Stem cells support lifelong maintenance of adult organs, but their specific roles during injury
are poorly understood. Here we demonstrate that Lgr6 marks a regionally restricted …

Direct correlation of structural and optical properties on the nanoscale is essential for rational
synthesis of nanomaterials with predefined structure and functionality. We study optical …

All fiber lasers to date emit radiation only along the fiber axis. Here a fiber that exhibits laser
emission that is radially directed from its circumferential surface is demonstrated. A unique …

The functional heterogeneity of resident stem cells that support adult organs is incompletely
understood. Here, we directly visualize the corneal limbus in the eyes of live mice and …

We report the growth and characterization of ternary Al x Ga 1−x As nanowires by metalorganic
chemical vapor deposition as a function of temperature and V/III ratio. Transmission …

Atr is a serine/threonine kinase, known to sense single-stranded DNA breaks and activate
the DNA damage checkpoint by phosphorylating Chek1, which inhibits Cdc25, causing cell …

We demonstrate the controlled growth of coaxial nanocables composed of GaP/ZnS core–shell
structures by a facile chemical vapor deposition method. Structural analysis confirms that …

We report the controlled synthesis of AlN/GaN multi-quantum well (MQW) radial nanowire
heterostructures by metal–organic chemical vapor deposition. The structure consists of a single…

Metallic nanoparticles play a crucial role in nanowire growth and have profound consequences
on nanowire morphology and their physical properties. Here, we investigate the evolving …

Nanowalls are novel nanostructures whose networked morphology holds potential for
applications such as solar cells and gas sensors. The realization of such nanowall-based devices …
