Particle adhesion to the vasculature depends critically upon particle/cell properties (size, receptors), scale/geometric features of vasculature (diameter, bifurcation, etc.) and local hemodynamic factors (stress, torque, etc.) Current investigations using in vitro parallel-plat…

Thermoplastic polyolefins (TPOs), blends of polypropylene, elastomers and other additional filers, are non-polar materials with low energy surfaces. Surface pretreatment is required to enhance the surface energy and to achieve adequate paint adhesion to the TPO surface. In this …
The development of glass substrates for use as an alternative to printed circuit boards (PCBs) attracts significant industrial attention, because of the potential for low cost but high performance interconnects and optical connection. Electroless plating is currently used to dep…
This thesis investigates the underlying causes of friction and ine ciency within an internal combustion engine, focusing on the ring-liner conjunction in the vicinity of the power-stroke top dead centre reversal. In such lubricated contacts, friction is the result of the interpl…
Adhesive joining is an attractive alternative to conventional joining methods, such as welding and mechanical fastening. The benefits of adhesive bonding include: the ability to form lightweight, high stiffness structures; joining of different types of materials; better fatigue …
U.S. spends approximately 20 billion/year on asphalt pavements with disproportionately high maintenance costs of 9.3 billion/year. Better performance of asphalt pavements is crucial to reducing these maintenance costs. During the past two decades significant advances have been m…
The effects of direct plasma chemistries on carbon removal from silicon nitride (SiNx ) and oxynitride (SiOx Ny ) surfaces and Cu have been studied by x-photoelectron spectroscopy (XPS) and ex-situ contact angle measurements. The data indicate that O2 ,NH3 and He capacitively co…
There is currently a lack of methods to prepare molecularly well-defined model substrates for studies of cell adhesion and cell migration. Most of these studies are performed on substrates that are coated with extracellular matrix proteins to which cells can attach. The limitati…
Famed entomologist and Harvard alum Thomas Eisner (AB’51, OEB Ph.D.’56) once said, “Insects are the most versatile of evolutionary innovators. Pick an insect at random, and chances are there is something about the way it feeds or defends itself, or reproduces, that is unique”. T…
