Self assembly of 500 nm polystyrene nanospheres onto optical photoresist. The nanospheres acts like microlenses, exposing the resist and patterning it with a dot structure. After metalisation (in this case sputtered permalloy) the following lift-off leaves the metal structure on the upper pert of the microphoto. In the lower part the original array of self-assembled nanospheres used as microlenses.

Surface microstructure of a nickel oxide (NiO) formed during high temperature oxidation of Ni-based superalloy at 1150 C for 100h. It formed on a single crystal Ni-based superalloy that is commonly applied for jet engine turbine blades and vanes working at temperature of 1100-1200 C.

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 picture above shows cork structure. It is composed of suberin, a hydrophobic substance that has impermeable, buoyant, elastic, and fire retardant properties. Cork's bubble-form structure and natural fire retardant make it suitable for acoustic and thermal insulation in house walls, floors, ceilings and facades. Cork's elasticity combined with its near-impermeability makes it suitable as a material for bottle stoppers, especially for wine bottles. Cork stoppers represent about 60% of all cork based production.

Pyramidal shape (ice cream like) of a GaP nanocolumn tipped by a spherical ball containing Ga + In metallic liquid. The metallic ball is coverd by a carbon nanomembrane. The structure was grown by the Metallorganic Chemical Vapours Phase Technique. The colors were obtained by mixing the signals of secondary and backscattered electrons. The mixing is performed using the software FEI Company.
