Hedgehog particles and other amazing nanotechnology images
(Nanowerk News) Here is another installment of our collection of amazing images from nanotechnology labs from all over the world. You can find other nanotechnology images here . Visualization methods provide an important tool in materials science for the analysis and presentation of scientific work. Images can often convey information in a way that tables of data or equations cannot match. Occasionally, scientific images transcend their role as a medium for transmitting information, and contain the aesthetic qualities that transform them into objects of beauty and art. As a special feature of recent MRS Meetings, the MRS has offered the popular Science as Art competitions, with entry open to all registered meeting attendees. The images below represent the winners of the 2013 MRS Spring Meeting Science as Art competition. You can see all galleries here on the MRS website: Science as Art
“Hedgehog” Particles – particles with nano-scale corrugation are sculpted by interfacial growth of rigid ZnO nanowires on polymeric microspheres. (Image courtesy of the Materials Research Society Science as Art Competition and Joong Hwan Bahng, University of Michigan-Ann Arbor)

Tetraaniline in Full Bloom – A SEM image of a thin-sheet network composed of doped aniline oligomers. The aggregated sheets in the upper right corner forms a cluster that mimics the look of a flower, whereas other flexible sheets represents leaves and stems. The background and the “leaves” were kept in black and white to give prominence to the beauty and brightness of the “flower”. Scientifically, this morphology combines high surface area and electrical conductivity, rendering it ideal for organic supercapacitors and sensors.

On the Beach, At Night – A composite of three scanning electron microscope images taken at different focal lengths of a carbonized silicon nanowire array. Utilizing the NovelX mySEM low voltage imaging system, the near and far range images were taken with standard backscatter collection while the middle range image was taken using the Topo mode in order to capture the relief of the silicon “dunes”. The three images were combined and colorized in photoshop. This scene takes its name from the Walt Whitman poem which describes the interconnected nature of the Universe, and the “vast similitude that interlocks all.” While we work on the nanoscale, our efforts have impact on the way humans interact with the world on the macroscale. As well we find reflections of our macro world forms in the shapes and forms of the nano one.
