Northwestern team creates ‘GO dough’ for easy molding and transporting

Researchers from Northwestern University have turned graphene oxide (GO) into a soft, moldable and kneadable "play dough" that can be shaped and reshaped into free-standing, three-dimensional structures.

Called “GO dough”, this malleable material is said to solve several long-standing problems in the graphene manufacturing industry. “Currently graphene oxide is stored as dry solids or powders, which are prone to combustion and explosion,” said Jiaxing Huang, who led the study. “Or they have to be turned into dilute dispersions, which multiply the material’s mass by hundreds or thousands.”

Haydale signs supply agreement for piezoresistive inks

Haydale logoHaydale has announced that it has signed a supply agreement to provide 76kg of its propriety piezoresistive ink to HP1 Technologies (HP1T) over an 18-month period. The value of the Supply Agreement was not disclosed.

HP1T creates bespoke flexible, printed, functionalized nano carbon-based sensor systems that can measure and collect high quality impact and pressure data. This newly signed supply agreement will see Haydale become HP1T's single supplier of functionalized nano carbon inks.

The Graphene Flagship moves towards new stage

The Graphene Flagship was launched in 2013 with the mission to take graphene and related layered materials from academic laboratories to the market, revolutionize multiple industries and create economic growth and new jobs in Europe. Five years later, the Flagship consortium has reported that it successfully completed the Core1 phase and is progressing towards more applied phases. It is reportedly on its way to achieving its objective of developing the high potential of graphene and related 2D materials to the point of having a dramatic impact on multiple industries.

The Reviewing Panel thoroughly examined the results obtained in this Core1 phase and concluded that for many topics, there has been a clear transformation of the activities, moving from individual research projects to genuine collaboration towards larger goals – exactly what a Flagship project should aim for. Nearly all milestones and key performance indicators have been met, often exceeding expectations. There are numerous examples of significant scientific and/or technological achievements, with clear progress beyond the state of the art. The Work package on Photonics and Optoelectronics led by ICREA Prof. at ICFO Frank Koppens was recognized as one of the closest to being brought into industrial exploitation due to its significant potential for both scientific breakthrough and innovation.

Graphene Flagship team creates photosensitive graphene-based "switches"

Partners of the European Project 'Graphene Flagship' at the University of Strasbourg and CNRS (France), along with an international team of collaborators, created new 'switches' that respond to light. The team combined light-sensitive molecules with layers of graphene and other 2D materials to create new devices that could be used in sensors, optoelectronics and flexible devices.

The researchers designed a molecule that can reversibly undergo chemical transformations when illuminated with ultraviolet and visible light. This molecule (a photoswitchable spiropyran) can be then attached to the surface of materials like graphene or molybdenum disulfide, thus generating an atomically precise hybrid macroscopic superlattice. When illuminated, the whole supramolecular structure experiences a collective structural rearrangement, which could be directly visualized with a sub-nanometer resolution by scanning tunneling microscopy.
