Skeleton Technologies to invest €25 million in German plant

Skeleton Technologies, an Estonia-based company that produces graphene-based supercapacitors and energy storage systems, is to invest €25 million in its plant located in the German state of Saxony. With this investment, Skeleton aims to expand its research and development as well as scale its production.

Skeleton Technologies to invest €25 million in German plant

"In 2017, we announced our first stage in Saxony — €6.2 million were invested in the production of ultracapacitors in Großröhrsdorf," Skeleton co-founder and CEO Taavi Madiberk said in a press release. "We have successfully entered the market and helped save fuel and reduce emissions from buses, trucks, railway vehicles and industrial machinery".

Versarien reports progress on collaboration with Beijing Institute of Graphene Technology

Versarien LogoVersarien recently reported that it has signed a term sheet with Beijing Institute of Graphene Technology covering the proposed cooperation between the parties to develop Versarien's graphene business in China.

Subject to the completion of due diligence and the entering into of formal documentation, the term sheet will see Beijing Institute assisting Versarien with the establishment of a wholly-owned subsidiary in China. The subsidiary would focus on the manufacture of Versarien's graphene and other 2D materials in China and their sale to Chinese customers.

Graphene-based foam maintains texture at extreme temperatures

Researchers from Nankai University in China and Rice University in the U.S. have developed a type of graphene-based foam that retains its texture when exposed to extremely cold temperatures.

The researchers note that almost all materials become more brittle and stiffer when exposed to very cold temperatures, often leading to loss of strength. In this new work, the researchers sought to find a material that would spring back after being crushed while exposed to extreme temperatures. To that end, they turned to graphene as a possible solution.

Archer Exploration prints human antibodies on graphene biosensors

Archer Exploration has printed and patterned ink formulations of human antibodies on graphene-based biosensor components derived from the company’s Campoona graphite. Archer reports that ink formulations comprised primarily of human antibody immunoglobulin G (IgG) as the active constituent were successfully prepared and printed using proprietary methods.

The IgG inks were printed on resin-coated paper and a number of graphene-based electrodes and were able to withstand the chemical and physical processes in the formulation, printing, and post-printing steps.

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.

Graphene inks help stabilize the stability of perovskite solar cells

Researchers from the Graphene Flagship have developed hybrids of graphene and molybdenum disulphide quantum dots to stabilize perovskite solar cells (PSCs). PSCs are a novel type of solar cells which are efficient, relatively easy to produce, made with cheaper materials and, due to their flexibility, can be used in locations where traditional silicon solar cells cannot be placed.

A collaboration between the Graphene Flagship Partners Istituto Italiano di Technologia, University of Rome Tor Vergata, and BeDimensional resulted in a novel approach based on graphene and related materials to stabilize PSCs, thus addressing the stability issue of PSCs, a major hurdle hindering their commercialization.

Directa Plus doubles revenues in 2018

Directa Plus logoDirecta Plus has reported that it more than doubled annual revenues, as its various commercial partnerships started to generate orders. Total income in 2018 reportedly rose to €2.5 Million (compared to last year's €1.23 Million) with sales of €2.25 Million (compared to last year's €1 Million) if grants are excluded.

Directa has projects ongoing to incorporate graphene into textiles, pollution treatments and road surfaces.

Graphene may enable sensitive, fast and efficient photodetectors for future terahertz cameras

Scientists from ICFO have developed a novel graphene-enabled photodetector that operates at room temperature, and is sad to be highly sensitive, very fast, with a wide dynamic range and covers a broad range of THz frequencies.

Detecting terahertz (THz) light is extremely useful for two main reasons: First, THz technology is becoming a key element in applications regarding security (such as airport scanners), wireless data communication, and quality control but current THz detectors have shown strong limitations in terms of simultaneously meeting the requirements for sensitivity, speed, spectral range, being able to operate at room temperature, etc. Second, it is a very safe type of radiation due to its low-energy photons, with more than a hundred times less energy than that of photons in the visible light range.

Purdue team uses graphene foams to power spacecraft

Researchers at Purdue University’s Maurice J. Zucrow Laboratories are developing a new propellant formulation method that will use graphene foams to power spacecraft. The research is reportedly showing success at increasing burn rate of solid propellants that are used to fuel rockets and spacecraft.

“Our propulsion and physics researchers came together to focus on a material that has not previously been used in rocket propulsion, and it is demonstrating strong results,” said Li Qiao, an associate professor of aeronautics and astronautics in Purdue’s College of Engineering.

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.
