Electrospray solves longstanding problem in Langmuir-Blodgett assembly

25-Aug-2015

In the 1930s, Irving Langmuir and Katharine Blodgett discovered that by spreading molecules with volatile organic solvents on the surface of water, they could create a one-molecule-thick film and use it as an anti-reflective coating for glass. Later named Langmuir-Blodgett assembly, this ...

Graphene oxide's secret properties revealed at atomic level

A research team found that graphene oxide's inherent defects give rise to a surprising mechanical property

25-Aug-2015

Since its discovery, graphene has captured the attention of scientists and engineers for its many extraordinary properties. But graphene oxide largely has been viewed as graphene's inferior cousin. "Graphene is so perfect," said Northwestern Engineering's Jiaxing Huang. "And graphene oxide is ...

A new design for an easily fabricated, flexible and wearable white-light LED

25-Aug-2015

Researchers from National Chiao Tung University, Taiwan have created highly flexible, efficient white LEDs with potential use in wearable displays and non-flat surfaces, such as curved and flexible television screens. While the design itself is new, the LED was completely fabricated from ...

Physicist tests theories of dark energy by mimicking the vacuum of space

24-Aug-2015

Ever since dark energy was discovered in 1998, scientists have been proposing theories to explain it - one is that dark energy produces a force that can be measured only where space has a very low density, like the regions between galaxies. Paul Hamilton, a UCLA assistant professor of physics and ...

Laser-burned graphene gains metallic powers

24-Aug-2015

Rice University chemists who developed a unique form of graphene have found a way to embed metallic nanoparticles that turn the material into a useful catalyst for fuel cells and other applications. Laser-induced graphene, created by the Rice lab of chemist James Tour last year, is a flexible ...

Chemours Consolidates and Strengthens TiO2 Business

24-Aug-2015

The Chemours Company announced two decisions that are elements of the company's five-point transformation plan. The company will close its Edge Moor manufacturing site located outside Wilmington, Delaware, which produces titanium dioxide (TiO2) and will shut down a TiO2 line (line 3) at its ...

From fluids to flames, research on the space station is helping advance technology

21-Aug-2015

A study explored the finer points of fluid dynamics, something that is experienced across the planet, but cannot quite be studied as carefully on Earth. A phenomenon called Marangoni convection is one of the fundamental principles of liquid motion and is revealed much more clearly in ...

'Quantum dot' technology may help light the future

21-Aug-2015

Advances at Oregon State University in manufacturing technology for "quantum dots" may soon lead to a new generation of LED lighting that produces a more user-friendly white light, while using less toxic materials and low-cost manufacturing processes that take advantage of simple microwave ...

Engineers identify how to keep surfaces dry underwater

Research team is first to identify surface 'roughness' required to achieve amazing feat

20-Aug-2015

Imagine staying dry underwater for months. Now Northwestern University engineers have examined a wide variety of surfaces that can do just that - and they know why. The research team is the first to identify the ideal "roughness" needed in the texture of a surface to keep it dry for a long period ...

Mosquito-repelling chemicals identified in traditional sweetgrass

19-Aug-2015

Native North Americans have long adorned themselves and their homes with fragrant sweetgrass (Hierochloe odorata), a native plant used in traditional medicine, to repel biting insects, and mosquitoes in particular. Now, researchers report that they have identified the compounds in sweetgrass that ...
