He also invented a curling iron, an apparatus for demagnetising watches, magno-electric machines, devices to prevent the rolling of ships, eyelet and riveting machines, aircraft artillery, an aerial torpedo gun, coffee substitutes, and various oil, steam, and gas engines.
Pourbaix diagram of iron. [1] The Y axis corresponds to voltage potential. In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H –pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system.
Kirlian photograph of two coins. Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges.It is named after Soviet scientist Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate.

An electric curling iron A manual, 1920s curling iron. Curling irons, also known as curling tongs, create waves or curls in hair using a variety of different methods.There are many different types of modern curling irons, which can vary by diameter, material, and shape of barrel and the type of handle.
The hot petrolatum used with the iron was thought to cause a chronic inflammation around the upper segment of the hair follicle leading to degeneration of the external root sheath. [ 21 ] In 1992, a hot comb alopecia study was conducted, and it was discovered that there was a poor correlation between the usage of a hot comb and the onset and ...
Icall developed what was called the "wireless" system, in which the electric lead to the heater was replaced by a cord that took the weight of the heater, and the heater was heated by plugging into a socket in the chandelier. Outwardly, the machine looked similar to the earlier model, but at no time was there an electric potential near the head.
From 2020 to 2021, researchers found, the number of children and teens injured on electric scooters rose 71% in the U.S. Emergency departments reported more than 13,500 such injuries over the two ...
There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong nuclear force or weak nuclear force acting on the baryon charge is ...
