Synapse, SEM Featured Print

Synapse, SEM

Synapse. Scanning electron micrograph (SEM) of a neuromuscular junction showing a motor neurone (vertical line) terminating on skeletal muscle fibres (across bottom frame). The axon of a motor neurone terminates in several branching fibres, each of which ends in an end plate, a cluster of small swellings, or boutons. When activated, the boutons release neurotransmitter chemicals from small vesicles. The neurotransmitters diffuse across the gap, or synaptic cleft, separating the axon and muscle and bind with receptors in the muscle cell. Magnification: x940 when printed at 10 centimetres tall.


Early electric motor, 1834 Featured Print

Early electric motor, 1834

Early electric motor. Historical artwork of one of the first full-scale, practical electric motors, one of several designed and built from 1834 by the German physicist and engineer Moritz von Jacobi (1801-1874). The principle of the electric motor had been demonstrated by Michael Faraday in 1821. Jacobi moved to St Petersburg, Russia, in 1837. In 1839, financed by Tsar Nicholas I, he built a boat that used electric batteries to power an electric motor to drive paddlewheels. A similar arrangement is seen here, with wires (bottom) connecting to the batteries, and eight solenoids (wires coiled around cylinders) acting as electromagnets to turn wheels on the central shaft. Artwork from A Travers l'Electricite (G. Dary, Paris, 1900).


Zenobe Gramme Featured Print

Zenobe Gramme

Zenobe Gramme (1826-1901), Belgian electrical engineer in his workshop. Gramme was interested in improving the efficiency of electrical devices. In 1710 he demonstrated the Gramme machine, a continuous-current generator that produced large currents in relation to its size. At an exhibition in Vienna, Austria, a technician wired a series of such machines together incorrectly, so that the wires from one which was running were joined to one which was not. To the amazement of the onlookers, the second machine began to turn: the Gramme machine could act as both a generator and a motor. This allowed the possibility for work to be transferred large distances via electricity. Taken from Physique Populaire, 1891.
