Development of an In-Situ Hydrothermal Dissolved Carbon Dioxide Sensor for Hydrothermal Environments
(2004)Hydrothermal systems at mid ocean ridges are a unique environment which connect the mantle, lithosphere, ocean, and biosphere in one complex system. Fluid chemistry is one key tool in understanding this environment, and ... -
Advances in In-Situ Calibration of Attitude and Doppler Sensors for Precision Oceanographic Submersible Navigation
(2005)This paper reviews the development and experimental evaluation of three techniques for estimating the alignment matrix of Doppler sonars, which are commonly used for precision navigation of oceanographic submersibles, ... -

Optimization of Long Range Electron Transfer for Solar Energy
(2006)Organic photovoltaics have the potential to become an accessible form of alternative energy production because of their ease of manufacture via traditional printing techniques and consequent low cost.1 However, the ... -
Storage of Captured Anthropogenic CO2 in Ocean Sediment
(2007)An essential problem of CO2 capture and storage technologies is finding sufficiently large geologic depositories to store the captured anthropogenic CO2. Additionally, due to the subsurface temperature profile of ... -
Electrification, Economic Development and Poverty Alleviation: Examining the Role of Macro-factors in Sri Lanka
(2007)Access to modern energy services is central to enhancing rural incomes, reducing poverty and achieving the Millennium Development Goals; however, it is not sufficient in and of itself (Barnes 1988; Barnes & Floor 1996; ... -
Dynamics of Wave-Current Boundary Layers over very Rough Boundaries
(2007)In this study, acoustic profiling techniques are used to resolve the two-dimensional spatial structures of the oscillating boundary layer in a phase-averaged sense over a wave orbital amplitude. The principal objective ... -
Link Foundation Fellowship Report
(2008-09)Peak hour electricity demand is associated with wholesale electricity prices that are sometimes more than 10 times higher than in off-peak periods. During these high-demand periods congested transmission lines and insufficient ... -
Optimizing the Performance of White Light-emitting Diodes for Energy-efficient Lighting
(2009)Over the past decade, high-brightness monochromatic (colored) LEDs have been replacing traditional incandescent light sources in certain niche applications such as traffic signals and “EXIT” signs. LEDs are able to save ... -
Final Report for the Link energy Fellowship
(2009-06)A sustainable energy future is critical for environmental and strategic reasons. Fossil fuel use has increased greenhouse gas emissions, and continued consumption could adversely change global climate. In addition, the ... -
An error threshold criterion for singular value decomposition modes extracted from PIV data
(2009-10-01)Singular value decomposition (SVD) is often used as a tool to analyze particle image velocimetry (PIV) data. However, experimental error tends to corrupt higher SVD modes, in which the root mean square velocity value is ... -
Semiconducting Nanowire Solar Cells for Enhanced Energy Harvesting
(2010)Solar cells are attractive candidates for generating clean and renewable energy. Nanowires (NWs) due to their unique electrical and optical properties offer new opportunities to solar cells for reduced cost and improved ... -
Link Foundation 2008‐2010 Energy Fellowship Report
(2010)I completed my PhD in Engineering and Public Policy at Carnegie Mellon University in May of 2010. My dissertation, entitled Developing Useful Long-term Energy Projections in the Face of Climate Change, seeks to identify ... -
Summary of work while a Link Energy Fellow
(2010)Electrons have an intrinsic property called spin, which is found in one of two states, an “up” and a “down”. The spin state of an electron can be observed and differentiated by applying an external magnetic field and ... -
Efficient and Cost Effective Solar Cells: New Materials for Improved Recombination and Charge Dissociation Losses in Organic Photovoltaics
(2011)Solar energy resources are vast: more energy hits the planet in one hour than humankind consumes in entire year. However, solar technologies have only been used to a limited degree in energy production thus far because ... -
Novel optical remote sensing technology for prediction of Harmful Algal Blooms
(2011)Harmful Algal Blooms (HABs) are outbreaks of planktonic algae that threaten public health, degrade aquatic ecosystems and cause major economic losses. Most HABs are detected only after they reach an advanced stage, when ... -
III-Nitride Optoelectronic Devices: From Ultraviolet detectors and visible emitters towards terahertz intersubband devices.
(2011)We review III-Nitride optoelectronic device technologies with an emphasis on recent breakthroughs achieved with the co-support of Link Foundation Energy Fellowship. We start with a brief summary of historical accomplishments ... -
Flame Synthesis of Iron Oxide Nanowires for Direct Coal Chemical Looping Combustion, and Tungsten Oxide Nanowires for Enhanced Photoelectrochemical Water Splitting.
