…that electrons seem to carry “fractional charges” in pentalayer graphene—a structure made of five stacked graphene layers placed on a similar sheet of boron nitride. Unveiling Fractional Charges Ju discovered…
Nanoparticles of cobalt attach themselves to a graphene substrate in a single layer. As a catalyst, the cobalt-graphene combination was a little slower getting the oxygen reduction reaction going, but…
…transistors. The team’s understanding of how graphene growth is influenced by differing amounts of surface oxygen is a major step toward improved high-quality graphene films at industrial scale. The team’s…
…the University of Swansea, had to create patterned graphene devices using a large substrate area, which was not possible using the traditional exfoliation technique where layers of graphene are stripped…
…frustrating catch-22 issue of stability and reproducibility that meant that graphene-based junctions were either mechanically stable or electrically stable but not both at the same time. Graphene and graphene-like molecules…
…In this system the Columbia researchers achieve unprecedented control over monolayer graphene’s bandstructure within a single device, by mechanically rotating boron nitride atop graphene aligned to a bottom BN slab.”…
…Essentially the team was able to “tune graphene to behave at two electrical extremes.” “So by creating this moiré structure, graphene is not graphene anymore. It almost magically turns into…
…acceleration. Graphene is known as the world’s thinnest and strongest 2D material, which is suitable for laser-driven ion sources. Graphene’s Unique Properties for Laser-Ion Acceleration “Atomically thin graphene is transparent,…
…gut microbiome, and immunity has been the subject of the present study performed using zebrafish. The nanomaterial investigated was graphene oxide, which can be described as a relative of graphene…
Recent research indicates that controlled inhalation of ultra-pure graphene oxide does not have short-term adverse effects on human lung or cardiovascular health, marking a significant step in safely harnessing graphene’s…
A new method using rotaxane structures to cross-link graphene layers enhances the flexibility, strength, and conductivity of graphene films, with potential applications in advanced electronics and mechanical tools. Credit: SciTechDaily.com…
Symbolic illustration of a graphene layer on a microchip. In combination with a heavy-metal thin film and ferromagnetic monolayers, graphene could enable spintronic devices. Credit: © Dall-E/arö, edited Spintronics offers…
…Bilayer Graphene and Valleytronics Bilayer graphene, which consists of two stacked layers of graphene, has a special ability to adjust its electronic band gap using externally applied electric fields. This…
…like graphene would make it act like graphene,” Kaman said. “I thought it would maybe have a handful of similar properties to graphene, but the analogy was much deeper and…
…graphene oxide in a solution. At right, graphene oxide is added to simulated nuclear waste, which quickly clumps for easy removal. Credit: Anna Yu. Romanchuk/Lomonosov Moscow State University A newly…
…researchers found, graphene can effectively filter electrons according to the direction of their spin, something that cannot be done by any conventional electronic system. Under typical conditions, sheets of graphene…
