Multicolored laser light is the key to cooling these atoms to nearly absolute zero UCLA physicists have shown that shining multicolored laser light on rubidium atoms causes them to lose energy and cool to nearly absolute zero. This result suggests … Continue reading →
Berkeley Lab’s nanotechnology enlivens Nanosys’ displays, enhancing the color and saving energy. Outside his career as a noted nanochemist, Lawrence Berkeley National Laboratory (Berkeley Lab) director Paul Alivisatos is an avid photographer. To show off his photos, his preferred device … Continue reading →
Princeton University researchers have built a rice grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or “maser,” is a demonstration of the fundamental interactions between light and moving electrons.
Two large collaborations of scientists working at the Large Hadron Collider in Switzerland made worldwide news in July 2012 when they announced independent observations of the elusive Higgs boson particle — a discovery hailed as one of the greatest scientific … Continue reading →
Berkeley Lab scientists develop a new nanotech tool to probe solar-energy conversion If nanoscience were television, we’d be in the 1950s. Although scientists can make and manipulate nanoscale objects with increasingly awesome control, they are limited to black-and-white imagery for … Continue reading →
Berkeley Lab scientists, major contributors to the ATLAS experiment at the Large Hadron Collider, explain what the excitement is about CERN, the European Organization for Nuclear Research headquartered in Geneva, Switzerland, will hold a seminar early in the morning on … Continue reading →
*Engineers at Brown University have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could … Continue reading →
Researchers at the UA-led Center for Integrated Access Networks, the largest optical research center in the U.S., are developing methods to improve transmission speed, efficiency and reliability of Internet content, including everything from cell phone calls or texts to emails … Continue reading →
