International standards have a crucial role in supporting global trade and protecting human health and the environment. US government agencies and the private sector must become more involved in international efforts to establish such standards, and representatives from all nations must ensure that all standards are based on sound science.

Now it has been shown that molecular switches, adsorbed in a homogeneous two-dimensional layer, can be collectively switched with spatial selectivity. The probability of a molecule switching is controlled by the surrounding molecules and the supporting surface. Spatial periodicity in molecular switching

The saturation velocity is attributed to scattering by interfacial phonons in the silicon dioxide layer supporting the graphene channels. These results demonstrate the feasibility of graphene devices for analogue and radio-frequency circuit applications without the need for bandgap engineering.
