Science
Faster design -- better catalysts
While the cleaning of car exhausts is among the best known applications of catalytic processes, it is only the tip of the iceberg. Practically the entire chemical industry relies on catalytic reactions. Therefore, catalyst design plays a key role in improving these processes. An international team of scientists has now developed a concept, that elegantly correlates geometric and adsorption properties. They validated their approach by designing a new platinum-based catalyst for fuel cell applications.

Breakthrough for electrode implants in the brain
For nearly nine years, researchers at Lund University have been working on developing implantable electrodes that can capture signals from single neurons in the brain over a long period of time -- without causing brain tissue damage. They are now one big step closer to reaching this goal, and the results are published in the scientific journal Frontiers in Neuroscience.

Room temperature magnetic skyrmions, a new type of digital memory?
An exotic, swirling object with the sci-fi name of a 'magnetic skyrmion' could be the future of nanoelectronics and memory storage. Physicists at UC Davis and the National Institute of Standards and Technology have now succeeded in making magnetic skyrmions, formerly found at temperatures close to absolute zero, at room temperature.

Energy researchers discover new structure for bimetallic catalysts
Dion Vlachos, who directs the Catalysis Center for Energy Innovation at the University of Delaware, uses computational techniques to predict how nanoscale materials will behave and recently made a surprising discovery about the structure of bimetallic catalysts. An imperfect surface may produce a better catalyst.

End to contaminated drinking water
As things stand, a suspected contamination of drinking water requires that a technician first be sent out to take samples from the water supply. The samples are then cultured and analysed in the laboratory. Only after several days does it become clear whether the water is contaminated and which bacterium is the offender.

New microscopy technology augments surgeon's view for greater accuracy
Researchers at the University of Arizona in Tucson have developed a prototype of a new microscope technology that could help surgeons work with a greater degree of accuracy in diagnosing cancer or performing brain surgery or other procedures. The new technology, call augmented microscopy, is reported today in the Journal of Biomedical Optics, published by SPIE, the international society for optics and photonics.

Double the (quantum) fun
A group of researchers in Japan is exploring the behavior of a certain type of SET (single-electron transistor) made from two quantum dots, which are bits of material so small they start to exhibit quantum properties. The group has produced a detailed analysis of the electrical characteristics of the so-called double-quantum-dot SETs, which could help researchers design better devices to manipulate single electrons. They report their findings in the Journal of Applied Physics.

Professor Nanfang Yu wins DARPA Young Faculty Award for optoelectronics research
Columbia Engineering applied physics professor Nanfang Yu has won the prestigious DARPA Young Faculty Award, which will support his work on metasurface-based flat optical modulators, using strong interactions between light and 2-D-structured materials to control light at will. Yu hopes to demonstrate spatial light modulators -- high-speed and lightweight optoelectronic devices -- that are crucial for light detection and ranging, technology useful for a wide range of applications, including remote sensing, navigation, and surveillance.

ORNL researchers find 'greener' way to assemble materials for solar applications
The efficiency of solar cells depends on precise engineering of polymers that assemble into films 1,000 times thinner than a human hair. Today, formation of that polymer assembly requires solvents that can harm the environment, but scientists at the Department of Energy's Oak Ridge National Laboratory have found a 'greener' way to control the assembly of photovoltaic polymers in water using a surfactant -- a detergent-like molecule -- as a template.

Observing the unobservable: Researchers measure electron orbitals of molecules in 3-D
Electron orbitals provide information on the whereabouts of the electrons in atoms and molecules. Scientists from the University of Graz, Forschungszentrum Jülich, and the Physikalisch-Technische Bundesanstalt have now succeeded in experimentally recording these structures in all three dimensions. They achieved this by further developing a method they had already applied two years ago to make these orbitals visible in two dimensions. Their findings have now been published in the scientific journal Nature Communications.

Electron tomography with 3,487 images in 3.5 seconds
Scientists from the Ernst Ruska-Centre used a transmission electron microscope to record almost 3,500 images in 3.5 seconds for the reconstruction of a 3-D electron tomogram. Previously, 10 to 60 minutes and a ten-fold greater electron dose were required to record such image sequences. The new capability is particularly suitable for examining cells, bacteria, viruses and dynamic processes, such as chemical reactions and electronic switching phenomena. The findings have been published in Scientific Reports.

Semiconductor nanoparticles show high luminescence in a polymer matrix
Toyohashi Tech researchers in cooperation with researchers at the National Institute of Technology, Kurume College have demonstrated the formation of composite nanoparticles of luminescent ZnO quantum dots and polymer by dispersion polymerization in supercritical CO2. Embedding quantum dots in polymeric matrices enhances their stability and prevents agglomeration. This research shows that the supercritical-fluid-assisted process provides an environmentally benign process for producing stabilized luminescent materials.

Phoenix effect: Resurrected proteins double their natural activity
Researchers from ITMO University and the Hebrew University in Jerusalem discovered a novel mechanism of protein resurrection, which not only restores the active function of the protein, but also increases its original activity by almost two times. The scientists termed the observed phenomenon the Phoenix effect, drawing from the cross-culture mythology which uses the Phoenix legend as a symbol for rebirth into even stronger self. The results of the study were published today in Scientific Reports.
