Gold nanoparticles improve photodetector performance
Using with nanoparticles of gold, researchers at the National University of Singapore have found a way to boost the performance of molybdenum disulfide MoS2 photodetectors, which are used in a wide range of technologies, such as environmental sensing, process control in factories, and optical communication devices. They describe this improvement in the journal Applied Physics Letters, which is produced by AIP Publishing.

Quantum of sonics: Bonded, not stirred
Researchers at McGill University have discovered a new way to join materials together using ultrasound. Ultrasound -- sound so high it cannot be heard -- is normally used to smash particles apart in water. In a recent study, the team of researchers, led by McGill professor Jake Barralet, from the faculties of Dentistry and Medicine, found that if particles were coated with phosphate, they could instead bond together into strong agglomerates, about the size of grains of sand. Their results are published in the journal Advanced Materials.

Nature: Elementary physics in a single molecule
A team of physicists has succeeded in performing an extraordinary experiment: They demonstrated how magnetism that generally manifests itself by a force between two magnetized objects acts within a single molecule. This discovery is of high significance to fundamental research and provides scientists with a new tool to better understand magnetism as an elementary phenomenon of physics. The researchers published their results in the latest issue of Nature Nanotechnology.

New techniques use lasers, LEDs, and optics to 'see' under the skin
A special section just published in the Journal of Biomedical Optics reports on new non-invasive optical techniques using lasers, light-emitting diodes, and spectroscopic methods to probe and render images from beneath the surface of the skin. The technologies have a wide variety of medical and cosmetic applications such as treating burns, identifying cancer, and speeding the healing of wounds.

NYU-Poly nano scientists reach holy grail in label-free cancer marker detection: Single molecules
Just months after setting a record for detecting the smallest single virus in solution, researchers at the Polytechnic Institute of New York University announced a new breakthrough: A nano-enhanced version of their biosensor detected a single cancer marker protein and even smaller molecules below the mass of all known markers. This achievement sets a new benchmark for the most sensitive limit of detection, and may significantly advance early disease diagnostics.

New NIST nanoscale indenter takes novel approach to measuring surface properties
Researchers from NIST and the University of North Carolina have demonstrated a new design for an instrument that makes sensitive measurements of the mechanical properties of thin films -- ranging from auto body coatings to microelectronic devices -- and biomaterials. The NIST instrument uses a unique technique for precisely measuring the depth of an indentation in a test surface with no contact of the surface other than the probe tip itself.

The ferromagnetic Kondo effect
A group of physicists that includes scientists of the International School for Advanced Studies of Trieste have shown how to obtain a particular case of a physical effect -- so far never observed in reality -- whose studies have earned a Nobel Prize. The scientists have also observed the response of the material subject to such effect. These observations will provide precious indications to the experimental physicists in order to verify, in the future, their theory.

Direct nitrogen fixation for low cost energy conversion
A simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets, which could be used in dye-sensitized solar cells and fuel cells, is published in Scientific Reports today. The work, carried out at Ulsan National Institute of Science and Technology in South Korea, could be a step towards replacing conventional platinum (Pt)-based catalysts for energy conversion.

Off-grid sterilization with Rice U.'s 'solar steam'
Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The "solar steam" sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat. The technology is described online in the Proceedings of the National Academy of Sciences Early Edition.

Chips that mimic the brain
Novel microchips imitate the brain's information processing in real time. Neuroinformatics researchers from the University of Zurich and ETH Zurich together with colleagues from the EU and US demonstrate how complex cognitive abilities can be incorporated into electronic systems made with so-called neuromorphic chips: They show how to assemble and configure these electronic systems to function in a way similar to an actual brain.

Unusual material expands dramatically under pressure
If you squeeze a normal object in all directions, it shrinks in all directions. But a few strange materials will actually grow in one dimension when compressed. A team of chemists has now discovered a structure that takes this property to a new level, expanding more dramatically under pressure than any other known material.

Milikelvins drive droplet evaporation
Evaporation is so common that everybody thinks it's a well understood phenomenon. Appearances can be, however, deceptive. Recently, a new, earlier not predicted mechanism of evaporation was discovered. Experiments and simulations performed at the Institute of Physical Chemistry of the Polish Academy of Sciences and the Institute of Physics of the PAS not only confirm its existence, but also indicate that it plays the crucial role in evaporation process in the nanoscale.

Penn researchers help show new way to study and improve catalytic reactions
A study by researchers at the University of Pennsylvania, the University of Trieste and Brookhaven National Laboratory has shown a way to precisely design the active elements of a certain class of catalysts, showing which parameters are most critical for improving performance. This highly controlled process could be a new paradigm for fine-tuning catalysts used in everything from making new materials to environmental remediation.

Another beautiful helix for biology, this time reminiscent of a parking garage
The endoplasmic reticulum is the protein-making factory within cells consisting of tightly stacked sheets of membrane studded with the molecules that make proteins. Now, researchers have refined a new microscopy imaging method to visualize exactly how the ER sheets are stacked, revealing that the 3D structure of the sheets resembles a parking garage. This structure allows for the dense packing of ER sheets, maximizing the amount of space available for protein synthesis.

Ironing out the origins of wrinkles, creases and folds
Engineers from Brown University have mapped out the amounts of compression required to cause wrinkles, creases, and folds to form in rubbery materials. The findings could help engineers control the formation of these structures, which can be useful in designing nanostructured materials for flexible electronic devices or surfaces that require variable adhesion.

Nano drug crosses blood-brain tumor barrier, targets brain-tumor cells and blood vessels
The blood-brain barrier protects the brain from poisons but also prevents drugs from reaching brain tumors. A preclinical study shows that an experimental nanotechnology drug called SapC-DOPS crosses the tumor blood-brain barrier, targets brain-tumor cells and retards growth of tumor blood vessels. The findings also show why the agent targets tumor cells and recommend the drug's further development as a novel treatment for glioblastoma.
