CPI, Haydale and others collaborate on Smart Filter project

The Centre for Process Innovation (CPI) has collaborated on a project to advance the development of a low-cost, self-cleaning coating technology for industrial filter membranes.

The Smart Filter project used graphene and its derivatives to create a coated filter membrane that offers increased resistance to fouling for industrial waste water treatment. Membrane filters are used in a number of industrial separation applications but are afflicted by fouling, which typically lowers throughput or increases energy consumption, and reduces filter life. Focusing upon oil water separation and nuclear waste water treatment, the collaboration, with G2O Water Technologies, Haydale and Sellafield, developed a repeatable, reproducible and scalable process to make coated filter membranes, which delivered a 30% improvement in permeability when compared to an equivalent uncoated filter.

Researchers use bacteria to create a graphene oxide based water filter that kills bacteria

Researchers from Washington University have designed a novel membrane technology that purifies water while preventing biofouling, or buildup of bacteria and other harmful microorganisms that reduce the flow of water. And they used graphene and bacteria to build these filtering membranes.

The team developed an ultrafiltration membrane using graphene oxide and bacterial nanocellulose that they found to be highly efficient, long-lasting and environmentally friendly. If their technique were to be scaled up to a large size, it could benefit many developing countries where clean water is scarce.

G2O secures £1 million investment

water technology company G2O recently announced a £1.035 million investment in a round led by private equity firm Maven Capital Partners, and plans to sign collaborative partnerships with suppliers and enter global markets to expand customer reach.

Maven Capital Partners, one of the UK’s most active private equity firms, has led a £1.035 million investment in Manchester-headquartered water treatment technology business. A total of £600,000 has been provided by Maven funds, which includes a £400,000 investment from NPIF – Maven Equity Finance, which is part of the Northern Powerhouse Investment Fund and a £200,000 investment from the Finance Durham Fund, both managed by Maven. The additional £435,000 is from a number of private individual investors.

NIST team finds that graphene can stretch to be a tunable ion filter

Researchers at the National Institute of Standards and Technology (NIST) have conducted simulations suggesting that graphene can be modified with special pores to act as a tunable filter or strainer for ions in a liquid.

The concept could have applications like nanoscale mechanical sensors, drug delivery, water purification and sieves or pumps for ion mixtures similar to biological ion channels, which are critical to the function of living cells.

Graphene to enable next-gen reflective-type displays that operate faster and at much higher resolution than currently possible

A joint collaboration of researchers from SCALE Nanotech, Graphenea and TU Delft have used graphene to make reflective-type displays that operate faster and at much higher resolution than existing technologies.

Displays consume the most power in electronic gadgets. Portable devices like smartphones and VR visors therefore require most of the energy from batteries. As an alternative solution, reflective-type displays (like those in e-book readers) consume much less power, though they cannot deliver video. Reflective displays that offer the specifications of standard technologies (OLED, LCD) do not exist yet, but graphene may open the door to such possibilities.
