A Quantum Dot Energy Harvester
A new type of nanoscale engine has been proposed that would use quantum dots to generate electricity from waste heat, potentially making microcircuits more efficient.
Forget about leprechauns, engineers are catching rainbows
By creating a material that slows light, engineers open new possibilities in solar energy, military technology and other fields of research
Vortex pinning could lead to superconducting breakthroughs
A team of researchers from Russia, Spain, Belgium, the U.K. and the U.S. Department of Energy’s (DOE) Argonne National Laboratory announced findings last week that may represent a breakthrough in applications of superconductivity.
Artificial retina technology receives FDA approval
The U.S. Food and Drug Administration (FDA) granted market approval to an artificial retina technology today, the first bionic eye to be approved for patients in the United States. The prosthetic technology was developed in part with support from the National Science Foundation (NSF).
New room-temperature process could lead to less expensive solar cells and other electronic devices
Silicon, the material of high-tech devices from computer chips to solar cells, requires a surface coating before use in these applications. The coating "passivates" the material, tying up loose atomic bonds to prevent oxidation that would ruin its electrical properties. But this passivation process consumes a lot of heat and energy, making it costly and limiting the kinds of materials that can be added to the devices.
Superfast materials conducting materials
University of Utah engineers demonstrated it is feasible to build the first organic materials that conduct electricity on their edges, but act as an insulator inside. These materials, called organic topological insulators, could shuttle information at the speed of light in quantum computers and other high-speed electronic devices.
Supersonic pingpong bazooka blasts balls at Mach 1.23
WEST LAFAYETTE, Ind. - A Purdue University mechanical engineering technology professor has built a new air-powered bazooka that shoots pingpong balls at speeds faster than an F-16 fighter jet, blowing the doors off similar far less powerful devices peers use to explain physics properties.
New world record efficiency for thin film silicon solar cells
A remarkable step was achieved by the team led by Dr. Fanny Meillaud and Dr. Matthieu Despeisse with a new world record efficiency of 10.7% for a single-junction microcrystalline silicon solar cell, independently confirmed at Fraunhofer Institute for Solar Energy Systems (ISE CalLab PV Cells) in Freiburg (Germany).
Wireless power transfer technology for high capacity transit
The Korea Advanced Institute of Science and Technology (KAIST) and the Korea Railroad Research Institute (KRRI) have developed a wireless power transfer technology that can be applied to high capacity transportation systems such as railways, harbor freight, and airport transportation and logistics.
New lithium-ion battery design with improved capacity and recharge more quickly
New design uses silicon nanoparticles to improve capacity and recharge more quickly
