This Commentary discusses practical prospects of using electrical control of interlayer excitons in van der Waals heterostructures for high-temperature exciton condensation and valley–spin optoelectronics.
The new revisions of the Annexes of the European Union’s chemical legislation with regards to nanomaterials will provide more structure and clarity, but they will also force manufacturers, importers and downstream users to put substantial effort into understanding the details of what should and should not be done.
Initial studies indicate that consumer concerns about nanomaterial use in point-of-use water systems may be overestimated by manufacturers. Nevertheless, manufacturers should continue to focus on building consumer confidence in the safety of their products.
