Stanford University scientists have developed a "smart" lithium-ion battery that gives ample warning before it overheats and bursts into flames.
The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes.
"Our goal is to create an early-warning system that saves lives and property," said Yi Cui, an associate professor of materials science and engineering. "The system can detect problems that occur during the normal operation of a battery, but it does not apply to batteries damaged in a collision or other accident.
You may have heard about the hazards posed by pranksters who shine laser pointers at airplanes during takeoff or landing. One way to keep those beams of concentrated light from blinding pilots is to incorporate a special dye in the cockpit windows, one that blocks the wavelengths of laser light while letting other wavelengths through.
Optical dyes can be used to control color and light in applications ranging from laser welding to production of sunglasses and plasma TVs. The dyes used for this purpose are often expensive; others are cheap but apt to decompose when exposed to heat.
2-D alternatives to graphene may enable exciting advances in electronics, photonics, sensors and other applications.
Graphene, a form of carbon in which a single layer of atoms forms a two-dimensional, honeycomb crystal lattice, conducts electricity and heat efficiently and interacts with light in unusual ways. These properties have led to worldwide efforts in exploring its use in electronics, photonics and many other applications.
Rapid advances in graphene research during the last decade have suggested tantalizing possibilities for other two-dimensional materials, each of which might have distinct and useful properties.
Nanomanufacturing Goals for the National Nanotechnology Initiative: Breaking Down the NNI Strategic Plan 2014Highlights
As we review the various reports that have been made available to the public over the past few years regarding the federal investment in the National Nanotechnology Initiative (NNI), we continue to observe key language that supports the nanomanufacturing community broadly. An example is the Presidents Council of Advisors on Science and Technology (PCAST), which in their 2012 Assessment of the NNI cited the need for increased investment for nanomanufacturing and commercialization related activities. More recently, the 2014 NNI Strategic Plan provides a roadmap for key steps to support and foster these activities.
