Scientists Control Molecules to Measure Quantum Effects of Molecular Collisions

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.

Twin-Peak Signal Accompanies Localisation in Wave's Velocity Distribution

Experiments could search for a 'twin peak' to gain insight into the peculiar phenomenon of wave localisation, CQT researchers and their collaborators have predicted.

Multiphase Shock Tube Generates Planar Shock Wave to Predict Particle Dispersal in Explosions

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.

Cosmic Ray Muons May Help Monitor Carbon Storage

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.

Planck Discovers Bridge of Hot Gas Connecting Galaxy Clusters

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.

QMC Granted US Patent for Synthesis of Inorganic Tetrapod Quantum Dots

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.

Quantum Researchers Open Possibility of Submolecular Control of Bond-Selective Chemistry in Single Functionalized Molecule

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”.

Internet Growth Linked to Emergence of Universe’s Four-Dimensional Spacetime from Quantum Vacuum

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.

Researchers Discover Hollow, Coated Versions of Quantum Dots

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.

Comparing Types of Supernovae May Help Define Nature of Dark Energy

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.

Multi-Object Double Spectrograph Reveals Likely Origins of Bright Supernovae

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.

Study Reveals Preferred Direction of Time's Quantum Arrow

Time marches relentlessly forward for you and me; watch a movie in reverse, and you'll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse – a concept known as time reversal symmetry.

World’s First Room-Temperature Electron Spin Amplifier

A fundamental cornerstone for spintronics that has been missing up until now has been constructed by a team of physicists at Linköping University in Sweden. It's the world's first spin amplifier that can be used at room temperature.
