Product: SEM
The picture was taken after the growth by CVD of silicon nanowires on a copper foil with gold on top. When I saw it I remembered the perturbation caused by sun storms on magnetic field of the earth. These nanowires will be used to manufacture anodes of ion-Li batteries.

Torilis Arensis

Product: SEM
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).
