Thermoelectric materials are playing an increasingly significant role in the global effort to develop sustainable energy technologies. Consequently, the demand for materials with greater thermoelectric efficiency has stimulated the development of state-of-the-art interstitially doped skutterudite-based materials. However, since intermetallics are often embrittled by interstitial substitution, optimal skutterudite-based device design, manufacture,...
A constrained thin film desorption scheme has been experimentally tested to determine the desorption rates for water from an aqueous lithium bromide mixture through a confining membrane. Variable conditions include the inlet concentration, pressure differential across the membrane, and channel height. Desorption takes place in a channel created between two...
A numerical model has been developed to simulate the firing of an inkjet printhead.
The model evaluates the heat generation and diffusion within the thin film structure, the
phase change and vapor bubble growth in the ink, and the subsequent flow of ink from the
orifice. The heat transfer is...
Technologies such as avionics and power electronics are driving the demand for thermal management schemes towards high heat fluxes and low surface temperatures. Typically, these applications require the dissipation of heat fluxes in the rage of 100-1000 W/cm² while maintaining surface temperatures lower than about 85 °C. Phase-change heat transfer...
Nisin, an antimicrobial peptide used in food preservation was
evaluated for thermal stability. Nisin retained antimicrobial
activity after having been heated at 121°C for seven hours.
Anhydrous nisin and concentrated nisin solutions (5-10 mg/ml) were
still active after having been heated up to 190°C or 230°C. When
exposed to high...
This report establishes an industry knowledge base for existing anchoring and mooring techniques as applied to wave energy conversion (WEC) devices in and around Oregon. This report on anchoring and mooring techniques is derived from the cumulative experiences of engineers and scientists with many years of experience analyzing, designing and...
The thermal wave technique has been explored for the use of liquid thermal conductivity measurement and flow property diagnostics in this dissertation. For liquid thermal conductivity measurements, an experimental technique based on the thermal wave approach is developed. A stainless steel strip functions as both a heating element and a...
In light of the current world-wide energy situation,
the utilization of the immense reserves of geothermal
energy is being actively pursued. The thermal energy contained
in a geothermal reservoir is mainly stored in rocks,
but is also held in liquid water and/or steam. The generation
of electrical power from these...
