Ångström Laboratory
The Ångström Laboratory ( Swedish: ''Ångströmslaboratoriet'') is a facility of Uppsala University. It hosts multiple research laboratories and departments of mathematics, computer science, natural science and engineering. History The facility is named after Swedish physicist Anders Jonas Ångström and his son Knut Ångström, both of whom were professors at Uppsala University in the 19th century. It was first inaugurated in 1997, at , next to a site that historically served the purpose of training the Uppland Regiment from 1680–1912. This site later evolved to house the university's Information Technology Centre (ITC). Ångström was erected south-west of the regiment site, initially primarily to accommodate a cleanroom. This first construction is referred to as stage 1, including buildings 1, 2, 3, 4, 5. In year 2000, stage 2 was realized, including buildings 6 and 8. Building 7 was realized in 2006, and in 2013 the FREIA laboratory was constructed between buildings 5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uppsala
Uppsala ( ; ; archaically spelled ''Upsala'') is the capital of Uppsala County and the List of urban areas in Sweden by population, fourth-largest city in Sweden, after Stockholm, Gothenburg, and Malmö. It had 177,074 inhabitants in 2019. Located north of the capital Stockholm, it is also the seat of Uppsala Municipality. Since 1164, Uppsala has been the ecclesiology, ecclesiastical centre of Sweden, being the seat of the Archbishop of Uppsala, Archbishop of the Church of Sweden. Uppsala is home to Scandinavia's largest cathedral – Uppsala Cathedral, which was the frequent site of the coronation of the Swedish monarch until the late 19th century. Uppsala Castle, built by King Gustav I of Sweden, Gustav Vasa, served as one of the royal residences of the Swedish monarchs, and was expanded several times over its history, making Uppsala the secondary capital of Sweden during its Swedish Empire, greatest extent. Today, it serves as the residence of the Governor of Uppsala County ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State-owned Enterprise
A state-owned enterprise (SOE) is a business entity created or owned by a national or local government, either through an executive order or legislation. SOEs aim to generate profit for the government, prevent private sector monopolies, provide goods at lower prices, implement government policies, or serve remote areas where private businesses are scarce. The government typically holds full or majority ownership and oversees operations. SOEs have a distinct legal structure, with financial and developmental goals, like making services more accessible while earning profit (such as a state railway). They can be considered as government-affiliated entities designed to meet commercial and state capitalist objectives. Terminology The terminology around the term state-owned enterprise is murky. All three words in the term are challenged and subject to interpretation. First, it is debatable what the term "state" implies (e.g., it is unclear whether municipally owned corporations and ente ...

Carolina Rediviva
Carolina Rediviva is a part of Uppsala University Library in Uppsala, Sweden. The building was begun in 1820 and completed in 1841. The original architect was Carl Fredrik Sundvall. Later additions to the building have been designed by Axel Johan Anderberg and Peter Celsing. The name, literally "Carolina Revived", was given in remembrance of the old ''Academia Carolina'' building, which had functioned as the university library for most of the 18th century (see Uppsala University Library). Carolina Rediviva is the oldest and largest university library building in the country. It is also the site where the ''Codex Argenteus'' and the Cancionero de Upsala are kept. Exhibition By the entrance hall of the library there is an exhibition hall where some of the most important objects in the library can be seen. Among the items are the ''Codex Argenteus The (Latin for "Silver Book/Codex") is a 6th century, 6th-century illuminated manuscript, originally containing Gospel#Can ...

Gustavianum
Gustavianum is the oldest standing building of Uppsala University. It was built between 1622 and 1625, and was used as the main building of the university between 1778 and 1887. Since 1997, it has been used as the university's museum. History During the 16th century, Uppsala University was in decline, and by the latter part of the century tutoring had stopped almost entirely. During Uppsala Synod in 1593, however, there was an official decision to re-open the university. Due to the increasing number of students, the medieval university building was no longer able to house the entire university; therefore, a second university structure became necessary. Gustavianum was built between 1622 and 1625. The name ''Gustavianum'' comes from Gustavus Adolphus, who in the 1620s donated money for its construction. The building was designed by the Dutch architect and contained lecture halls, printing halls and housing for gifted students without means. In 1662, the professor of medicine an ...

The Svedberg Laboratory
The Svedberg Laboratory (TSL) is a university facility, based in Uppsala, Sweden. It is under Decommission since 2016. The activities at TSL were based around the particle accelerator ''Gustaf Werner cyclotron''. The main activity was proton therapy for the treatment of cancer, based on an agreement between the Oncology clinic at Uppsala University Hospital and Uppsala University. Beamtime not used for proton therapy was devoted to commercial neutron and proton irradiation projects, mainly for Radiation testing. There was also some time for basic (academic) research and in this case the experiments should be associated to Uppsala University or to EC projects. TSL was supported by the European Community and belonged to the EC projects ERINDA, SkyFlash and CHANDA. History Theodor Svedberg (1884–1971), professor in physical chemistry at Uppsala University from 1912 to 1949, was awarded the Nobel Prize in chemistry in 1926 for his research on dispersed systems (colloidal soluti ...

Photochromic
Photochromism is the reversible change of color upon exposure to light. It is a transformation of a chemical species (photoswitch) between two forms through the absorption of electromagnetic radiation (photoisomerization), where each form has a different absorption spectrum. This reversible structural or geometric change in photochromic molecules affects their electronic configuration, molecular strain energy, and other properties. History In 1867, Carl Julius Fritzsche reported the concept of photochromism, indicating that orange tetracene solution lost its color in daylight but regained it in darkness. Later, similar behavior was observed by both Edmund ter Meer and Phipson. Ter Meer documented the color change of the potassium salt of dinitroethane, which appeared red in daylight and yellow in the dark. Phipson also recorded that a painted gatepost appeared black during the day and white at night due to a zinc pigment, likely lithopone. In 1899, Willy Marckwald, Willy Markwald, ...

Vertical-axis Wind Turbine
A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which removes the need for wind-sensing and orientation mechanisms. Major drawbacks for the early designs (Savonius, Darrieus and giromill) included the significant torque ripple during each revolution and the large bending moments on the blades. Later designs addressed the torque ripple by sweeping the blades helically ( Gorlov type). Savonius vertical-axis wind turbines (VAWT) are not widespread, but their simplicity and better performance in disturbed flow-fields, compared to small horizontal-axis wind turbines (HAWT) make them a good alternative for distributed generation devices in an urban environment. A vertical axis wind t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upsalite
Mesoporous magnesium carbonates (MMCs) constitute a family of magnesium carbonate materials with high specific surface areas. It was first reported in July 2013 by a group of researchers in nanotechnology at Uppsala University.Forsgren J, Frykstrand S, Grandfield K, et al. A template-free, ultra-adsorbing, high surface area carbonate nanostructure. ''PLoS One'' 8, e68486 (2013). The highest reported surface area of any MMC is 800 m² per gram, which is the highest surface area ever measured for an alkali earth metal carbonate. The average pore size of MMCs can be adjusted by tuning the synthesis conditions.Cheung O, Zhang P, Frykstrand, S, et al. Nanostructure and pore size control of template-free synthesised mesoporous magnesium carbonate. ''RSC Advances'' 6, 74241–74249 (2016). So far, all reported forms of MMCs are anhydrous and Amorphous solid, amorphous. As with other types of mesoporous materials, the large surface area and the nanometer sized pores make MMCs interesting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
