Iron Egg

This image shows a solidified droplet of iron sitting atop an alumina substrate. This was the result of a study into the co-siterability of these two materials in efforts to improve their wetting characteristics. The textured surface of the droplet is believed to be to result of very fine grain growth of the metal during its rapid cooling.

Zinc crystals

Zinc crystals that have been adsorbed on the surface of an alginate gel after being subjected to a process of wastewater treatment. An important field of application of the alginates gels is the protection of the environment: alginate gels are used as adsorbents for the removal of heavy metals such as cadmium, zinc, lead, chromium and mercury in wastewater.

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.
