Advanced light source sets microscopy record

Berkeley Lab researchers achieve highest resolution ever with X-ray microscopy

15-09-2014

A record-setting X-ray microscopy experiment may have ushered in a new era for nanoscale imaging. Working at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab), a collaboration of researchers used low energy or "soft" X-rays to image structures only five ...

Lighting the way to graphene-based devices

Berkeley Lab researchers use light to dope graphene boron nitride heterostructures

21-05-2014

Graphene continues to reign as the next potential superstar material for the electronics industry, a slimmer, stronger and much faster electron conductor than silicon. With no natural energy band-gap, however, graphene's superfast conductance can't be switched off, a serious drawback for ...

Quarks in the looking glass

07-02-2014

From matching wings on butterflies to the repeating six-point pattern of snowflakes, symmetries echo through nature, even down to the smallest building blocks of matter. Since the discovery of quarks, the building blocks of protons and neutrons, physicists have been exploiting those symmetries to ...

The role of goop: Research shows pollution doesn't change the rate of droplet formation

20-02-2013

When it comes to forming the droplets that make up clouds, a little oily and viscous organic material apparently doesn't matter that much. And that's good news for reducing the uncertainty of climate model predictions. Understanding cloud formation is essential for accurate climate modeling, and ...

Engineers show feasibility of superfast materials

'Organic topological insulators' for quantum computing

18-02-2013

University of Utah engineers demonstrated it is feasible to build the first organic materials that conduct electricity on their edges, but act as an insulator inside. These materials, called organic topological insulators, could shuttle information at the speed of light in quantum computers and ...

Ames Laboratory scientists crack long-standing chemistry mystery

24-08-2012

A team of researchers at the U.S. Department of Energy's (DOE's) Ames Laboratory has answered a key question concerning the widely-used Fenton reaction – important in wastewater treatment to destroy hazardous organic chemicals and decontaminate bacterial pathogens and in industrial chemical ...

Nanoparticles seen as artificial atoms

Berkeley Lab researchers observations of nanorod crystal growth points way to next-generation energy devices

30-05-2012

In the growth of crystals, do nanoparticles act as "artificial atoms" forming molecular-type building blocks that can assemble into complex structures? This is the contention of a major but controversial theory to explain nanocrystal growth. A study by researchers at the U.S. Department of Energy ...

ORNL microscopy inspires flexoelectric theory behind 'material on the brink'

17-04-2012

Electron microscopy, conducted as part of the Shared Research Equipment (ShaRE) User Program at the Department of Energy's Oak Ridge National Laboratory, has led to a new theory to explain intriguing properties in a material with potential applications in capacitors and actuators. A research team ...

Standoff sensing enters new realm with dual-laser technique

26-03-2012

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 ...

The first spectroscopic measurement of an anti-atom

Berkeley Lab scientists helped build and operate the ALPHA antimatter trap at CERN, which has now probed the internal structure of the antihydrogen atom for the first time

09-03-2012

The ALPHA collaboration at CERN in Geneva has scored another coup on the antimatter front by performing the first-ever spectroscopic measurements of the internal state of the antihydrogen atom. Ordinary hydrogen atoms are the most plentiful in the universe, and also the simplest – so simple, in ...
