Maritime Ports May Be the Next Deployment for Hydrogen Fuel Cells

Hydrogen fuel cells are being used in a variety of ways to provide efficient, pollution-free power: mobile lighting systems, forklifts, emergency backup systems, and light-duty trucks, to name a few. Providing auxiliary power to ships in berth may be added to that list soon. Joe Pratt (Energy Systems Engineering and Analysis Dept.) and Aaron Harris [...]

Hoboken Hopes To Reduce Power Outages With New ‘Smart Grid’ System

Mayor Says New System Will ‘Keep Everyone Safer Through Next Storm’ HOBOKEN, N.J. (CBSNewYork) – Officials are hoping to reduce power outages during future storms in Hoboken by designing a “smart grid” system using military-inspired technology. The Hudson River came pouring into the streets of Hoboken when Superstorm Sandy struck cutting off road access, putting [...]

Hoboken, New Jersey, Mayor Zimmer Announces Infrastructure Initiatives to Address Flooding, Water, and Power Systems

Hoboken, NJ – Wednesday, May 15th, 2013 Hoboken Mayor Dawn Zimmer announced a partnership with North Hudson Sewerage Authority (NHSA) to build Hoboken’s second wet-weather flood pump in order to alleviate Hoboken’s 200-year flooding problem. The pump, with a capacity of 50 million gallons per day, would further alleviate flooding in Western Hoboken. The City [...]

Sandia Develops a Synthesis of Quantum Dots that Increases the Quantum Yield to 95.5%

White light-emitting diodes (LEDs) based on blue indium-gallium-nitride (InGaN) LEDs that excite yellow-green-emitting yttrium-aluminum-garnet: cerium phosphors (YAG:Ce, a nonhygroscopic, chemically inert inorganic scintillator) have a cold white emission that can be made warmer with the addition of a red-emitting component. Unfortunately, red emitters that satisfy all criteria for use in solid-state lighting (SSL) applications are [...]

Phonon Scattering by Crystallographically Coherent Domain Walls

Sandia staff members Jon Ihlefeld (in the Elec­tronic, Optical, & Nanostructured Materials Dept.) and Stephen Lee (in the Semiconductor Material and Device Sciences Dept.) in collaboration with professors Patrick Hopkins (Univ. of Virginia), Bryan Huey (Univ. of Connecticut), and Darrell Schlom (Cornell Univ.) recently published “Effects of coherent ferroelastic domain walls on the thermal conductivity [...]
