Haydale announces joining the BIOGRAPHY project for developing graphene-based sensors

Haydale, the UK based company focused on the commercialization of graphene and other nanomaterials, declared its partnership in BIOGRAPHY, an EU funded project (through M-ERA.Net). 

Haydale's proprietary HDPlas graphene-based conductive inks will be used to establish a cost-effective mass production process for graphene-based biosensors, which are predicted to have a major influence on developing healthcare and environmental applications.

Graphene-diamond combo to facilitate ultra-fast read head for quantum computers

A team of scientists from the TU Munchen, in collaboration with the Spanish Institut de Clencies Fotoniques, managed to devise a methodology for electronically reading optically writen information from quantum computers using graphene. Sensors built using this technology could be used not only to measure extremely fast processes, but also be integrated into future quantum computers and allow clock speeds ranging into the terahertz domain. 

This technique is based on a direct transfer of energy from nitrogen-vacancy centers in nanodiamonds (diamond defects comprising of a nitrogen atom and a vacancy) to a directly neighboring graphene layer. In contrast to the diamonds in which individual nitrogen-vacancy centers are insulated from each other, the graphene layer is electrically conducting. Two gold electrodes detect the induced charge, making it electronically measurable.

Graphene-enhanced quantum dots for medical and lighting uses

Reseachers from the University of Sydney managed to create graphene quatum dots that shine nearly five times brighter than regular dots. These powerful dots can be used for bio-imaging, like capturing images of internal organs or be injected into the body to detect cancer cells. They are even much less toxic compared to current dots for internal use. Other possible uses include ultra-bright LEDs, like the ones in screens or signs, or even batteries with long-life and faster charging times.

The researchers used ultrasound to break graphene sheets into atom-scale dots, then used potassium hydroxide to enhance the surface area of these dots. They increased the surface area by six times to get the dots to fluoresce almost five timer brighter than conventional dots.

Graphene-enhanced cycling helmets by Catlike

A Spanish sports equipment company called Catlike uses graphene to produce cycling helmets, in a line called Mixino 2014. The company states that graphene allows improving the helmet's safety features, as well as reaching minimum volume and weight and increase ventilation.

The Mixino helmet has a robust inner skeleton, made in the shape of an aramid skeleton (Aramid Roll Cage) which has been treated with graphene in its polymer matrix. This increases the entire mechanical performance and improves impact energy absorption.

The Mixino line includes several models, among them Mixino Road, Mixino MTB, Mixino VD2.0 and more.

HEAD launches Super Joy line of graphene-enhanced skis

International sports equipment company HEAD launches a line of skis that features graphene. Their new Joy line for women boasts several models of skis, enhanced with graphene. The company states that graphene enables them to reduce weight while increasing the product's strength.

Graphene will be used in the midsection of the groomer ski category to allow heavier tip and tail of the ski to grip the snow, and in powder boards graphene was used in the tip and tail to allow the ski to float through the fluff.
