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.

Bound for robotic glory

September 16, 2014 7:56 am | by Jennifer Chu, MIT News Office | Videos | Comments

The fastest land animal on Earth, the cheetah, is able to accelerate to 60 mph in just a few seconds. As it ramps up to top speed, a cheetah pumps its legs in tandem, bounding until it reaches a full gallop. Now, researchers have developed an algorithm for bounding that they’ve successfully implemented in a fully functional robotic cheetah.

Materials experts construct precise inter-nanotube junctions

September 15, 2014 12:05 pm | News | Comments

A new method for controllably constructing precise inter-nanotube junctions and structures in carbon nanotube (CNT) arrays, Northeastern Univ. researchers say, is facile and easily scal­able. It will allow them to tailor the phys­ical prop­er­ties of nan­otube net­works for use in appli­ca­tions ranging from elec­tronic devices to CNT-reinforced com­posite mate­rials found in every­thing from cars to sports equipment.

Ceramics don’t have to be brittle

September 11, 2014 5:00 pm | by Kimm Fesenmaier, Caltech | News | Comments

Imagine a balloon that could float without using any lighter-than-air gas. Instead, it could simply have all of its air sucked out while maintaining its filled shape. Such a material might be possible with a new method developed at the California Institute of Technology that allows engineers to produce a ceramic that contains about 99.9% air yet is strong enough to recover its original shape after being smashed by more than 50%.

Nanotechnology to provide cleaner diesel engines

September 9, 2014 8:32 am | by Bertel Henning Jensen, Technical Univ. of Denmark | News | Comments

When it comes to diesel engine catalysts, which are responsible for cleansing exhaust fumes, platinum has unfortunately proved to be the only viable option. This has resulted in material costs alone accounting for half of the price of a diesel catalyst. Researchers in Denmark say they have developed a new way to manufacture catalysts that may result in a 25% reduction in the use of platinum.

Soft robot squirms over fire, ice, and withstands crushing force

September 9, 2014 7:54 am | Videos | Comments

Engineers have created a shape-changing "soft" robot that can tread over a variety of adverse environmental conditions including snow, puddles of water, flames, and the crushing force of being run over by an automobile. The pneumatically powered, fully untethered robot was enabled by the careful selection of materials and composites, including silicone elastomer.

Doped graphene nanoribbons with potential

September 9, 2014 7:40 am | News | Comments

Typically a highly conductive material, graphene becomes a semiconductor when prepared as an ultra-narrow ribbon. Recent research has now developed a new method to selectively dope graphene molecules with nitrogen atoms. By seamlessly stringing together doped and undoped graphene pieces, ”heterojunctions” are formed in the nanoribbons, allowing electric current to flow in only one direction when voltage is applied.

A new concept in metallic alloy design called “high-entropy alloys” has yielded a multiple-element material that tests out as one of the toughest on record. But, unlike most materials, the toughness as well as the strength and ductility of this alloy, which contains five major elements, actually improves at cryogenic temperatures.

Simpler process to grow germanium nanowires could improve lithium-ion batteries

September 2, 2014 12:07 pm | by Andrew Careaga, Missouri Univ. of Science and Technology | News | Comments

As a semiconductor material, germanium is superior to silicon. But it is more expensive to process for widespread use in batteries, solar cells, transistors and other applications. Researchers in Missouri have now developed what they call “a simple, one-step method” to grow nanowires of germanium from an aqueous solution. Their process could make it more feasible to use germanium in lithium-ion batteries.

DARPA project aims to make nanoscale benefits life-sized

August 27, 2014 11:55 am | News | Comments

Many common materials exhibit different and potentially useful characteristics when fabricated at extremely small scales. But lack of knowledge of how to retain nanoscale properties in materials at larger scales and lack of assembly capabilities for items have prevented us from taking advantage of these nanoscale characteristics. DARPA has created the Atoms to Product (A2P) program to help overcome these challenges.
