The glass globes, known as "electerizing globes", [29] were made of glass that was scientifically designed to produce static electricity effectively. [30] Franklin specified the materials to be used in the glass formula, and the globes were manufactured by Caspar Wistar , a close associate of Franklin. [ 13 ]
Decoupage or découpage ( / ˌdeɪkuːˈpɑːʒ /; [ 1] French: [dekupaʒ]) is the art of decorating an object by gluing colored paper cutouts onto it in combination with special paint effects, gold leaf, and other decorative elements. Commonly, an object like a small box or an item of furniture is covered by cutouts from magazines or from ...
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 ...
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 ...
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]
1968 – Liquid crystal display developed by RCA. 1970 – Silica optical fibers grown by Corning Incorporated. 1980 – Duplex stainless steels developed which resist oxidation in chlorides. 1984 – Fold-forming system developed by Charles Lewton-Brain to produce complex three dimensional forms rapidly from sheet metal.
History of materials science. Materials science has shaped the development of civilizations since the dawn of humankind. Better materials for tools and weapons has allowed people to spread and conquer, and advancements in material processing like steel and aluminum production continue to impact society today. Historians have regarded materials ...
t. e. Domes built in the 19th, 20th, and 21st centuries benefited from more efficient techniques for producing iron and steel as well as advances in structural analysis. Metal-framed domes of the 19th century often imitated earlier masonry dome designs in a variety of styles, especially in church architecture, but were also used to create glass ...
