False-colored SEM image of the surface of a kidney stone. Urolithiasis is a common condition, with a prevalence of about 10%. Various types of urinary calculi have been described upon their mineral content and/or their morphology. The depicted stone is made of calcium phosphate crystals.

These Silicon filaments are the consequence of an ESD (Electrostatic Discharge) stress applied on a MOS Polysilicon Gate. By creating a Gate leakage, they are responsible of the electronic component failure.

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).

The array of micro-gratings fabricated on the facet of violet-blue InGaN semiconductor laser structure using ion beam provides high reflection to light beam emitted from the laser. It looks like array of walls to block, resist and reflect the light beam back to its origin direction.
