Henry's Law constants for pollutants from the wood industry in room temperature ionic liquids

Creator:: Wang, Fujun
Abstract:: The emission of organic compounds from wood manufacturing facilities is an important regulatory concern due to their effects on ambient air quality. Control technologies, such as oxidizers and biofiltration, are used to remove organics from air streams; however, most removal technologies have high costs or cause additional negative environmental impact....

The adsorption of human recombinant factor VIII in the presence of the nonionic triblock surfactant Pluronic® F-68 at the air-water interface

Creator:: Alkhatib, Aveen K.
Abstract:: The adsorption behavior of a human recombinant Factor VIII (rFVIII) in the presence of the nonionic, poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock surfactant Pluronic® F-68 was evaluated by dynamic air-water tensiometry. Surface tension kinetics were recorded for F-68 in the absence of protein at concentrations ranging from 0 to 10,000...

Aqueous-organic partition coefficients for Rn-222 and their application to Radon analysis by liquid scintillation methods

Creator:: Cantaloub, Michael G.
Abstract:: A method is described for determining the partition coefficient, K, for radon gas distributed between an aqueous phase and an organic solvent. The method uses sequential extractions of radon into equal volume aliquots of organic solvent. The radon-laden organic liquid is then counted on a liquid scintillation analyzer with alpha-beta...

Study of a constrained-film bubble absorber under cycle operating conditions

Creator:: Cardenas, Ruander
Abstract:: An experimental and numerical study of absorption of ammonia vapor bubbles into a constrained thin film of ammonia-water solution is presented in the context of a potential reduction in size of a heat-actuated heat pump component. A large-aspect-ratio channel with a depth of 600 µm restricts the thickness of the...

Nisin adsorption to PEO-PPO-PEO tri-block copolymer layers and its resistance to elution by fibrinogen

Creator:: Ryder, Matthew P.
Abstract:: While hydrophobic surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] (PEO-PPO-PEO) surfactant Pluronic® F108 are highly resistant to plasma protein adsorption, the antimicrobial peptide nisin has been observed to adsorb in multilayer quantities at such surfaces, and the PEO chains themselves suggested to inhibit nisin exchange by blood proteins. But...

Surfactant interactions with recombinant factor VIII at the air/water interface

Creator:: Chu, Liping
Abstract:: The surface tension kin'ti4tnd ste'dy state behavior exhibited by mixtures of selected surfactants with a recombinant Factor VIII (rFVIII) were evaluated with automated interfacial tensiometry. In particular, fresh solutions of rFVIII with different concentrations of Tween 80, sodium dodecylsulfate (SDS), or dodecyltrimethylammonium bromide (DTAB) were prepared and their surface tension...

Fibrinogen adsorption at heparinized silica interfaces : history dependence and adsorption time effects

Creator:: Lee, Hyo Jin
Abstract:: Heparin was modified with adipic diliydrazide and covalently linked to surface-activated silica. Contact angle measurements were made to determine changes in surface at various stages of the derivatization. Xray photoelectron spectroscopy was used to analyze the elemental composition of the surface at each step of immobilizing heparin as well and...

Transport of water and solutes from tile-drained fields in the Willamette Valley, Oregon : A field scale study

Creator:: Warren, Kristina
Abstract:: Tile drainage increases aeration in the root zone of poorly drained soils by accelerating water movement from the subsurface. Water movement is the main agent of chemical transport, either transporting soluble materials directly (e.g., nitrate) or by transporting the soil particles that bind adsorptive compounds (e.g., pesticides). The detection frequency...

Observations of gas flow in porous media using the light transmission technique

Creator:: Parker, Laila Belkov
Abstract:: A novel technique was developed for studying gas phase flow in unsaturated porous media. Carbon dioxide was pumped through a back-lit chamber packed with translucent sand which was variably saturated with water containing the pH indicator dye methyl red. As the carbon dioxide dissolved in the pore water, lowering the...

Fibrinogen adsorption at heparinized silica interfaces : history dependence and protein concentration effects

Creator:: Joshi, Omkar
Abstract:: Adipic dihydrazide-modified heparin was prepared and subsequently immobilized on surface-activated silica wafers. X-ray photoelectron spectroscopy (XPS) was used to quantify the elemental composition of the silica surface at each stage of activation and results showed that successful immobilization had taken place. Contact angle measurements were made to verify the high...
