The National Graphene Institute (NGI) has signed a collaborative partnership with a leading UK graphene company to accelerate the commercialisation of applications.
Graphene research covers a spectrum of academic fields and disciplines. These, the latest academic papers published by researchers at The University of Manchester, showcase the ground-breaking work underway right now into the applications of this extraordinary material. The breadth of research taking place at the University and the National Graphene Institute (NGI) demonstrates that the potential for graphene applications is only limited by time and imagination.
Graphene-based materials can have well-defined nanometer pores and can exhibit low frictional water flow inside them, making their properties of interest for filtration and separation. We can investigate permeation through micrometer-thick laminates prepared by means of vacuum filtration of graphene oxide suspensions.

Capacitance measurements provide a powerful means of probing the density of states. The technique has proved particularly successful in studying 2D electron systems, revealing a number of interesting many-body effects. Here, we use large-area high-quality graphene capacitors to study behavior of the density of states in this material in zero and high magnetic fields.

Using a general symmetry-based approach, we provide a classification of generic miniband structures for electrons in graphene placed on substrates with the hexagonal Bravais symmetry.

We report experimental data and theoretical analysis of Coulomb drag between two closely positioned graphene monolayers in a weak magnetic field. Close enough to the neutrality point, the coexistence of electrons and holes in each layer leads to a dramatic increase of the drag resistivity.

Plasmonics allows manipulation of light at the nanometer scale, with potential applications for super-fast, subwavelength optics. Incorporating graphene into plasmonic metamaterials has potential applications for novel active optical devices, exploiting the high sensitivity of graphene to bias voltage to enable control of the plasmonic resonances.

The quantum capacitance of graphene can be negative when the graphene is placed in a strong magnetic field, which is a clear experimental signature of positional correlations between electrons. Here we show that the quantum capacitance of graphene is also strongly affected by its dielectric polarizability, which in a magnetic field is wave-vector dependent.
