Benchtop Spectrofluorometer

September 17, 2014 2:03 pm | Product Releases | Comments

The new FluoroMax Plus from Horiba Scientific expands on the capabilities of the FluoroMax series with the option of a second detector and two position grating turret, providing an extended range out to 1650 nm, and TCSPC performance down to 25 ps.  The higher sensitivity offered by FluoroMax Plus enables faster measurement of weaker and smaller samples.

New algorithms lets owners swap, recharge battery modules in electric cars

September 17, 2014 1:51 pm | News | Comments

Imagine being able to switch out the batteries in electric cars just like you switch out batteries in a photo camera or flashlight. Engineers in California are trying to accomplish just that, in partnership with a local San Diego engineering company. Rather than swapping out the whole battery, which is cumbersome and requires large, heavy equipment, engineers plan to swap out and recharge smaller units within the battery, known as modules.

Oxides discovered by chemists could advance memory devices

September 17, 2014 1:35 pm | News | Comments

Combining materials that exhibit magnetic and ferroelectric properties could be a boon for electronics designs, revolutionizing logic circuits and jumpstarting spintronics. This task has proven difficult until a recently developed inorganic synthesis technique, created by chemists at The City College of New York, produced a new complex oxide that demonstrate both properties.

Sampling Methods for Microanalysis

September 17, 2014 11:48 am | by Mary L. Stellmack, McCrone Associates Inc. | McCrone Associates, Inc. | Articles | Comments

In order to identify contaminants in industrial products, it’s sometimes necessary to send samples of the contaminated material to a laboratory for analysis. The choice of sampling method and the selection of a shipping container are critical to ensure that a representative sample is obtained, and no additional foreign material (FM) is added to the sample during transport to the laboratory.

Designing more successful synthetic molecules

September 17, 2014 11:08 am | by Bjorn Carey, Stanford News Service | News | Comments

Ever since Robert Hooke first described cells in 1665, scientists have been trying to figure out what goes on inside. One of the most exciting modern techniques involves injecting cells with synthetic genetic molecules that can passively report on the cell's behavior. A new computer model could not only improve the sensitivity and success of these synthetic molecules, but also make them easier to design in the first place.

Scientists twist radio beams to send data

September 17, 2014 10:55 am | by Robert Perkins, Univ. of Southern California | News | Comments

Building on previous research that twisted light to send data at unheard-of speeds, scientists at the Univ. of Southern California (USC) have developed a similar technique with radio waves, reaching high speeds without some of the hassles that can go with optical systems. The researchers reached data transmission rates of 32 Gbps across 2.5 m of free space in a basement laboratory at USC.

Scientists refine formula for nanotube types

September 17, 2014 9:52 am | by Mike Williams, Rice Univ. | Videos | Comments

Many a great idea springs from talks over a cup of coffee. But it’s rare and wonderful when a revelation comes from the cup itself. Rice Univ. theoretical physicist Boris Yakobson, acting upon sudden inspiration at a meeting last year, obtained a couple of spare coffee cups from a server and a pair of scissors and proceeded to lay out—science fair-style—an idea that could have far-reaching implications for the nanotechnology industry.

Toward optical chips

September 17, 2014 9:42 am | by Larry Hardesty, MIT News Office | News | Comments

Chips that use light, rather than electricity, to move data would consume much less power. Of the three chief components of optical circuits—light emitters, modulators and detectors—emitters are the toughest to build. One promising light source for optical chips is molybdenum disulfide (MoS2), which has excellent optical properties when deposited as a single, atom-thick layer.

For electronics beyond silicon, a new contender emerges

September 17, 2014 8:13 am | by Caroline Perry, Harvard Univ. | News | Comments

Silicon has few serious competitors as the material of choice in the electronics industry. Yet transistors can’t simply keep shrinking to meet the needs of powerful, compact devices; physical limitations like energy consumption and heat dissipation are too significant. Now, using a quantum material called a correlated oxide, researchers have achieved a reversible change in electrical resistance of eight orders of magnitude.

Nanoribbon film keeps glass ice-free

September 17, 2014 7:58 am | by Jade Boyd, Rice Univ. | News | Comments

Rice Univ. scientists who created a deicing film for radar domes have now refined the technology to work as a transparent coating for glass. The new work by Rice chemist James Tour and his colleagues could keep glass surfaces from windshields to skyscrapers free of ice and fog while retaining their transparency to radio frequencies (RF).

Novel capability enables first test of real turbine engine conditions

September 17, 2014 7:46 am | by Tona Kunz, Argonne National Laboratory | News | Comments

Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy-efficient turbine blades thanks to a partnership between Argonne National Laboratory, the German Aerospace Center and the universities of Central Florida and Cleveland State. The ability to operate turbine blades at higher temperatures improves efficiency and reduces energy costs.

How to hide like an octopus

September 17, 2014 7:33 am | by David L. Chandler, MIT News Office | News | Comments

Cephalopods are among nature’s most skillful camouflage artists, able to change both the color and texture of their skin within seconds to blend into their surroundings. Engineers have long struggled to duplicate this in synthetic materials. Now a team of researchers has come closer than ever to achieving that goal, creating a flexible material that can change its color or fluorescence and its texture at the same time.

First water-based nuclear battery can be used to generate electrical energy

September 16, 2014 6:51 pm | News | Comments

Betavoltaics, a battery technology that generates power from radiation, has been studied as an energy source since the 1950s. Now, for the first time using a water-based solution, researchers at the Univ. of Missouri have created a long-lasting and more efficient nuclear battery that could be used for many applications such as a reliable energy source in automobiles and also in complicated applications such as space flight.

Team is first to capture motion of single molecule in real time

September 16, 2014 6:23 pm | News | Comments

Chemists at the Univ. of California, Irvine, have scored a scientific first: capturing moving images of a single molecule as it vibrates, or “breathes,” and shifts from one quantum state to another. The groundbreaking achievement, led by Ara Apkarian, professor of chemistry, and Eric Potma, associate professor of chemistry, opens a window into the strange realm of quantum mechanics.
