Iceni Labs enters MoU with 2DM to develop graphene-based products for the defense, automotive and aerospace markets

Iceni Labs, a spin-out from Imperial College London, has signed a Memorandum of Understanding (MoU) with Singapore’s 2D Materials (2DM) that will see the companies combine their respective expertise to develop and market graphene-based products for the defense, automotive and aerospace markets in Europe, North America and the Middle East.

Iceni Labs, a spin-out from Imperial College London, aims to exploit the properties of graphene for devices aimed at the defense market. 2DM manufactures graphene as an additive to enhance the properties of many industrial materials. The MoU will explore the potential to use 2DM’s graphene as an industrial additive to enhance the properties of Iceni Labs-developed industrial products including microphones, weapons optics devices and coatings.

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.

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.

MediaDevil launches graphene-enhanced earphones

MediaDevil, a UK-based maker of various phone, laptop and tablet accessories, is selling the Artisanphonics CB-01 Earphones - Noise-isolating Premium Wood Earphones with Nanene Graphene-Enhanced Audio.

These earphones, enhanced with Versarien's Nanene material, reportedly sport an earphone diaphragm that is thinner and more flexible than traditional materials can allow. MediaDevil says that independent testing conducted by a leading British premium audio company found that, remarkably, Nanene enhances both the high-end (treble) and the low-end (bass) of the audio frequency wave.

Graphene electronics: commercialisation outlook for 2019

This is a guest post by Guillaume Chansin

Graphene is probably the most hyped material of the past decade, but so far commercial applications have been limited. Graphene is mostly used as an additive inside composites and plastics to enhance their thermal or structural properties. In the most recent high profile case, Huawei announced the integration of a passive graphene cooling film to improve heat management inside one of their smartphones. While this is a useful use of graphene, it is a far cry from the disruptive electronics that were promised when the material was first isolated.

It is worth considering that both investments and patent filings in graphene peaked in 2015. Nearly four years later, we can expect to see some of these to start paying off with some product launches.
