Physicist Chad McCoy at Sandia National Laboratories’ Z machine loads sample coatings into holders. The coatings are made up of very thin layers of confectioners’ sugar from the grocers, burnt to a state called carbon black, interspersed between only slightly thicker layers of silica, which is the most common material on Earth, and baked. When Z fires, researchers will observe how well particular coatings protect objects stacked behind them.

Intense optical pulses of laser light can manipulate electron motion, or "spin" and switch the magnetization in metallic films, yet the mechanism that causes electrons' spins to reverse their orientation has remained a mystery. New results from the LCLS reveal the importance of the nanoscale structure of the sample itself in these optically excited switching processes. As the laser light hits the sample, iron spin currents are generated that transfer their angular momentum to gadolinium spins within nanoscale regions of the sample. The localized transfer of angular momentum leads to an increase in magnetic order and a reversal in magnetism in specific regions, even as the bulk of the sample becomes disordered.

Environmental pollution is one of the most critical problems in the world. Of all environmental problems, the conservation of water resources is of particular importance given that water is an essential good for life. For this reason, many research groups join forces to find new and more effective techniques for water treatment, some of which are based on the use of ozone and radiation. This image shows a mixed oxide of ruthenium with perovskite structure that has been used as a catalyst in ozonation and photolysis processes of different contaminated waters.

Panelists discuss and answer questions from attendees at the Career Development Tools and Strategies session.
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 »

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.

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.
