Surwon Technology to sign filtration products deal

Hong Kong-based advanced materials company Surwon Technology announced that a version of a new membrane coating it has tested in heavy-duty desalination applications could soon be part of new water filtration products specially-developed for the consumer market.

The ultra-thin, graphene-based coating has reportedly continued to perform well in ongoing controlled tests at various desalination plants on the Chinese mainland and the company says it is convinced the technology can make a substantial contribution to reducing the cost of thermal and reverse osmosis systems.

Spanish scientists open the door to using graphene in smart filters and sensors

As part of a national research collaboration, Spanish researchers including the ICN2 have reached a milestone in graphene research, that potentially brings science a step closer to using graphene in filtration and sensing applications.

The researchers have successfully synthesized a graphene membrane with pores whose size, shape and density can be tuned with atomic precision at the nanoscale. Engineering pores at the nanoscale in graphene can change its fundamental properties. It becomes permeable or sieve-like, and this change alone, combined with graphene's intrinsic strength and small dimensions, points to its future use as the most resilient, energy-efficient and selective filter for extremely small substances including greenhouse gases, salts and biomolecules.

EU project to develop graphene-based products for protection of artwork

An interesting project under the H2020 initiative is GRAPHENART - focused on examining graphene as an anti-fading agent for the protection of artworks. The project, funded at about €150,000, started at October 2017 and will go on until March 2019.

The reasoning behind the project is that fading, yellowing and discoloration are common degradation effects that result from exposure to UV and visible light and oxidizing agents, resulting in the irreversible alteration of the appearance of contemporary artworks. The GRAPHENART project aims to develop innovative, multi-functional graphene-based products (graphene ‘veils’ and inclusions) that provide UV shielding, de-acidification, oxygen and humidity barriers for the protection of old and modern paintings and artworks.

Australian team develops new GO-based filter that can improve drinking water quality

Researchers at UNSW have developed a graphene-based, laboratory-scale filter that can remove more than 99% of the natural organic matter left behind during conventional treatment of drinking water. In a research collaboration with Sydney Water, the team has demonstrated the success of the approach in laboratory tests on filtered water from the Nepean Water Filtration Plant in western Sydney, and is working to scale up the new technology.

Australian team develops promising GO membranes for water treatment image

"Our advance is to use filters based on graphene – an extremely thin form of carbon. No other filtration method has come close to removing 99% of natural organic matter from water at low pressure," the UNSW team said. "Our results indicate that graphene-based membranes could be converted into an alternative new option that could in the future be retrofitted in conventional water treatment plants."

A project for the development of a GO-based membrane secures $2.9 million funding from DoE

The Department of Energy (DoE) has selected six projects that seek to make carbon capture technology more affordable and reliable for use in coal-fired power plants to receive $17.3 million in federal funding. Among the project is one graphene project.

The Institute of Gas and Technology has been awarded $2.9 million to develop a transformational graphene oxide-based membrane process for post-combustion carbon capture. The project has also secured $750,052 in non-federal funding.
