A vertical axis wind turbine has been designed to electrify a novel kind of telecommunication tower. This paper presents the design of a generator for this purpose. The generator is a permanent magnet generator rated at 10 kW. It has an unusually large diameter to fit on the outside of the telecommunication tower. The generator has been designed by using a two-dimensional FEM model. Simulations show...
Both TiO2 and HfO2 are common materials for semiconductor fabrication that have shown memristive properties. Nanoparticles of these metal oxides have great prospect to provide nanoscale materials with tunable electronic properties for integration in advanced circuits such as neuromorphic networks based on memristive crossbar elements. We seek to take advantage of the unique interaction between the...
This paper presents a method for measuring the mechanical response of flagella on a single Escherichia coli cell to chemotactic agents using a microfabricated gold-coated silicon nitride cantilever. Changes in flagella motion on the cell immobilized near the free end of the cantilever due to changes in the chemical environment are sensed by a shift in resonance frequency (1st flexural-mode) of the...
Summary form only given. Bionanofabrication is a novel fabrication process that takes advantage of the specificity and catalytic efficiency of biological systems to create novel nanoscale structures. Polyhydroxyalkanoates (PHAs) are a family of aliphatic polyesters produced by a variety of microorganisms as a reserve of carbon and energy. PHAs can be combined from more than 100 different monomers...
