I’ll take Creative Studying for 200, Alex: Jeopardy game prepares students for finals

The students in CBE 324, Transport Phenomena Laboratory, discovered a new method of study when they came to class on December 9 and 11: competing in the game show Jeopardy. Laboratory manager Eric Codner put the game together using a PowerPoint application, a classroom projector and two laptop computers. Each armed with a handheld response trigger, the students raced against their classmates to be the first to answer questions in categories such as “Rust never sleeps” and “So you want to be a milliliter.” Codner based the questions on technical topics covered throughout the semester, using the game as a tool to review the course materials. Students earned points for correct answers in the Jeopardy and Double Jeopardy rounds, then wagered points in the Final Jeopardy round to determine the winner of the prizes: a choice of movie passes or a copy of the lab safety video.

DOE FUNDS CATALYSIS SCIENCE INITIATIVE
With $1.6 million in funding over the next three years, Chemical and Biological Engineering Professors James Dumesic and Manos Mavrikakis will work with researchers from the University of Delaware and the University of Texas at Austin on a catalysis science initiative. The research project will refine the design of catalysts while at the same time develop new technologies that could lead to alternative fuels, the improvement of fuel cells, and a decrease in pollutants. The team is working to enhance selectivity by design through the integration of four critical components: theory and modeling; surface science; materials synthesis, characterization and scale-up; and catalyst and reactor dynamics and optimization. Technologies being developed by the research team include ways to make alternative fuels and chemicals from biomass, or plant material or vegetation that can be used as a fuel or energy source; new catalysts for fuel cells that are more efficient and less costly than current materials; and the reduction of nitrogen oxides, primarily in diesel engines.

TEAM SHEDS LIGHT ON SURFACE STRAIN, PLATINUM AND CO
The cover of the August issue of PCCP (Physical Chemistry Chemical Physics) features work by Chemical and Biological Engineering Professor Manos Mavrikakis and his team. The research shows surface strain to play a major role in determining the rate limiting step and catalytic activity of platinum for CO oxidation. The team writes that first-principle methods in combination with microkinetic modeling can provide valuable information and insights regarding the coupling between catalytic reaction thermochemistry and kinetics, and mechanical and thermal phenomena, all co-existing under realistic catalytic conditions.

Reactor made of gold tubes

Gold nanotubes in polycarbonate films for the investigation of catalytic reactions at gas-liquid phase boundaries

Fuel cells require hydrogen. Unfortunately, hydrogen produced by the usual process contains large amounts of carbon monoxide (CO), which has a negative effect on the function of the fuel cell and must be removed. Research has shown that gold nanoparticles on a support with a large surface area are good catalysts for the room-temperature oxidation of CO to CO2. But what is the gold doing in this process — and what is the role of the support? Researchers at the University of Wisconsin have developed a "membrane reactor", which allows them to examine the catalyst without its support.

What is the best way to study a catalyst made of nanoscopic particles in its "pure" state, without a support? The Team headed by James A. Dumesic had a clever idea. The researchers took a whisper-thin plastic membrane made of polycarbonate containing pores with a diameter of 220 nm. After the surface was specially prepared, gold was deposited onto the membrane. When the precious metal settled onto the walls of the tiny pores, pure gold nanotubes were formed. A subsequent etching process selectively removed the upper layer of the polycarbonate membrane, so that the gold nanotubes protruded from the surface. The researchers stretched this membrane between two chambers, one of which was used to admit gases, the other liquids. Indeed, just like gold nanoparticles, the gold nanotubes catalyzed the reaction of CO and O2 to form CO2.

Systematic examination of the reaction revealed the following: The catalytic activity is increased by the presence of water in the tubes, and is raised still further if the pH level is raised (the solution is made more alkaline). It is clear that hydroxyl groups (OH-), which come to the gold surface from basic materials or the dissociation of water molecules, facilitate the interaction between CO and O2, which seems to result in CO2 and peroxidic intermediates. This theory is supported by the fact that the reaction speeds for supported gold nanoparticles strongly depend on the type of material used for the support. Gold nanoparticles on oxide- containing supports in a damp atmosphere are most active, which fits the theory, since hydroxyl groups also occur under those conditions.

With hydrogen peroxide instead of oxygen as the oxidizing agent, the reaction runs better still, presumably because the bond between the two oxygen atoms in the former is easier to break.
