Electricity Generating Nano-Wizards

May 18, 2015 — Quantum dots are an ideal nanolab to study the means to turning heat into electricity. Just as alchemists always dreamed of turning common metal into gold, their 19th century physicist counterparts ... read more

May 15, 2015 — Only recently has nanotechnology made it possible to reach the scale required to test the theoretical model known as the Tomonaga-Luttinger theory. Now, a team of researchers has succeeded in ... read more

Revealing Breast Cancer Using Nanoscale Polymers

May 14, 2015 — A biocompatible polymer selectively targets and lights up cancer tumors for a noninvasive imaging system, investigators report. Generating photoacoustic signals requires an ultrafast laser pulse to ... read more

May 13, 2015 — A new technique can measure the relative positions of tiny particles as they flow through a fluidic channel, potentially offering an easy way to monitor the assembly of nanoparticles, or to study how ... read more

May 15, 2015 — One of the barriers to using graphene at a commercial scale could be overcome using a new method. Graphene, a material stronger and stiffer than carbon fiber, has enormous commercial potential but ... read more

May 15, 2015 — Scientists have conducted a simulation that explains the collision between two clusters of galaxies. Clusters of galaxies are the biggest objects that exist in the universe. They are collections of ... read more

May 15, 2015 — A new porous material exhibits high electrical conductivity as a bulk material that is potentially tunable and has unusual temperature dependence, suggesting new fundamental ... read more

May 14, 2015 — Researchers have invented a technique called “CLAIRE” that extends the incredible resolution of electron microscopy to the non-invasive nanoscale imaging of soft matter, including biomolecules, ... read more

Predicting Magnetic Behavior in Copper Oxide Superconductors

May 14, 2015 — Enabled by high-performance computing, the magnetic couplings in model systems for copper-containing cuprate superconductors were accurately calculated for the first ... read more

May 14, 2015 — New technique makes nanomaterial self-assembly 1,000 times faster and could be used for industrial-scale solar panels and ... read more

'Swing-Dancing' Pairs of Electrons Discovered

May 13, 2015 — Scientists have discovered electrons that can 'swing dance.' This unique electronic behavior can potentially lead to new families of quantum ... read more

May 13, 2015 — Physicists have built a microscope that is able to see up to 1,000 individual fermionic atoms. The researchers devised a laser-based technique to trap and freeze fermions in place, and image the ... read more

May 13, 2015 — The recombination of electron shells in molecules, taking just a few dozen attoseconds (a billionth of a billionth of a second) can now be viewed 'live,' thanks to a new ... read more

May 12, 2015 — Scientists have developed a new composite photocathode for generating hydrogen using sunlight. The photocathode consists of a thin film of chalcopyrite coated with a newly developed thin film of ... read more

Detection of Spin of Atoms at Room Temperature Theoretically Demonstrated

May 12, 2015 — For the first time, a researcher has theoretically demonstrated that it is possible to detect a single nuclear spin at room temperature, which could pave the way for new approaches to medical ... read more

May 12, 2015 — Magnetic fields easily penetrate matter. Creating a space practically devoid of magnetic fields thus presents a great challenge. An international team of physicists has now developed a shielding that ... read more

May 12, 2015 — Topological insulators are "strange" materials, insulators on the inside and conductors on the surface. They also have properties that make them excellent candidates for the development of ... read more

May 11, 2015 — Rydberg atoms, atoms whose outermost electrons are highly excited but not ionized, might be just the thing for processing quantum information. These outsized atoms can be sustained for a long time in ... read more

First Theoretical Proof: Measurement of a Single Nuclear Spin in Biological Samples

May 11, 2015 — Physicists were able to show that the nuclear spins of single molecules can be detected with the help of magnetic particles at room temperature. The researchers describe a novel experimental setup ... read more

May 7, 2015 — Researchers have succeeded in creating a new 'whispering gallery' effect for electrons in a sheet of graphene -- making it possible to precisely control a region that reflects electrons ... read more
