Polish team creates transparent cryogenic temperature sensor

Jan 08, 2017

Researchers from the Lodz University of Technology in Poland have designed a transparent, flexible cryogenic temperature sensor with graphene structures as sensing elements. Such sensors could be useful for any field that requires operating in low-temperatures, such as medical diagnostics, space exploration and aviation, processing and storage of food and scientific research.

Making graphene transparent cryogenic temperature sensors

The sensors were repeatedly cooled from room temperature to cryogenic temperature. Graphene structures were characterized using Raman spectroscopy. The observation of the resistance changes as a function of temperature indicates the potential use of graphene in the construction of temperature sensors. The temperature characteristics of the analyzed graphene sensors exhibit no clear anomalies or strong non-linearity in the entire studied temperature range (as compared to the typical carbon sensor).

MIT team uses graphene to create ultra-strong 3D materials

Jan 08, 2017

Researchers at MIT have designed a strong and lightweight material, by compressing and fusing flakes of graphene. The new material, a sponge-like configuration with a density of just 5%, can have a strength 10 times that of steel. This work could pose an interesting way of transforming graphene into useful 3D objects and items.MIT created superstrong graphene 3D material image

The team developed the product by using a combination of both heat and pressure, compressing and fusing the flakes of graphene together. This process produced a strong, stable structure whose form resembles that of some corals and microscopic creatures called diatoms. These shapes, which have an enormous surface area in proportion to their volume, proved to be remarkably strong.

Versarien enters agreement with Fern Plastic Products to manufacture graphene-enhanced injection moulded products

Dec 20, 2016

Versarien announced an agreement with Fern Plastic Products to manufacture injection moulded products using graphene-enhanced polyaryletherketone (PAEK) materials. The agreement with Fern Plastics follows the agreement with Scafell Organics announced earlier this month.

The plan is for Versarien to utilize Fern Plastics' manufacturing facilities and expertise to produce injection moulded products using graphene-enhanced PAEK materials produced through Versarien's collaboration with Scafell.

UCF researchers receive $1.3 million from DARPA to develop a graphene-enhanced IR detector

Dec 18, 2016

The Defense Advanced Research Projects Agency (DARPA) has reportedly awarded a $1.3 million grant to a team from the University of Central Florida (UCF) to fund the development of a graphene-enhanced next-generation infrared detector that could be used in fields like night vision, meteorology, and space exploration.

The UCF team is working on an entirely new type of detector that relies on graphene. The researchers plan to use graphene to make an infrared detector that is small, portable, doesn't need to be cooled, and produces high-resolution images. Unlike current technologies, which can detect only one band of light, the next-gen detector would be tunable and able to see a range of bands.

Versarien enters agreement with Scalfell Organics to develop graphene-enhanced PAEK materials

Versarien logo imageVersarien, the advanced materials group, has signed an agreement with polymer chemical producer Scafell Organics to develop graphene-enhanced polyaryletherketone materials (PAEKs). These materials are a family of semi-crystalline thermoplastics with high-temperature stability and high mechanical strength, used in the automotive and aerospace industries.

Versarien reportedly plans to utilize Scafell’s facilities and production expertise to produce graphene enhanced PAEK materials using Versarien supplied graphene nano platelets. It is hoped that these graphene enhanced materials will be available for sale by Versarien through its sales team as well as Scafell’s customers.
