Researchers develop new desalination technique

August 6, 2012 5:03 am | News | Comments

Lawrence Livermore National Laboratory researchers have developed a new capacitive desalination technique that could ultimately lower the cost and time of desalinating seawater. The technique, called flow-through electrode capacitive desalination, uses porous carbon materials with a hierarchical pore structure, which allows the saltwater to easily flow through the electrodes themselves.

Livermorium, Flerovium join the periodic table of elements

May 31, 2012 10:17 am | News | Comments

The International Union of Pure and Applied Chemistry officially approved new names for elements 114 and 116, the latest heavy elements to be added to the periodic table. Scientists of the Lawrence Livermore National Laboratory-Dubna collaboration proposed the names as Flerovium for element 114, with the symbol Fl, and Livermorium for element 116, with the symbol Lv, late last year.

New carbon dioxide-removing catalyst can take the heat

May 24, 2012 4:13 am | News | Comments

The current method of removing the greenhouse gas carbon dioxide from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that has developed an entirely new catalyst for separating out and capturing carbon dioxide, one that mimics a naturally occurring catalyst operating in our lungs.

LCLS graphite experiment poses new questions for researchers

May 21, 2012 10:25 am | News | Comments

In experiments at SLAC National Accelerator Laboratory, a powerful X-ray laser blasted solid carbon crystals into a liquid and plasma even faster than expected, raising new questions about how these intense beams interact with matter. The tests took place at the Linac Coherent Light Source, or LCLS, using a pioneering technique to simultaneously blast and probe samples of graphite, a pure form of carbon.

Graphite enters different states of matter in ultrafast experiment

May 15, 2012 8:37 am | News | Comments
