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.

Developing Glandular Trichomes of Basil

Formation of glandular trichomes on lower leaf surface of a young leaf of basil (Ocimum basilicum). The smaller trichomes with four evident cells have just formed and the cuticles covering their four glandular cells still adhere to the glandular cells. Three of the larger trichomes are more mature and essential oils secreted from the glandular cells of these trichomes have caused the cuticles covering them to separate from the cells and balloon outward, hiding the glandular cap cells below. This unfixed leaf was imaged with an FEI Quanta 200F SEM in environmental mode at Washington State University’s Franceschi Microscopy and Imaging Center. Scale bar = 150 µm.
