Institute For Energy Technology
Institute for Energy Technology (IFE) was established in 1948 as the Institute for Nuclear Energy (IFA). The name was changed in 1980. Its main office is at Kjeller, Norway, and slightly under half of the institute’s activities are based in Halden. In Halden IFE is host to the international OECD Halden Reactor Project, with 18 member states. IFE conducts research in the following areas: energy, environmental technology, physics, materials science, petroleum technology, nuclear safety and reliability and man-machine systems (man-technology-organisation). IFE operates the only two existing nuclear reactors in Norway. Both are dedicated to research. The JEEP II reactor at Kjeller is used for basic research in physics and material science, as well as production of radiopharmaceuticals. The Halden Reactor is used for research in materials technology and nuclear fuel safety. The Institute has approximately 600 employees in Halden and at Kjeller. The President is Nils Morten Hus ...

JEEP II
JEEP II was a research reactor in Kjeller, Norway that was in operation between 1966 and 2018. The reactor was operated by the Institute for Energy Technology (IFE). Construction of JEEP II began in 1965, and the reactor went critical for the first time in December 1966. The reactor had a thermal power of 2 MW. It used heavy water as a moderator and coolant, and used low-enriched uranium Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (23 ... as fuel. JEEP II was used for basic research in solid state physics, neutron irradiation of materials and production of radioactive isotopes. The reactor was stopped on December 15, 2018 for scheduled maintenance, whereby major damage was discovered. This meant that IFE's board decided on 25 April 2019 not to restart the reactor but instead to sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odd Dahl
Odd Dahl (3 November 1898 – 2 June 1994) was a Norwegian engineer and explorer. He is particularly remembered for his contributions to research in nuclear physics. Biography He was born at Drammen in Buskerud, Norway, the son of businessman Lauritz Dahl (1858-1932) and his wife Olga Sørensen. Dahl attended an evening technical school during his teenage years. In 1917, he was employed by Fenger Hagen, an electrical engineer with an interest in radio telephony. In 1921, Dahl was admitted as a student at the Army Flyvevæsens flight school at Kjeller in Skedsmo where he received an international pilot's license. Roald Amundsen hired him in 1922 as a pilot, mechanic, radio operator and cinematographer on an expedition in the Arctic Ocean in an effort to fly over the North Pole. After three test flights, the plane was wrecked in flight. However, Odd Dahl's research work made the expedition considered successful.

O Estado De S
O, or o, is the fifteenth letter and the fourth vowel letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''o'' (pronounced ), plural ''oes''. History Its graphic form has remained fairly constant from Phoenician times until today. The name of the Phoenician letter was '' ʿeyn'', meaning "eye", and indeed its shape originates simply as a drawing of a human eye (possibly inspired by the corresponding Egyptian hieroglyph, cf. Proto-Sinaitic script). Its original sound value was that of a consonant, probably , the sound represented by the cognate Arabic letter ع ''ʿayn''. The use of this Phoenician letter for a vowel sound is due to the early Greek alphabets, which adopted the letter as O "omicron" to represent the vowel . The letter was adopted with this value in the Old Italic alphabets, including the early Latin alphabet. In Greek, a variation of the for ...

Solar Cell Research
There are currently many research groups active in the field of photovoltaics in universities and research institutions around the world. This research can be categorized into three areas: making current technology solar cells cheaper and/or more efficient to effectively compete with other energy sources; developing new technologies based on new solar cell architectural designs; and developing new materials to serve as more efficient energy converters from light energy into electric current or light absorbers and charge carriers. Silicon processing One way of reducing the cost is to develop cheaper methods of obtaining silicon that is sufficiently pure. Silicon is a very common element, but is normally bound in silica, or silica sand. Processing silica (SiO2) to produce silicon is a very high energy process - at current efficiencies, it takes one to two years for a conventional solar cell to generate as much energy as was used to make the silicon it contains. More energy efficie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Corrosion Inhibition
In chemistry, a corrosion inhibitor or anti-corrosive is a chemical compound that, when added to a liquid or gas, decreases the corrosion rate of a material, typically a metal or an alloy, that comes into contact with the fluid. The effectiveness of a corrosion inhibitor depends on fluid composition, quantity of water, and flow regime. Corrosion inhibitors are common in industry, and also found in over-the-counter products, typically in spray form in combination with a lubricant and sometimes a penetrating oil. They may be added to water to prevent leaching of lead or copper from pipes. A common mechanism for inhibiting corrosion involves formation of a coating, often a passivation layer, which prevents access of the corrosive substance to the metal. Permanent treatments such as chrome plating are not generally considered inhibitors, however: corrosion inhibitors are additives to the fluids that surround the metal or related object. Types The nature of the corrosive inhibitor de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Renewable Energy
Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Energy
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy (including solar water heating), and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air. The large magnitude of solar energy available makes it a highly appealing source of electricity. In 2020 solar energy has been the cheapest source of Electricity.

Hydrogen Storage
Hydrogen storage can be accomplished by several existing methods of holding hydrogen for later use. These include mechanical approaches such as using high pressures and low temperatures, or employing chemical compounds that release H2 upon demand. While large amounts of hydrogen are produced by various industries, it is mostly consumed at the site of production, notably for the synthesis of ammonia. For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. Interest in using hydrogen for on-board storage of energy in zero-emissions vehicles is motivating the development of new methods of storage, more adapted to this new application. The overarching challenge is the very low boiling point of H2: it boils around 20.268 K (−252.882 °C or −423.188 °F). Achieving such low temperatures requires expending significant energy. Es ...
