Special X-Ray Technique Allows Scientists to See 3-D Deformations

In a new study published last Friday in Science, researchers at Argonne used an X-ray scattering technique called Bragg coherent diffraction imaging to reconstruct in 3-D the size and shape of grain defects. These defects create imperfections in the lattice of atoms inside a grain that can give rise to interesting material properties and effects.

Neptune: Neutralizer-Free Plasma Propulsion

The most established plasma propulsion concepts are gridded-ion thrusters that accelerate and emit a larger number of positively charged particles than those that are negatively charged. To enable the spacecraft to remain charge-neutral, a "neutralizer" is used to inject electrons to exactly balance the positive ion charge in the exhaust beam. However, the neutralizer requires additional power from the spacecraft and increases the size and weight of the propulsion system. Researchers are investigating how the radio-frequency self-bias effect can be used to remove the neutralizer altogether, and they report their work in this week's Physics of Plasmas.

Cheaper Natural Gas-Powered Cars On The Horizon?

    An illustration of a prototype 6-liter adsorbed natural gas (ANG) fuel tank that relies on innovative advanced porous materials and Texas A&M's proven expertise in metal-organic frameworks (MOF) and porous-polymer networks (PPN) to deliver low-pressure, high-density natural gas storage in vehicles.

When it comes to American consumers' vehicular preferences, Texas A&M University chemist Hongcai Joe Zhou says the choice often boils down to simple economics more so than availability, environment or altruism.

And while passenger vehicles that run on natural gas may be an option for the financially well-off, Zhou says a more cost-efficient system will be necessary to drive a nationwide shift from petroleum to cleaner-burning fuels.

Zhou's goal is to solve the technical hurdles related to natural gas storage -- answers that bode well for sectors ranging from energy and economics to global relations and preservation.

"We should invest in this for security reasons so we don't have to rely on countries that may not be our allies for petroleum and for environmental reasons, since a large part of air pollution comes from the transportation sector," Zhou said. "Government policy can help. However, the ultimate determining factor is that it has to be commercially viable. If it's too expensive, few will use it."

Natural gas tanks for passenger vehicles currently are large and clunky, and no one wants to buy an ugly car, Zhou says. He says a key technical hurdle is making the natural gas, which is less dense than petroleum because it's in the gaseous state, fit in roughly the same space that a conventional petroleum gas tank occupies. With the help of a recent $3 million Department of Energy grant, Zhou and his team are collaborating with automobile giant General Motors (GM), Lawrence Berkeley National Laboratory (LBNL) and Research Triangle Institute (RTI) to figure out how to take such a fuel tank from concept to reality.

Creating the necessary infrastructure to store and pump natural gas into vehicles would be prohibitively costly, so Zhou believes the solution is to use the existing natural gas infrastructure that runs through the homes and garages of millions of Americans for household uses, such as heating, cooling and cooking. The problem is that natural gas from those lines comes out at such a low pressure that it needs to be compressed to get it to the pressure it needs to be stored at in the fuel tank, a costly process. The trick: build a fuel tank that can store low-pressure natural gas, which is precisely what Zhou is using his considerable expertise in inorganic chemistry to do.

Zhou and his Texas A&M research group are working to adapt porous material to store a larger amount of the gas in the fuel tank and then let it out when needed. The key is to find the right kind of adsorbent, a type of substance that attaches atoms, ions or molecules to its surface. Zhou specializes in porous polymer networks (PPN) and metal-organic frameworks (MOF), which are crystalline frameworks consisting of metal ions along with ions or molecules that bind to the metal ions called organic ligands. Pores inside the MOF can be used for gas storage.

"This is high-risk, high-reward research," Zhou said. "It's going to take some time to overcome some of the technical challenges."

Zhou earned his doctorate in chemistry from Texas A&M in 2000 under the guidance of legendary inorganic chemist Dr. F. Albert Cotton. He then spent two years as a postdoctoral fellow at Harvard University and was an associate professor at Miami University prior to joining the Texas A&M Department of Chemistry faculty in 2008. He has served since 2011 as chief scientific advisor for framergy™, a Texas-based startup company that oversees the commercialization of groundbreaking MOF innovations for industrial uses, ensuring that the broader benefits of Zhou's research are realized across the state, nation and world.
