Transmission lines for nanofocusing of infrared light

A joint cooperation between three research groups at nanoGUNE reports an innovative method to focus infrared light with tapered transmission lines to nanometer-size dimensions. This device could trigger the development of novel chemical and biological sensing tools, including ultra-small infrared spectrometers and lab-on-a-chip integrated biosensors.

Search for advanced materials aided by discovery of hidden symmetries in nature

A new way of understanding the structure of proteins, polymers, minerals, and engineered materials will be published in the May 2011 issue of the journal Nature Materials. The discovery by two Penn State University researchers is a new type of symmetry in the structure of materials, which the researchers say greatly expands the possibilities for discovering or designing materials with desired properties. The research is expected to have broad relevance in many development efforts involving physical, chemical, biological, or engineering disciplines including, for example, the search for advanced ferroelectric ferromagnet materials for next-generation ultrasound devices and computers

Power cables light the future path of superconductivity

One hundred years ago this month, superconductivity was discovered in the lab of Dutch physicist Heike Kamerlingh Onnes. Since then many more materials have shown to be superconducting, providing new applications and creating a new realm of physics.

14 quantum bits: Physicists go beyond the limits of what is currently possible in quantum computation

(PhysOrg.com) -- Quantum physicists from the University of Innsbruck (Austria) have set another world record: They have achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With this experiment the scientists have not only come closer to the realization of a quantum computer but they also show surprising results for the quantum mechanical phenomenon of entanglement.

Expanding the degrees of surface freezing

(PhysOrg.com) -- As part of the quest to form perfectly smooth single-molecule layers of materials for advanced energy, electronic, and medical devices, researchers at the U.S. Department of Energy's Brookhaven National Laboratory have discovered that the molecules in thin films remain frozen at a temperature where the bulk material is molten.

NIST ‘noise thermometry’ system measures Boltzmann constant

(PhysOrg.com) -- Researchers at the National Institute of Standards and Technology (NIST) have for the first time used an apparatus that relies on the "noise" of jiggling electrons to make highly accurate measurements of the Boltzmann constant, an important value for many scientific calculations. The technique is simpler and more compact than other methods for measuring the constant and could advance international efforts to revamp the world’s scientific measurement system.

Thermoelectric materials: recycling energy

(PhysOrg.com) -- For some years now, NASA has been using what are called thermoelectric materials to power its space probes. The probes travel such great distances from our sun that solar panels are no longer an efficient source of power
