A new solar technology developed at RTI International (Research Triangle Institute) could make solar energy more affordable. RTI researchers have developed a new solar technology that could make solar energy more affordable by as much as 75% and thus speed-up its market adoption. RTI’s solar cells are formed from solutions of semiconductor particles, known as [...]
Sapphire Energy, Inc., one of the world leaders in algae-based green crude oil production, today announced the first phase of its Green Crude Farm, the world’s first commercial demonstration algae-to-energy facility, is now operational. The algae farm will grow to 300 acres, about a mile by ½ mile using 56 metric tons of CO2 a [...]
The photovoltaic solar cell business is closing in on dire economic straights. The economics for producing power are still far too expensive to compete with – almost all other forms of power generation. When news of a way to cut costs arrives – it matters. Over the long term solar will have a role in [...]
Development of Dysprosium-Free AC Servo Motor by SANYO DENKI
Researchers at the University of Cambridge have produced hydrogen from water using a newly designed and inexpensive cobalt catalyst. It’s noteworthy because the cobalt catalyst will work in conditions useful to industry. The catalyst uses simple fresh water, tolerates oxygen in the atmosphere and runs at room temperature. These attributes set up respectable “Faradaic efficiencies” [...]
Take a paper like sheet of the world’s thinnest material, graphene, and blast it with a laser or a camera flash to blemish it with countless cracks, pores, and other imperfections and create an easy-to-make, quick-charging lithium-ion battery with high power density. As a practical matter the graphene anode material can be charged or discharged [...]
Zhong Lin Wang, a Regents professor in the School of Materials Science and Engineering at the Georgia Institute of Technology leads a team that has developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. The technology eliminates the need to convert [...]

, Home Introduction Graphene Investing Defects in Graphene used to make a fast battery anode , ready for commercialization Tweet Batteries Graphene applications Graphene Oxide Technical Research Researchers from the Rensselaer Polytechnic Institute have developed a new graphene based anode that can be charged or discharged 10 times faster than conventional graphite anodes currently used in today’s lithium-ion batteries . To create the new anode material , the researchers took a sheet of graphene-oxide paper and then introduced defects using a laser or a camera flash on the . material The graphene paper , after being damaged , has expanded five-fold in thickness , which means that there were large voids between the graphene sheets . The lithium ions can use the cracks in the paper to
Martin Linck, Ph.D. a scientist at the Gas Technology Institute (GTI) reported to the 244th National Meeting & Exposition of the American Chemical Society (ACS) a new process for converting municipal waste, algae, corn stalks and similar material direct to gasoline, diesel and jet fuel. It’s a report not to be taken lightly, the GTI [...]
Dr. Norbert Mueller, an associate professor at Michigan State University’s (MSU) college of engineering, plans to have a new engine generating power through a 25-kilowatt battery out later this year. The new engine connected to a generator and buffered by a battery and likely some capacitor storage would be powerful enough to run a full [...]
Home Introduction Graphene Investing Nokia patents a graphene-based photo detector Tweet Nanoribbons Photonics Technical Research Nokia filed a new patent for a graphene-based photo detector . The new detector uses graphene as a photo-collecting layer , and also uses a graphene nanoribbon that acts as a field effect transistor to amplify the current and transfer it to the control electronics . Stacking several such detectors on top of each other with color filters can be done to detect . colors The big advantage of this graphene-based photo detector is graphene's transparency . The graphene sheet itself absorbs only 2.3 of the light and does it very evenly across the whole light spectrum and so should perform much better than CMOS in low light conditions . The graphene sensor will also be
Home Introduction Graphene Investing Graphene sponge can be used to absorb oil spills Tweet Graphene applications Technical Research Researchers developed a new sponge-like structure from graphene that has very good absorbance properties especially useful to remove petroleum products including kerosene , pump oil , fats , and organic solvents from seawater . The sponge absorbed up to 86 times its weight which is higher than all common . absorbents Using simple heating causes the absorbed hydrocarbons to be recovered with a 99 yield which means that you can reuse the sponge up to 10 . times The graphene sponge was fabricated by reducing graphene oxide and then applying a hydrothermal molding procedure in order to achieve a morphology with a high surface . area Source : NanoTechNow Aug 14,
