Graphene-Info: the graphene experts

Researchers at the University of Adelaide have developed a simple, low-cost prototype sensor that quickly and easily detects small amounts of methanol in breath. This is a step toward developing a “methanol breathalyzer” to efficiently diagnose poisonings.

The team formulated a specialized electrically conductive ink that combined a zirconium-based metal-organic framework (MOF) and graphene. They then 3D-printed the ink onto a ceramic, creating the sensor. A machine created artificial breath by blending dry air with humid air containing methanol and then mimicked blowing the breath into a chamber containing the sensor. The prototype detected methanol at concentrations as low as 50 parts per billion (below the levels found in breath during methanol poisoning) and maintained its stability and performance after several repeated sensing cycles.

Researchers form Boise State University and University of Idaho have developed a technique that leverages biocompatible graphene foam to communicate with cells and help induce cartilage formation. 

In this work, the researchers aimed to develop new techniques and materials that can hopefully lead to new treatments for osteoarthritis through tissue engineering. Osteoarthritis is driven by the irreversible degradation of hyaline cartilage in the joints which eventually leads to pain and disability with complete joint replacement being the standard clinical treatment. Using custom designed and 3D printed bioreactors with electrical feedthroughs, they delivered brief daily electrical impulses to cells being cultured on 3D graphene foam.

Researchers from ICFO, Princeton University, Donostia International Physics Center (DIPC), National Institute for Materials Science and Ludwig Maximilian University of Munich have detected two electronic ‘species’ coexisting in magic-angle twisted bilayer graphene. The technique, based on thermoelectric measurements, provides insight into the strongly-correlated phases of this condensed matter platform.

“This had been hinted at experimentally before, but lacked direct evidence, which we have provided for the first time,” shares ICFO's Dr. Rafael Luque Merino, first author of the article. One of the species corresponds to itinerant electrons, similar to the ‘usual’ free electrons. Such electrons can move across the material, carrying charge and heat. Due to their high mobility, and low effective mass, they are sometimes referred to as ‘light carriers’. The other species resides in highly localized orbitals and interact very strongly between them, which causes a drastic reduction of their mobility. Consequently, these ‘heavy carriers’ do not contribute significantly to charge and heat transport.

Researchers from Boise State University and Science Applications International Corporation have developed a new process utilizing copper-plated laser-induced graphene (LIG) to create direct-write, on-demand flexible electronics.

The novel approach to manufacturing flexible hybrid circuits could offer such benefits as reducing costs, waste, and environmental impact. Laser induced graphene uses a single-step laser manufacturing process that converts carbon-rich materials into a 3-dimensional conductive and porous structure with some regions of atomically thin graphene. This technique is scalable, cost-effective, and patternable, making it ideal for applications in electronics, sensing, and energy storage.

Korea-based TwoDM has developed a new packaging technology to extend the shelf life of instant rice by up to three months. In a recent interview in the Korean press, Kim Young-jin, co-chief executive officer (CEO) of TwoDM Co., said that the company recently finalized development of a new container that dramatically blocks moisture and oxygen, which allows instant rice to last up to 12 months instead of the usual 9 months.

The technology uses a graphene barrier developed by TwoDM and manufactured into containers by Dae-A C&I.
