Unit cell of Laves phase with MgZn2 structure (Mg atoms are green). Laves polyhedron Laves phases are intermetallic phases that have composition AB2 and are named for Fritz Laves who first described them. The phases are classified on the basis of geometry alone. While the problem of packing spheres of equal size has been well-studied since Gauss, Laves phases are the result of his investigations into packing spheres of two sizes. Laves phases fall into three Strukturbericht types: cubic MgCu2 (C15), hexagonal MgZn2 (C14), and hexagonal MgNi2 (C36).

Fritz Henning Emil Paul Berndt Laves (27 February 1906 – 12 August 1978) was a German crystallographer who served as the president of the German Mineralogical Society from 1956 to 1958. He is the namesake of Laves phases and the Laves tilings; the Laves graph, a highly-symmetrical three-dimensional crystal structure that he studied, was named after him by H. S. M. Coxeter...

In the 1987 book, Tilings and Patterns, Branko Grünbaum calls the vertex-uniform tilings Archimedean in parallel to the Archimedean solids. Their dual tilings are called Laves tilings in honor of crystallographer Fritz Laves. They're also called Shubnikov–Laves tilings after Shubnikov, Alekseĭ Vasilʹevich.Encyclopaedia of Mathematics: Orbit - Rayleigh Equation , 1991 John Conway calls the uniform duals Catalan tilings, in parallel to the Catalan solid polyhedra.

Laves was the editor of the journal Zeitschrift für Kristallographie between 1955 and 1978, which honoured him with a special issue in May 2006 commemorating the hundredth anniversary of his birth. The issue was devoted to the crystal chemistry of intermetallic compounds and included two articles on Laves' contributions to crystallography. Laves was married to architect Melitta Druckenmüller, who assisted him with many of the illustrations in his publications.

Accessed on 2009-2-26. Laves phases are of particular interest in modern metallurgy research because of their abnormal physical and chemical properties. Many hypothetical or primitive applications have been developed. However, little practical knowledge has been elucidated from Laves phase study so far.

The Laves tilings have vertices at the centers of the regular polygons, and edges connecting centers of regular polygons that share an edge. The tiles of the Laves tilings are called planigons. This includes the 3 regular tiles (triangle, square and hexagon) and 8 irregular ones. Each vertex has edges evenly spaced around it.

The Laves graph In geometry and crystallography, the Laves graph is an infinite cubic symmetric graph. It can be embedded into three-dimensional space, with integer coordinates, to form a structure with chiral symmetry. . in which the three edges at each vertex form 120° angles to each other. It can also be defined more abstractly as a covering graph of the complete graph on four vertices.

Gerhardt Laves (July 15, 1906 – March 14, 1993) was a graduate student at the University of Chicago and Yale University who between August 1929 and August 1931 undertook extensive fieldwork on Australian Aboriginal languages. Laves was probably the first person trained in modern linguistic fieldwork and analysis to study Australian languages. He intensively studied six languages: 'Kumbaingeri' (Gumbaynggir) in northern New South Wales; 'Karadjeri' (Karajarri) at Lagrange Bay, north-west Western Australia; 'Barda' (Bardi) at Cape Leveque, north-west Western Australia; 'Kurin' (Goreng) near Albany Western Australia; and 'Hermit Hill' (Matngele) and 'Ngengumeri (Ngan'gimerri) at Daly River Northern Territory. On the basis of his work Laves concluded that all Australian languages belong to a single language family.

Laves was born in Hanover, the son of a judge and a descendant of architect Georg Ludwig Friedrich Laves. He grew up in Göttingen, where his interests included piano music as well as collecting rocks and minerals. He began his university studies in geology in 1924 at the University of Innsbruck, and continued at the University of Göttingen before moving to ETH Zurich for doctoral studies under Paul Niggli. In 1929 he took a faculty position under Victor Goldschmidt at Göttingen.

The regular skew polyhedron onto which the Laves graph can be inscribed As describes, the vertices of the Laves graph can be defined by selecting one out of every eight points in the three- dimensional integer lattice, and forming their nearest neighbor graph. Specifically, one chooses the points :(0,0,0),\quad (1,2,3),\quad (2,3,1),\quad (3,1,2), :(2,2,2),\quad (3,0,1),\quad (0,1,3),\quad (1,3,0), and all the other points that can be formed by adding multiples of four to these coordinates. The edges of the Laves graph connect pairs of points whose Euclidean distance from each other is (these pairs differ by one unit in two coordinates, and are the same in the third coordinate). The other non-adjacent pairs of vertices are farther apart, at a distance of at least from each other.

