Researchers Improve Nanopore-based Technology For Detecting DNA Molecules
2013-11-18 08:34:01

Ecole Polytechnique Fédérale de Lausanne If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile. The latter resembles the model that EPFL researchers have used for creating a "DNA reader" that is able to detect the passage of individual DNA molecules through a tiny hole: a nanopore with integrated graphene transistor. The DNA molecules are diluted in a solution...

New Hologram Technology Created Using Tiny Nanoantennas
2013-11-15 10:27:00

Purdue University Researchers have created tiny holograms using a "metasurface" capable of the ultra-efficient control of light, representing a potential new technology for advanced sensors, high-resolution displays and information processing. The metasurface, thousands of V-shaped nanoantennas formed into an ultrathin gold foil, could make possible "planar photonics" devices and optical switches small enough to be integrated into computer chips for information processing, sensing and...

Researchers Grow Large Graphene Crystals That Have Exceptional Electrical Properties
2013-11-14 14:36:18

University of Texas at Austin When it comes to the growth of graphene — an ultrathin, ultrastrong, all-carbon material — it is survival of the fittest, according to researchers at The University of Texas at Austin. The team used surface oxygen to grow centimeter-size single graphene crystals on copper. The crystals were about 10,000 times as large as the largest crystals from only four years ago. Very large single crystals have exceptional electrical properties. "The game we play...

In-demand research report “Market Opportunities for Quantum Dots in Lighting and Displays” elaborated by NanoMarkets has been recently published by Market Publishers Ltd. London, UK (PRWEB) November 13, 2013 Quantum dots are semiconductor nanoparticles, with dimensions typically ranging from 2 to 10 nm. Their diminutiveness makes them highly flexible and versatile and therefore suitable for a lot of applications. Currently, the healthcare sector is the largest application for QD-based...

Researchers Develop Technique For Imaging Individual Carbon Nanotubes
2013-11-13 07:50:55

Lawrence Berkeley National Laboratory Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different “species,” each with its own structure and unique combination of electronic and optical properties. Characterizing the structure and properties of an individual carbon nanotube has involved a lot of guesswork – until now. Researchers with the U.S. Department of...

X-rays Reveal Unexpected Property Of Widely Used Nanoparticles
2013-11-12 15:02:07

European Synchrotron Radiation Facility A new chapter has been opened in our understanding of the chemical activity of nanoparticles says a team of international scientists. Using the X-ray beams of the European Synchrotron ESRF they showed that the electrons absorbed and released by cerium dioxide nanoparticles during chemical reactions behave in a completely different way than previously thought: the electrons are not bound to individual atoms but, like a cloud, distribute themselves...

Quest For ‘Invisibility Cloak’ Remains Elusive, It So Appears
2013-11-12 07:43:18

redOrbit Staff & Wire Reports - Your Universe Online Limitations in current cloaking technology allow objects to be temporarily concealed at only narrow wavelengths of light or microwaves, while many newer designs actually make things more visible, experts at the University of Texas acknowledged on Monday. Current cloaking devices, which are made of a variety of materials such as planes of glass, work by bending light around objects to make them temporarily invisible. Scientists...

Wireless Device Turns 'Lost' Energy Into Electric Power
2013-11-07 14:28:49

Duke University Metamaterial cells designed by Duke engineers provide electric power as efficiently as solar panels Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other...

Nanoparticles filled with chemotherapeutic drugs can kill drug-resistant breast cancer cells, according to a study published in the scientific journal Biomaterials. Nanoparticles are just as small, or even smaller, than many blood proteins. They can therefore pass through the walls of healthy and sick cells, which make them interesting carriers of drugs against cancer and other diseases. In the present study, researchers from Karolinska Institutet have shown that nanoparticles made from...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
