Electric-field distributions on mesoporous Au films under 532nm wavelength excitation. The electric-field distribution is taken from 10 nm in depth in the films, in which moderate electric-field amplitude is clearly observed inside or at the perimeter of

Holes in gold enhance molecular sensing

May 20, 2015 10:27 am | by MANA | Comments

Non-metallic mesoporous structures have already demonstrated potential for applications in gas storage, separation, catalysis, ion-exchange, sensing, polymerization and drug delivery. Metal mesoporous films could have fascinating and useful optical properties, as they are effectively the inverse of nanoparticle arrays. Researchers have demonstrated a simple approach for producing metal films with regular tuneable mesopores.

Toward 'green' paper-thin, flexible electronics

May 20, 2015 10:15 am | by ACS | Comments

The rapid evolution of gadgets has brought us an impressive array of "smart" products from phones to tablets, and now watches and glasses. But they still haven't broken free from their rigid form. Now, scientists are reporting ia new step toward bendable electronics. They have developed the first light-emitting, transparent and flexible paper out of environmentally friendly materials via a simple, suction-filtration method.

Natural gas versus diesel

May 20, 2015 8:24 am | by American Chemical Society | Comments

Some major trucking companies are turning to natural gas to fuel their fleets, and to earn “green” credit among customers. But celebrating lower emissions could be premature. Researchers have found that converting heavy-duty trucks to run on natural gas could lead to negative climate impacts if steps are not taken to improve engine efficiency and reduce methane emissions from the fuel’s supply chain.

Printing 3-D graphene structures for tissue engineering

May 20, 2015 8:15 am | by Amanda Morris, Northwestern Univ. | Comments

Ever since single-layer graphene burst onto the science scene in 2004, the possibilities for the promising material have seemed nearly endless. With its high electrical conductivity, ability to store energy, and ultra-strong and lightweight structure, graphene has potential for many applications in electronics, energy, the environment and even medicine.

NASA advances CubeSat concept for planetary exploration

May 20, 2015 8:08 am | by NASA Goddard Space Flight Center | Comments

Although scientists are increasingly using pint-size satellites sometimes no larger than a loaf of bread to gather data from low-Earth orbit, they have yet to apply the less-expensive small-satellite technology to observe physical phenomena far from terra firma. Jaime Esper, a technologist at NASA's Goddard Space Flight Center in Greenbelt, Md., however, is advancing a CubeSat concept that would give scientists that capability.

Seashell strength inspires stress tests

May 20, 2015 7:43 am | by Mike Williams, Rice Univ. | Comments

Mollusks got it right. They have soft innards, but their complex exteriors are engineered to protect them in harsh conditions. Engineers at the Indian Institute of Science and Rice Univ. are beginning to understand why. By modeling the average mollusk’s mobile habitat, they are learning how shells stand up to extraordinary pressures at the bottom of the sea.

Taking control of light emission

May 20, 2015 7:31 am | by David L. Chandler, MIT News Office | Comments

Researchers have found a way to couple the properties of different 2-D materials to provide an exceptional degree of control over light waves. They say this has the potential to lead to new kinds of light detection, thermal management systems and high-resolution imaging devices.

To fight bee decline, Obama proposes more land to feed bees

May 19, 2015 2:04 pm | by Seth Borenstein, AP Science Writer, Associated Press | Comments

A new federal plan aims to reverse America's declining honeybee and monarch butterfly populations by making millions of acres of federal land more bee-friendly, spending millions of dollars more on research and considering the use of fewer pesticides. While putting different type of landscapes along highways, federal housing projects and elsewhere may not sound like much in terms of action.

GE Launches the Next Evolution of Wind Energy Making Renewables More Efficient, Economic: the Digital Wind Farm

May 19, 2015 11:49 am | by GE | Comments

GE has announced the launch of its Digital Wind Farm, a dynamic, connected and adaptable wind energy ecosystem that pairs world-class turbines with the digital infrastructure for the wind industry. The technology boosts a wind farm’s energy production by up to 20 percent and could help generate up to an estimated $50 billion of value for the wind industry.

Modern medicine relies on optical fibers to cauterize unhealthy veins in a minimally invasive way. Now, Fraunhofer researchers have developed a laser processing method that facilitates automated series manufacture of these fibers at a much finer quality than ever before. The scientists presented a fiber probe prototype manufactured using the new technique at the measurement fair SENSOR+TEST 2015 in Nuremberg.

A robotic arm that can bend, stretch and squeeze through cluttered environments has been created by a group of researchers from Italy. Inspired by the eight arms of an octopus, the device has been specifically designed for surgical operations to enable surgeons to easily access remote, confined regions of the body and, once there, manipulate soft organs without damaging them.

An international project to find the first direct evidence of the existence of gravitational waves, will be officially inaugurated on May 19, 2015. Researchers at Cardiff University will use a powerful supercomputer to comb through data from two gravitational wave detectors now being brought online and will search, with unprecedented accuracy, for the first ever direct evidence of the existence of gravitational waves later this year.

Electricity generation and distribution infrastructure in the Western United States must be “climate-proofed” to diminish the risk of future power shortages, according to research by two Arizona State University engineers. Expected increases in extreme heat and drought events will bring changes in precipitation, air and water temperatures, air density and humidity.

Just as alchemists always dreamed of turning common metal into gold, their 19th century physicist counterparts dreamed of efficiently turning heat into electricity, a field called thermoelectrics. Such scientists had long known that, in conducting materials, the flow of energy in the form of heat is accompanied by a flow of electrons.
