Graphene-Info: the graphene experts

University at Buffalo (UB) researchers have developed a novel 3D printed water-purifying graphene aerogel that could be scaled for use at large wastewater treatment plants.

Composed of aerogel graphene and two bio-inspired polymers, the novel material is reportedly capable of removing dyes, metals and organic solvents from drinking water with 100% efficiency. Unlike similar nanosheets, the scientists’ design is reusable, doesn’t leave residue and can be 3D printed into larger sizes. The team now plans to commercialize its design for industrial-scale deployment.

Battery materials startup Volexion has secured $1.1 million in funding as it moves toward commercialization of its graphene coating for lithium-ion cathodes. The U.S-based company aims to increase its output to “several kilogram” batch capacity after the funding as it works towards its goal of being commercially ready by 2024.

The closing of the first tranche of its $2.2 million seed financing was led by leading climate tech venture capital firms Clean Energy Ventures and Energy Foundry.

Graphene producer NanoXplore and its partner, Martinrea International, have announced a joint venture, VoltaXplore Inc., formed to develop electric vehicle (EV) batteries enhanced with graphene.

A VoltaXplore demonstration facility is scheduled to be opened in Montreal, Canada, within the next year for the development and production of EV batteries enhanced with graphene. The Companies stated that a successful demonstration of improved battery performance using graphene, along with positive feedback from customers, will support the business case for the construction of a battery production facility in Canada.

A team of researchers from Bielefeld and Berlin, together with researchers from other research institutes in Germany and Spain, recently demonstrated that graphene's nonlinearity can be efficiently controlled by applying comparatively modest electrical voltages to the material.

It was recently discovered that the high electronic conductivity and "massless" behavior of graphene's electrons allows it to alter the frequency components of electric currents that pass through it. This property is highly dependent on how strong this current is. In modern electronics, such a nonlinearity comprises one of the most basic functionalities for switching and processing of electrical signals. What makes graphene unique is that its nonlinearity is by far the strongest of all electronic materials. Moreover, it works very well for exceptionally high electronic frequencies, extending into the technologically important terahertz (THz) range where most conventional electronic materials fail.

The famous fashion brand Hermès has recently launched its new H08 Collection of watches, said to be the "sportiest timepiece series to date", which includes a graphene-enhanced model.

The H08 collection consists of three models, each differing in their case materials and strap options, but otherwise featuring the same overall design. The darkest of the group features a graphene-enhanced composite case with a satin-brushed ceramic bezel.

G6 Materials has announced that it has closed its non-brokered equity financing previously announced on March 2021. The Company reported that unit offering increased due to "strong investor demand" - from the CAD$5 million initial target, to the final closing of CAD$5.4 Million (around USD$4.29 million).

“The closing of this Offering is a significant milestone for G6 Materials as it not only funds our Company for future growth, but it also empowers us to complete the previously announced acquisition of GX Technologies,” said Daniel Stolyarov, President & CEO of G6 Materials Corp.

ZEN Graphene Solutions has announced that it completed its previously announced non-brokered private placement for aggregate gross proceeds of CAD$4,337,998 (around USD$3.46 million).

ZEN intends to use the net proceeds to fund capital expenditures and operating expenses at Guelph locations supporting the scale-up and production of its antimicrobial coating to serve existing client orders and create capacity for subsequent clients. ZEN also intends to continue to invest in its intellectual property related to graphene. Funds will also be used for general corporate purposes.
