Silver Clusters - Invisible Worlds

Silver clusters deposited by thermal evaporation onto self-assembled polystyrene nano-spheres (900 nm). Inspect F SEM FEG @ Nanofacility Piemonte INRIM. Self-assembled polystyrene nanospheres are used as masks for thin films and materials nanostructuration on large area. Maybe the subject doesn't match the topics of this year, but surely the title fits.

The invisible ancient ruins

I was having breakfast when I noticed some strange looking mold on the wood of the table where I was sitting. I was only expecting an amorphous surface when looking at the mold with the scanning electron microscope but those blue crystals on the image appeared … What are those strange crystals on the mold? They seem to be some ancient elven ruins from the micro world we cannot see with our eyes…

Chromium Hexacarbonyl Horns

Chromium hexacarbonyl vapour was carried by argon through a heated capillary and impinged onto silicon substrate. Due to the temperature of the capillary, the chromium hexacarbonyl dissociated upon impact and chemisorbed onto the surface - forming horns growing towards the axis of the capillary.

Crystalline rainbow

Crystals of dyes adsorbed on the surface of a biopolymer after a process of water purification. One of the most common and undesirable contaminants in the wastewater are the dyes. They are highly visible, stable and difficult to biodegrade. For removal of such contaminants are commonly used adsorption techniques.

Torilis Arensis

Torilis arvensis is commonly known as Spreading Hedge Parsley. The plants grow up to 3 feet in height with tiny flowers clustered in small flat-topped umbels. T. arvensis fruit (schizocarp) measure 4-6mm and usually hold 2-4 individual seeds (mericarps). The schizocarp is covered with velco-like appendages which attach to clothing and fur allowing them to hitch a ride to new terrain.  This sample was air dried, mounted onto an aluminum stub and sputter coated with gold.  It was viewed on a Philips XL30 TMP SEM at 20 kV in the EM Lab of the Department of Pathology and Laboratory Medicine at UCDavis. The image was colorized using Adobe PhotoShop Elements 2.0 software. The image shows one of the seeds within the schizocarp and affords a better appreciation for their cunning hitch-hiking techniques. Note the various velco-like appendages. The more "thorny" limbs (tan) are found on the schizocarp while the blunt appendages are part of the mericarp. Pollen (yellow) can be seen on the flower surfaces (pink).
