First measurement of entangled states in nitrogen
|
|
When atoms form molecules, they share their outer electrons and this creates a negatively charged cloud. Here, electrons buzz around between the two positively charged nuclei, making it impossible to tell which nucleus they belong to. They are delocalized. But is this also true for the electrons located closer to the nucleus?

Research puts new wrinkle in study of materials folding under pressure
|
|
Scientists at the University of Chicago and the University of Santiago in Chile have explained, for the first time, the physics that governs how thin materials at scales millions of times different in thickness make the transition from wrinkles into folds under compression.

MIT Creates New Material For Fuel Cells, Increases Power Output By 50 Percent
|
|
MIT engineers have improved the power output of one type of fuel cell by more than 50 percent through technology that could help these environmentally friendly energy storage devices find a much broader market, particularly in portable electronics.

Nanotechnology In Reverse Uses Red Blood Cell To Calibrate Atomic Force Microscope
|
|
Nanotechnology researchers have shown that they can use a red blood cell to calibrate a sensitive instrument, an atomic force microscope. An atomic force microscope uses a tiny lever that runs over the surface of an object. Small deflections of the tip are read and translated to produce an image of the object's surface. However, accurate calibration of the springiness of the tip is difficult.

Physicists Demonstrate How Information Can Escape From Black Holes
|
|
Physicists have provided a mechanism by which information can be recovered from black holes -- and the first plausible mechanism for how information might escape from black holes, those regions of space where gravity is so strong that, according to Einstein's theory of general relativity, not even light can escape. The team's findings pave the way toward ending a decades-long debate sparked by renowned physicist Steven Hawking.

Nanostructures Will Raise Thin-Film Solar Cell Efficiency
|
|
Thanks to nanostructures that scatter and channel light, electrical engineers are working toward thin-film "single junction" solar cells with the potential for nearly 45 percent sunlight-to-electricity conversion efficiencies. This new effort aims to break the theoretical limit of 31 percent efficiency for conventional single junction cells.

Can One 'Pin Down' Electrons?
|
|
Experiments by physicists end a long-lasting dispute with an answer that apparently satisfies everyone. When atoms form molecules, they share their outer electrons and this creates a negatively charged cloud. Here, electrons buzz around between the two positively charged nuclei, making it impossible to tell which nucleus they belong to. They are delocalized. But is this also true for the electrons located closer to the nucleus?

Lasers Used To Align Molecules: Technique Could Revolutionize Human Protein Imaging
|
|
Protein crystallographers have only scratched the surface of the human proteins important for drug interactions because of difficulties crystallizing the molecules for synchrotron x-ray diffraction. Scientists have devised a way to eliminate the need for crystallization by using lasers to align large groups of molecules.
