Magnetism relieves electrons of their resistance

Physics is sometimes just like a criminal investigation. Researchers gather one piece of evidence after another in order to solve a mystery - for example, the question as to how unconventional superconductivity is caused, something which is also of particular interest for technical applications. An international team involving scientists at the Max Planck Institute for Chemical Physics of Solids has now provided the strongest evidence yet that magnetic interactions can bring about this form of zero-resistance current transport - something that physicists have been gathering evidence for, for some time.

Alternating stacks of planar cations and dipyrrole-containing anions provides concept for new materials

Pyrroles, which are rings containing one nitrogen and four carbon atoms, are essential components of our red hemoglobin as well as the green chlorophyll in plants. Japanese researchers have now also used this molecular motif in the construction of new nanostructured materials: They combined planar pyrrole-containing negatively charged complexes with similarly planar, positively charged organic ions.

Singapore-US partnership take lead in establishing design principles for nanowire sensors

The Institute of Microelectronics (IME), an institute of the Agency for Science, Technology and Research (A*STAR), and the University of Illinois at Urbana-Champaign (Illinois) have entered into a research collaboration focussed on identifying and defining the ground rules for the systematic optimisation of nanowire sensor design as well as the techniques for batch fabrication.

Spontaneously chain-reacting molecule a boost for nano-circuitry

A new paper describes, for the first time, a simple molecule that each time it chemically reacts with a surface prepares a hospitable neighbouring site at which the next incoming molecule reacts. Accordingly, these molecules, when simply dosed (blindly) on the surface, spontaneously grow durable 'molecular-chains'. These molecular chains are the desired prototypes of nano-wires.

Vibrating nanorods measure thin films for microcircuits

A key step in many nanofabrication processes is to create thin films, sometimes only one molecule thick, by a method known as atomic layer deposition. Researchers at Cornell and Tel Aviv University have developed a new tool for nanofabricators to test the physical properties of such films.
