Identifying chemicals from a distance could take a step forward with the introduction of a two-laser system being developed at the Department of Energy's Oak Ridge National Laboratory. In a paper published in the Journal of Physics D: Applied Physics, Ali Passian and colleagues present a technique that uses a quantum cascade laser to "pump," or strike, a target, and another laser to monitor the material's response as a result of temperature-induced changes. That information allows for the...

Nanocomposite electrodes being charged with electricity reveal performance advantages that could lead to longer-lasting, cheaper vehicle batteries A study that examines a new type of silicon-carbon nanocomposite electrode reveals details of how they function and how repeated use could wear them down. The study also provides clues to why this material performs better than silicon alone. With an electrical capacity five times higher than conventional lithium battery electrodes,...

A new, transformational battery that will offer the highest energy density and longest life cycle ( 70% cost reduction) of any lithium battery made today is being released by California Lithium Battery, Inc. California (PRWEB) March 15, 2012 California Lithium Battery Inc. (CalBattery) announced at last week´s Department of Energy´s ARPA-e Energy Innovation Summit in Washington, D.C. that they have entered into a Work for Others (WFO) agreement with Argonne National Laboratory...

Solar cells, light emitting diodes, displays and other electronic devices could get a bump in performance because of a discovery at the Department of Energy's Oak Ridge National Laboratory that establishes new boundaries for controlling band gaps. While complex transition metal oxides have for years held great promise for a variety of information and energy applications, the challenge has been to devise a method to reduce band gaps of those insulators without compromising the material's...

Microscopy Explores Nanowires' Weakest Link

Individual atoms can make or break electronic properties in one of the world's smallest known conductors–quantum nanowires. Microscopic analysis at the Department of Energy's Oak Ridge National Laboratory is delivering a rare glimpse into how the atomic structure of the conducting nanowires affects their electronic behavior. The ORNL team's microscopy confirmed that deliberately introduced defects, which are only the size of a single atom, could turn a conducting nanowire into an...

Creating and observing super-hot solid plasma could lead to a greater understanding of fusion processes. In two separate studies, the world´s most powerful X-ray laser has been used to build the first atomic X-ray laser pulse, as well as to superheat and control a clump of 2-million-degree matter. The atomic laser could be used to watch biological molecules at work, while the creation of hot dense matter could be used to understand the processes of nuclear fusion. Scientists...

Computer simulations revealing how methane and hydrogen pack into gas hydrates could enlighten alternative fuel production and carbon dioxide storage industries For some time, researchers have explored flammable ice for low-carbon or alternative fuel or as a place to store carbon dioxide. Now, a computer analysis of the ice and gas compound, known as a gas hydrate, reveals key details of its structure. The results show that hydrates can hold hydrogen at an optimal capacity of 5...
