Cardea Bio raises $7.5 million in series A2 financing

Following a $7.8 Million Series A-1 financing announced in March 2019, Cardea, (formerly called Nanomedical Diagnostics), a U.S-based manufacturer of a biology-enabled transistor technology made from graphene-based biosensors, now announced another $7.5 Million raised in the a Series A2 Financing.

The capital will help accelerate the growth and development of the Company’s proprietary Tech+Bio Infrastructure and chipsets that enable Cardea’s Innovation Partners to bring “Powered by Cardea" products to market with features and competitive advantages Cardea defines as "never seen before".

Researchers track the path of calcium atoms added to graphene

Researchers from Australia's Monash University, U.S Naval Research Laboratory, University of Maryland and IMDEA Nanociencia in Spain have confirmed what actually happens to calcium atoms that are added to graphene in order to create a superconductor: surprisingly, the calcium goes underneath both the upper graphene sheet and a lower ‘buffer’ sheet, ‘floating’ the graphene on a bed of calcium atoms.

Superconducting calcium-injected graphene holds great promise for energy-efficient electronics and transparent electronics.

Haydale signs collaboration agreements with Dowty Propellers

Haydale logoHaydale has announced the signing of contracts for the provision of services for the collaborative development of graphene and nano material enhanced products for use in Dowty Propellers’ products. Haydale will assist Dowty in examining the feasibility and development of various material technologies, pertinent to Dowty’s future product development, involving the incorporation of graphene and other nano materials.

Haydale will work with Dowty to develop erosion-resistant coatings with the addition of Haydale’s proprietary Silicone Carbide (SiC) Microfibers. Further development work is ongoing to establish the feasibility of potential industry-changing technology for the turboprop sector. In addition to these topics, Haydale will develop graphene-enhanced functional inks for strain sensing using its surface engineered HDPlas graphene nanomaterials.

What's new in graphene batteries? Highlights from summer 2020

The potential for improved performance and life cycle, fast charging and enhanced safety have proven to be enough of an incentive to inspire active study into graphene-based batteries, with many researchers and companies working globally to develop this energy Holy Grail.

Graphene battery advantages image

Graphene-enhanced batteries seem to be one of those technologies that holds great promise and appeal, but always remains somewhat unattainable. Some batteries have been commercialized in which graphene was used to perform secondary functions - such as to enhance the casing flexibility or the heat dissipation abilities. These batteries have been launched in some markets - but this is not the breakthrough everybody is waiting for. Some claims have been made regarding actual graphene batteries. Some of these have been found to be outright scams while others have yet to form an actual presence on the market. It is also important to know that not all graphene-enhanced batteries actually use graphene - some use graphene derivatives or multi-layer graphene which is actual graphite.

In spite of all the above, advances are being made and milestones achieved, with some initial products entering the market and great amounts of funds invested into R&D. It is still our view that graphene holds great promise for the batteries of the future.

GAC establishes graphene unit to develop fast-charging EV Tech

Chinese EV maker Guangzhou Automobile New Energy (GAC), which announced last May that it has developed a graphene-enhanced battery for EVs which will be available for mass production at the end of this year, recently set up a unit that specializes in graphene and has begun research and development of fast-charging technology for electric vehicles.

Guangzhou Juwan Technology Research has registered capital of CNY58.8 million (USD8.6 million), according to statements by the Guangzhou-based company. It specializes in new materials and technologies, graphene and carbon products manufacture, battery production, emerging energy tech R&D, software development and sales of graphene materials.

Graphene/hBN SQUID detects even the faintest magnetic fields

Researchers at the University of Basel in Switzerland, Budapest University of Technology and Economics in Hungary and National Institute for Material Science in Japan have developed a new, super-small device that is capable of detecting minute magnetic fields.

The device, a new kind of superconducting quantum interference device (SQUID), is just 10 nanometres high, or around a thousandth of the thickness of a human hair. It's made from two layers of graphene – making it one of the smallest SQUIDs ever built – separated by a very thin layer of boron nitride.
