Indium Tin Oxide Might Be the Material Photonics Has Been Waiting For

There are plenty of reasons why it’s useful to transfer information through photons or use light particles to carry out tasks within a system or device, speed chief among them. But in order to use photons with even greater dexterity in the future, researchers will need to control the way light behaves as it passes through a material.

Now a team led by Robert Boyd, a physicist at the University of Ottawa and the University of Rochester, has found that a transparent metal called indium tin oxide (ITO), which is often used in touchscreens and on airplane windows, can achieve a particularly high degree of optical nonlinearity—making it a good candidate for future photonics applications.

Piezoelectric Graphene Ink Enables Thin-Film Pressure Sensors of Any Size

UK-based Haydale Graphene Industries Plc has established itself over the years as one of the go-to companies if you wanted graphene to have just the right properties for the device you were aiming to develop. If you wanted the graphene to have high conductivity, or maybe conductivity was not as critical as its thermal properties, Haydale was the place you would go to get graphene that did exactly what you wanted.

Metallic Mesh Becomes Invisible to Antenna Signals

Most of modern science’s attempts to recreate the invisibility cloaks found in TV’s Star Trek and the wizarding world of Harry Potter have focused on bending light waves around the object meant to be hidden. A team of U.S. and Chinese researchers have taken a very different direction by creating the first practical “invisible” material that allows certain electromagnetic signals to pass unimpeded as they would through air.
