Pressure cooking to improve electric car batteries
Researchers at the University of California, Riverside's Bourns College of Engineering have redesigned the component materials of the battery in an environmentally friendly way to solve some of the problems associated with electric car batteries. By creating nanoparticles with a controlled shape, they believe smaller, more powerful and energy efficient batteries can be built.

Penn produces graphene nanoribbons with nanopores for fast DNA sequencing
Researchers at the University of Pennsylvania have made an advance towards realizing a new gene sequencing technique based on threading DNA through a tiny hole in a layer of graphene. Earlier versions of the technique only made use of graphene's unbeatable thinness, but the Penn team's research shows how the material's unique electrical properties may be employed to make faster and more sensitive sequencing devices.

Nature: Single-atom bit forms smallest memory in the world
One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years. However, researchers from KIT have just made a big step towards a single-atom bit: They fixed a single atom on a surface such that the magnetic spin remained stable for 10 minutes.

Columbia engineers make world's smallest FM radio transmitter
A team of Columbia Engineering researchers, led by Mechanical Engineering Professor James Hone and Electrical Engineering Professor Kenneth Shepard, has taken advantage of graphene's special properties -- its mechanical strength and electrical conduction -- and created a nano-mechanical system that can create FM signals, in effect the world's smallest FM radio transmitter. The study is published online on Nov. 17, in Nature Nanotechnology.

Scientists invent self-healing battery electrode
Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices. The secret is a stretchy polymer that coats the electrode, binds it together and spontaneously heals tiny cracks that develop during battery operation, said the team from Stanford University and the Department of Energy's SLAC National Accelerator Laboratory.

Graphene nanoribbons for 'reading' DNA
One of the methods used for examining the molecules in a liquid consists in passing the fluid through a nano-sized hole so as to detect their passage. EPFL researchers have found a way to improve this technique by using a material with unique properties: graphene.

Quantum state world record smashed
A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers. The research, published in the journal Science, was led by Mike Thewalt (Simon Fraser University, Canada), with involvement from researchers at UCL and Oxford University, and material provided from collaborating institutes in Berlin.

Nanoparticles to probe mystery sperm defects behind infertility
A way of using nanoparticles to investigate the mechanisms underlying 'mystery' cases of infertility has been developed by scientists at Oxford University. The technique, published in Nanomedicine: Nanotechnology, Biology and Medicine, could eventually help researchers to discover the causes behind cases of unexplained infertility and develop treatments for affected couples. The method involves loading porous silica nanoparticle 'envelopes' with compounds to identify, diagnose or treat the causes of infertility.

UT Austin researchers grow large graphene crystals that have exceptional electrical properties
UT Austin researchers are using oxygen to grow large single graphene crystals on copper. Large single-crystal graphene is of great interest because the grain boundaries in polycrystalline material have defects, and eliminating such defects makes for a better material.

A nano-sized sponge made of electrons
During chemical reactions, ceria nanoparticles behave in a completely different way than previously thought: the electrons absorbed and released during the reaction are not bound to individual atoms but, like a cloud, distribute themselves over the whole nanoparticle. His has far-reaching consequences for optimising the current and future use of these nanoparticles and to assess the limits of their safe use.

Researchers at Penn add another tool in their directed assembly toolkit
An interdisciplinary team of University of Pennsylvania researchers has already developed a technique for controlling liquid crystals by means of physical templates and elastic energy, rather than the electromagnetic fields that manipulate them in televisions and computer monitors. They envision using this technique to direct the assembly of other materials, such as nanoparticles. Now, the Penn team has added another tool to this directed assembly toolkit.
