Researchers in England have found a promising method for producing hydrogen from sunflower oil, a development that could lead to cleaner and more efficient hydrogen production for powering automobile fuel cells as well as homes, factories and offices. The development was described today at the 228th national meeting of the American Chemical Society, the world’s largest scientific society.
Fuel cells show much promise for supplying the energy needs of the future, and their demand is growing with increasing use of the technology. But one of their drawbacks, experts say, is that the hydrogen required to run them generally comes from the burning of fossil fuels, which generate pollutants such as carbon monoxide and greenhouse gases like carbon dioxide and methane.
"Producing hydrogen from sunflower oil could provide a more environmentally-friendly alternative by reducing these pollutants while offering an abundant, low-cost and renewable resource that reduces dependence on foreign oil," says the study’s lead researcher, Valerie Dupont, Ph.D., an energy engineer with the University of Leeds in England.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
