First Graphene, Breedon Group, Morgan Sindall Construction and the University of Manchester develop graphene-enhanced cement

First Graphene will work with the Breedon Group, Morgan Sindall Construction & Infrastructure and the University of Manchester to develop a new reduced-CO2 graphene-enhanced cement. The consortium is currently formulating the cement using varying doses of First Graphene’s PureGRAPH graphene-enhanced grinding aid. The project received a research grant from the UK government earlier in 2022.

First Graphene says that the study involves one of the largest commercial trials of its kind to date globally.

Researchers realize zero-bias operation of a graphene photodetector

NTT Corporation and the National Institute for Materials Science (NIMS) have jointly reported the realization of what they define as "the world's fastest zero-bias operation (220 GHz) of a graphene photodetector (PD)". The research conducted by NTT and NIMS has also, according to the statement, clarified the optical-to-electrical (O-E) conversion process in graphene for the first time.

Graphene is a promising photodetection material for enabling high-speed O-E conversion at wavelength ranges where existing semiconductor devices cannot operate, thanks to its high sensitivity and high-speed electrical response to a wide range of electromagnetic waves, from terahertz (THz) to ultraviolet (UV). However, until now, the demonstrated zero-bias operating speed has been limited to 70 GHz due to conventional device structure and measurement equipment. For this reason, the challenge for graphene PDs is to demonstrate 200-GHz operation speeds and clarify graphene's inherent properties, such the process of optical-to-electrical conversion.

Zentek updates on testing of icephobic coating technology

Zentek recently announced the successful completion of sand erosion testing at the National Research Council (“NRC”) in Ottawa and rain erosion testing at the Anti-icing Materials International Laboratory (“AMIL”) in Quebec on Zentek’s patent-pending Icephobic Coatings. These results were said to demonstrate that the company’s icephobic technology is durable in adverse conditions for both wind turbine and drone industries, where Zentek is currently maintaining its focus.

“We are very happy with both the performance and durability test results for our icephobic coating and look forward to continued testing and demonstration of our technology,” said Greg Fenton, CEO of Zentek. “Ice accretion is a significant problem in the drone and wind turbine industries with few robust solutions currently available. We believe our patent-pending technology may be a new innovative approach to addressing a significant global need and look forward to continued discussions with drone and wind turbine market participants who see value in potentially more effective icephobic technologies.”

MCR Safety launches graphene-enhanced work gloves

Personal protection equipment maker, MCR Safety, recently introduced CT1071, a new Cut Level ‘E’ safety glove made with graphene fibers. It offers a choice of different coatings designed for different tasks and working environments. CT1071 has a 15-gauge shell specifically designed to take advantage of the ultra-lightweight nature of the new fibers. It’s a Cut Level ‘E’ glove yet it’s reportedly 25% lighter than similar gloves offering the level of protection. It is also designed to be comfortable and easy to wear.

As this fiber isn’t blended with any glass or steel, the high-level cut protection is maintained throughout the life of the glove. No fiber breakage means high durability, high comfort and no irritation. The diaphanous Nitrile Micro-Foam coating enables enhanced grip, even in oily conditions.
