Patterns of particles generated by surface charges
Every day we can see order turn into disorder -- for instance when intricate ice crystals melt. But sometimes, disorder can also turn into perfectly ordered structures. At the Vienna University of Technology, physicists studied particles with inhomogeneous surface charge which can spontaneously create two dimensional patterns. This may create new kinds of materials or even filters with tunable properties.

Physicists at Mainz University build pilot prototype of a single ion heat engine
Scientists at Johannes Gutenberg University Mainz and the University of Erlangen-Nuremberg are working on a heat engine that consists of just a single ion. Such a nano-heat engine could be far more efficient than, for example, a car engine or a coal-fired power plant.

Capturing ultrasharp images of multiple cell components at once
A new microscopy method could enable scientists to generate snapshots of dozens of different biomolecules at once in a single human cell, a team from the Wyss Institute of Biologically Inspired Engineering at Harvard University reported Sunday in Nature Methods. Such images could shed light on complex cellular pathways and potentially lead to new ways to diagnose disease, track its prognosis, or monitor the effectiveness of therapies at a cellular level.

Self-aligning DNA wires for application in nanoelectronics
Since miniaturization in microelectronics is starting to reach physical limits, researchers seek new methods for device fabrication. One candidate is DNA origami in which strands of the biomolecule self-assemble into arbitrarily shaped nanostructures. The formation of entire circuits, however, requires the controlled positioning of these DNA structures on a surface -- which is only possible using elaborate techniques. Researchers at Helmholtz-Zentrum Dresden-Rossendorf have come up with a simpler strategy which combines DNA origami with self-organized pattern formation.

Faster X-ray technology paves the way for better catalysts
By using a novel X-ray technique, researchers have observed a catalyst surface at work in real time and were able to resolve its atomic structure in detail. The new technique, pioneered at Deutsches Elektronen-Synchrotron DESY's X-ray light source PETRA III, may pave the way for the design of better catalysts and other materials on the atomic level. The Swedish-German research team around lead author Dr. Johan Gustafson of Lund University present their work in the journal Science.

DNA-built nanostructures safely target, image cancer tumors
A team of researchers at the University of Toronto has discovered a method of assembling "building blocks" of gold nanoparticles as the vehicle to deliver cancer medications or cancer-identifying markers directly into cancerous tumors. The study, led by Warren Chan, professor at the Institute of Biomaterials & Biomedical Engineering and the Donnelly Centre for Cellular & Biomolecular Research, appears in an article in Nature Nanotechnology this week.

Graphene-like material made of boron a possibility, experiments suggest
Graphene, a sheet of carbon one atom thick, may soon have a new nanomaterial partner. In the lab and on supercomputers, chemists from Brown University have determined that a cluster of 36 boron atoms forms a flat disc with a hexagonal hole in the middle. The shape fits theoretical predictions for a potential new nanomaterial: "borophene." Findings are reported in Nature Communications.

New quantum dots herald a new era of electronics operating on a single-atom level
New types of solotronic structures, including the world's first quantum dots containing single cobalt ions, have been created and studied at the Faculty of Physics at the University of Warsaw. The materials and elements used to form these structures allow us forecast new trends in solotronics -- a field of experimental electronics and spintronics of the future, based on operations occurring on a single-atom level.

The origin of the evil conformation
Prions form when normal proteins acquire a misfolded conformation and cause incurable neurodegenerative diseases. A team of scientists from SISSA has recently published a study that investigates the early events of the conversion from the normal to the disease-causing form of the prion protein.

New microscopy technique improves imaging at the atomic scale
When capturing images at the atomic scale, even tiny movements of the sample can result in skewed or distorted images -- and those movements are virtually impossible to prevent. Now microscopy researchers at North Carolina State University have developed a new technique that accounts for that movement and eliminates the distortion from the finished product.

Molecules as circuits
With traditional technology, this miniaturization is hampered by the limits imposed by physics, but some have thought of using molecules as circuits. If molecules are to be able to do this efficiently, they need to improve their poor conduction ability. In a study published in the Proceedings of the National Academy of Sciences, a team of researchers featuring Ryan Requist, Erio Tosatti and Michele Fabrizio of the International School of Advanced Studies shows how the Kondo effect can improve the conductivity of some magnetic molecules.
