The remarkable properties and subsequent applications of graphene have been well-documented since it was first isolated in 2004; however, researchers are still trying to find a quick, cheap and efficient way of measuring its thickness. A group of researchers from China appear to have solved this problem by devising a universal method using just a standard optical microscope.

Gels that can be injected into the body, carrying drugs or cells that regenerate damaged tissue, hold promise for treating many types of disease, including cancer. MIT chemical engineers have now designed an injectable gel that responds to the body's high temperature by forming a reinforcing network that makes the gel much more durable, allowing it to function over a longer period of time.

Read moreFractal Antenna Systems today disclosed that it has successfully rendered a man invisible. The firm's new invisibility cloak hid a man at microwaves over a wide bandwidth at high fidelity. This is the first time any large object has been rendered invisible and the first time a person has disappeared from view using invisibility cloak technology.

Using tiny radiation pressure forces - generated each time light is reflected off a surface - University of Oregon physicists converted an optical field, or signal, from one color to another. Aided by a "dark mode", the conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.

To detect the toxicity of engineered nanomaterials, such as carbon nanotubes, on living cells, researchers have developed a "nanocanary", the modern-day, high-tech equivalent of the canary in a coal mine that warned miners of dangerous buildups of toxic gases in the mine shaft.

A novel push coating technique that uses an original silicone rubber stamp having a trilayer structure has been developed. The technique enables highly efficient use of materials, improvement in thin-film crystallinity, and high resolution patterning. The findings should considerably accelerate the research and development of flexible electronic devices.

Researchers from the University of Southern California and the National Institute of Standards and Technology have demonstrated a technique for growing virtually pure samples of single-wall carbon nanotubes with identical structures, a process they liken to "cloning" the nanotubes. If it can be suitably scaled up, their approach could solve an important materials problem in nanoelectronics: producing carbon nanotubes of a specific structure to order.
