Creator:: Santoso, Elisabeth
Abstract:: The fouling characteristics of cooling tower water containing various corrosion inhibitors and other additives on heat transfer surface have been investigated. Corrosion inhibitors investigated included zinc-chromate and phosphates. In addition, additives including polyacrylate and phosphonate (HEDP and AMP) were used to determine their effectiveness as antifoulants. The tests were conducted...

Abstract:: The Brownian motion of micron-scale particles reflects the viscoelastic response of the local environment of the medium. Tracking the thermal fluctuations of these particles is a measure of the rheology of the material at the microscopic scale. This technique is called passive microrheology. Microrheology has been developed to assess the...

Creator:: Asumpinpong, Kasidid
Abstract:: Single-layer and three-layer microchannel adsorption devices were fabricated by procedure that was newly developed. Aluminum was chosen for metal housing while the adsorption pair was silica gel and water. Each adsorption layer contained two layers of 250 μm-thick silica gel. Both silica gel layers opened to the same layer of...

Creator:: Christensen, Kristi
Abstract:: The purpose of this research was to examine the ability of the cold water, green, marine, macroalga Acrosiphonia coalita to take up and metabolize polycyclic aromatic hydrocarbons (PAH) from seawater. Axenic suspension tissue cultures of the alga were contacted with seawater containing PAH in sealed experimental vessels. Uptake time courses...

Creator:: Carvalho, O. Quinn
Abstract:: Heterogeneous catalysis modulates the rate and selectivity of reaction processes by stabilizing a series of intermediate states on solid surfaces, facilitating the production of many commodity chemicals modern society relies upon. Conventional, thermal catalytic processes—conducted at elevated temperatures and pressures—source thermal, mechanical, and chemical potential energy from carbon-hydrogen bonds— combustion...

Creator:: Mohamed, Omar M.
Abstract:: This thesis experimentally determines the feasibility to creating C4 to C10 hydrocarbons from CO2, CO, H2, H2O and CH4. This is done in two steps, the initial step is the formation of ethylene through DC electrical glow discharge at ambient pressure while the second step is through temperature pulse controlled...

Creator:: Lahm, Lawrence
Abstract:: The fouling of cooling tower water was investigated as a function of heater surface temperature and water quality. In particular, the effects on fouling of the addition of calcium in excess of the amounts required for saturation were examined. First, the average bulk water temperature was 97 ± 1 degree...
