Surface physics: Leaving the islands
In a recent study involving researchers from Ludwig-Maximilians-Universitaet in Munich, the desorption of oxygen molecules from a silver surface was successfully visualized for the first time. The effects account for the shortcomings of conventional models of desorption.

Scientists unveil first method for controlling the growth of metal crystals
Researchers have announced the first ever method for controlling the growth of metal-crystals from single atoms. Developed at the University of Warwick, the method, called Nanocrystallometry, allows for the creation of precise components for use in nanotechnology. Professor Peter Sadler from the University's Department of Chemistry commented that 'The breakthrough with Nanocrystallometry is that it actually allows us to observe and directly control the nano-world in motion.'

Flatland optics with graphene
Researchers from CIC nanoGUNE, in collaboration with ICFO and Graphenea, introduce a platform technology based on optical antennas for trapping and controlling light with the one-atom-thick material graphene. The experiments show that the dramatically squeezed graphene-guided light can be focused and bent, following the fundamental principles of conventional optics. The work, published yesterday in Science, opens new opportunities for smaller and faster photonic devices and circuits.

NIST chip produces and detects specialized gas for biomedical analysis
A chip-scale device that both produces and detects a specialized gas used in biomedical analysis and medical imaging has been built and demonstrated at NIST. The new microfluidic chip produces magnetized xenon gas and then detects even the faintest magnetic signals from the gas. Magnetized xenon can be used as a marker for detecting biomolecules in liquids. Conventional systems for producing and using this gas can be as big as a car.

Don't blink! NIST studies why quantum dots suffer from 'fluorescence intermittency'
Researchers have found that a particular species of quantum dots that weren't commonly thought to blink, do. So what? Well, although the blinks are very short -- nanoseconds to milliseconds -- even brief fluctuations like these could signal trouble for using quantum dots in a quantum computer or between nodes of a future quantum Internet.

Illinois researchers combine weak chemical forces to strengthen novel imaging technology
Biomedical researchers at the University of Illinois have found ways to increase the effectiveness of certain contrast agents often used for imaging blood vessels and internal bleeding by associating them with nanoparticles. The contrast agent being used is packaged inside or bonded to the surface of microscopic particles, which can be designed to target certain regions of the body or prolong the agent's activity.

Capillary device significantly improves manufacture of quality liposomes
Widespread application for the manufactured vesicles known as liposomes has been hindered by limiting factors such as size inconsistency, structural instability and high production costs. A new approach developed by NIST and the University of Maryland overcomes these obstacles. The group's novel system is made up of bundled capillary tubes, costs less than a $1 to make and requires no special fabrication technology or expertise, yet consistently yields large quantities of uniform and sturdy vesicles.

Success of work team key in defining photonics career success, finds SPIE survey
Optics and photonics workers in government and military institutions, academia, and for-profits agree that the success of a team rates high among factors defining career success. But the latest findings in an annual Optics and Photonics Global Salary Report by SPIE, the international society for optics and photonics, reveal some significant differences among the sectors as well.

Professors' super waterproof surfaces cause water to bounce like a ball
Engineers like Julie Crockett and Dan Maynes have spent decades studying super-hydrophobic surfaces because of the plethora of real-life applications. And while some of this research has resulted in commercial products that keep shoes dry or prevent oil from building up on bolts, the duo of BYU professors are uncovering characteristics aimed at large-scale solutions for society.

Engineers build world's smallest, fastest nanomotor
Cockrell School of Engineering assistant professor Donglei 'Emma' Fan and her team have built the fastest, smallest and longest-running nanomotor to date. The UT Austin team's nanomotor is capable of drug delivery on a nanoscale. One day, nanomotors could lead to the development of tiny devices that seek out and treat cancer cells.

Liberating devices from their power cords
A new type of supercapacitor that can hold a charge when it takes a lickin' has been developed by engineers at Vanderbilt University. It is the first 'multi-functional' energy storage device that can operate while subject to realistic static and dynamic loads -- advancing the day when everything from cell phones to electric vehicles will no longer need separate batteries.

One small chip -- one giant leap forward for early cancer detection
An international team of researchers, led by ICFO- Institute of Photonic Sciences in Castelldefels, announce the successful development of a 'lab-on-a-chip' platform capable of detecting protein cancer markers in the blood using the very latest advances in plasmonics, nano-fabrication, microfluids and surface chemistry. The device is able to detect very low concentrations of protein cancer markers in blood, enabling diagnoses of the disease in its earliest stages.

Hope for paraplegic patients
People with severe injuries to their spinal cord currently have no prospect of recovery and remain confined to their wheelchairs. Now, all that could change with a new treatment that stimulates the spinal cord using electric impulses. The hope is that the technique will help paraplegic patients learn to walk again.

Tricking the uncertainty principle
Today, we can measure the position of an object with unprecedented accuracy, but the uncertainty principle places fundamental limits on our ability to measure. Noise that results from of the quantum nature of the fields used to make measurements imposes what is called the 'standard quantum limit.' This background noise keeps us from knowing an object's exact location, but a recent study provides a solution for rerouting some of that noise away from the measurement.

Stability lost as supernovae explode
Exploding supernovae are a phenomenon that is still not fully understood. In a recent paper published in EPJ E, Yves Pomeau and his colleagues from the CNRS provide a new model of supernovae represented as dynamical systems subject to a loss of stability, just before they explode. Because similar stability losses also occur in dynamical systems in nature, this model could be used to predict natural catastrophes before they happen.
