Graphene nano-ribbons could help build future integrated circuits

University of California researchers, along with teams from other U.S-based institutions like Columbia University, Lawrence Berkeley National Laboratory and University of Washington, have created a metallic wire made entirely of carbon, setting the stage for a ramp-up in research to build carbon-based transistors and, ultimately, computers.

"Staying within the same material, within the realm of carbon-based materials, is what brings this technology together now," said Felix Fischer, UC Berkeley professor of chemistry, noting that the ability to make all circuit elements from the same material makes fabrication easier. "That has been one of the key things that has been missing in the big picture of an all-carbon-based integrated circuit architecture."

Novel graphene-based sensors function in harsh environments

King Abdullah University of Science and Technology (KAUST) and University of California Berkeley researchers have found that graphene-based sensors can perform in harsh environments that are inhospitable to other existing technologies.

"Graphene has been projected as a miracle material for years now, but its application in harsh environmental conditions was unexplored," says Sohail Shaikh, who has developed the new sensors, together with KAUST's Muhammad Hussain. "Existing sensor technologies operate in a very limited range of environmental conditions, failing or becoming unreliable if there is much deviation," Shaikh adds.

ZEN Graphene Solutions develops a graphene-based ink with 99% virucidal activity against COVID-19

Zen Graphene Solutions logo imageZEN Graphene Solutions has reported that it has developed a novel graphene-based virucidal ink with 99% effectiveness against COVID-19. ZEN’s Virucidal ink was reportedly also 99% effective a minimum of 35 days after application to N95 mask material.

ZEN is now developing plans to expedite commercialization of this product, pending regulatory approval, and has filed a provisional patent for this graphene-based virucidal product.

Graphene-based platform enables real-time monitoring of the molecular self-assembly process at the solid/liquid interface

Researchers from the University of Strasbourg & CNRS (France), in collaboration with Humboldt University of Berlin and DWI – Leibniz Institute for Interactive Materials/RWTH Aachen University in Germany, have shown that graphene devices can be used to monitor in real time the dynamics of molecular self-assembly at the solid/liquid interface.

Molecular self-assembly on surfaces is an attractive strategy to provide substrates with specific properties. Understanding the dynamics of the self-assembly process is vital in order to master surface functionalization. However, real-time monitoring of molecular self-assembly on a given substrate has proven complicated by the challenge to disentangle interfacial and bulk phenomena.

Paragraf’s graphene Hall Effect sensors found to be resistant to neutron irradiation

In June 2020, Paragraf entered into a working partnership with the Magnetic Measurement section at CERN, the European Organization for Nuclear Research, to demonstrate how new opportunities for magnetic measurements are opened up through the unique properties of its graphene sensor, particularly its negligible planar Hall effect. Now, Paragraf has demonstrated the ability of its graphene Hall Effect sensors to withstand high levels of radiation.

This conclusion, based on testing from the National Physical Laboratory (NPL), proves that ‘unpackaged’ Hall Effect sensors can be used in high-radiation environments such as space. The project was funded by Innovate UK, the UK’s innovation agency.

Graphene quantum dots help check water content in soil

A recent study by researchers at Gauhati University, Indian Institute of Technology Bombay and DAIICT in India has demonstrated a soil moisture sensor made from graphene quantum dots, which are nanometer-sized fragments of graphene.

Water sensors are vital for various agriculture applications, like keeping track of the watering schedule for a large number of plants, such as for a field of crops. Soil moisture sensors measure the water content in the soil to avoiid crop destruction by under or over watering the field.
