Aecom uses graphene by Versarien to 3D print an arch that may modernize transport networks

Global infrastructure services firm Aecom is reportedly developing one of the UK’s first 3D-printed commercial products made from graphene-reinforced polymer.

Aecom has produced a graphene arch using additive manufacturing techniques. It believes the method could reduce the time and cost of installing digital signalling systems and transform the digitization of transport networks. The 4.5-meter high, lightweight arch is being tested on outdoor track at Network Rail’s workforce development center in Bristol.

Riptron to work with Tunghsu Optoelectronics to advance graphene sensors

Riptron, a spin-out company from the University of Manchester, has entered a partnership with China-based Tunghsu Optoelectronics to advance graphene sensors designed to measure the quality of air. The graphene-based sensors are expected to enter mass production shortly following the partnership between the two companies.

In this context, Riptron will secure around £1 million investment over two stages from Tunghsu Optoelectronics.

Israel and China to collaborate on new nanotechnology center to be established in Israel

Israel's Bar Ilan University (BIU) will establish a nanotechnology excellence center in collaboration with the Chinese Academy of Sciences (CAS). The new center at the BIU will include a laboratory to focus on nanomedicine research and two-dimensional (2D) materials engineering, mainly producing graphene.

According to BIU, the main task of the joint research lab is to integrate teamwork of Chinese and Israeli researchers with the participation of industrialists from both countries.

A combination of strong and weak GO flakes can yield stronger GO paper

Researchers from Northwestern University have recently shown that graphene oxide “paper” can be made by mixing strong, solid GO flakes with weak, porous GO flakes. This finding may aid the production of higher quality GO materials, and also sheds light on a general problem in materials engineering: how to build a nano-scale material into a macroscopic material without losing its desirable properties.

“To put it in human terms, collaboration is very important,” said Jiaxing Huang, Northwestern Engineering professor of materials science and engineering, who led the study. “Excellent players can still make a bad team if they don’t work well together. Here, we add some seemingly weaker players and they strengthen the whole team.”

Samsung rumored to launch phone with graphene battery next year

Samsung logoSamsung may be in the race to develop a graphene-based alternative to lithium-ion batteries for its phones. Rumors are going around claiming that the Company hopes to have at least one phone with a graphene battery ready next year or by 2021.

The word is that these graphene-based batteries will be capable of a full charge in under a half-hour, but they still need to raise capacities while lowering costs. In 2017, Samsung said its researchers developed a "graphene ball" material that enables five times faster charging speeds than standard lithium-ion batteries.

Novel device architecture based on graphene Schottky diode varactors shows potential for optoelectronics applications

Researchers from Bar-Ilan University in Israel and Yale University in the U.S have reported on a novel device architecture comprising graphene Schottky diode varactors. The team assessed that such devices have great potential for optoelectronics applications.

The team has shown that graphene varactor diodes exhibit significant advantages compared with existing graphene photodetectors, including elimination of high dark currents and enhancement of the external quantum efficiency (EQE).

Versarien clarifies Chinese expansion plans

Versarien LogoVersarien released details on the Company's expansion plans for its graphene business in China, which in the past were referred to as a "term sheet" with the Beijing Institute of Graphene Technology ("BIGT").

According to Versarien, the term sheet "envisaged that BIGT would provide funding to Versarien for the proposed wholly owned subsidiary ("WFOE") and other corporate purposes in the form of an equity investment".
