Among the most important techniques developed in atomic physics over the past few years are methods that enable the storage and cooling of atoms and ions at temperatures just above absolute zero. Scientists from Bangalore and Mainz have now demonstrated in an experiment that captured ions can also be cooled through contact with cold atoms and may thus be stored in so-called ion traps in a stable condition for longer periods of time. This finding runs counter to predictions that ions would actually be heated through collisions with atoms.
Neutron scattering is a specialized tool that allows scientists to do breakthrough research into the nature of advanced materials.
Collisions between protons and lead ions at the Large Hadron Collider (LHC) have produced surprising behavior in some of the particles created by the collisions. The new observation suggests the collisions may have produced a new type of matter known as color-glass condensate.
Quantum computers are devices — still largely theoretical — that could perform certain types of computations much faster than classical computers; one way they might do that is by exploiting “spin,” a property of tiny particles of matter. A “spin chain,” in turn, is a standard model that physicists use to describe systems of quantum particles, including some that could be the basis for quantum computers.
For the first time, scientists have succeeded in controlling molecules so precisely that the quantum effects of a collision between molecules can be measured. The results will be published in Science on November 23rd. The ar [bw] ticle also provides a theoretical model of the interaction between the OH (hydroxyl) and NO (nitrogen monoxide) molecules used. Molecule collisions were previously thought to be too complex to model.
Experiments could search for a 'twin peak' to gain insight into the peculiar phenomenon of wave localisation, CQT researchers and their collaborators have predicted.
Sandia’s one-of-a-kind multiphase shock tube began with a hallway conversation that led to what engineer Justin Wagner describes as the only shock tube in the world that can look at how shock waves interact with dense particle fields.
Geoscientists, particle physicists and engineers will work together to examine the potential of using muons -sub-atomic particles from cosmic rays- which cascade from the upper atmosphere and go on to penetrate rock several kilometres underground. The detection of cosmic ray muons can be used to map the density profile of the material above the detectors and hence measure on-going levels of CO2 in any potential carbon store.
ESA's Planck space telescope has made the first conclusive detection of a bridge of hot gas connecting a pair of galaxy clusters across 10 million light-years of intergalactic space.
Quantum Materials Corporation, Inc. proudly announces the USPTO patent grant of a fundamental disruptive technology for synthesis of Group II-VI inorganic tetrapod quantum dots. The patent, "Synthesis of Uniform Nanoparticle Shapes with High Selectivity" and invented by Professor Michael S. Wong's group at William Marsh Rice University, Houston, TX, for the first time gives precise control of both QD shape and dimension during synthesis and is adaptable to quantum dots production of industrial scale quantities.
Recently, Dr. Ying Jiang, from International Center for Quantum Materials of Peking University, and his co-workers open up the possibility of submolecular control of the bond-selective chemistry in a single functionalized molecule. This work is published in Nature Chemistry [Nature Chem. DOI: 10.1038/NCHEM.1488 (2012)], and the referee thinks highly of the work as an “experimental tour de force”.
The structure of the universe and the laws that govern its growth may be more similar than previously thought to the structure and growth of the human brain and other complex networks, such as the Internet or a social network of trust relationships between people, according to a new paper published in the science journal Nature’s Scientific Reports.
Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new "lava dot" particles were discovered accidentally when researchers stumbled upon a way of using molten droplets of metal salt to make hollow, coated versions of a nanotech staple called quantum dots.
Supercomputer simulations have revealed that a type of oddly dim, exploding star is probably a class of duds—one that could nonetheless throw new light on the mysterious nature of dark energy.
A study using a unique new instrument on the world's largest optical telescope has revealed the likely origins of especially bright supernovae that astronomers use as easy-to-spot "mile markers" to measure the expansion and acceleration of the universe.
