How many nanoparticles heat the tumour?

Scientists have been able to successfully demonstrate on mice that magnetic relaxometry is suited to be applied together with the heat treatment. It furnishes information about the whereabouts of the nanoparticles in the body - completely without contact to the patient.

The 'magic' of tin

The metal tin lacks the value and prestige of gold, silver, and platinum - but to nuclear physicists, tin is magic. Physicists recently reported studies on tin that add knowledge to a concept known as magic numbers while perhaps helping scientists to explain how heavy elements are made in exploding stars.

Timely technology sees tiny transitions

Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique by Rice University researchers will allow them to track single molecules without modifying them -- and it works over longer timescales.

Turning down the noise in graphene

Working with the unique nanoscience capabilities of the Molecular Foundry at the Lawrence Berkeley National Laboratory, a multi-institutional team of researchers has developed the first model of signal-to-noise-ratios for low frequency noises in graphene on silica. Their results show noise patterns that run just the opposite of noise patterns in other electronic materials.

Federal grant invests in nanostructured 'super' materials

Backed by a $1.2 million federal grant, the University of Wisconsin-Milwaukee (UWM) has launched a Center for Advanced Materials Manufacturing (CAMM) that will support the transfer of UWM research in bulk nanostructured materials to manufacturing industry in both Wisconsin and the nation.

Ultrafast gates for single atomic qubits

A team of physicists has achieved ultrafast 'switching' time in an operation central to quantum information processing, changing the state of a single trapped ion in less than 50 picoseconds with more than 99 percent reliability.
