A nano-gyroscope tracking device that fits on the head of a pin

Optical gyroscopes, also known as rotation sensors, are widely used as a navigational tool in vehicles from ships to airplanes, measuring the rotation rates of a vehicle on three axes to evaluate its exact position and orientation. Prof. Koby Scheuer of Tel Aviv University's School of Physical Engineering is now scaling down this crucial sensing technology for use in smartphones, medical equipment and more futuristic technologies.

Fuel cells in operation: A closer look

Traditional x-ray photoelectron spectroscopy (XPS) works only in a vacuum, while fuel cells need gases under pressure to function. Now a team of scientists from the University of Maryland, the U.S. Department of Energy's Sandia National Laboratories, and DOE's Lawrence Berkeley National Laboratory has used a new kind of XPS, called ambient-pressure XPS (APXPS), to examine every feature of a working solid oxide electrochemical cell.

For future chips, smaller must also be better

Two teams of researchers from China and France report success in making and testing tiny high-frequency capacitors made from a complex manmade mineral: barium strontium titanate (BST). By introducing an ultrathin (1.2 nanometer) titanium oxide seed layer, the researchers made thin BST films that exhibited excellent microwave properties up to 40 GHz.

Quantum computing research edges toward practicality

An important step - one that is essential to the ultimate construction of a quantum computer - was taken for the first time by physicists at UC Santa Barbara. The research involves the entanglement of three quantum bits of information, or qubits. Before now, entanglement research in the solid state has only been developed with two qubits.
