Copper promises cheaper, sturdier fuel cells
Duke chemists are exploring the use of copper nanowires in fuel cells to convert solar energy into storable fuel. Copper nanowire catalysts cost less to produce than their indium tin oxide counterparts because they can be "printed" on pieces of glass or plastic in a liquid ink form, using a machine that functions much like a printing press. The nanowires can also be incorporated into transparent, flexible films.

'Wonder of Nanotechnology' details research enabling nanoscale optoelectronic devices
The inspiration of nature in studying nanoscale structures and the ability to control material composition on the nanometer scale are helping photonics engineers to create new devices and materials that transcend the properties of naturally occurring materials. A new book published by SPIE, the international society for optics and photonics, presents state-of-the-art research in the field.

What can happen when graphene meets a semiconductor
A UWM study has found that intrinsic ripples form on a sheet of graphene when it is placed on top of a semiconductor. The ripples further change the Schottky barrier height, affecting electron transport.

Infrared vision lets researchers see through -- and into -- multiple layers of graphene
A University at Buffalo-led research team has developed a technique for "seeing through" a stack of graphene sheets to identify and describe the electronic properties of each individual sheet -- even when the sheets are covering each other up.

Ultrasound, nanoparticles may help diabetics avoid the needle
A new nanotechnology-based technique for regulating blood sugar in diabetics may give patients the ability to release insulin painlessly using a small ultrasound device, allowing them to go days between injections -- rather than using needles to give themselves multiple insulin injections each day.

Scientists create perfect solution to iron out kinks in surfaces
A new technique that allows curved surfaces to appear flat to electromagnetic waves has been developed by scientists at Queen Mary University of London. The discovery could hail a step-change in how antennas are tailored to each platform, which could be useful to a number of industries that rely on high performance antennas for reliable and efficient wireless communications.

BU, MIT team engineers add new wrinkles to waterproofing
Intuition tells us that a smooth surface should shed water faster than a textured one. But a team of engineers from Boston University and the Massachusetts Institute of Technology have engineered a wrinkled surface that sheds liquid much faster than a smooth one, an innovation that has implications for a wide variety of materials that work better when dry.

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.

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.

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.
