Power/Performance Bits: June 7


Tiny lasers on silicon A group of scientists from Hong Kong University of Science and Technology, the University of California, Santa Barbara, Sandia National Laboratories, and Harvard University were able to fabricate tiny lasers directly on silicon. To do this, they first had to resolve silicon crystal lattice defects to a point where the cavities were essentially equivalent to those gr... » read more

3D nanoshaping A team of researchers led by Purdue University report they’ve developed a method for creating large-area patterns of 3D nanoshapes from metal sheets. They believe this represents a potential manufacturing system to inexpensively mass produce innovations such as "plasmonic metamaterials" for advanced technologies, and could enable high-speed electronics, advanced sensors and so... » read more

Optical Metamaterial with a Refractive Index of Zero Most of the time we hear about the need for coherent light sources, such as those produced by lasers, but there may be equal promise looking in the other direction. Quantum processors promise to be many times faster and more powerful than today’s supercomputers, but to get to that point they will need fast and efficient multi-directiona... » read more

Scaling The Quantum Slopes Like any task, there are easy and hard ways to control atoms and molecules as quantum systems, which are driven by tailored radiation fields. More efficient methods for manipulating quantum systems could help scientists realize the next generation of technology by harnessing atoms and molecules to create small but incredibly powerful devices, such as molecular electr... » read more

Better Beer Rice University has devised a polymer material that could boost the properties of natural gas, beer and soda. By adding modified, single-atom-thick graphene nanoribbons (GNRs) to thermoplastic polyurethane (TPU), Rice’s polymer material could make it more practical for vehicles to run on compressed natural gas. The material is far more impermeable to pressurized gas and lighte... » read more
