Chinese researchers achieve photo-induced ultrafast active ion transport through graphene oxide membranes
Researchers from the Chinese Tsinghua University and CAS demonstrated a coupled photon-electron-ion transport phenomenon through graphene oxide membranes. Using the energy of light, cations are able to move thermodynamically uphill over a broad range of concentrations, at rates orders of magnitude faster than that via simple diffusion.
Based on this mechanism, the team further developed photonic ion switches, photonic ion diodes, and photonic ion transistors as the fundamental elements for active ion sieving and artificial photosynthesis on synthetic nanofluidic circuits.
Urbix Resources to build a purification plant in Vietnam
Aiming to ramp up their international operations, Urbix Resources will reportedly work with Hanoi-based Vietnam Graphite Group to build a 70,000 tonne purification plant in Vietnam. The Vietnamese purification plant will be situated within VGG’s graphite mining operations in North Western Vietnam and will serve customers in Japan and the surrounding region.
The facility is scheduled for stage one completion in late 2020. It is anticipated the purification plant will have the capability of achieving revenues exceeding US $200 million annually once the second stage is completed the following year. It appears that the plant will be used to produce, among other materials, graphene oxide and graphene nanoplatelets.
University of Manchester researcher develops GO coating that makes living cells and tissues more visible
University of Manchester researcher, Dr Thomas Waigh, has developed a technology that may make living cells and tissues more visible during analysis through the addition of graphene oxide (GO). The use of a GO GO coating to microscopy slides was found to improve both fluorescence imaging contrast and resolution.
Dr Waigh said: My team has developed technology which uses monomolecular sheets of GO to coat microscopy slides, thereby eliminating background fluorescence and improving the resolution of images. "It’s an important breakthrough as GO is cheap and easy to manufacture in large quantities. The cost to coat each slide is estimated to be 12 pence".
Northwestern team creates ‘GO dough’ for easy molding and transporting
Researchers from Northwestern University have turned graphene oxide (GO) into a soft, moldable and kneadable "play dough" that can be shaped and reshaped into free-standing, three-dimensional structures.
Called GO dough, this malleable material is said to solve several long-standing problems in the graphene manufacturing industry. Currently graphene oxide is stored as dry solids or powders, which are prone to combustion and explosion, said Jiaxing Huang, who led the study. Or they have to be turned into dilute dispersions, which multiply the material’s mass by hundreds or thousands.
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.
Rensselaer team develops a microfluidics-assisted technique to produce macroscopic graphene fibers
Researchers at Rensselaer Polytechnic Institute have developed a new microfluidics-assisted technique for developing high-performance macroscopic graphene fibers. Graphene fiber have potential applications in diverse technological areas, from energy storage, electronics, optics, electro-magnetics, and thermal conductors, to structural applications.
Sheet alignment and orientation order of graphene structures induced by microfluidics design enable the microstructure control and optimization of thermal-mechanical and electronic properties of macroscopic graphene fibers
The team explained that It has been historically difficult to simultaneously optimize both the thermal/electrical and the mechanical properties of graphene fibers. However, the Rensselaer team has demonstrated their ability to do both.

Graphene-Info's introduction to reduced graphene oxide
Today we published a new article, an introduction to reduced graphene oxide. Our article discusses the material properties, rGO production and potential application.
Garmor creates extra strong polymeric coatings and innovative conductive fibers
Garmor, manufacturer of low-cost graphene oxide, rGO and developer of innovative GO production methods, recently developed a graphene-enhanced polymeric coating with a 390% reported improvement in tensile strength. Garmor stated that it is already marketing this technology as it has already been fielded and used in commercial applications. Here's a video showing side-by-side testing of the original polymer (left) and the graphene-enhanced polymer (right) shown at 4X normal speed.
In addition, Garmor announced the development of an innovative process for converting insulating polymeric fibers into electrically conductive fibers with minimal cost and no waste products. The method has resulted in composites with single-digit graphene loadings delivering conductivity as high as .023 S/cm. Garmor sees such performance as ideal for wearable sensors and other applications that require integrated approaches to solving weight and measurement issues.
