Boston College chemists use nanowires to power photosynthesis Harnessing the power of the sun has inspired scientists and engineers to look for ways to turn sunlight into clean energy to heat houses, fuel factories and power devices. While a majority of this research focuses on energy production, some researchers are looking at the potential uses of these novel solar technologies in other areas. Boston College Assistant Professor of Chemistry Dunwei Wang's work with silicon nanowires...

A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind "pyroelectric nanogenerator" is the topic of a report in ACS' journal Nano Letters. Zhong Lin Wang and colleagues at Georgia Tech explain that more than 50 percent of the energy generated in the U.S. each year goes to waste, much of it as heat released to...

While the Statue of Liberty and old pennies may continue to turn green, printed electronics and media screens made of copper nanowires will always keep their original color. Duke University chemists created a new set of flexible, electrically conductive nanowires from thin strands of copper atoms mixed with nickel. The copper-nickel nanowires, in the form of a film, conduct electricity even under conditions that break down the transfer of electrons in plain silver and copper nanowires, a...

Nanoparticles Act As 'Artificial Atoms' To Form Complex Structures
2012-05-25 08:09:26

A new study by researchers at Lawrence Berkeley National Laboratory may resolve the question over whether or not nanoparticles act as "artificial atoms" when forming molecular-type building blocks that can assemble into complex structures. The findings could also have implications for synthesizing new biomimetic materials for use in next-generation energy devices, the researchers said. Led by Haimei Zheng, a staff scientist in Berkeley Lab's Materials Sciences Division, the researchers...

Sensors that work flawlessly in laboratory settings may stumble when it comes to performing in real-world conditions, according to researchers at the Department of Energy's Oak Ridge National Laboratory. These shortcomings are important as they relate to safeguarding the nation's food and water supplies, said Ali Passian, lead author of a Perspective paper published in ACS Nano. In their paper, titled "Critical Issues in Sensor Science to Aid Food and Water Safety," the researchers observe...

In the ongoing search for smaller, faster and more efficient computers, new research from the University of Gothenburg, Sweden suggests graphene and carbon nanotubes could be used to create these super small, super fast computers and smartphones. Both made of carbon, the nanotubes and graphene have specific and unique properties, making them ideal for computing. Graphene, for example, is made up of carbon layers which are only atom-thick. Nanotubes are comprised in a similar way, and...

Breathalyzer Reveals Signs Of Disease
2012-05-07 10:11:46

[ Watch the Video ] One exhale and new device could screen for everything from diabetes to lung cancer This invention could give new meaning to the term "bad breath!" It's the Single Breath Disease Diagnostics Breathalyzer, and when you blow into it, you get tested for a biomarker–a sign of disease. As amazing as that sounds, the process is actually very simple thanks to ceramics nanotechnology. All it takes is a single exhale. You blow into a small valve attached to a box that...

Scientists Say They've Found The Elusive Majorana Fermion
2012-04-15 04:48:19

After a search that has lasted roughly three-quarters of a century, researchers believe they have at long last discovered evidence of an elusive particle that could be its own anti-particle. The existence of the particle, which is known as the Majorana fermion, was first predicted some 75 years ago, according to BBC News Science Correspondent Jonathan Amos. Now, a team of Dutch scientists believe that they have created an electronic device small enough to test for the Majorana, and they...
