An insect's internal chemicals can be converted to electricity, potentially providing power for sensors, recording devices or to control the bug, a group of researchers at Case Western Reserve University report.
Researchers at Northwestern University have recently reported that individual gallium nitride nanowires show strong piezoelectricity - a type of charge-generation caused by mechanical stress - in three dimensions.
Die aktuellen Entwicklungen in der Kombination von Fluoreszenztomographie und klassischer Mikroskopie setzen neue Massstaebe in der Infektionsforschung. Die modernen bildgebenden Verfahren und ihre Ergebnisse werden Thema des internationalen Symposiums "Imaging Infection 2012" sein.
The smallest wires ever developed in silicon - just one atom tall and four atoms wide - have been shown by a team of researchers from the University of New South Wales, Melbourne University and Purdue University to have the same current-carrying capability as copper wires.
In an effort to make data storage more cost-effective, a group of researchers from National Tsing Hua University in Taiwan and the Karlsruhe Institute of Technology in Germany have created a DNA-based memory device that is "write-once-read-many-times" (WORM), and that uses ultraviolet (UV) light to make it possible to encode information.
Engineers at the University of Houston have used quantum mechanical calculations to show that, merely by creating holes of a certain configuration in a sheet of graphene, they can coax graphene into behaving like a piezoelectric material.
In a just released report, the U.S. Environmental Protection Agency Office of Inspector General finds that EPA does not currently have sufficient information or processes to effectively manage the human health and environmental risks of nanomaterials.
A quick, inexpensive and highly sensitive test that identifies early-stage disease markers or other molecules in low-concentrations, could be the result of a new nanomechanical biosensor developed at Cornell.
Der Experimentierkoffer SimplyNano 1 enthaelt acht spannende Experimente aus der Welt der Nanotechnologie. Der Koffer richtet sich besonders an Lernende im 7. bis 10. Schuljahr und will einfache Phaenomene der Nanotechnologie vorstellen.
In a new review paper, Hiroshi Fudouzi at National Institute for Materials Science (NIMS) in Japan describes the challenges facing materials scientists for the realization of photonic crystals based on design of bioinspired structural color.
