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 ]
Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension .
The battery's design is safer than lithium-ion batteries, as the use of a flammable liquid electrolyte is avoided. [2] The battery can also be made using low-cost sodium instead of lithium. [2] The authors claim the battery has a much shorter charging time than Li-ion batteries—in minutes rather than hours.
The experiment consists of two brass bells, each positioned beneath a dry pile (a form of battery), the pair of piles connected in series, giving the bells opposite electric charges. The clapper is a metal sphere approximately 4 mm (3 ⁄ 16 in) in diameter suspended between the piles, which rings the bells alternately due to electrostatic ...
In the 1700s American statesman and scientist Benjamin Franklin performed extensive investigations of both water-filled and foil Leyden jars, which led him to conclude that the charge was stored in the glass, not in the water. A popular experiment, due to Franklin, which seems to demonstrate this involves taking a jar apart after it has been ...
In his experiment, Faraday closed the opening by attaching the metal lid of the pail to the thread suspending the ball, so when the ball was lowered to the center of the container the lid covered the opening. [1] [3] However this is not necessary. The experiment works very well even for containers with large uncovered openings, like Faraday's pail.
The pH electrode is an example of a glass electrode that is sensitive to hydrogen ions. Glass electrodes play an important part in the instrumentation for chemical analysis, and physicochemical studies. The voltage of the glass electrode, relative to some reference value, is sensitive to changes in the activity of a certain type of ions.
The electrochemical window (EW) is an important concept in organic electrosynthesis and design of batteries, especially organic batteries. [5] This is because at higher voltage (greater than 4.0 V) organic electrolytes decompose and interferes with the oxidation and reduction of the organic cathode/anode materials.
