Berkeley Lab study reveals molecular structure of water at gold electrodes

28-10-2014

When a solid material is immersed in a liquid, the liquid immediately next to its surface differs from that of the bulk liquid at the molecular level. This interfacial layer is critical to our understanding of a diverse set of phenomena from biology to materials science. When the solid surface is ...

A quick look at electron-boson coupling

Berkeley Lab researchers use ultrafast spectroscopy on many body effects

10-10-2014

Imagine being able to tune the properties of a solid material just by flashing pulses of light on it, for example turning an insulator into a superconductor. That is just one potential payoff down-the-road from the physical phenomenon of electrons and atoms interacting with ultrashort pulses of ...

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 ...

Fundamental chemistry findings could help extend Moore's Law

17-07-2014

Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law. But there's one component of the chip-making process ...

A path toward more powerful tabletop accelerators

03-06-2014

Making a tabletop particle accelerator just got easier. A new study shows that certain requirements for the lasers used in an emerging type of small-area particle accelerator can be significantly relaxed. Researchers hope the finding could bring about a new era of accelerators that would need ...

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 ...

To bridge LEDs' green gap, scientists think small... really small

Nanostructures half a DNA strand-wide show promise for efficient LEDs

08-04-2014

Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes (LEDs), especially in the "green gap," a portion of the spectrum where LED efficiency plunges, simulations at the U.S. Department of Energy's National Energy Research Scientific Computing Center ...

Big step for next-generation fuel cells and electrolyzers

Researchers at Berkeley and Argonne National Labs discover highly promising new class of nanocatalyst

03-03-2014

A big step in the development of next-generation fuel cells and water-alkali electrolyzers has been achieved with the discovery of a new class of bimetallic nanocatalysts that are an order of magnitude higher in activity than the target set by the U.S. Department of Energy (DOE) for 2017. The new ...

Tracking catalytic reactions in microreactors

25-02-2014

A pathway to more effective and efficient synthesis of pharmaceutical drugs and other flow reactor chemical products has been opened by a study in which for the first time the catalytic reactivity inside a microreactor was mapped in high resolution from start-to-finish. The results not only ...

Hydrogen fuel from sunlight

02-09-2013

In the search for clean, green sustainable energy sources to meet human needs for generations to come, perhaps no technology matches the ultimate potential of artificial photosynthesis. Bionic leaves that could produce energy-dense fuels from nothing more than sunlight, water and ...
