People with an amputation at the hip or pelvis have the most difficulty returning to walking because their artificial limb (prosthesis) must replace the hip, knee, and ankle joints. Current prosthetic hip technologies barely meet the person's needs, leaving these amputees with few options. This project will build from current powered prosthetic knee technology (Össur POWER KNEE) to create a new level of prosthetic technology that powers both the hip and knee.
The proposed project would seek to develop a technology and identify adsorbents that are better able to remove impurities such as carbon dioxide (CO2), nitrogen (N2), and oxygen (O2) from biogas (mostly CH4, also referred to as natural gas) produced from landfills, using adsorption technology. Interns will be carrying out adsorbent screening, by determining kinetics and binary and multi-component adsorption behaviour. Promising adsorbents will then be selected and tested under cyclic conditions to determine their life cycle.
In the near future, a large quantity of satellites will be used to provide Internet and communication services everywhere on Earth. Most of these satellites will be moving at very high speeds on orbits close to Earth which implies the satellites will be moving relative to a user on the ground. As a result, the links between the ground and the satellite will experience frequent disconnections; a user will be disconnected from a satellite rapidly moving out of sight and the connection will be re-established with another satellite coming into view.
Conventionally, structural Al sheets are produced via casting thick ingots using Direct Chill (DC) technique, followed by an energy-intensive reduction procedure to the final thickness. A new production process developed by CASTechnology, termed Thin Strip Casting (TSC) technique, can directly output thin sheets, thus reducing the cost as well as the carbon foot print associated with the sheet production. The fundamental differences in the TSC vs.
Terahertz spectroscopy for material imaging/sensing and characterization has received a great deal of attention over the past decade. Terahertz (THz) electromagnetic waves have frequencies in the range of 1012 Hz. Terahertz spectroscopy and imaging has many applications ranging from security, communication, food production, quality control for pharmaceutical industries, and cancer diagnosis. In the heart of every terahertz spectroscopy imaging system, there is terahertz transmitter and receiver pair antennas.
Biomass is a key feedstock for the production of renewable fuels and chemicals with potential zero carbon emissions and at low cost. State of the art conversion of biomass to bio-fuels focuses on the pyrolysis of the feedstock at high temperature in conventional reactors. However, current technologies face many challenges to achieve lower costs than fossil fuels, higher yields, improved energy efficiency and product quality. This project aims to evaluate the production of renewable fuels from biomass using a dual spinning-disc reactor.
In order to investigate proteins in their natural environment one can attach tiny reporter molecules to them that can be traced with appropriate instruments. However, these small reporter molecules may often cause strong perturbations to the functionality of the proteins, or cannot be seen due to experimental restrictions like low concentrations. Bioorthogonal chemistry aims to eliminate such experimental restrictions by using as inert molecules as possible to see how proteins really work.
There is massive growth in the area of smart cities (e.g. sensors in streetlights), smart cars, and "smart people" (sensors on people, e.g. wearable computing). In some cities like San Diego, there are cameras and microphones in nearly every streetlight in the downtown core area. Most cars made now have one or more cameras in them, and numerous other kinds of sensors are being invented. These sensors are important regarding autonomous vehicles as well as technologies for extended human intelligence and safety.
The cellular clearance pathway autophagy is required for degrading toxic proteins and damaged organelles, but is disrupted in many neurodegenerative diseases. During induction many autophagy regulators quickly localise to membranes from the cytosol. The Martin lab has identified palmitoylation, which involves the addition of the fatty acid palmitate to cysteine residues, as a potential regulator to direct autophagy proteins to membranes.
The project will determine sliding wear behaviour of lightweight Al and Mg alloys for the continuously variable transmission (CVT) bore application and other engine applications. High temperature lubricated wear tests that simulate the actual operating conditions of CVT bore will be carried out. In addition, tests will be conducted at room temperature and under the dry conditions to benchmark wear resistances of different cast alloys and determine the wear mechanisms.
