Russian researchers have proposed a new method for synthesizing high-quality graphene nanoribbons—a material with potential for applications in flexible electronics, solar cells, LEDs, lasers, and more. Presented in The Journal of Physical Chemistr.....»»
Powerful graphene hybrid material for highly efficient supercapacitors
A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly efficient supercapacitor. The basis of the energy storage device is a novel, powerful and also sust.....»»
Two dimensional heterostructures composed of layers with slightly different lattice vectors
New periodic structures known as moiré lattices can be observed in two-dimensional (2-D) heterostructures containing layers with slightly different lattice vectors, which can in turn support new topological phenomena. It is therefore important to ob.....»»
Ultra-fast gas flows through tiniest holes in 2-D membranes
Researchers from the National Graphene Institute at the University of Manchester and the University of Pennsylvania have identified ultra-fast gas flows through the tiniest holes in one-atom-thin membranes, in a study published in Science Advances......»»
New discovery brings analog spintronic devices closer
The observation of nonlinearity in electron spin-related processes in graphene makes it easier to transport, manipulate and detect spins, as well as spin-to-charge conversion. It also allows analog operations such as amplitude modulation and spin amp.....»»
A new method for the functionalization of graphene
An international research team involving Professor Federico Rosei of the Institut national de la recherche scientifique (INRS) has demonstrated a novel process to modify the structure and properties of graphene. This chemical reaction, known as photo.....»»
"Magic" angle graphene and the creation of unexpected topological quantum states
Electrons inhabit a strange and topsy-turvy world. These infinitesimally small particles have never ceased to amaze and mystify despite the more than a century that scientists have studied them. Now, in an even more amazing twist, physicists have dis.....»»
When less is more: A single layer of atoms boosts the nonlinear generation of light
In a new study an international research team led by the University of Vienna has shown that structures built around a single layer of graphene allow for strong optical nonlinearities that can convert light. The team achieved this by using nanometer-.....»»
Phosphorus equivalent of graphene makes reconfigurable transistors
May be useful for security, as it’s hard to tell how the circuitry might execute. Enlarge / One gate, two behaviors. (credit: Peng Wu et al.) At the moment, our processors are built on silicon. But fundamental limits on what can be done with.....»»
