Dandelions

Hybrid inorganic/polymer based photovoltaic nanodevices offer the promise of low cost large area conversion of solar energy to electricity. Nanostructures of zinc oxide have shown supreme capabilities in emerging technologies ranging from solar energy harvesting to biosensing. However, the ability to control the size and position of these nanostructures is crucial for fabricating nanodevices with remarkable properties and astonishing solar energy conversion efficiencies. Herein, we present a collection of scanning electron micrographs of zinc oxide nanostructures prepared by low temperature hydrothermal methods Image taken and Processed by Luisa Whittaker PhD.

Strained Gold Nanoparticle

The Moiré-fringe image of a 30 nm decahedral gold nanoparticle shows five-fold rotational symmetry (black fringes) that results from serial twinning and shows the internal distortion of the atomic structure (indicated by the gradual change of the color fringes) that accommodates this unique geometry. The Moiré-fringe image was extracted from the original TEM image taken on the spherical-aberration-corrected Tecnai F20 at the CEMES-CNRS in Toulouse, France. Such particles have tremendous potential as components of nanoscale plasmonic devices for imaging, cancer therapy, and biosensing among other applications.
