A Faster, Thinner Semiconductor
Published Wednesday, April 27, 2011Speed and scaling issues in silicon transfer are forcing researchers to invent new semiconductors and corresponding dielectrics to meet the requirements of the semiconductors industry. In order to continue this trend of scaling down the device size, future transistor materials need to be engineered at atomic and sub-nanoscales to perform functions...

Piezoelectric Paint Sensor
Published Sunday, April 24, 2011Problems with the gait and balance of a robot can interfere with its performance. Better understanding of how robot feet respond in contact with the ground can help correct such malfunctions. However, traditional piezoelectric sensors, which obtain ground reaction force data, are brittle, do not conform easily to the shape of the host structure,...

Ultra-Porous Silica Opal-Like Particles and Polymer/Silica Composites
Published Wednesday, April 20, 2011Opals are iridescent gems found in nature in which silica nano-spheres are packed together in regular microstructures. Their inverse replicas (i.e., regular arrangements of void spaces surrounded by solid silica walls), called “inverse opals,” are currently the object of active research due to their applications in photonic crystals, catalysis,...

A Revolutionary Touch Screen Interface for NewsStand
Published Sunday, February 20, 2011Smartphones—from Blackberries to iPhones to Androids—have revolutionized the way we access information. The latest news updates are only a few clicks away even if we are out and about. Similarly, mapping and navigational applications have changed how we interface with the world. A quick scroll moves us up from street level—city grids, states,...

Novel Phase Change Material Microcapsules
Published Wednesday, February 16, 2011Phase change material (PCM) microcapsules are granular substances with core and shell structures, where PCMs compose the core of the capsule. Fluids containing PCM microcapsules have received increasing attention in thermal management applications due to their ability to absorb and release large amounts of heat during phase change. However, the...

High-Resolution Parallel Scanning Laminar Optical Tomography
Published Tuesday, January 25, 2011Fluorescence imaging has been widely used in biomedical and clinical applications, and among many other fields. There are numerous situations where it is desirable to resolve 3D tomography (imaging by sections) of a sample. Most of the contemporary fluorescence tomography technologies fall in either the macroscopic or microscopic category...

Novel Vapor Compression Refrigeration and Heat Pump Systems
Published Sunday, January 23, 2011Vapor compression refrigeration and heat pump systems using natural refrigerants have gained increasing attention due to the global warming potential (GWP) of conventional hydrofluorocarbons (HFCs). Carbon dioxide (CO2) is a particularly attractive alternative to conventional refrigerants because it has relatively low GWP and no ozone depletion...

Roll-Bonded Heat Exchangers for Low Temperature Lift Energy Conversion
Published Wednesday, January 5, 2011Typical energy conversion—from power generation to heat pumping to air conditioning—utilizes a large temperature lift between heat source and heat sink. This is due, in part, to economic reasons. Energy conversion with a low temperature lift (ECLTL) between the heat source and heat sink requires a large heat transfer area and a high volume flow...
