A team of researchers have directly observed a rare quantum effect that produces a repeating butterfly-shaped energy spectrum, confirming the longstanding prediction of this quantum fractal energy structure called Hofstadter's butterfly.
Materials nanoarchitectonics has led to important innovations in the design and construction of systems in nanoelectronics, nanomachinery, and energy conversion. Recent publications point to the fact that the same approach may be applied successfully to other fields.
In search of low-friction components for ever smaller components, a team of physicists led by the professors Thorsten Hugel and Alexander Holleitner now discovered a previously unknown type of friction that they call 'desorption stick'.
By adding semiconducting nanoparticles to polymers, the Materials + Technologies Research Group (GMT) of the Polytechnical College of San Sebastian of the UPV/EHU-University of the Basque Country has created nanostructured composite materials with specific optical and electrical properties that vary according to size.
Imagine having a wafer-thin touchscreen on your sleeve which, like a scene out of a Philip K. Dick novel, gives you all the functionality of a smartphone without the awkwardness of a cumbersome battery. The best part about this scenario is it may not be as far from reality as you think.
A class of water-loving, jelly-like materials with uses ranges ranging from the mundane, such as superabsorbent diaper liners, to the sophisticated, such as soft contact lenses, could be tapped for a new line of serious work: testing the biological effects of nanoparticles now being eyed for a large variety of uses.
Researchers at Queen's University Belfast have devised a 'magic bullet' nanomedicine which could become the first effective treatment for Acute Lung Injury or ALI, a condition affecting 20 per cent of all patients in intensive care.
Northwestern University scientists have struck gold in the laboratory. They have discovered an inexpensive and environmentally benign method that uses simple cornstarch - instead of cyanide - to isolate gold from raw materials in a selective manner.
CEA-Leti said today that Europe is strongly positioned to design and manufacture volume silicon photonics devices because of the success of the recently completed HELIOS program. The EUR 8.5 million European Commission project developed a complete design and fabrication supply chain for integrating a photonic layer with a CMOS circuit, using microelectronics fabrication processes.
A new study by University of Georgia researchers documents a technological breakthrough: Synthetic high density lipoprotein nanoparticles. A completely biodegradable synthetic version of the so-called good cholesterol, the nanoparticles represent a potential new detection and therapy regimen for atherosclerosis.