Computations suggest that the Laves graph can serve as the pattern for a metastable or perhaps unstable allotrope of carbon... Like graphite, each atom in the structure is bonded to three others, but in graphite adjacent atoms have the same bonding planes as each other whereas in this structure the bonding planes of adjacent atoms are twisted with respect to each other around the line formed by the bond, with a twisting angle of approximately 70.5°. The Laves graph may also give a crystal structure for boron; computations predict that this should be stable. Other chemicals that may form this structure include SrSi2, and elemental nitrogen..

When she finds one living midst the wounded Then she laves him with the cooling water, Gives him, sacramentally, the red wine, Pledges with her fair white bread the hero. Fate at last has led her wand'ring footsteps Unto Pavle Orlović, the hero, Who has borne the Prince's battle-standard. From his gaping wounds the blood is streaming, His right hand and his left foot are severed; And the hero's ribs are crushed and broken, But he lingers still amongst the living. From the pools of blood she drags his body And she laves him with the cooling water, Red wine, sacramentally, she gives him, Pledges then with fair white bread the hero.

It was built in a romantic-neoclassical style as a strictly symmetrical building. The massive masonry was covered in yellow plaster. Laves planned a new district, the Ernst-August-Stadt, for the area between Georgstraße and the railway. Roads led from several directions and converged on the station forecourt, the Ernst-August-Platz.

From 1818 on, the palace was named Georgenpalais and the gardens name changed into Georgengarten. In 1826 the architect and engineer Georg Ludwig Friedrich Laves designed two smaller wings adjacent to the left and right side of the Wallmodenschloss. From 1828 until 1843 the formal garden was redesigned as an English style landscape garden.

In the 19th century the castle was occasionally used by the Hanoverian royal household as a summer residence. As a result, Georg Ludwig Friedrich Laves had several interior alterations made in 1839 and 1840. During World War I, it was used as a detention camp for officers (Offizerslager or Oflag) by the German Army.

CoCrCuFeNi is an fcc alloy that was found to be paramagnetic. But upon adding titanium, it forms a complex microstructure consisting of fcc solid solution, amorphous regions and nanoparticles of Laves phase, resulting in superparamagnetic behavior. High magnetic coercivity has been measured in a BiFeCoNiMn alloy. Superconductivity was observed in TaNbHfZrTi alloys, with transition temperatures between 5.0 and 7.3 K.

Former water features, canals and so on, were enlarged into a pond. Between 1835 and 1841 the then head gardener, Christian Schaumburg, was responsible for some redesign. During these years, three bridges designed by Laves were built: 1837 the Fahrbrücke, in 1840 the Augustenbrücke, and in the same year, the Friederikenbrücke. The latter is the only remaining bridge of the three.

Helium-nitrogen (He(N2)11) crystals have been grown at room temperature at pressures ca. 10 GPa in a diamond anvil cell. Solid argon- hydrogen clathrate (Ar(H2)2) has the same crystal structure as the MgZn2 Laves phase. It forms at pressures between 4.3 and 220 GPa, though Raman measurements suggest that the H2 molecules in Ar(H2)2 dissociate above 175 GPa.

Today it connects the Georgengarten and the Great Garden (Großer Garten) within the Herrenhausen Gardens. At the city end of the Herrenhäuser Allee, in 1857, a gate was built after plans made by Laves. The gate separated Königsworther Platz (Königsworther square) from the alley and the Georgengarten. In the 1960s, the gate was demolished, but in 2007, a replica with some remaining original parts was placed there.

British custom disregarded the Salic law, as a result of which Hanover and Britain no longer shared a single monarch. King Ernest Augustus, who had served as ruler of Hanover since 1837, was an enthusiastic backer of Arenhold's initiative and gifted to her association the "Weisshaarschen Hof" (court complex) in Calenberger Neustadt, across the river from what then counted as the Hanover city centre. The complex was rebuilt by the court architect, Georg Laves. The king paid.

