Ketchup turns somersaults
Blood, paint or ketchup are complex liquids composed of several different components. For the construction of pumps, or the improvement of technical processes scientists and engineers need description models. They make the special properties of such liquids predictable. Researchers at the Technische Universitaet Muenchen and the Federal Institute of Technology Zurich have developed such a model. In the current issue of the prestigious journal "Physical Review Letters" they present it.

Trackable drug-filled nanoparticles -- a potential weapon against cancer
Tiny particles filled with a drug could be a new tool for treating cancer in the future. A new study published by Swedish scientists in Particle & Particle Systems Characterization shows how such nanoparticles can be combined to secure the effective delivery of cancer drugs to tumor cells -- and how they can be given properties to make them visible in MR scanners and thus be rendered trackable.

Invention opens the way to packaging that monitors food freshness
Millions of tons of still-edible food are thrown away because the "best before" date has passed. Wouldn't it be handy if the packaging could really "test" whether the contents are still safe to eat? Eindhoven University of Technology, Universitá di Catania, CEA-Liten and STMicroelectronics have invented a circuit that makes this possible: A plastic analog–digital converter. This brings plastic sensor circuits costing less than one euro cent within reach.

Connecting the (quantum) dots
University of Pittsburgh and Delft University of Technology researchers reveal in the Feb. 17 online issue of Nature Nanotechnology a new method that better preserves the units necessary to power lightning-fast electronics, known as qubits. Hole spins, rather than electron spins, can keep quantum bits in the same physical state up to 10 times longer than before, the report finds.

Blueprint for an artificial brain
Senior lecturer Dr. Andy Thomas from Bielefeld University's Faculty of Physics is experimenting with memristors -- electronic microcomponents that imitate natural nerves. Thomas and his colleagues proved that they could do this a year ago. They constructed a memristor that is capable of learning. Andy Thomas is now using his memristors as key components in a blueprint for an artificial brain.

Light particles illuminate the vacuum
Researchers from the Finnish Aalto University and the Technical Research Centre of Finland succeeded in showing experimentally that vacuums have properties not previously observed. According to the laws of quantum mechanics, it is a state with abundant potentials. Vacuums contain momentarily appearing and disappearing virtual pairs, which can be converted into detectable light particles.

UC Santa Barbara scientists develop a whole new way of harvesting energy from the sun
A new method of harvesting the sun's energy is emerging, thanks to scientists at UC Santa Barbara's departments of chemistry, chemical engineering, and materials. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more robust than many of the semiconductors used in conventional methods. The researchers' findings are published in the latest issue of the journal Nature Nanotechnology.

Laser mastery narrows down sources of superconductivity
Uncovering the mechanism behind high-temperature superconductivity -- a phenomenon with tremendous value to advances in energy efficiency and sustainability -- remains one of the greatest and most pressing puzzles in physics. Now, using precise laser pulses and atomically perfect 2D materials, collaborating scientists have ruled out one possible source of HTS: Fleeting fluctuations called charge-density waves.

UCLA researchers further refine 'NanoVelcro' device to grab single cancer cells from blood
Researchers at UCLA report that they have refined a method they previously developed for capturing and analyzing cancer cells that break away from patients' tumors and circulate in the blood. With the improvements to their device, which uses a Velcro-like nanoscale technology, they can now detect and isolate single cancer cells from patient blood samples for analysis.

Light from silicon nanocrystal LEDs
Silicon nanocrystals have a size of a few nanometers and possess a high luminous potential. Scientists of KIT and the University of Toronto/Canada have now succeeded in manufacturing silicon-based light-emitting diodes. They are free of heavy metals and can emit light in various colors. The team of chemists, materials researchers, nanoscientists, and opto-electronic experts presents its development in the "Nano Letters" journal (DOI: 10.1021/nl3038689).

Researchers 'nanoweld' by applying light to aligned nanorods in solid materials
Researchers from North Carolina State University have developed a way to melt or "weld" specific portions of polymers by embedding aligned nanoparticles within the materials. Their technique, which melts fibers along a chosen direction within a material, may lead to stronger, more resilient nanofibers and materials.

Titanium dioxide nanoreactor
Tiny particles of titanium dioxide are found as key ingredients in wall paints, sunscreens, and toothpaste; they act as reflectors of light or as abrasives. However with decreasing particle size and a corresponding change in their surface-to-volume ratio, their properties change so that crystalline titanium dioxide nanoparticles acquire catalytic ability: Activated by the UV component in sunlight, they break down toxins or catalyze other relevant reactions.

Painting with catalysts: Nano-engineered materials for detoxifying water by use of sunlight
Only light, aerial oxygen, and a catalyst are needed to remove pollutants from water. RUB researchers led by Prof. Radim Beránek collaborate with colleagues from seven different countries in order to develop a photocatalyst that is efficient enough to be profitable. The aim is to implement the newly developed photocatalysts into a liquid paint with which photoreactors can easily be coated. The EU supports the project within its 7th Framework Programme with 3.7 million Euro funding for three years.
