Chemiker der Uni Jena und des Forschungsbereichs Biomaterialien von INNOVENT e. V. stellen einen Wirkstofftraeger auf Nanofaserbasis vor, der Stickstoffmonoxid nach einer Bestrahlung mit UV-A-Licht freisetzt. Grundlage dafuer ist ein neuer, photolabiler Ruthenium-Nitrosyl-Komplex, der in Polylaktid-Nanofasern eingebettet ist.
A presentation on the new European Commission framework programme Horizon 2020 will lead off the more than 1,400 talks at the upcoming SPIE Photonics Europe international congress on materials, nanotechnology, biophotonics, semiconductors, lasers, multimedia, and imaging. The meeting will be held at the Square Brussels Meeting Centre 16-19 April.
Butterfly wings may rank among the most delicate structures in nature, but they have given researchers powerful inspiration for new technology that doubles production of hydrogen gas - a green fuel of the future - from water and sunlight.
Motivated by the desire to determine the simplest 3-D structure that could take advantage of mechanical instability to collapse reversibly, a group of engineers at MIT and Harvard University were stymied - until one of them happened across a collapsible, spherical toy that resembled the structures they'd been exploring, but with a complex layout of 26 solid moving elements and 48 rotating hinges.
Many in the semiconductor field think that the industry is fast approaching the physical limits of transistor miniaturization. The major problem in modern transistors is power leakage leading to the generation of excessive heat from billions of transistors in close proximity. Recent advances at Notre Dame and Penn State show that tunneling field effect transistors are on track to solve these problems by delivering comparable performance to today's transistors, but with much greater energy efficiency.
Medicine's recipe for keeping older people active and functioning in their homes and workplaces - and healing younger people injured in catastrophic accidents - may include "noodle gels" and other lab-made invisible filaments that resemble uncooked spaghetti with nanoscale dimensions.
The European Commission has released the the third edition of the Nanosafety Cluster compendium. It documents the status of important projects on nanomaterial toxicity and exposure monitoring, integrated risk management, research infrastructure and coordination and support activities.
A company that developed a monitoring device to reduce back pain and promote good posture just received a $10,000 boost for winning the grand prize in the 13th Annual Elevator Competition hosted by Wake Forest University Schools of Business.
The phenomenon of friction, when studied on a nanoscale, is more complex than previously thought. When friction occurs, an object does not simply slide its surface over that of another, it also makes a slight up-and-down movement. This finding completes a centuries-old theory of friction dating to 1699 and uncovers a gap in contemporary thinking on friction.
