Scientists have cracked a 35-year-old mystery about the workings of the natural motors that are serving as models for development of a futuristic genre of synthetic nanomotors that pump therapeutic DNA, RNA or drugs into individual diseased cells.
European researchers in the Nanodevice project are investigating the safety aspects of nanomaterial production. Their plan laid down in 2009 was to develop new concepts, reliable methods and portable devices for detecting, analysing and monitoring airborne ENMs in the workplace. The latest feedback from the team suggests the project has delivered on its promise.
Entwicklung der weltweit ersten ultraflachen, bipolaren Meta-Linse gelungen - Material aus Glas und Gold 2.000 Mal dünner als menschliches Haar - Nutzung in Photonik bei optischen Schaltkreisen und Leuchtdioden.
EPFL scientists have combined two materials with advantageous electronic properties -- graphene and molybdenite -- into a flash memory prototype that is very promising in terms of performance, size, flexibility and energy consumption.
The realisation of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from 'solid-state' chips, bringing us closer to the quantum 'internet'.
Better diagnosis and treatment of cancer could hinge on the ability to better understand a single cell at its molecular level. New research offers a more comprehensive way of analyzing one cell's unique behavior, using an array of colors to show patterns that could indicate why a cell will or won't become cancerous.
When researchers at the University of Massachusetts Amherst led by microbiologist Derek Lovley discovered that the bacterium Geobacter sulfurreducens conducts electricity very effectively along metallic-like "microbial nanowires", they found physicists quite comfortable with the idea of such a novel biological electron transfer mechanism, but not biologists.
To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current.
