With the slogan 'New Ideas for Industry' Nanofair has established itself as one of the premier conferences on nanotechnology. The Fraunhofer IWS Dresden, in partnership with the City of Dresden`s Department of Economic Development and several others, is organizing this event. 2014 marks the 10th anniversary of Nanofair. The Call for Papers is now open.
Scientists prepared magnetic shell cross-linked knedel-like nanoparticles for removal of environmental pollutants and determined their loading capabilities. These well-defined nanoparticles showed efficient oil sorption capacity of 10-fold their initial dry weight when introduced into an aqueous environment polluted with a complex crude oil.
Researchers have introduced a microscopic pump that is based on polymer gel microparticles and starts up when irradiated with UV light. The extraordinary thing about this device is that the material continues to pump when the stimulus is removed.
Polyethylen ist ein Massenkunststoff, der in vielen Haushaltsgegenständen zu finden und daher besonders preiswert herzustellen ist. Einem Forscherteam aus Konstanz, Bayreuth und Berlin gelang es nun, aus diesem Kunststoff einen idealen Nanokristall zu synthetisieren.
In a materials science laboratory at Harvard University, a transparent disk connected to a laptop fills the room with music - it's the 'Morning' prelude from Peer Gynt, played on an ionic speaker. No ordinary speaker, it consists of a thin sheet of rubber sandwiched between two layers of a saltwater gel, and it's as clear as a window.
An international team of researchers at Vienna University of Technology in Austria and at Princeton University in the USA has confirmed theoretically-predicted interactions between single oxygen molecules and crystalline titanium dioxide.
Physicists have theorized that topological crystalline insulators possess unique surface states as a result of crystalline symmetry. An international team of researchers has confirmed that experimental signature and revealed that disrupting the lattice-like structure imparts mass upon previously mass-less electrons. Furthermore, the researchers found manipulating structural symmetry offers a degree of control over the electronic phases of the solid-state material.
Taking cues from nature, Northwestern University researchers have tested a new method for achieving particular molecular properties: by changing the geometry of the surface to which the molecule is bound.
Groningen scientists have found an explanation for a mystery that has been puzzling the physics community since 1995. They explain why electrons pass through nanowires less smoothly than expected. The observations will affect nanoelectronics.
A novel method for finding and delivering healing drugs to newly formed microcracks in bones has been invented by a team of chemists and bioengineers at Penn State University and Boston University. The method involves the targeted delivery of the drugs, directly to the cracks, on the backs of tiny self-powered nanoparticles. The energy that revs the motors of the nanoparticles and sends them rushing toward the crack comes from a surprising source - the crack itself.
The coherence of quantum systems is the foundation upon which hardware for future information technologies is based. Quantum information is carried by units called quantum bits, or qubits. They can be used to secure electronic communications - and they enable very fast searches of databases. But qubits are also very unstable. Physicists have now developed a new electronic component which will help to deal with this problem.
Quantum point contacts in electrical circuits are narrow constrictions that can impede the passage of electrons in unexpected ways. Physicists have now achieved a detailed microscopic understanding of this transport anomaly.
While it has long been possible to make complicated 3D structures with many mask layers or expensive grayscale masks, the new technique enables researchers to etch trenches and other high aspect ratio structures with nanometer scale features without using masks and in only two process stages.
