Squalane is a hydrocarbon derived by hydrogenation of squalene. 3d illustration
This is a patterned 300 mm silicon wafers on a white background.  Electronic circuit designs have been built onto the wafers using micromaching including photolithography.  The different colors on the wafer come from the different materials on its surface and the diffraction of light.  A person is holding the wafer with two gloved hands.

Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.
