Want to print your own cell phone microscope for pennies?

September 16, 2014 8:01 am | by Susan Bauer, PNNL | Videos | Comments

At one o'clock in the morning, layers of warm plastic are deposited on the platform of the 3-D printer that sits on scientist Rebecca Erikson's desk. A small plastic housing, designed to fit over the end of a cell phone, begins to take shape. Pulling it from the printer, Erikson quickly pops in a tiny glass bead and checks the magnification.

Scientists make cheap, fast self-assembling robots

August 7, 2014 3:51 pm | by Seth Borenstein, AP Science Writer | News | Comments

Borrowing from the ancient Japanese art of origami, children's toys and even a touch of the "Transformers" movies, scientists and engineers at Harvard University and the Massachusetts Institute of Technology have created self-assembling, paper robots. These complex machines transform themselves from little more than a sheet of paper and plastic into walking automatons.

Driving Back Defects

August 6, 2014 10:13 am | by Paul Livingstone | Articles | Comments

Traditional lithography is based on a simple principle: Oil and water don’t mix. The method, first developed by an actor in Bavaria in 1796, used a smooth piece of limestone on which an oil-based image was drawn and overlayed with gum arabic in water. During printing, the ink was attracted to the oil, and was repelled by the gum.

After hybrid success, Toyota gambles on fuel cell

July 17, 2014 8:55 am | by Yuri Kageyama, AP Business Writer | News | Comments

Long dismissed as too impractical and expensive for everyday cars, fuel cell technology is getting a push into the mainstream by Toyota, the world's top-selling automaker. Buoyed by its success with electric-gasoline hybrid vehicles, Toyota is betting that drivers will embrace hydrogen fuel cells, an even cleaner technology. The company’s fuel cell car will go on sale before April next year.

Diamond plates create nanostructures through pressure, not chemistry

June 27, 2014 3:09 pm | News | Comments

You wouldn’t think that mechanical force could process nanoparticles more subtly than the most advanced chemistry. But researchers at Sandia National Laboratories have created a newly patented and original method that uses simple pressure to produce finer and cleaner results in forming silver nanostructures than do chemical methods, which are not only inflexible in their results but leave harmful byproducts.

The inflatable concrete dome

June 11, 2014 3:51 pm | News | Comments

When concrete shells are constructed, they usually have to be supported by elaborate timber structures. This is one reason why such structures are now rarely built. In Austria, engineers have developed a new construction method that does not require any solid supporting structure at all. Instead, an air cushion is inflated below a concrete slab, bending the concrete and quickly forming a self-supporting shell.

Researchers in China develop cheaper method for making superlyophobic surfaces

June 11, 2014 11:41 am | News | Comments

Superlyophobic surfaces are simultaneously repellant for almost any liquid and exhibit high contact angles and low flow resist. But the demanding and usually expensive fabrication remains a bottleneck for further development. Researchers in Shenzhen, China, however, have now formulated a facile and inexpensive microfabrication method that uses polymers to help transfer the superlyophobic structures to curable materials.

June 10, 2014 3:12 pm | News | Comments

Engineers at Oregon State University have successfully shown that a continuous flow reactor can produce high-quality nanoparticles by using microwave-assisted heating. This is essentially the same force that heats up leftover food with such efficiency, but instead of warming up yesterday’s pizza, this concept may change the production of cell phones and televisions or improve solar energy systems.

R&D Scene: 3-D Printing Ushers In New Era of Manufacturing

June 9, 2014 1:42 pm | by Lindsay Hock, Managing Editor | Videos | Comments

The hunt for white aluminium

May 30, 2014 10:29 am | by Katrine Krogh-Jeppesen, DTU | News | Comments

Bang & Olufsen is working with scientists in Denmark to develop a method for creating white aluminium surfaces. This has been exceedingly difficult for manufacturers because the existing technology used to color aluminium cannot be used to produce the color white because the molecules used to create “white” are too big. Rather than use pigments, then, researchers have a way to make it become white during the process.

New engine design could reduce aircraft fuel consumption by 15%

May 27, 2014 12:20 pm | by Christian Johansson, Chalmers University of Technology | News | Comments

According to new research from Sweden, two aircraft engine concepts, a geared turbofan and an open rotor, can enable a significant reduction to aircraft fuel consumption. With an open rotor, the potential reduction is 15%. An open rotor engine generates most of the thrust from two counter-rotating propellers instead of a ducted fan. This enables a larger engine diameter and a higher propulsive efficiency.
