Nanotube Pencil Can Draw Sensors On Paper
2012-10-10 04:30:05

redOrbit Staff & Wire Reports - Your Universe Online Chemists at MIT have created a customized, carbon nanotube lead that can be used to draw freehand electronic circuits using a conventional, mechanical pencil. A typical pencil lead is fashioned out of graphite -- a form of carbon made up of layers of graphene -- and a clay binder. Whenever a person writes with a graphite pencil, a mixture of tiny graphene flakes and clay are deposited on the paper, leaving behind a mark. In the...

Mathematics Of Decomposition And Carbon Dioxide
2012-10-04 07:48:18

April Flowers for redOrbit.com - Your Universe Online The fall leaves look like confetti piling up in your back yard with brilliant reds, golds, and oranges. They can be thought of as natural stores of carbon, as well as a beautiful nuisance that you have to rake up each Autumn. Leaves soak up carbon dioxide from the atmosphere in the spring, converting the gas into organic carbon compounds. In the fall, the leaves fall from the trees and decompose in the soil as they are eaten by...

Wearable Sensor Helps Map Environment
2012-09-25 21:22:56

Lee Rannals for redOrbit.com — Your Universe Online MIT researchers have developed a prototype sensor array that can be worn on the chest to automatically map out an environment surrounding the wearer. The wearable sensor system can create a digital map of the environment that the person who is using it is moving in. During experiments, students wore the sensor system while wandering halls at MIT. The sensors wirelessly relayed data back to a laptop in a conference room, and...

Ultrasound May Lead To Needle-Free Vaccinations
2012-09-14 14:57:53

Lee Rannals for redOrbit.com — Your Universe Online MIT researchers are working on a technique that will allow needle-free vaccinations by using ultrasound waves. The team wrote in the Journal of Controlled Release that applying two separate beams of ultrasound waves can uniformly boost permeability across a region of skin more rapidly than using a single beam of ultrasound waves. “This could be used for topical drugs such as steroids – cortisol, for example –...

Web Applications Work Faster With MIT's Pyxis
2012-09-01 06:06:01

April Flowers for redOrbit.com - Your Universe Online Databases are the backbone of the Web. If you have every read stories on Yahoo!, shopped on Amazon, booked a flight on Kayak, posted on Facebook or Twitter, or downloaded a song from iTunes, you have used those databases. Most major websites maintain huge databases for everything from inventory and customer reviews, to seat availability on flights, to photos and comments. Almost any transaction on any major site, be it shopping, travel,...

Lee Rannals for redOrbit.com — Your Universe Online MIT scientists say a new two-dimensional material may be able to open up a plethora of future applications. Reporting in the journal Nano Letters published online this month, researchers say they have already succeeded in making a variety of electronic components out of a new material similar to the one-atom graphene, molybdenum disulfide (MoS2), Tomás Palacios, the Emmanuel E. Landsman Associate Professor of...

New process developed at MIT could enable better LED displays, solar cells and biosensors – and foster basic physics research. Films made of semiconductor nanocrystals – tiny crystals measuring just a few billionths of a meter across – are seen as a promising new material for a wide range of applications. Nanocrystals could be used in electronic or photonic circuits, detectors for biomolecules, or the glowing pixels on high-resolution display screens. They also hold...
