DNA Double Helix Does Double Duty in Assembling Arrays of Nanoparticles

In a new twist on the use of DNA in nanoscale construction, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators put synthetic strands of the biological material to work in two ways: They used ropelike configurations of the DNA double helix to form a rigid geometrical framework, and added dangling pieces of single-stranded DNA to glue nanoparticles in place.

Supernova Hunting with Supercomputers

Using a "roadmap" of theoretical calculations and supercomputer simulations performed by Berkeley Lab's Daniel Kasen, astronomers observed a flash of light caused by a supernova slamming into a nearby star, allowing them to determine the stellar system from which a Type Ia supernova was born. This finding confirms one of two competing theories about Type Ia supernovae birth.

The Future of Energy Looks Bright at Berkeley Lab

The Solar Energy Research Center (SERC), renamed to Chu Hall, opened today at Berkeley Lab. It will house laboratories and offices devoted to photovoltaic and electro-chemical solar energy systems designed to improve on what plants do and make transportation fuels.

The three-story, nearly 40,000 square-foot, building cost $59 million will house approximately 100 researchers and was named after former Berkeley Lab Director Steven Chu, who went on to become U.S. Energy Secretary.

Spin and Parity Measurements of the Elusive Lambda(1405) Particle

New Magnetic Phase Confirms Theoretical Predictions Related to Unconventional Superconductivity

The emergence of a new magnetic phase with a square lattice before the onset of superconductivity is revealed in some iron arsenide compounds, confirming theoretical predictions of the effects of doping on magnetic interactions between the iron atoms and their relationship to high temperature superconductivity. Understanding the origin of thermodynamic phases is vital in developing a unified theory for the elusive microscopic mechanism underlying high-temperature superconductivity.

Intertwining of Superconductivity and Magnetism

Experiments on a copper-oxide superconductor reveal nearly static, spatially modulated magnetism. Because static magnetism and superconductivity do not like to coexist in the same material, the superconducting wave function is also likely modulated in space and phase-shifted to minimize overlap, consistent with recent theory. This insight will aid in writing a predictive theory for high-temperature superconductivity.

Highly Conductive Germanium Nanowires Made by a Simple, One-Step Process

For the first time, germanium nanowires have been deposited on indium tin oxide substrate by a simple, one-step process called electrodeposition. The nanowires produced by this method have outstanding electronic properties and can be used as high-capacity anode material for lithium-ion batteries; however, the nanowires were previously too expensive and difficult to produce. This process may resolve the cost issue.

Giant Magnetic Effects Induced in Hybrid Materials

For a magnetic thin film deposited onto a transition metal oxide film, the magnetic properties change dramatically as the oxide undergoes a structural phase transition.

Potential applications are envisioned in the fields of information storage and power transmission.

They found that the flux is the main driver of surface temperature change.
