Graphene exists in the free state

Scientists have attempted to prove that a 2D gauze of carbon atoms, called graphene, can exist in the free state. The material has potential for use in the manufacturing of micromechanical switches and electronic transistors, and more immediately as a substrate to aid transmission electron microscopy.

Non-reflective coating for optical devices

A material that has almost the same refractive index of air has been created, by positioning low-reflective silica nanorods onto a thin film of aluminium nitrate. The result is an innovative coating that reflects virtually no light allowing researchers to potentially reduce the negative effect on the performance of optical components and devices.
Living Brick

Living Brick

The Living Brick is a new construction material for facing urban/suburban structures. It exploits one of the most common commodities in the urban landscape – the surfaces of buildings – as spaces for ‘vertical gardens’. Extruded bricks can be used to create a garden wall or even to cover the facades of buildings.
PET brick

PET brick

Making use of discarded PET bottles, a professor and four engineering students from the Lutheran University of Brazil (Ulbra) have created a ‘PET brick’ made out of quartz sand, cement and bottles.

Nanosight microscope indentifies nanoscale cracks

NanoSight Ltd, UK, has developed a method for accurately visualising individual nanoparticles for nanoscale cracks and deformities. The NanoSight LM20 uses a conventional optical microscope fitted with a specialised camera and dedicated analytical software that makes use of a technique called nanoparticle tracking analysis (NTA).
