Synthesis and function of bioactive, block copolymer surfactant constructs as relevant to the preparation of anticoagulant and antibacterial medical implant surfaces.

Creator:: Joshi, Pranav R.
Abstract:: Nisin, an antibacterial peptide proven to be an effective inhibitor of Gram-positive bacteria, was incorporated into novel block copolymer constructs and tested for retained antibacterial activity. Covalent coupling was achieved by chemical modification of the N-terminal isoleucine to introduce a thiol group. Thiolated nisin derivatives were then linked to poly[ethylene...

A force plate for measuring contact forces during dependent transfers onboard aircraft

Creator:: Schafer, Christopher A.
Abstract:: The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...

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...

Lead(II) Extraction with Electrospun Spiropyran Functionalized PMMA Nanofibers

Creator:: Fuchs, Brian K.
Abstract:: A system to reversibly extract Pb²⁺ ions from aqueous solutions using spiropyran functionalized nanofibers was proposed. Spiropyrans are photochromic compounds which undergo a conformational change that alters their physical properties and makes Pb²⁺ binding possible upon irradiation with UV light (365 nm). Irradiation with green light (525 nm) reverses this...

Effect of ambient environment on the fracture and fatigue properties of Zr-based bulk metallic glasses

Creator:: Philo, Sarah L.
Abstract:: The effect of ambient environment on the fatigue behavior of two Zr-Ti-Cu-Ni-Be bulk metallic glasses (BMGs) is examined in the present study. The first metallic glass, Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅, was tested to establish the presence of an environmental effect in the fatigue growth curve measured in ambient air. Fatigue growth curves produced...

Preliminary study on the effect of pH on the treatment of lead contaminated wastewaters with ozone

Creator:: Adolf, Ronald L.
Abstract:: Ozone was found to quickly reduce the concentration of lead in a prepared solution when the solution pH of said solution was greater than 7.0. When a solution having a pH of greater than 7.0 was filtered the concentration of lead was less than approximately 1.0 ppm. 1.0 ppm is...

Rheological Techniques in Characterization and Aiding in the Modification of Soft Matter

Creator:: Daalkhaijav, Uranbileg
Abstract:: Soft matter encapsulates a large array of materials ranging from electronics, plastics, and cosmetics to the biofluids making up all organisms. One of the most important properties of these materials that dictate their functionality is their rheology, which is the flow and deformation behavior in response to stress. The focus...

Investigations of gluten proteins from functional and historical perspective

Creator:: Zhang, Ying
Abstract:: Wheat (Triticum aestivum) is one of the world’s major staple food crops, with flour produced from starchy endosperm being used for breads, cakes, noodles and various other wheat-based foods. The unique bread making properties of wheat are primarily attributed to its gluten-forming storage proteins: gliadins and glutenins. This study investigated...

Heat transport at interface in the metal-organic-frameworks MOF-5

Creator:: Huang, Wenxi
Abstract:: The metal-organic–framework MOF-5 is used as an adsorbent in advanced systems for vehicular hydrogen storage that are currently under development. Presently, these systems are limited by poor thermal conductivity of the adsorption bed, and thus our research addresses how the interfaces between grains of MOF-5 can be engineered to improve...
