NANOTECH

NANOTECH
electron beam

CAMBRIDGE, Mass. -- Since the 1960s, computer chips have been built using a process called photolithography. But in the past five years, chip features have gotten smaller than the wavelength of light, which has required...

New techniques for building microelectromechanical systems show promise. CAMBRIDGE, Mass. -- Microelectromechanical systems — or MEMS — were a $12 billion business in 2014. But that market is dominated by just a handful of devices,...

A new three-drug delivery system for cancer treatment, especially metastatic melanoma, the deadliest form of skin cancer, has been developed by researchers. The work has demonstrated that the system may have particular value with...

Einstein was wrong about at least one thing: There are, in fact, "spooky actions at a distance," as now proven by researchers at the National Institute of Standards and Technology (NIST). Einstein used that term...

If you add quantum dots – nanocrystals 10,000 times smaller than the width of a human hair – to a smartphone battery it will charge in 30 seconds, but the effect only lasts for...
Shrinking materials

Most materials swell when they warm, and shrink when they cool. But UConn physicist Jason Hancock has been investigating a substance that responds in reverse: it shrinks when it warms. Although thermal expansion, and the...
Wood-based Diesel

Scientists create a new international research consortium to develop a sustainable chemical infrastructure JOHANNES GUTENBERG UNIVERSITAET MAINZ Petroleum might well be replaced by wood soon when it comes to manufacturing chemical substances. Research has now made...

Emily S Finn, Yale University Each of us is unique, with our own strengths, weaknesses and idiosyncrasies. While this is a truism everyone grasps intuitively, it’s been difficult to determine if and how this individuality...

Have a cavity? Ask your dentist about filling it with a mixture of nanoparticles including silica and zirconia. These white fillings (known as nano-composite resins) resemble teeth better than their metal alternatives and are...

A simple process produces carpets of carbon nanotubes that act as radio antenna for light. The tubes are synthesized at the size of incoming waves, and fabricated with tiny rectifiers to convert solar energy...

When did time begin? Did our universe burst forth in explosive space/time creation. The Big Bang, until recently, was our best shot at explaining the observable cosmos. Still, even little kids ask, “if time...

I can see myself a decade from now, closer to seventy than I care to admit, telling incredulous ears, “It used to take a while for cell phones to charge, and they died the...
