Versarien has shared that trials of a precast concrete containing its Cementene water-based graphene mixture were shown to maintain its strength with 20% of the cement removed.

The initial results, carried out in tests at the accredited laboratory of Ireland-based Banagher Precast Concrete, “demonstrate the significant potential to reduce CO₂ emissions without impacting the performance of the concrete”, the AIM-listed company said. This is because producing 1kg of ordinary Portland cement emits around 0.8-0.9kg of CO₂ and roughly 500kg of cement is used per cubic metre of Banagher's precast concrete. Producing 1kg of Cementene is estimated to generate a higher level of CO₂ emissions, at 1.44 kg, but Versarien said because only around 5kg of Cementene is used per cubic metre of concrete and allows the removal of 20% of cement in the precast concrete mix, this would equate to a net saving of almost 73kg of CO₂ emissions per cubic metre of concrete poured.

Ionic Industries has announced the signing of an agreement for the sale of its first product developed from the Company's portfolio of graphene technologies. Ionic Industries referred to the patented conductive coatings applied to geotextiles as 'one of the world’s first large-scale applications of graphene technologies'. 

The supply agreement with GeoFabrics Australasia is for the supply of conductive, coated geotextile for sale by GeoFabrics as their Bidim-C product. The Bidim-C product is used to detect holes and potential leaks in newly constructed dams and water tank projects.  The agreement is for the supply of Bidim-C over the next 12 months and will generate up to AUD$1,000,000 (over USD$664,000) in revenue for Ionic.

Directa Plus announced that revenues in 2022 were €10.9 million, up 27% from 2021 (€8.6 million). It's pre-tax loss actually rose to €5.3 million from €3.4 million in 2021.

Researchers from Gwangju Institute of Science and Technology (GIST) and Chonnam National University Medical School have developed graphene-based conductive hydrogel electrodes that offer convenience of use, controllable degradation, and excellent signal transmission. 

Implantable bioelectrodes are electronic devices that can monitor or stimulate biological activity by transmitting signals to and from living biological systems. Such devices can be fabricated using various materials and techniques. But, because of their intimate contact and interactions with living tissues, selection of the right material for performance and biocompatibility is crucial. Conductible hydrogels are attracting great attention as bioelectrode materials owing to their flexibility, compatibility, and excellent interaction ability. However, the absence of injectability and degradability in conventional conductive hydrogels limits their convenience of use and performance in biological systems. The researchers' new graphene-based conductive hydrogels possess injectability and tunable degradability, furthering the design and development of advanced bioelectrodes.

Graphene-Info is happy to give the stage to talented young graphene researchers, especially with such commitment and passion as Roberto Pezone from TU Delft, who has agreed to chat with us and answer a few questions about his background, work and collaboration with the Graphene Flagship.

Roberto Pezone checking a wafer at its initial fabrication stages

Q: Thank you for this interview Roberto! Very nice to e-meet you. We know you have been involved with graphene research for some time, can you give us a quick overview of your graphene research interests and projects?

Thank you for the opportunity to discuss my research. Within the Graphene Flagship's Work Package 6 (core 3), my primary focus lies in integrating graphene into sensors, particularly microphones. My main objective is to develop methods that enable the seamless integration of graphene on a wafer-scale while thoroughly exploring the advantages and disadvantages associated with such approaches.

In addition to developing fabrication techniques, I am also highly interested in characterizing the potential of graphene for acoustic devices. This type of research plays a crucial role in bridging the gap between graphene's exceptional properties and its practical utilization in the industry, unlocking higher performance and new sensor concepts.

Researchers from Germany's RWTH Aachen University, Forschungszentrum Jülich and Japan's National Institute for Materials Science (NIMS) have found that bilayer graphene allows the realization of electron–hole double quantum dots that exhibit near-perfect particle–hole symmetry. Moreover, They showed that particle–hole symmetric spin and valley textures lead to a protected single-particle spin-valley blockade that will allow robust spin-to-charge and valley-to-charge conversion, which are essential for the operation of spin and valley qubits.

Quantum dots in semiconductors such as silicon or gallium arsenide are considered great candidates for hosting quantum bits in future quantum processors. The recent study essentially shows that bilayer graphene has even more to offer than other materials. The double quantum dots the researchers have created are characterized by a nearly perfect electron-hole-symmetry that allows a robust read-out mechanism – one of the necessary criteria for quantum computing.
