Moissan isolating fluorine, 1886 Featured 21 Mar 2005 Print

Moissan isolating fluorine, 1886

Moissan isolating fluorine. Historical artwork of the French chemist Henri Moissan (1852-1907) isolating fluorine in 1886. The electrolysis set-up at right centres on a beaker containing a U-tube in a cooling liquid (at minus 23 degrees Celsius). The U-tube contains a solution of potassium fluoride (provides electrical conductivity) in hydrofluoric acid. The electrical wires connect to electrodes (iridium/platinum) dipped inside the U-tube. Side tubes allow collection of the products (hydrogen gas, right; fluorine gas [yellow], left). Moissan was awarded the 1906 Nobel Prize for Chemistry for his work on fluorine and electric arc furnaces. From Physique Populaire (E. Desbeaux, 1891)

Sporangium of bread mould, Rhizopus Featured 21 Mar 2005 Print

Sporangium of bread mould, Rhizopus

False colour scanning electron micrograph of a sporangium, or fruiting body, of the common bread mould, Rhizopus stolonifer. Spores circulate freely in the air. When they alight on a favourable medium, they germinate a network of hyphae (threads). Their function is to absorb food for growth & for spore production. Rhizopus produces stolons, or aerial hyphae, which on contact with a medium grow rhizoids or "rootlets". They anchor the fungus & absorb some water. Spores develop in saclike bodies, or sporangia. Under pressure from the maturing spores, the wall fragments, releasing the spores for dispersal. Magnification: X 71 at 35mm size
