Self-assembling nanorods: Berkeley Lab researchers obtain 1-, 2- and 3-D nanorod arrays and networks

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab researchers have developed a relatively fast, easy and inexpensive technique for inducing nanorods to self-assemble into aligned and ordered macroscopic structures. This technique should enable more effective use of nanorods in solar cells, magnetic storage devices and sensors, and boost the electrical and mechanical properties of nanorod-polymer composites.

Scientists help define structure of exoplanets

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving and testing the equation of state of matter in exoplanets and figured out the mass-radius and mass-pressure relations for materials relevant to planetary interiors.

Bright lights of purity

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab researchers have discovered why a promising technique for making quantum dots and nanorods has so far been a disappointment. Better still, they've also discovered how to correct the problem.

Berkeley Lab researchers discover critical rotational motion in cells

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab researchers have discovered a rotational motion that plays a critical role in the ability of breast cells to form the spherical structures in the mammary gland known as acini. This rotation, called "CAMo," for coherent angular motion, is necessary for the cells to form spheres. Otherwise, cells undergo random motion, leading to loss of structure and malignancy.

Scientists create first atomic X-ray laser

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Scientists have created the shortest, purest X-ray laser pulses ever achieved, fulfilling a 45-year-old prediction and opening the door to a new range of scientific discovery. The researchers aimed SLAC's Linac Coherent Light Source at a capsule of neon gas, setting off an avalanche of X-ray emissions to create the world's first "atomic X-ray laser."

World's most powerful X-ray laser creates 2-million-degree matter

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Researchers working at the US Department of Energy's SLAC National Accelerator Laboratory have used the world's most powerful X-ray laser to create and probe a 2-million-degree piece of matter in a controlled way for the first time. This feat takes scientists a significant step forward in understanding the most extreme matter found in the hearts of stars and giant planets, and could help experiments aimed at recreating the nuclear fusion process that powers the sun.

Power generation is blowing in the wind

DOE/Lawrence Livermore National Laboratory
Peer-Reviewed Publication

By looking at the stability of the atmosphere, wind farm operators could gain greater insight into the amount of power generated at any given time. Power generated by a wind turbine largely depends on the wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes (such as turbulence) to the wind profile, a turbine will produce different amounts of power.
