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.

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.

A team of researchers from the University of Basel, the National Institute for Material Science in Tsukuba in Japan, Kanazawa University, Kwansei Gakuin University in Japan and Aalto University in Finland has succeeded in using atomic force microscopy to obtain images of individual impurity atoms in graphene ribbons. Thanks to the forces measured in the graphene's two-dimensional carbon lattice, they were able to identify boron and nitrogen for the first time.

Using the atomic force microscope's carbon monoxide functionalized tip (red/silver), the forces between the tip and the various atoms in the graphene ribbon can be measured

The team replaced particular carbon atoms in the hexagonal lattice with boron and nitrogen atoms using surface chemistry, by placing suitable organic precursor compounds on a gold surface. Under heat exposure up to 400°C, tiny graphene ribbons formed on the gold surface from the precursors, including impurity atoms at specific sites.

Researchers from the Institute of Advanced Study in Science and Technology (IASST) in India have developed a smart bandage material based on graphene oxide that can heal wounds better and faster and has antimicrobial properties.

The bandage is made of cotton patch coated with chitosan-based hydogel that is loaded with curcumin and graphene oxide. The researchers used curcumin as a model drug but said it can be replaced with other antimicrobials.

In June 2016, LWP Technologies announced that it had entered into a 50/50 Joint Venture of patent pending Aluminium-Graphene Synthesis and battery technology with Russian scientist Viktor Volkov, representing VVV Technologies. The two companies announced they will setup a company called Graphenera and LWP raised $1.2 million to invest in Graphenera.

LWP shareholders reached out to us with a sad update to this story, which we detail below. We post this story as-is, as we cannot confirm all details below.

In January 2018 we posted a short hands-on review of Wuxi Graphene Film's GF1 Graphene Watch, a smart health watch, with CVD graphene film acting as the conductive element for the touch screen.

The GF1 has been shipping in China since late 2017, and the watch has finally reached the US via Amazon.com, where it can be bought for $55 (note: affiliated link to Amazon).
