Smart Material Can Change Appearance and Revert
The materials, which are stretchable have potential applications in smart windows, display optics and encryption technology.
U.S. Finalizes Truck Fuel and Emission Standards
The final standards are expected to lower CO2 emissions by 1.1 billion metric tons and reduce oil consumption by two billion barrels over the lifetime of the vehicles sold under the program.
Silicon Anodes Could Boost Lithium-ion Battery Capacity
Capacity is limited because electrode materials such as graphite are able to stably adsorb a limited number of lithium ions.
"Liquid Fingerprinting" Technique to Be Commercialized
The W-INK concept exploits the chemical and optical properties of precisely nanostructured materials to distinguish liquids by their surface tension.
Oil and Gas Production Add to Ozone Woes, Study Says
Chemical vapors from oil and gas production add around 3 ppb a day of locally produced ozone in Colorado, and potentially more on high-ozone days.
Magnesium Process to Be Commercialized
MagSonic uses carbothermal reduction to heat magnesia with carbon to extreme temperatures, producing magnesium vapor and carbon monoxide.
Bio-Derived Battery Is Long Lasting and High Voltage
The battery is similar to many commercially available, high-energy lithium-ion batteries, but uses flavin from vitamin B2 as the cathode.
Lightweight Shape-Memory Alloy Could Have Aerospace Applications
Shape-memory alloys show behaviors such as superelasticity and shape recovery upon heating.
Nissan Unveils Solid-oxide Fuel Cell Vehicle
The e-Bio Fuel Cell prototype vehicle runs on 100% ethanol to charge a 24kWh battery that enables a cruising range of more than 600km.
Automaker Fabricates Vehicle Panels from Graphene
The benefits could have implications for cost, performance and fuel economy.
Marcellus Fracking Waste Below Federal Guidelines
Drilling a horizontal well in the Marcellus shale produces about 500 tons of rock fragments, known as cuttings.
Broadband Light Absorbers Could Boost Solar Cell Efficiency
The absorbers were shown to operate at 800 degrees Celsius and absorb light of wavelengths ranging from 300 to 1750 nanometers.
Study of Natural CO2 Reservoir Supports Viability of Carbon Capture
CO2 must remain buried for at least 10,000 years to avoid the impacts on climate.
Self-Healing Fabric Coating Could Be Used to Develop Protective Clothing
The polymer is self-healing in the presence of water, so laundering would repair micro and macro defects in the coating, making such garments rewearable and reusable.
Ethanol Is Fermented From Carbon Monoxide
The scientists found that Clostridium ljungdahlii feasts on and then ferments carbon monoxide.
Hydrogel Patch May Improve Colorectal Cancer Treatment
A clinician could remove a tumor and apply a patch to the inner surface of the colon.
Biofilm Protects Mortar Against Damaging Moisture
While water droplets' contact angle is typically 30 degrees or less on untreated mortar, it is three times as high for drops on the hybrid mortar.
ASTM Standard Developed for Large-size Concrete Pavers
The specification provides a baseline acceptance standard using any of three manufacturing processes: dry cast, wet cast and hydraulically pressed.
Suction-Based Adhesive Material Inspired by the Octopus
The rubbery material polydimethylsiloxane was utilized to create an array of microscale suckers that incorporate pores coated with a thermally responsive polymer to create sucker-like walls.
Improving Catalyst Efficiency for Clean Industries
Platinum is used as a catalyst to facilitate chemical reactions for many common products and processes, such as converting carbon monoxide to carbon dioxide in catalytic converters.
