Researchers at the University of Wisconsin-Milwaukee will be presenting a graphene-based sensing platform for real-time, low-cost detection of various water contaminants at the AVS's 64th International Symposium & Exhibition, being held Oct. 29-Nov. 3, 2017, in Tampa, Florida. The new sensor detects heavy metals, bacteria, nitrates and phosphates.

The sensor works by placing graphene-based nanosheets that are semiconducting between an electrode gap. The electrical conductivity of the graphene material changes with the binding of substances, called analytes, to its surface and their chemical constituents are identified and measured. "The magnitude of the conductivity change can be correlated to the concentration of analyte, and the technology also involves the functionalization of the graphene material surface with specific probes that can target a specific analyte," said the researchers.

Graphene Flagship partners Istituto Italiano di Tecnologia, Italy, in collaboration with FADEL, a leading Italian shoe company, have developed graphene-enhanced shoes. The new GET technology, patented by FADEL, reportedly gives the footwear better thermoregulation and freshness.

In this innovative shoe, when flakes consisting of several graphene layers are added to polyurethane, (the material of which the soles of FADEL shoes are made), laboratory tests show an augmented heat dispersion, a greater resistivity to water and enhanced antibacterial properties. Combining these effects with a ventilation system developed for this particular type of shoe yielded a better user experience. This prototype shoe was presented at the International Footwear Exhibition in Milan.

Graphene-Info's graphene catalog is probably the world's most complete online graphene materials catalog, and today we are happy to announce we have added graphene inks as a new material type.

Currently we list four different graphene inks, from three different producers. We aim to keep adding new materials to our catalog as the range of materials offered from graphene makers increase. If you seek to acquire graphene inks, all you have to do is click here and get started. We can also help with finding a graphene developer to produce custom graphene materials.

U.S-based Urbix Resources has unveiled new high-density, low leakage graphene-based supercapacitors. According to Urbix, these supercapacitors have energy density of >75 wH/L with volumetric discharge energy density that is five times larger than average, with the lowest leakage rate in market (days) and operational temperatures that go from -40° C to 70°C.

The supercapacitors can be customized to meet customer specifications, and can be included in other proprietary Urbix Energy Storage Systems upon request. According to Urbix, the products come in 3 form factors: 2032 (with capacitance of 2.5F), 2430 (4F capacitance) and custom (with custom capacitance).
