Acid-base properties of cyanobacterial surfaces II: Silica as a chemical stressor influencing cell surface reactivityDownload
Bacteria grow in complex solutions where the adsorption of aqueous species and nucleation of mineral phases on the cell surface may interfere with membrane-dependent homeostatic functions. While previous investigations have provided evidence that bacteria may alter their surface chemical...
High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...
This work provides a guideline for gecko inspired dry adhesive design and simulation. Mechanical property testing for several polymers commonly used in gecko adhesives (Kraton G1657 thermoplastic elastomer, ST-1060, and ST-1087 polyurethane elastomers) allowed hyperelastic and viscoelastic...
Ultrasound imaging has great potential in intraoral diagnosis, due to its portability, low cost, and low safety risks. A couplant is normally placed between transducers and tissues for better ultrasound image quality. If applied intraorally, the couplants should possess good stability in water,...
Examination of the Regulation of Phosphorylation Events in Macrophage Adhesion and Response to ZymosanDownload
Macrophages play a central role in innate immunity, most notably in tissue repair, phagocytosis of dead or infected cells, secretion of chemokine and cytokines at sites of infection, as well as the activation of other immune cells. These roles are highly dependent on their capacity to migrate...
Impact of an extracellular polymeric substance (EPS) precoating on the initial adhesion of burkholderia cepacia and pseudomonas aeruginosa
An alternative method of manipulating fragile MEMS devices during fabrication has been developed. A specialized manual or robotic end effector utilizing a gecko inspired adhesive can replace the slow and costly manual tweezers used by the MEMS foundry Micralyne Inc. Improving the adhesive...
Recently there has been great research interest in small soft particles because of their significance in both biology and industry. The term ‘particle’ here is defined as a deformable object with size in the range of nano- to micrometers. Many experimental efforts have been spent on investigating...
