While developing a promising new method to improve the capacity and lifetime of sodium ion rechargeable batteries, scientists from Pacific Northwest National Laboratory and Wuhan University in China used transmission electron microscopy at EMSL to get a detailed look at how nanomaterials in the battery react to different temperatures. This science enables technology that could store massive amounts of energy from solar or wind farms, to make it available for the electrical grid when it is needed.

EMSL's new quiet wing

nobody@flickr.com (EMSL) — Wed, 02 Feb 2011 12:55:46 -0800

EMSL posted a photo:

EMSL’s newest facility is being built to reduce to a near-minimum the vibrations, acoustics, and electromagnetics that can interfere with the resolution of scientific instrumentation. The Quiet Wing, which will open in early 2012, will benefit a broad spectrum of research including geochemistry, microbiology, fuel cell research, and catalysis.

EMSL posted a photo:

Using computational chemistry models, scientists at Pacific Northwest National Laboratory and EMSL showed how aluminum oxide in common soils can adsorb uranium—information that could be applied in environmental remediation efforts to understand the migration of contaminants underground. The research team performed quantum mechanical calculations with the EMSL-developed NWChem running on EMSL's supercomputer Chinook.

EMSL posted a photo:

Using the recently upgraded EMSL variable temperature scanning tunneling microscope (VT STM), scientists at Pacific Northwest National Laboratory performed a high-resolution STM investigation of the initial stages of molecular oxygen adsorption on a reduced TiO2(110) surface at 50 K. This was the first study to use the VT STM (Omicron) after the advancement made possible by ARRA funding.

EMSL's Opus: An Instrumental Integration

nobody@flickr.com (EMSL) — Mon, 24 Jan 2011 12:28:52 -0800

EMSL posted a video:

Would your scientific research benefit from a full symphony of instruments? At EMSL, we offer our users from around the world the ability to integrate among our eight capabilities, as well as between theory and experiment. We are living what Aristotle meant when he said, "The whole is greater than the sum of its parts." To illustrate this, we've experimented with a new way of communicating the role of integration in EMSL: through music. "EMLS's Opus: An Instrumental Integration" embodies the idea that several different instruments can come together to form something more beautiful than the sum of the individual parts. In addition to the sounds of EMSL's scientific instruments, you'll hear the voices of our staff and users talking about innovation and integration in their native languages. Diversity and collaboration describes the tools, disciplines, and people you'll find here, all working to address big scientific challenges. It's the beauty of EMSL... come join us! www.emsl.pnl.gov

Atom Probe Sample Holder at EMSL

nobody@flickr.com (EMSL) — Mon, 15 Nov 2010 11:41:12 -0800

EMSL posted a photo:

The LEAP® 4000 XHR local electrode atom probe tomography instrument enabled the first-ever comprehensive and accurate 3-D chemical imaging studies of low electrical conductivity materials, such as ceramics, semiconductors and oxides.

The LEAP capability is assisting EMSL's efforts to further scientific advancements in interface analysis and microstructural characterization, providing a new tool for understanding the relationship between the nanoscale structure of materials and their macroscopic properties.

Separations

nobody@flickr.com (EMSL) — Fri, 10 Sep 2010 11:16:47 -0700

EMSL posted a photo:

At the Department of Energy's EMSL, scientists build new technologies to more effectively separate the desired materials from heterogeneous samples. As an example, Grant Johnson, Julia Laskin, and Michael Lysonski created a soft-landing instrument that allows scientists to remove the desired catalyst from a complex sample. This instrument is now available to other users through EMSL.

As part of the 2010 EMSL Science as Art Competition, Negar Monfared entered this image of a nanoporous membrane, used as a mold for making polysilazane nanoarrays. After curing, polysilazane solidifies and shrinks. By chemical etching of the alumina membrane, nanoarrays remain. Further pyrolysis makes SiC nanoarrays.
