Haydale announced inking a deal to supply the Centre for Process and Innovation (CPI) in the UK with its HT60 reactor, which is expected to be fully operational by October 2015. The deal will produce an initial revenue of â‚¤170,000 for Haydale. Haydale successfully tendered for the supply agreement and will deliver a standard HT60 R&D reactor later this month and then provide training and technical support to CPI. Following this deal, Haydale is looking to concentrate on its commercialization strategy over the next year, with the U.S market a key area of growth.

CPI is a UK-based technology innovation centre and part of the High Value Manufacturing Catapult. CPI has recently committed £14 million to create the UK’s Graphene Applications Innovation Centre. The new centre will build on existing capabilities at CPI and will provide facilities and expertise to help companies to develop, prove, prototype and scale up graphene based products and processes.

Researchers at Rice University, the Indian Institute of Technology and the Lebanese American University discovered that grinding carbon nanotubes might be a simple way of forming graphene nanoribbons. The research indicates that a simple process like grinding could deliver strong chemical coupling between solid nanostructures and produce novel forms of products with specific properties.

The scientists mixed two types of chemically modified nanotubes (one with carboxyl groups and the other with hydroxyl groups attached) and ground them together for about 20 minutes using a mortar and pestle. They noticed that when the two types of nanotubes come into contact during grinding, they react and unzip, a process that until now has depended largely on reactions in specific chemical solutions.

Researchers at the Lawrence Livermore National Laboratory created graphene aerogel microlattices with an engineered architecture using a 3D printing technique known as direct ink writing. These lightweight aerogels have high surface area, excellent electrical conductivity, mechanical stiffness and exhibit supercompressibility (up to 90% compressive strain). In addition, the researchers claim that these 3D printed graphene aerogel microlattices show great improvement over bulk graphene materials and much better mass transport.

A common problem in creating bulk graphene aerogels is the occurrence of a largely random pore structure, thus excluding the ability to tailor transport and additional mechanical properties of the material for specific applications such as batteries and sensors. Making graphene aerogels with engineered architectures is greatly assisted by 3D printing, which allows to design the pore structure of the aerogel, permitting control over many properties. This development, as per the scientists, could open up the design space for using aerogels in novel and creative applications.
