Evolution of a bimetallic nanocatalyst

Atomic scale snapshots of a bimetallic nanoparticle catalyst in action have provided insights that could help improve the industrial process by which fuels and chemicals are synthesized from natural gas coal or plant biomass A ... - Read More

Better tissue healing with disappearing hydrogels

When stem cells are used to regenerate bone tissue many wind up migrating away from the repair site which disrupts the healing process But a technique employed by a University of Rochester research team keeps ... - Read More

Quantum criticality observed in new class of materials

Quantum criticality the strange electronic state that may be intimately related to high temperature superconductivity is notoriously difficult to study But a new discovery of quantum critical points could allow physicists to develop a classification ... - Read More

60-year-old prediction of atomic behavior confirmed: New experimental path to superfast quantum computing

Researchers at Washington State University have used a super cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since The phenomenon takes ... - Read More

Electrical control of nuclear spin qubits: Important step towards quantum computers

Researchers of Karlsruhe Institute of Technology KIT and their French partners succeeded in making an important step towards quantum computers Using a spin cascade in single molecule magnet the scientists demonstrated how nuclear spins can ... - Read More

Opening a wide window on the nano-world of surface catalysis

Surface catalysts are notoriously difficult to study mechanistically but scientists at the University of South Carolina and Rice University have shown how to get real time reaction information from Ag nanocatalysts that have long frustrated ... - Read More

Scientists Capture Most Detailed Images Yet of Tiny Cellular Machines

are intimately linked together in a type of molecular symbiosis The structure yields clues about the relationship and the relative ages of RNA and proteins once thought to be much wider apart on an evolutionary ... - Read More
