Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [ 1] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ...
Mechanical pressing of glass reduced the time and labor necessary to make glass products, which lowered costs and made glass products available to more of the public. An 1884 U.S. government report considered mechanical pressing and a new formula for glass to be the two great advances in American glassmaking during the 19th century. [25]
Von Kleist happened to hold, near his electric machine, a small bottle, in the neck of which there was an iron nail. Touching the iron nail accidentally with his other hand he received a severe electric shock. In much the same way Musschenbroeck assisted by Cunaens received a more severe shock from a somewhat similar glass bottle.
The history of glass-making dates back to at least 3,600 years ago in Mesopotamia. However, most writers claim that they may have been producing copies of glass objects from Egypt. [ 1] Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt. [ 2]
The history of fluid mechanics is a fundamental strand of the history of physics and engineering. The study of the movement of fluids (liquids and gases) and the forces that act upon them dates back to pre-history. The field has undergone a continuous evolution, driven by human dependence on water, meteorological conditions and internal ...
Although glass was made at Jamestown, production was soon suspended because of strife in the colony. A second attempt at Jamestown also failed. Later attempts to produce glass were made during the 1600s; glass works in New Amsterdam and the Colony of Massachusetts Bay had some success. In the 17th century, at least two New Amsterdam glass ...
