Recent Graphene news:
An international team of researchers from The University of Manchester, the University of Ulm in Germany and the University of Science and Technology of China created a transparent nanosized graphene capillary to investigate the atomic structure of water trapped inside.
The findings shed light on the unexpected behaviour of water at the molecular scale and are important for development of more efficient water treatment technologies including filtration, desalination and distillation.
The Spanish Graphenea, along with Russian and Spanish collaborators, have shown that adding graphene to alumina improves the ceramic's wear resistance and decreases friction. The result is expected to soon find uses in real products, as graphene and its derivatives seem to be biocompatible and in addition carry a low cost.
Alunima (an oxide of aluminium) has been long in use in biomedical applications such as load-bearing hip prostheses and dental implants, due to its high resistance to corrosion, low friction, high wear resistance and strength. This recent study describes the dry sliding behavior of a graphene/alumina composite material and compares it to regular alumina. The wear rate of the advanced composite was 50% lower than that of pure alumina, while the friction coefficient was reduced by 10%. This finding is made even more astonishing by the fact that the concentration of graphene in the final product is only 0.22% by weight. The type of graphene used for the study is Graphenea's standard graphene oxide.
U.S-based Local Motors plans to 3D print vehicles within 12 hours, reinforcing extruded printed material with graphene. The company reports significant progress in its additive manufacturing technology since it unveiled its Strati vehicle (pictured) last September.
The Strati's body was printed in 44 hours, assembled and driven at the International Manufacturing Technology Show in Chicago last year. It used ABS plastic reinforced with carbon fibre, and contained 40 printed parts. Local Motors announced plans in January this year to open two “microfactories” in the US, and plans 50 such factories worldwide over the next five years.
A team of scientists led by the Department of Energy's Oak Ridge National Laboratory (ORNL) demonstrated an energy-efficient desalination technology that makes use of a porous membrane made of free-standing, porous graphene.
The scientists report that the flux through these graphene membranes was at least an order of magnitude higher than the water that pass through state-of-the-art reverse osmosis polymeric membranes. Many of the current methods for purifying water require a significant amount of energy. Making the membrane more porous and thinner (properteis graphene is well suited to supply), helps increase the flux through the membrane and reduce the pressure requirements to reduce the amount of energy that the process requires.
Haydale announced a new 230 m2 dedicated manufacturing area at its South Wales, UK facility to keep up with rapidly growing demand for these ground breaking materials.
Haydale graphene inks are manufactured using plasma functionalised HDPlas® Graphene Nanoplatelets (GNPs) to deliver performance benefits including: metal-free, electrical conductivity, flexibility, and durability. Haydale graphene ink is formulated to be ready-to-use and can also be customized for individual applications. Their patented HDPlas® plasma process allows Haydale to use with a range of different raw graphene materials and to add the chemical functionalisation to meet desired performance for a wide range of specific applications.
Applied Graphene Materials announced their financial results for 2014. Pre-tax losses for the year ended in 31 January 2015 was £1.9 million, up from £1.2 million in the previous year. The increase is mostly due to AGM's increased invesetment in production, business infrastructure and new employees. AGM has about £6.6 million in cash as of the end of January 31.
AGM says that they are anticipating future growth and to support this new growth they had to increase expenses. The company remains confident of progress in 2015, and they see accelerated graphene sampling by customers. Production volume has been increased in past months. 90% of AGM’s ongoing engagements are with its three core target markets of advanced composites, coatings and functional fluids.
Scientists at the University of Illinois at Chicago engineered a humidity sensor on a bacterial spore. They call it NERD, for Nano-Electro-Robotic Device. They've taken a spore from a bacteria and put graphene quantum dots on its surface, then attached two electrodes on either side of the spore. Then they change the humidity around the spore,causing the spore to shrink. As it shrinks, the quantum dots come closer together, increasing their conductivity, as measured by the electrodes.
The researchers report a very sharp reaction once the humidity is changed, around 10 times faster than a sensor made with the most advanced man-made water-absorbing polymers. There was also better sensitivity in extreme low-pressure, low-humidity situations. The researchers also said it is possible to go all the way down to a vacuum and see a response, which is important in applications where humidity must be kept low,like preventing corrosion or food spoilage and space applications, where any change in humidity could signal a leak.
