties (1989)
    Bognor Regis [u.a.] : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: Plasma polymerization of some cyano-containing organic compounds was carried out at 13.56 MHz from the gas phase. The resulting polymer films were smooth and pinhole free. The electrical conductivities of the polymer films varied from 10-12 to 10-7 S cm-1 depending upon which cyano-containing monomer was used. The Al/polymer film/ITO (indium-tin oxide) sandwich cells made from the films demonstrated a photovoltaic effect, and some of them showed good rectifying behavior. Infrared spectroscopy (IR) and ultraviolet spectroscopy (UV) were utilized to characterize the structure of the product polymers. The effects of the original structure in the starting monomers on the structure of the resulting polymers are investigated. The influence of incident light intensity on the photovoltaic characteristics was also investigated.

    Notes: The interfacial tensions of immiscible binary blends of poly(dimethyl siloxane) (PDMS) and polybutadiene (PBD) have been determined as a function of molecular weight and temperature. The technique employed for these measurements takes advantage of recent advances in the determination and analysis of pendant fluid drop profiles. The experimental data are compared to the predictions of square gradient theories and theories based on the diffusion equation approach as developed by Helfand and co-workers. Qualitative agreement is obtained with both types of theory when the Flory-Huggins interaction parameter is taken to be comprised of two terms: a temperature independent term of entropic origin; and an enthalpic term that is inversely dependent upon the temperature.
