We develop an analytical framework for self-stabilizing optical manipulation of freestanding metasurfaces in three dimensions. Our reveals that the challenging problem stabilization against translational and rotational perturbations dimensions is reduced to a simpler scattering analysis metasurface unit cell two derive universal stiffness coefficients applicable arbitrary three-dimensional radi...

This paper represents the first installment of a larger project devoted to the relevance of pragmatism for bioethics. One self-consciously pragmatist move would be to return to the classical pragmatist canon of Peirce, James and Dewey in search of substantive doctrines or methodological approaches that might be applied to current bioethical controversies. Another pragmatist (or neopragmatist) m...

Freestanding graphene membranes are unique materials. The combination of atomically thin dimensions, remarkable mechanical robustness, and chemical stability make porous and non-porous graphene membranes attractive for water purification and various sensing applications. Nanopores in graphene and other 2D materials have been identified as promising devices for next-generation DNA sequencing bas...
