Mansfield College, Oxford
Mansfield College, Oxford is one of the Colleges of the University of Oxford, constituent colleges of the University of Oxford in Oxford, England. The college was founded in Birmingham in 1838 as a college for Nonconformist (Protestantism), Nonconformist students. It moved to Oxford in 1886 and was renamed Mansfield College after George Mansfield and his sister Elizabeth. In 1995 a royal charter was awarded giving the institution full college status. The college grounds are located on Mansfield Road, near the centre of Oxford. As of February 2018, the college comprises 231 undergraduates, 158 graduates, 34 visiting students and 67 fellows and academics. The principal of the college since 2018 is Helen Mountfield, a barrister and legal scholar. History The college was founded in 1838, under the patronage of George Storer Mansfield (1764–1837) and his two sisters Sarah (1767–1853) and Elizabeth (1772–1847), as Spring Hill College, Birmingham, a college for Nonconformist ...

Nuclear Physics
Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions, in addition to the study of other forms of nuclear matter. Nuclear physics should not be confused with atomic physics, which studies the atom as a whole, including its electrons. Discoveries in nuclear physics have led to applications in many fields. This includes nuclear power, nuclear weapons, nuclear medicine and magnetic resonance imaging, industrial and agricultural isotopes, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Such applications are studied in the field of nuclear engineering. Particle physics evolved out of nuclear physics and the two fields are typically taught in close association. Nuclear astrophysics, the application of nuclear physics to astrophysics, is crucial in explaining the inner workings of stars and the origin of the chemical elements.

Linacre College, Oxford
Linacre College is a constituent college of the University of Oxford in the UK whose members comprise approximately 50 fellows and 550 postgraduate students. Linacre is a diverse college in terms of both the international composition of its members (the majority of whom are from outside the UK and represent 133 countries), as well as the disciplines studied. Linacre was the first graduate college in the UK for both sexes and all subjects. Unlike most colleges, students and fellows share the same common room and there is no high table. The college is named after Thomas Linacre (1460–1524), founder of the Royal College of Physicians as well as a distinguished renaissance humanist — multidisciplinary interests that the college aims to reflect. The college is located on St Cross Road at its junction with South Parks Road, bordering University Parks to the north and the University Science Area to the west. History Linacre College (called Linacre House for its first three yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clare College, Cambridge
Clare College is a constituent college of the University of Cambridge in Cambridge, England. The college was founded in 1326 as University Hall, making it the second-oldest surviving college of the University after Peterhouse. It was refounded in 1338 as ''Clare Hall'' by an endowment from Elizabeth de Clare, and took on its current name in 1856. Clare is famous for its chapel choir and for its gardens on "The Backs" (the back of the colleges that overlook the River Cam). Clare is consistently one of the most popular Cambridge colleges amongst prospective applicants. History The college was founded in 1326 by the university's Chancellor, Richard Badew, and was originally named ''University Hall''. Providing maintenance for only two fellows, it soon hit financial hardship. In 1338, the college was refounded as ''Clare Hall'' by an endowment from Elizabeth de Clare, a granddaughter of Edward I, which provided for twenty fellows and ten students.

Natural Sciences (Cambridge)
The Natural Sciences Tripos (NST) is the framework within which most of the science at the University of Cambridge is taught. The tripos includes a wide range of Natural Sciences from physics, astronomy, and geoscience, to chemistry and biology, which are taught alongside the history and philosophy of science. The tripos covers several courses which form the University of Cambridge system of Tripos. It is known for its broad range of study in the first year, in which students cannot study just one discipline, but instead must choose three courses in different areas of the natural sciences and one in mathematics. As is traditional at Cambridge, the degree awarded after Part II (three years of study) is a Bachelor of Arts (BA). A Master of Natural Sciences degree (MSci) is available to those who take the optional Part III (one further year). It was started in the 19th Century. Teaching Teaching is carried out by 16 different departments. Subjects offered in Part IA in 2019 are Biol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Graphite
Nuclear graphite is any grade of graphite, usually synthetic graphite, manufactured for use as a moderator or reflector within a nuclear reactor. Graphite is an important material for the construction of both historical and modern nuclear reactors, due to its extreme purity and ability to withstand extremely high temperature. Graphite has also recently been used in nuclear fusion reactors such as the Wendelstein 7-X. As of experiments published in 2019, graphite in elements of the stellarator's wall and a graphite island divertor have greatly improved plasma performance within the device, yielding better control over impurity and heat exhaust, and long high-density discharges. History Nuclear fission, the creation of a nuclear chain reaction in uranium, was discovered in 1939 following experiments by Otto Hahn and Fritz Strassman, and the interpretation of their results by physicists such as Lise Meitner and Otto Frisch. Shortly thereafter, word of the discovery spread thro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceramic Matrix Composite
In materials science, ceramic matrix composites (CMCs) are a subgroup of composite materials and a subgroup of ceramics. They consist of ceramic fibers embedded in a ceramic matrix. The fibers and the matrix both can consist of any ceramic material, whereby carbon and carbon fibers can also be regarded as a ceramic material. Introduction The motivation to develop CMCs was to overcome the problems associated with the conventional technical ceramics like alumina, silicon carbide, aluminum nitride, silicon nitride or zirconia – they fracture easily under mechanical or thermo-mechanical loads because of cracks initiated by small defects or scratches. The crack resistance is very low, as in glass. To increase the crack resistance or fracture toughness, particles (so-called monocrystalline ''whiskers'' or ''platelets'') were embedded into the matrix. However, the improvement was limited, and the products have found application only in some ceramic cutting tools. So far only the i ...

Micromechanics
Micromechanics (or, more precisely, micromechanics of materials) is the analysis of composite or heterogeneous materials on the level of the individual constituents that constitute these materials. Aims of micromechanics of materials Heterogeneous materials, such as composites, solid foams, polycrystals, or bone, consist of clearly distinguishable constituents (or ''phases'') that show different mechanical and physical material properties. While the constituents can often be modeled as having isotropic behaviour, the microstructure characteristics (shape, orientation, varying volume fraction, ..) of heterogeneous materials often leads to an anisotropic behaviour. Anisotropic material models are available for linear elasticity. In the nonlinear regime, the modeling is often restricted to orthotropic material models which does not capture the physics for all heterogeneous materials. Micromechanics goal is to predict the anisotropic response of the heterogeneous material on the b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
