Lifting the lid on silicon batteries
Resolving the mystery of what happens inside batteries when silicon comes into with lithium could accelerate the commercialisation of next-generation high capacity batteries, for use in mobile phones and other applications. Using this technique will help make battery design much more systematic, and less trial and error Ken Ogata Next-generation batteries based on silicon have come one step closer to commercial reality, after the mystery surrounding what is happening inside batteries when silicon comes into with lithium has been understood in unprecedented detail.

A new wrinkle in the control of waves
Flexible materials could provide ways to manipulate sound and light. Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method, developed by researchers at MIT, could eventually find applications from nondestructive testing of materials to sound suppression, and could also provide new insights into soft biological systems and possibly lead to new diagnostic tools.

Researchers develop new method to control nanoscale diamond sensors
Technique allows tiny sensors to monitor small changes in magnetic fields, such as when neurons transmit electrical signals. Diamonds may be a girl's best friend, but they could also one day help us understand how the brain processes information, thanks to a new sensing technique developed at MIT. A team in MIT's Quantum Engineering Group has developed a new method to control nanoscale diamond sensors, which are capable of measuring even very weak magnetic fields.

When nanotech meets quantum physics in one dimension
How would electrons behave if confined to a wire so slender they could pass through it only in single-file? The question has intrigued scientists for more than half a century. In 1950, Japanese Nobel Prize winner Sin-Itiro Tomonaga, followed by American physicist Joaquin Mazdak Luttinger in 1963, came up with a mathematical model showing that the effects of one particle on all others in a one-dimensional line would be much greater than in twoor three-dimensional spaces.

Material like '3D graphene' promises new electronics
Material like '3D graphene' promises new electronics
The discovery of a material that has a similar electronic structure to graphene but can exist in three dimensions, instead of a flat sheet like graphene, could lead to faster transistors and more compact hard drives. An international team, led by scientists from Oxford University, Stanford University, and Berkeley Lab's Advanced Light Source, has discovered that sodium bismuthate can exist as a form of quantum matter called a three-dimensional topological Dirac semi-metal (3DTDS).

Natural 3D Counterpart to Graphene Discovered
Natural 3D Counterpart to Graphene Discovered
The discovery of what is essentially a 3D version of graphene - the 2D sheets of carbon through which electrons race at many times the speed at which they move through silicon – promises exciting new things to come for the high-tech industry, including much faster transistors and far more compact hard drives.

Superconducting spintronics pave way for next-generation computing
A breakthrough for the field of Spintronics, a new type of technology which it is widely believed could be the basis of a future revolution in computing, has been announced by scientists in Cambridge. The results offer a glimpse into a future in which super-computing could be far more energy-efficient Jason Robinson The research, reported , provides the first evidence that superconductors could be used as an energy-efficient source for so-called "spin-based" devices, which are already starting to appear in microelectronic circuits.

A Deeper Look at Interfaces: Researchers at Berkeley Lab's Advanced Light Source Develop New Technique for Probing Subsurface Electronic Structure
A Deeper Look at Interfaces: Researchers at Berkeley Lab’s Advanced Light Source Develop New Technique for Probing Subsurface Electronic Structure
"The interface is the device," Nobel laureate Herbert Kroemer famously observed, referring to the remarkable properties to be found at the junctures where layers of different materials meet. In today's burgeoning world of nanotechnology, the interfaces between layers of metal oxides are becoming increasingly prominent, with applications in such high-tech favorites as spintronics, high-temperature superconductors, ferroelectrics and multiferroics.
