Ora Graphene announces a strategic investment to advance existing graphene endeavors and explore additional application areas

Ora Graphene, producer of free-standing graphene membranes, has announced the closing of its CAD$3 million (around USD$2.46 million) Seed financing round. The deal was led by Ecofuel Fund along with Export Development Canada (EDC), BDC Capital and certain members of New York Angels. Existing investors TandemLaunch, and BoxOne Ventures also participated in the round. In conjunction with the financing, the company was recently awarded a Sustainable Development Technology Canada grant to explore new areas of graphene applications for its technology.

Ora has produced what it refers to as 'the largest sheets of free-standing graphene demonstrating incredible new material properties for multi-purpose commercial utilization'. GrapheneQ™ membranes have already been shown to significantly improve sound quality and reduce energy consumption for global manufacturers of consumer electronics, with applications being developed for exciting new markets opportunities.

An interview with GraphAudio's CEO to discuss the company's CVD graphene-based speaker technology

GraphAudio was established in 2016 to commercialize graphene-based acoustic products based on technology that originated from UC Berkeley and Berkeley Lab. GraphAudio's technology enables electrostatic micro transducers that use CVD graphene sheets.

GraphAudio's CEO is Ramesh G. Ramchandani, that previously held executive leadership positions at International Rectifier, Semicoa, nPlay Technologies, ZiLOG and ON Semiconductor, and was a senior advisor for consumer and commercial AI at Google X. Following is an interview with Ramesh to discuss GraphAudio's technology, business and roadmap.

Penn State team applies 'magic angle' graphene to acoustics

A team of Penn State researchers has designed an acoustic equivalent of magic-angle bilayer graphene. Two graphene sheets stacked on top of each other, called bilayer graphene, exhibit unique properties when one of the layers is twisted at a certain angle — a “magic” angle. The study of magic and other angle misalignments between two layers of material and their effects on material properties has been dubbed twistronics, a rapidly expanding field of condensed matter physics.

“Examining analogues of condensed matter physics concepts can give us new ideas and applications in acoustics,” said Yun Jing, associate professor of acoustics and biomedical engineering.

New graphene-enhanced products raise old questions

When speaking of graphene in terms of commercialization, the general impression is that "a killer application has not yet been found". While this is not a false concept, it does not do justice with the now-budding graphene world. It can easily be stated that many graphene applications are being developed. This has been true for years, but various commercial products are starting to pop up, hopefully heralding the beginning of a more steady stream of commercialization.

Among these applications, one can point to cooling technology like Cryorig's CPU cooling system or Huawei's Mate 30 X smartphone, which sports a graphene film cooling technology. Various footwear and sports equipment products have also been launched, along with more technical products like oil additives and coatings. The list goes on and on, and there are even graphene-enhanced sanitary napkins on the market!

Abalonyx reports strong revenue growth in 2018

Norway-based Graphene Oxide developer Abalonyx reports that its graphene oxide sales have increased by about 80 % in 2018, and this follows a 70% increase in 2017 compared to 2016. The company expects to see further strong sales growth in 2019.

Graphene Oxide production cost estimate (Sep 2018, Abalonyx)Abalonyx says that over 90% of its sales derive from returning industrial partners. The company also revealed two of these customers: ORA Graphene Audio with its GO membranes and Provexa AB which developed an anti-corrosion protection coating that is now being used on Scania trucks.
