New metamaterial manipulates sound to improve acoustic imaging

18-Dec-2015 - Researchers from North Carolina State University and Duke University have developed a metamaterial made of paper and aluminum that can manipulate acoustic waves to more than double the resolution of acoustic imaging, focus acoustic waves, and control the angles at which sound passes through the ...

New nanomethod paves the way for new measuring technology and hypersensitive sensors

05-Nov-2009 - Researchers at Chalmers University of Technology in Sweden have developed a new measurement technology that makes use of optical resonances in nanoparticles. The method, which opens new possibilities in the field of catalytics, will be published in the journal Science for November and is already ...

NIST calculations may improve temperature measures for microfluidics

14-Sep-2009 - If you wanted to know if your child had a fever or be certain that the roast in the oven was thoroughly cooked, you would, of course, use a thermometer that you trusted to give accurate readings at any temperature within its range. However, it isn't that simple for researchers who need to measure ...

New experiment could reveal make-up of the universe

10-Aug-2009 - The detectors will become part of the Advanced Gamma Tracking Array (AGATA) experiment, currently based in Italy, which aims to create a 'fingerprint' of the inside of the atomic nucleus to understand the structure of all matter in the Universe, including human beings and the stars. The ...

Research measures movement of nanomaterials in simple model food chain

Photomicrograph of ciliate T. pyriformis during cell division with accumulated quantum dots appearing red

03-Jun-2008 - New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level ...

Squeezed crystals deliver more volts per jolt

04-Feb-2008 - A discovery by scientists at the Carnegie Institution has opened the door to a new generation of piezoelectric materials that can convert mechanical strain into electricity and vice versa, potentially cutting costs and boosting performance in myriad applications ranging from medical diagnostics ...

Rice scientists unveil 'nanoegg'

Asymmetric particles focus light in unique way

25-Jul-2006 - Contact: Jade BoydResearchers at Rice University's Laboratory for Nanophotonics (LANP) have unveiled the "nanoegg," the latest addition to their family ultrasmall, light-focusing particles. A cousin of the versatile nanoshell, nanoeggs are asymmetric specks of matter whose striking optical ...

Simple synthesis of three-dimensional microstructures by time-delayed electrodeposition

11-Mar-2003 - Increasingly smaller and more intricate microsystems technology is gaining ground. Complete systems for chemical analysis or medical diagnostics, among others, can now be reduced to the size of a thumbnail. However, production of the necessary three-dimensional microstructures by conventional ...
