Membraneless Fuel Cell Is Tiny, Versatile - SpaceDaily  Left: The system designed by Paul Kenis, a professor of chemical and biomolecular engineering, uses a Y-shaped microfluidic channel in which two liquid streams containing fule and oxidant merge and flow between catalyst-covered electrodes without mixing.    In applications such as power sources for portable computers or battery chargers, multiple fuel cells will have to be integrated to attain sufficient power levels. "Since the membraneless fuel cell is based on a phenomenon that occurs only at the microscale, we can't just scale up to larger dimensions," Kenis said. "Instead, we need to scale out by creating arrays of many fuel cells connected in series and in parallel."
Theories Of High-Temperature Superconductivity Violate Pauli Principle - SpaceDaily  Scientists seeking to explain high-temperature superconductivity have been violating the Pauli exclusion principle, a team of researchers from the University of Illinois at Urbana-Champaign and Rutgers University report. Any theory that does not embrace the Pauli principle has a lot of explaining to do, they say. "It is standard practice in physics to separate high- and low-energy scales through a procedure known as renormalization," changing the statics of the excitations within doped Mott insulators, and resulting in a violation of the Pauli principle.  

Big Hopes For Tiny, New Hydrogen Storage Material - SpaceDaily  Left:  PNNL scientist Anna Gutowska adds a catalyst to ammonia borane to release hydrogen. Scientists at PNNL are exploring using ammonia boron as a hydrogen storage material. "The compound ammonia borane is known to release hydrogen at temperatures below 80 degrees Celsius, but the rate of release is extremely slow," said Autrey. "In the nanophase, the hydrogen comes off very fast - approximately 100 times faster compared to conventional bulk ammonia borane." Based on computational thermodynamic analysis, researchers believe the process may eventually be designed to be reversible. A patent is pending on this process for hydrogen storage.
