title: Self-coiling of Ag2V4O11 nanobelts into perfect nanorings and microloops.
abstract: Free-standing Ag2V4O11 nanorings and microloops have been synthesized by a simple hydrothermal process without any template or surfactant. The Ag2V4O11 nanorings and microloops have preferred growth direction along the [30] plane and are formed by the self-rolling of Ag2V4O11 nanobelts.
