Bismuth Crystal by Paul’s Lab on Flickr
This is a synthetic bismuth crystal. It measures 4x3x2,5 cm and was made by myself, Paul, from www.paulslab.com
Chrome Alum Crystals by Paul’s Lab on Flickr
This is a photo of chrome alum crystals in a chrome alum solution, at 20x magnification. Taken with my Canon SX110 IS, through a Novex stereo microscope with lighting from underneath. The crystals are grown from a saturated solution and are no more than 1 mm in diameter. Created myself, Paul, from www.paulslab.com
Funaria hygrometrica peristome by gjshepherd_br
This is a scanning electron microscope image of the peristome of a Funaria hygrometrica capsule. In this case, the outer peristome teeth are attached to the central disc (rare), and as they elongate or shrink with changes in humidity, the whole structures twists, opening up in dry weather and closing when it’s humid. Like other mosses, peristome tooth formation in Funaria is quite complex and their structure is rich in small details.
Snowflakes are not frozen raindrops (that is better known as sleet). They form when water vapor condenses directly into ice, which happens in the clouds. In their most basic form, snow crystals are hexagonal prisms, and other more complex forms are famously possible.
E. coli bacteria, SEM
E. coli bacteria, coloured scanning electron micrograph (SEM). Escherichia coli are Gram-negative rod-shaped bacteria that are part of the normal flora of the human gut. Some strains produce a toxin that causes severe diarrhoea and can be fatal, especially in the very young or elderly. Magnification: x6,500 when printed at 10 centimetres wide.
