The generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers have now discovered how to control this effect in nanoscale semiconductors called quantum dots, enabling the development of incredibly tiny new products.
In einem interdisziplinaeren Projekt ist es Wissenschaftlern des KIT gelungen, eine neue Erscheinungsform von optischen Resonatoren zu schaffen: Mikrokelche. Diese Polymerstrukturen sind durch ihre Form und ihre glatte Oberflaeche besonders effiziente Quellen fuer Laserlicht. Zudem haben sie das Potenzial kleinste Bio-Molekuele, Viren oder Gefahrstoffe nachzuweisen.
It's the first day of school at the Joint School of Nanoscience and Nanoengineering in Greensboro. That's not just for the new school year; it's the first day of school ever for one of the UNC system's most innovative educational initiatives.
The DNA genomes of organisms whose cells possess nuclei are packaged in a highly characteristic fashion. Most of the DNA is tightly wrapped around protein particles called nucleosomes, which are connected to each other by flexible DNA segments, like pearls on a necklace. This arrangement plays a major role in deciding which genes are actively expressed, and thus which proteins can be synthesized in a given cell. Researchers have recently developed a model which explains the distribution of nucleosomes around the functionally crucial transcription start sites.
Maryland Gov. Martin O'Malley has appointed Peter Searson and Steve Desiderio, two researchers from The Johns Hopkins University, to serve on a special task force to study the benefits of nanobiotechnology.
A new approach to building an 'artificial nose' - using fluorescent compounds and DNA - could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists.
For their look into the nanoworld, researchers used a scanning tunneling microscope. Its thin metal tip scans the specimen surface like the needle of a record player and registers the atomic irregularies and differences of approximately one nanometer with minuscule electric currents.
nfrastructure Technologies is the first company to sign on to the Assembly's inter-regional nanotechnology-partnership initiative. The company will occupy a newly created space at SUNYIT; planning of which is underway.
Leading scientists from neuroscience, nanoscience, astrophysics, computer science and engineering are gathering to discuss this question in Tromso, Norway, continuing a dialogue that began at last year's Kavli Futures Symposium.
A record number of 16 papers with imec authors has been accepted for this year's IEEE International Electron Devices Meeting (IEDM), being held Dec 6 - 8 in San Francisco. Both ITRS-related as well as More-than-Moore-related research papers have been accepted.
These workshops brief participants on what is nanotechnology and manufactured nanomaterials, what are some of the potential risks from nanotechnologies and manufactured nanomaterials (e.g. to the environment or human health) and benefits (e.g. decreased costs of low-maintenance products, or use in environmental remediation) of nanotechnology and nanomaterials.
