Doped graphene shows promise for sodium-ion batteries

Scientists at EPFL have recently published a research that could open up new pathways to boosting the capacity of sodium-ion batteries. “Lithium is becoming a critical material as it is used extensively in cell-phones and car batteries, while, in principle, sodium could be a much cheaper, more abundant alternative,” says Ferenc Simon, a visiting scientist in the group of László Forró at EPFL. “This motivated our quest for a new battery architecture: sodium doped graphene.”

Since sodium is far more abundant than lithium, and the risk of fire is much lower with this battery chemistry, it is considered a potentially viable replacement to current lithium-ion technology. But sodium also has much lower energy density than lithium, which has so far limited uptake, particularly in the electric vehicle and consumer electronics segments, where the physical size of the battery is a deciding factor. EPFL's new work uses graphene to address this issue.

Zen Graphene Solutions completes first tranche of private placement

Zen Graphene Solutions logo imageZen Graphene Solutions has announced the closing of the first tranche of its previously announced private placement of units.

The Company raised gross proceeds of CAD$1,077,294.80 (around USD $788,115) under the Offering, which will be used to fund ongoing work on the Albany Graphite Project including graphene research and scale up, COVID-19 initiatives and other graphene applications development and for general corporate purposes. A second tranche is expected to close shortly in line with previous interest received.

Haydale and IRPC progress to phase 2 of conductive ink development project

Haydale logoHaydale has announced that, further to a successful Phase 1 collaboration agreement with IRPC Public Company (IRPC), a Phase 2 collaboration agreement has now been signed between the two companies. The Agreement will see IRPC developing transparent graphene and functionalized acetylene black conductive inks for RFID, NFC and related applications.

Haydale is to functionalize IRPC's acetylene black product to create the organic RFID ink. The success of this collaboration is expected to pave the way to numerous opportunities in printed electronic applications and be more environmentally friendly than existing inks.

Researchers create a mechanically-tunable graphene quantum dot

Researchers at Delft University of Technology (TU Delft) recently presented what they say is the first mechanically-tunable monolayer graphene QD whose electronic properties can be modified by in-plane nanometer displacements.

The ability to precisely manipulate individual charge carriers can be considered as a cornerstone for single-electron transistors and for electronic devices of the future, including solid-state quantum bits (qubits). Quantum dots (QDs) are at the heart of these devices.

New graphene-based approach enables the study of individual organic molecules and nanolayers of molecules

Scientists from the Center for Photonics and 2D Materials of the Moscow Institute of Physics and Technology (MIPT), the University of Oviedo, Donostia International Physics Center, and CIC nanoGUNE have proposed a new way to study the properties of individual organic molecules and nanolayers of molecules. The approach is based on V-shaped graphene-metal film structures.

Nondestructive analysis of molecules via infrared spectroscopy is vital in many situations in organic and inorganic chemistry: for controlling gas concentrations, detecting polymer degradation, measuring alcohol content in the blood, etc. However, this simple method is not applicable to small numbers of molecules in a nanovolume. In their recent study, the research team proposed a way to address this issue.

U.S researchers design new graphene-based printed sensors to monitor food safety

Researchers at Iowa State University and Northwestern University have developed graphene sensors that are printed with high-resolution aerosol jet printers on a flexible polymer film and tuned to test for histamine, an allergen and indicator of spoiled fish and meat.

The U.S. Food and Drug Administration has set histamine guidelines of 50 parts per million in fish, while the sensors were found to detect histamine down to 3.41 parts per million. This validates that the sensors are more than sensitive enough to track food freshness and safety.

Graphene-enhanced asphalt to be tested in Dartford, UK

Highways contractor Amey and its client Kent County Council will be testing Gipave, an Italian graphene-based asphalt supermodifier said to extend pavement life.

The trial is taking place as part of the Association of Directors of Environment, Economy, Planning & Transport (ADEPT) Smart Places Live Labs programme funded by the Department for Transport of the UK.
