Solitary Dog Sculptor I

This image was created from an SEM image of a (100) oriented titania inverse opal.

The image shows the cross-section half way through a (100) plane.

The inverse opal was formed by low temperature atomic layer deposition of titania within the void spaces of a polystyrene opal with a sphere diameter of 330 nm.

The SEM image was acquired at 15kV at 50,000x magnification and subsequently processed with an image manipulation software.

Highly tapered germanium nanowire 'morning star' grown from a surface imperfection, utilizing the vapor-liquid-solid mechanism on an Si (111) substrate.

Imaged via field emission scanning electron microscope at a magnification of 15k, accelerating voltage of 5 kV, and imaged in plan view, normal to the (111) substrate surface.

These structures were obtained by chemical vapor deposition of molecular precursors. This picture presents a collage of SEM images including epitaxial heterojunctions of SnO₂/VOx nanowires and flower-like arrangement of SnO₂ platelets which were obtained at specific parameter combinations.

An artificially-colored scanning electron micrograph of cadmium sulfide "flowers."

These "flowers" are a few microns across and are grown in a multi-stage nucleation and growth process.

Picture taken with an optical microscope at 200x magnification of a ca. 100 nm thick TiO film on a silicon substrate that is beyond the critical thickness and consequently starts to peel off from the surface.

SEM images of the inorganic parts of an invertebrate, colonial marine animal called a bryozoan.

These images were taken for an investigation into the crystallography of the skeletal calcitic elements of this animal.

Nickel coated polystyrene microspheres after reactive ion etching.

The central polystyrene region is etched away more than the metallic nickel, resulting in the dendritic features. (Magnification 25,000x)

Color-enhanced scanning electron micrograph of triangular molybdenum sulfide sheets thermally evaporated onto a silicon substrate.

Such morphology gives rise to a large number of reactive basal edges, which show selective reactivity over the basal faces.

(Magnification 17,000x) Contrast between vibrant colors and grey features imparts a nostalgic touch.

Color-enhanced scanning electron micrograph of a ball cluster of molybdenum sulfide nanocones thermally evaporated onto a silicon substrate.

Each cone is about 300 nm in diameter at the open end.

The film morphology was observed to vary at different deposition temperatures. (Magnification 37,000x) Inspired by the classic beauty and bold simplicity of the elegant Calla Lilies.
