Devices and methods for styling hair, and in particular, to devices and methods for styling hair using electrolysis are described herein. A method for styling hair includes arranging a section of hair between a first electrode and a second electrode. The section of hair is contacted with an electrolyte before being arranged between the first and second electrodes, after being arranged between the first and second electrodes, and/or concurrently with being arranged between the first and second electrodes. The method further includes causing the first electrode to have a first negative potential, and causing the second electrode to have a second potential, such that the absolute value of the first negative potential is greater than the absolute value of the second potential, and such that the difference in electrical potential between the first electrode and the second electrode creates an electrolysis zone between the first electrode and the second electrode.

A method for producing one or more hydroxide solids includes providing a catholyte comprising an electrolyte solution; contacting the catholyte with an electroactive mesh cathode to electrolytically generate hydroxide ions, thereby precipitating the one or more hydroxide solid(s); and removing the one or more hydroxide solids from the surface of the mesh where they may deposit.

The invention relates to a method, a device and a system for producing particularly a hydrogel (200) and for controlling an enzymatically catalyzed formation of a covalent bond in a solution, wherein said covalent bond is formed between a first compound (20) comprising a first moiety (21) and a second compound (22) comprising a second moiety (23), wherein the first and the second moiety (21, 23) are a substrate of an enzyme wherein said enzyme catalyzes the formation of a covalent bond between the first and the second moiety (21, 23), and wherein a voltage is applied to the solution for spatially controlling said formation, wherein said voltage is adjusted such that it induces electrolysis of said solution.

An environment control system utilizes oxygen and humidity control devices that are coupled with an enclosure to independently control the oxygen concentration and the humidity level within the enclosure. An oxygen depletion device may be an oxygen depletion electrolyzer cell that reacts with oxygen within the cell and produces water through electrochemical reactions. A desiccatting device may be g, a dehumidification electrolyzer cell, a desiccator, a membrane desiccator or a condenser. A controller may control the amount of voltage and/or current provided to the oxygen depletion electrolyzer cell and therefore the rate of oxygen reduction and may control the amount voltage and or current provided to the dehumidification electrolyzer cell and therefore the rate of humidity reduction. The oxygen level may be determined by the measurement of voltage and a limiting current of the oxygen depletion electrolyzer cell. The enclosure may be a food or artifact enclosure.
