ASU researchers demonstrate the world's first white lasers
Tempe AZ (SPX) Jul 30, 2015
While lasers were invented in 1960 and are commonly used in many applications, one characteristic of the technology has proven unattainable. No one has been able to create a laser that beams white light. Researchers at Arizona State University have solved the puzzle. They have proven that semiconductor lasers are capable of emitting over the full visible color spectrum, which is necessary to produce a white laser. The researchers have created a novel nanosheet - a thin layer of semiconductor that ... read more

Short wavelength plasmons observed in nanotubes The term "plasmons" might sound like something from the soon-to-be-released new Star Wars movie, but the effects of plasmons have been known about for centuries. Plasmons are collective oscillations ... more		Nanotechnology research leads to super-elastic conducting fibers An international research team based at The University of Texas at Dallas has made electrically conducting fibers that can be reversibly stretched to over 14 times their initial length and whose ele ... more		Breakthrough in knowledge of how nanoparticles grow A team of researchers from the University of Leicester and France's G2ELab-CNRS in Grenoble have for the first time observed the growth of free nanoparticles in helium gas in a process similar to th ... more
				On the way to breaking the terahertz barrier for graphene nanoelectronics A team of scientists at the Max Planck Institute for Polymer Research (MPI-P) discovered that electrical conduction in graphene on the picosecond timescale - a picosecond being one thousandth of one ... more		A most singular nano-imaging technique Just as proteins are one of the basic building blocks of biology, nanoparticles can serve as the basic building blocks for next generation materials. In keeping with this parallel between biology an ... more

In the Bronze Age, the copper-tin alloy was melted and cast into weapons in ceramic molds. Today, injection and extrusion molding shape hot liquids ... more
				Nanoscale light-emitting device has big profile University of Wisconsin-Madison engineers have created a nanoscale device that can emit light as powerfully as an object 10,000 times its size. It's an advance that could have huge implications for ... more		Nanowires highly 'anelastic' Researchers from Brown University and North Carolina State University have found that nanowires made of zinc oxide are highly anelastic, meaning they return to shape slowly after being bent, rather ... more

Superslippery islands (but then they get stuck) (Nano)islands that slide freely on a sea of copper, but when they become too large (and too dense) they end up getting stuck: that nicely sums up the system investigated in a study just published in ... more		Ultra-thin, all-inorganic molecular nanowires successfully compounded Nanowires are wired-shaped materials with diameters that are tens of nanometers or less. There are many types of nanowires, including semiconducting composite nanowires, metal oxide composite nanowi ... more		New Structures Could Keep Astronauts Fit During Long Missions Aerospace modules completed for Artemis lunar crew mission MIT researchers propose a new model for legible, modular software		New nanogenerator harvests power from rolling tires A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car's rolling tire friction. An innovative method of reu ... more
Soft core, hard shell -- the latest in nanotechnology Nanoparticles are the smallest particles capable of reaching virtually all parts of the body.
