Klappe, die erste... Der Startschuss fuer "nanospots" ist gefallen. Es handelt sich um den Wettbewerb zum 1. Nano-Kurzfilm-Festival fuer (Nachwuchs-)Wissenschaftler, mitinitiiert von der Martin-Luther-Universitaet Halle-Wittenberg und gefoerdert von der Volkswagenstiftung. Als Hauptgewinn winken 5000 Euro fuer den besten Spot zum Thema "Leben mit Nano: Der Mensch zwischen Natur und Hightech".
Led by a group at the University of Maryland (UMd), a multi-institution team of researchers has combined modern materials research and an age-old metallurgy technique to produce an alloy that could be the basis for a new class of sensors and micromechanical devices controlled by magnetism.
A team of university researchers, aided by scientists at the National Institute of Standards and Technology (NIST), have succeeded in integrating a new, highly efficient piezoelectric material into a silicon microelectromechanical system (MEMS). This development could lead to significant advances in sensing, imaging and energy harvesting.
In a cooperative between Helmholtz Zentrum Berlin (HZB) and the Federal Institute for Materials Research and Testing (BAM), scientists have produced the first three-dimensional representations of ruthenium catalyst particles only two nanometres in diameter using electron tomography.
In a series of observations and experiments, engineers at Brown University and in Korea have discovered unusual properties in wrinkles and folds at the nanoscale. The researchers report that wrinkles created on super-thin films have hidden long waves that lengthen even when the film is compressed. The team also discovered that when folds are formed in such films, closed nanochannels appear below the surface, like thousands of super-tiny pipes.
Conventional wisdom would say that blocking a hole would prevent light from going through it, but Princeton University engineers have discovered the opposite to be true. A research team has found that placing a metal cap over a small hole in a metal film does not stop the light at all, but rather enhances its transmission.
A magnetic force microscope (MFM) can determine the distribution of stray fields at a level of tens of nanometers near the surface of magnetic films, and therefore is an effective tool for observing the domain structures in magnetic grains of submicrometer size.
Professor Kaustav Banerjee, a professor of electrical and computer engineering and Director of the Nanoelectronics Research Lab at the University of California, Santa Barbara, has been named winner of the 2011 international research award by the Electrostatic Discharge Association (ESDA).
When a skier rushes down a ski slope or a skater glides across an ice rink, a very thin melted layer of liquid water forms on the surface of the ice crystals, which allows for a smooth glide instead of a rough skid. In a recent experiment, scientists have discovered that the interface between the surface and bulk electronic structures of certain crystalline materials can act in much the same way.
