Let’s delve into the recent breakthroughs in the market for graphene and other 2D materials and explore their widespread impact on various industries.?

1. Unconventional Superconductivity in Graphene's Magic-Angle Superlattices?

The awareness about intrinsic unconventional superconductivity in graphene superlattices, especially at small twist angles close to the 'magic' angle, has triggered major interest in recent times. When two graphene layers are stacked with a precise twist angle, the electronic band structure flattens, leading to correlated insulating states. By tuning the electrostatic doping, these insulating states can be easily altered, resulting in zero-resistance states with critical temperatures up to 1.7 K. The simplicity and tunability of this system make it an ideal platform for studying strongly correlated phenomena and high-temperature superconductivity.? ?

1. Graphene's Viscous Electron Flow and Hydrodynamic Behavior:?

One of the most exciting recent discoveries involves the behavior of electrons in graphene when encapsulated in hexagonal boron nitride (hBN). Researchers found that electrons exhibit a highly viscous fluidic behavior like classical liquids, leading to hydrodynamic effects. This unique property has significant implications for electronic device fabrication. In graphene constrictions, a 'superballistic' conductance has been observed, attributed to a collective electron viscous flow. This behavior not only challenges traditional understanding but also offers opportunities for the creation of improved graphene-based devices.??

Graphene's impermeability to most gases and liquids, except hydrogen, has led to its exploration as a membrane for molecular sieving. While achieving the required density and pore uniformity for industrial applications remains a challenge, graphene oxide (GO) membranes have emerged as a feasible alternative. These GO membranes, formed by interlocked crystallites, exhibit remarkable properties, such as electrically controllable water permeation and tunable ion diffusion. Additionally, graphene and other single-layer 2D materials, like hexagonal boron nitride and mica, have proven to be excellent proton conductors, holding promise for applications in separation technologies and fuel cells.?
