New property in graphene for better solar panels
A new mechanism for ultra-efficient charge and energy flow in graphene, opening up opportunities for developing new types of light-harvesting devices.
Researchers develop graphene-enhanced biophotovoltaic technology
Existing photovoltaic technology is not fully capable of realizing the promise of sustainable solar energy. Commercial and emerging photovoltaic technologies require energy-intensive extracting and manufacturing processes and often require metals like tin that generate social conflict and environmental harm with their mining. Slave and child labor, along with rampant environmental destruction and pollution are widespread in the tin mining industry, which in some places is even controlled by militias to fund wars.
Making fuel cells for a fraction of the cost
Fuel cells have the potential to be a clean and efficient way to run cars, computers, and power stations, but the cost of producing them is limiting their use. That's because a key component of the most common fuel cells is a catalyst made from the precious metal platinum.
Building the safe genes toolkit
DARPA created the Safe Genes program to gain a fundamental understanding of how gene editing technologies function; devise means to safely, responsibly, and predictably harness them for beneficial ends; and address potential health and security concerns related to their accidental or intentional misuse.
New battery coating could improve smart phones and electric vehicles
High performing lithium-ion batteries are a key component of laptops, smart phones, and electric vehicles. Currently, the anodes, or negative charged side of lithium ion batteries, are generally made with graphite or other carbon-based materials.
New technology will cut plug-in hybrid fuel consumption by one third
Engineers have taken inspiration from biological evolution and the energy savings garnered by birds flying in formation to improve the efficiency of plug-in hybrid electric vehicles by more than 30 percent.
Self-healing, transparent, highly stretchable material
Scientists have developed a transparent, self-healing, highly stretchable conductive material that can be electrically activated to power artificial muscles and could be used to improve batteries, electronic devices, and robots.
From ancient fossils to future cars
Researchers have developed an inexpensive, energy-efficient way to create silicon-based anodes for lithium-ion batteries from the fossilized remains of single-celled algae called diatoms. The research could lead to the development of ultra-high capacity lithium-ion batteries for electric vehicles and portable electronics.
Graphene nanoflake-based films developed as thermal interface material
Heat dissipation in electronics and optoelectronics is a major obstacle to further technology development. It limits further miniaturisation, power, performance and reliability.
Study shows some 3D printed objects are toxic
Researchers have found parts produced by some commercial 3D printers are toxic to certain fish embryos. Their results have raised questions about how to dispose of parts and waste materials from 3D printers.
Bathing suit cleans the water as you swim
A material created engineers is the key component of a swimsuit that won an international design competition for its ability to clean water as a person swims.
Making batteries with portabello mushrooms
Can portabello mushrooms stop cell phone batteries from degrading over time?
Hydrogen fuel cell technology for maritime applications
The U.S. Department of Transportation's Maritime Administration has announced that it is providing $500,000 to support a feasibility study for the design, construction, and operation of a high-speed passenger ferry powered by hydrogen fuel cell technology and a hydrogen refueling station.
TransPower heavy-duty electric vehicle technologies
Transportation Power Inc has announced results of independent laboratory testing at the University of California, Riverside.
Glass coating improves battery performance
Lithium-sulfur batteries have been a hot topic in battery research because of their ability to produce up to 10 times more energy than conventional batteries.
New paper-like material could boost batteries
Researchers have developed a novel paper-like material for lithium-ion batteries. It has the potential to boost by several times the specific energy, or amount of energy that can be delivered per unit weight of the battery.
Self-powered intelligent keyboard
By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered non-mechanical intelligent keyboard could provide a stronger layer of security for computer users.
Cutting electric vehicle energy use 51 percent
Researchers have shown that a vehicle navigation tool they created can cut electric vehicle energy use up to 51 percent.
