Tiny self-powered temperature sensors built with graphene

Researchers have demonstrated that graphene can be used to build sensitive and self-powering temperature sensors. The findings pave the way for the design of highly sensitive thermocouples, which could be integrated in nanodevices and even living cells.

Substances trapped in graphene nanobubbles exhibit unusual properties

Scientists modeled the behavior of nanobubbles appearing in van der Waals heterostructures and the behavior of substances trapped inside the bubbles. The new model will help obtain equations of state for substances in nano-volumes, opening up new opportunities for the extraction of hydrocarbons from rock with large amounts of micro- and nanopores.

Protocol identifies fascinating quantum states

Topological materials attract great interest and may provide the basis for a new era in materials development. Physicists now present a new measuring method that allows to identify and characterize so-called topological invariants on various experimental platforms.
