The mission of Brookhaven's Advanced Materials Group is to conduct research on materials in extreme environments for advanced energy systems. As part of that mission, the group utilizes synchrotron characterization techniques such as diffraction, spectroscopy, and imaging and is developing sample chambers for the in situ study of materials at the National Synchrotron Light Source (NSLS). Shown here is group member Simerjeet Gill at beamline X14A at the NSLS.

The picture was taken from sample of an ancient bridge in Brazil dating from the 1860’s. Its structure is made in puddle iron, an historical structural material. It dates from the end of the 18th century and it was produced until the early 20th century. It represented a technological advance over cast iron. This material supplied the growing demand during the industrial revolution in England as it had a reduced production cost. On its manufacturing process, highly qualified workers called puddlers would try and remove the slag off the melting metal manually with the help of long shovels. This well paid job would lead them to an early death at an average age of 40 years old. Despite their effort, the resulting product still contained a considerable amount of slag, as we can see in the image. Many famous structures were built using this material such as the Eiffel tower and several bridges and railways across Europe.

An international team of researchers announced the observation of a dynamic Mott transition in a superconductor. The discovery experimentally connects the worlds of classical and quantum mechanics and illuminates the mysterious nature of the Mott transition. It also could shed light on non-equilibrium physics, which is poorly understood but governs most of what occurs in our world. The finding may also represent a step towards more efficient electronics based on the Mott transition. Read more »

As part of the ongoing National Cancer Initiative, researchers at Argonne National Laboratory have teamed up with oncologists at the University of Chicago to use infrared imaging of the head and neck to predict which patients have the highest risk for severe mucositis. The innovative, non-invasive imaging technique uses the body's own thermal signature as an indicator of the degree to which patients may suffer the toxic effects of cancer therapy.
Above: infrared images of a patient's head taken before (left) and after (center, right) a round of chemotherapy. The growth of the warmer, pinker areas around the mouth indicate the likely onset of mucositis. Read more »
A graphic shows how cement is turned into concrete
At the construction site, cement powder and sand or gravel “aggregate” are blended with water (or delivered pre-blended in a cement mixer truck). The resulting slurry is then poured into a mold and left undisturbed for several days or weeks, allowing a water-cement reaction to slowly harden the mix into concrete. This process doesn’t generate any more carbon dioxide. But it does lock in the aggregate, which adds strength and bulk to the concrete, along with any steel reinforcement bars.

To find, and possibly prevent, weak spots in materials under extreme stress, such as those at the heart of a nuclear reactor, scientists at PNNL are combining detailed macroscopic to microscopic images. This image shows a microscopic picture of a high-chromium, nickel-based alloy. Its surface was chemically etched to reveal faceted crystallographic planes at regions of localized microstructural damage. Through their research, scientists at PNNL are understanding how damage in metallic alloys evolves. This information may help identify failure mechanisms, improve reactor component reliability, and extend reactor life. Research was funded by the Nuclear Regulatory Commission and the U.S. Department of Energy.

A panel of five experts representing industry, academia, and government provided an overview of their own experiences and career journeys followed by questions from graduate and undergraduate students.
Graphic depicts the carbonation reaction, in which carbon dioxide is absorbed by concrete.
The carbonation reaction is nature’s way of reversing the cement-making process: As soon as calcium compounds in the concrete are exposed to carbon dioxide in the air, they spontaneously try to form calcium carbonate again. Although this process can put steel reinforcemeny bars at risk of corrosion, it does mean that old concrete structures will be-absorb as much as 40 percent of the carbon dioxide produced in building them.

A graphic depicts the rotating kiln in which cement is made, as well as the calcination reaction.
To make the Portland cement that’s used in most modern concrete, ground-up calcium-carbonate rock (usually limestone) is fed into a giant, rotating kiln along with clay. Hot air from a coal- or natural gas-fired furnace then raises the mix to the temperature of molten lava, and bakes out copious amounts of carbon dioxide. Left behind is calcium oxide (quicklime), which fuses with minerals in the clay and cools down into “clinker”: pale, grayish nodules that will be ground up to make cement powder. Between fossil-fuel combustion and the baked-out CO2, Portland cement production contributes about 8 percent of humanity’s total carbon dioxide emissions.

Laurence came to Sandia in 1989. Prior to that he worked for IBM for three years in Tucson after earning his BS degree in chemical engineering from New Mexico State University and MS in materials science and engineering from Stanford.
Laurence’s first job at Sandia was in the thin film and brazing department. After a one-year Entrepreneurial Leave of Absence in 1995, he returned to the same department working on cooperative research and development agreements that intersected organizations across the Labs. Since 2002, he has been with Sandia’s Government Relations organization, focusing primarily on tribal government relations and tribal energy development.

Magnesium — the lightest of all structural metals — has a lot going for it in the quest to make ever lighter cars and trucks that go farther on a tank of fuel or battery charge.
A new process developed at Pacific Northwest National Laboratory should make it more feasible for the auto industry to incorporate magnesium alloys into structural components. The method has the potential to reduce cost by eliminating the need for rare-earth elements, while simultaneously improving the material's structural properties. It's a new twist on extrusion, in which the metal is forced through a tool to create a certain shape, kind of like dough pushed through a pasta maker results in different shapes.

Anodized Aluminum oxide (AAO) is a porous material with self-organized, ordered array of pores arranged in honey comb like structure. The pore size can be varied from 5nm to few hundred nanometers in diameter. Each pore is tubular with an open end at top and a hard, solid barrier layer at the bottom. Anodized aluminum oxide can be used as a template for fabricating nanostructures using various techniques of deposition, etching etc. My work involves fabrication of nanotextured polymer surfaces using reactive ion etching technique with AAO as an etch mask.
This SEM image is an example of capillary action taking place at nanoscale. When AAO is spin coated with a solution of polystyrene (5wt% in toluene), the solution tends to wet the AAO structure along their pore walls. Once the solvent evaporates, it leaves tubular polystyrene nanowires inside the AAO pores. In this image, I spin coated the AAO with polystyrene and etched the barrier layer of AAO by floating it on phosphoric acid solution to open the pores at the bottom. After etching, I flipped the thin film such that the polystyrene coating is at the bottom of AAO and the post barrier layer etched pores are at the top. During SEM imaging, I focused on a fractured surface of AAO to reveal the polystyrene nanowires hiding underneath. The image has been modified with false color to add a sense of appeal and contrast. This image was taken using FEI Nova 430 scanning electron microscope at Nanoscale Research Facility(NRF) in University of Florida.

In this the ion beam images of the sample is shown. As it can be seen, there is a difference in contrast between different grains. The crystal contrast changes with the incidence angle of the ion beam as we have different plane orientation on the surface in this particular sample the crystal contrast varies from one grain to the other.Even twining boundaries can be seen in the image.
