ESC and Evercloak to collaborate on project to build pilot-scale commercial production of graphene-based membranes

Environmental Systems Corporation (ESC) and Evercloak have announced a new CAD$4.6 million (around USD$3.64 million) collaborative project to build up to pilot-scale commercial production of graphene-based membranes. The project will be funded by Next Generation Manufacturing Canada (NGen) from the Ministry of Innovation, Science, and Economic Development Canada.

"This is a very exciting time for us. This collaboration represents a crucial building block towards net-zero by the year 2030 by reducing energy processes for cleanrooms. We are very excited to work with Evercloak and NGen on this initiative," said Vern Solomon, Founder/ Innovator of ESC.

First commercial contract for water filtration membranes enhanced with graphene oxide

UK's G2O Water Technologies has reported securing its first commercial contract for the enhancement of water filtration membranes with graphene oxide.

The Company explains that the advantages of using graphene oxide lie in the enhancement of membrane performance, as it mitigates the effects of fouling – one of the biggest challenges operators of membrane-based water filtration systems face. With a coating of graphene oxide, successfully developed and piloted by the company in the northwest of England in collaboration with Hydrasyst Limited, operators can improve operational efficiency, reduce energy consumption and decrease chemical usage. It is anticipated that this will extend the lifetime of the membranes, as well as significantly reduce the cost and environmental impact of water treatment.

Ora Graphene announces a strategic investment to advance existing graphene endeavors and explore additional application areas

Ora Graphene, producer of free-standing graphene membranes, has announced the closing of its CAD$3 million (around USD$2.46 million) Seed financing round. The deal was led by Ecofuel Fund along with Export Development Canada (EDC), BDC Capital and certain members of New York Angels. Existing investors TandemLaunch, and BoxOne Ventures also participated in the round. In conjunction with the financing, the company was recently awarded a Sustainable Development Technology Canada grant to explore new areas of graphene applications for its technology.

Ora has produced what it refers to as 'the largest sheets of free-standing graphene demonstrating incredible new material properties for multi-purpose commercial utilization'. GrapheneQ™ membranes have already been shown to significantly improve sound quality and reduce energy consumption for global manufacturers of consumer electronics, with applications being developed for exciting new markets opportunities.

EPFL scientists develop highly efficient graphene-based carbon dioxide filter

Scientists at EPFL have developed an energy-efficient graphene-based carbon dioxide filter that can extract carbon dioxide out of a gas mix, to then be either stored or converted into useful chemicals.

Professor Kumar Varoon Agrawal at EPFL's School of Basic Sciences (EPFL Valais Wallis) has led a team of chemical engineers to develop the world's thinnest filter from graphene. "Our approach was simple," says Agrawal. "We made carbon dioxide-sized holes in graphene, which allowed carbon dioxide to flow through while blocking other gases such as nitrogen, which are larger than carbon dioxide." The result is a record-high carbon dioxide-capture performance.
