New quantum-dot LED design
By nestling quantum dots in an insulating egg-crate structure, researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated a robust...
Dye-sensitized solar cells more efficient than silicon cells
Dye-sensitized Grätzel solar cells have just set a new efficiency benchmark. By changing the composition and color of the cells, an EPFL team has...
Energy Savings through User-Controlled Efficient Lighting Systems
These days, in newer buildings it’s often hard even to find a plain old-fashioned light switch. Often, the only controls are automatic motion-detector switches...
Improved buildings for major reductions in their lifetime carbon footprint
The construction and operation of buildings accounts for approximately 40 percent of all U.S. emissions of greenhouse gases. The most-used building material in the...
Printable solar cells within reach in Australia
Victorian researchers have welcomed a $5 million grant from the State Government to help commercialize their revolutionary technology that uses printable light-sensitive ink to...
Thermoelectric materials for heating and cooling applications
For some years now, NASA has been using what are called thermoelectric materials to power its space probes. The probes travel such great distances...
New kind of optical fiber developed
A team of scientists led by John Badding, a professor of chemistry at Penn State , has developed the very first optical fiber...
Trap Light – Converting Waste Energy Back Into Light
Gionata Gatto and Mike Thompson created a new lamp that is completely powered by light energy absorbed from ambient sources.
By utilizing photo luminescent pigments...
New Highly Stable Fuel-Cell Catalyst Gets Strength from its Nano Core
Palladium core protects precious platinum; enhances reactivity/stability
Stop-and-go driving can wear on your nerves, but it really does a number on the precious platinum that...
A new class of light-emitting material could lead to cheaper OLEDs
Pure organic compounds that glow in jewel tones could potentially lead to cheaper, more efficient and flexible display screens, among other applications.
