In May 2017 we reported on a new project at the Institute of Low Temperature and Structure Research (Wroclaw, Poland) that developed a new efficient white light source that uses graphene foam excitated by a continuous-wave laser.
The project is still in progress, and the researchers demonstrated the technology at IDTechEx Graphene & 2D Materials Europe 2019 earlier this month, as can be seen in our video above.
China-based Wuxi Graphene Film (owned by Grahope New Materials and The Sixth Element) produces patterned CVD graphene films for heating applications. These films are adopted by several Chinese device makers for different heating products - for example Grahope's graphene eye mask we recently reviewed at Graphene-Info.
The team at Wuxi Graphene Film was kind enough to send a few such films for us to review. These specific films are designed for one of WGF's customers and include a proprietary design which includes a USB connector for easy setup - you just plug these into a USB power source and the films heat up very quickly.
Graphene Composites, a UK-based company developing graphene-enhanced bulletproof shields, has exceeded its crowdfunding target. GC attempted to raise £300,000 on Crowdcube, but ended up raising £510,680 (around 676,625 USD).
Once Graphene Composites had hit its crowdfunding target, the company sent out a message to its supporters saying: “Thank You - by investing in GC, you have not only invested in a company that should provide you with a healthy return and strong dividends, you are also enabling us to develop and deliver products that will truly improve the quality of life for many around the world. For example, our GC Shield active shooter protection in schools now, and eventually our Lightning Harvester renewable energy sources. Thank You, from all of us on the GC Team”.
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.
Ionic Industries has developed a number of prototype supercapacitor devices using its graphene technologies, and following is a video of one of these devices in operation.
Ionic states that these graphene-enhanced supercapacitors are inexpensive, safe and environmentally friendly and have the potential to power a broad range of Internet-of-Things devices (which are the markets that Ionic will be focusing on in the near term).
