Energy Storage
Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an Accumulator (energy), accumulator or Battery (electricity), battery. Energy comes in multiple forms including radiation, chemical energy, chemical, gravitational potential energy, gravitational potential, Electric potential energy, electrical potential, electricity, elevated temperature, latent heat and kinetic energy, kinetic. Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms. Some technologies provide short-term energy storage, while others can endure for much longer. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped. Grid energy storage is a collection of methods used for energy storage on a large scale within an electrical power grid. Common e ...

Redox
Redox ( , , reduction–oxidation or oxidation–reduction) is a type of chemical reaction in which the oxidation states of the reactants change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. The oxidation and reduction processes occur simultaneously in the chemical reaction. There are two classes of redox reactions: * Electron transfer, Electron-transfer – Only one (usually) electron flows from the atom, ion, or molecule being oxidized to the atom, ion, or molecule that is reduced. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * Atom transfer – An atom transfers from one Substrate (chemistry), substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously, the oxidation state of oxygen decreases as it accepts electrons r ...

Fuel Cell
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen fuel, hydrogen) and an oxidizing agent (often oxygen) into electricity through a pair of redox reactions. Fuel cells are different from most battery (electricity), batteries in requiring a continuous source of fuel and oxygen (usually from air) to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. The first fuel cells were invented by Sir William Robert Grove, William Grove in 1838. The first commercial use of fuel cells came almost a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932. The alkaline fuel cell, also known as the Bacon fuel cell after its inventor, has been used in NASA space programs since the mid-1960s to generate power for sate ...

Adjuntas, Puerto Rico
Adjuntas () is a small mountainside town and municipality in Puerto Rico located in the central midwestern portion of the island on the Cordillera Central, north of Yauco, Guayanilla, and Peñuelas; southeast of Utuado; east of Lares and Yauco; and northwest of Ponce. Adjuntas is spread over 16 ''barrios'' and Adjuntas Pueblo (the downtown area and the administrative center of the city). Adjuntas is about two hours by car westward from the capital, San Juan. Adjuntas is nicknamed "the Switzerland of Puerto Rico" because of its relatively chilly weather. Many Puerto Rican mountain towns have cooler weather than the rest of the island; Adjuntas is no exception: the average yearly weather is 70 °F (21 °C) (High: 83 °F/28 °C; Low: 58 °F/14 °C). Puerto Rico's lowest temperature were recorded in Adjuntas at 38 °F in 2018. Its mild climate attracts a good number of island tourists during the summer months. The town has a small hotel n ...

Gordon Research Conferences
Gordon Research Conferences are a group of international scientific conferences organized by a non-profit organization of the same name, since 1931 covering frontier research in the chemical, and physical and later biological, sciences, and their related technologies. The conferences have been held in the US since 1931, and have expanded to almost 400 conferences per year since 1990, including Europe and Asia. Conference locations are chosen partly for their scenic and often isolated nature, to encourage an informal community atmosphere. Contributions are off the record, with references to the conference in any publication strictly prohibited to encourage free discussion, often of unpublished research. In 1991, conferences were extended to cover science education. History The Gordon Research Conferences (GRC) were initiated by Neil Gordon while at Johns Hopkins University. The forerunner of the conferences were the summer sessions held at the chemistry department in the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