His collection of materials from his fieldwork sat in storage until Mark Francillon (an anthropology student at the University of Chicago) heard about it and made contact with Laves in 1983. He arranged for the collection to be copied and deposited (as were the originals, sometime later) in the library at the Australian Institute of Aboriginal and Torres Strait Islander Studies. The collection of Aboriginal objects he acquired during his fieldwork in Australia is now held in the National Museum of Australia.

Moreover, the diamond crystal as a network in space has a strong isotropic property. Namely, for any two vertices x and y of the crystal net, and for any ordering of the edges adjacent to x and any ordering of the edges adjacent to y, there is a net-preserving congruence taking x to y and each x-edge to the similarly ordered y-edge. Another (hypothetical) crystal with this property is the Laves graph (also called the K4 crystal, (10,3)-a, or the diamond twin).

Only six eruptions outside of the caldera have been recorded, most recently in 1986. The village of Piton-Sainte-Rose was evacuated in 1977 before it was inundated by a lava flow which destroyed several buildings. The lava flow crossed the highway and surrounded the local church, entered the front door, then stopped without destroying the building. The front entrance was later cleared out, and the church was brought back into service under the name of Notre-Dame des Laves ("Our Lady of the Lavas").

The Grubenhagen Line of the House of Welf died out in 1596 and it fell to other Welf lines, who did not use the castle for 200 years. In 1815/16 Duke Adolf Frederick of Cambridge took ownership of the castle from the desmesne of Rotenkirchen. As viceroy of the Kingdom of Hanover the duke had the timber-framed manor house in Rotenkirchen converted by master builder Laves into an elegant hunting lodge. He also had the stables built onto the existing castle tower.

The first description of the grammar of their language, Garadjeri, was published by Gerhardt Laves in 1931. It belongs to the Marngu branch of the Pama-Nyungan language family. The native conceptualization of its varieties recognizes 4 dialect forms, the Najanaja (or Murrkut) dialect spoken by coastal Karajarri, Nangu spoken in the central hinterlands and Nawurtu further east inland. Garadjeri has had a notable influence on the Yawuru language, many of whose terms for ceremonials, and for naming the indigenous flora and fauna, have been borrowed from the Karajarri.

The service of washing off the dirt and brushing done by a Sansuke is called Nagashi. When announced by Bandai that there are customers, a Sansuke laves hot water into Oke and calls the customers in. In case there are many customers, the Sansuke must take care of the waiting list and wash the customers swiftly. The Sansuke offers service for both men and women; he may be required to work in crowds of naked women, whereby he must apply his mental training to prevent himself from having an erection.

The metastable dication, which is valence-isoelectronic with carbonyl fluoride and phosgene, was observed in 2010. Argon-36, in the form of argon hydride (argonium) ions, has been detected in interstellar medium associated with the Crab Nebula supernova; this was the first noble-gas molecule detected in outer space. Solid argon hydride (Ar(H2)2) has the same crystal structure as the MgZn2 Laves phase. It forms at pressures between 4.3 and 220 GPa, though Raman measurements suggest that the H2 molecules in Ar(H2)2 dissociate above 175 GPa.

In 1914 Goldschmidt applied for a professorship in Stockholm and was offered the position. To entice him to stay, the University of Kristiania persuaded the government to establish a mineralogical institute with a professorship for him. In 1929 Goldschmidt was appointed the chair of mineralogy in Göttingen, and he hired Reinhold Mannkopff and Fritz Laves as his assistants. However, after the rise of the Nazis to power, he became unhappy with the treatment of non-Aryans like himself (although the university treated him well) and he resigned in 1935 and returned to Oslo.

The edges of the resulting geometric graph are diagonals of a subset of the faces of the regular skew polyhedron with six square faces per vertex, so the Laves graph is embedded in this skew polyhedron. It is possible to interleave two copies of the structure, filling one-fourth of the points of the integer lattice, while preserving the fact that the adjacent vertices are exactly the pairs of points that are units apart, and all other pairs of points are farther apart. The two copies are mirror images of each other.

The Laves graph is a cubic graph (there are exactly three edges at each vertex) and a symmetric graph (every incident pair of a vertex and an edge can be transformed into every other such pair by a symmetry of the graph). The girth of this structure is 10 — the shortest cycles in the graph have 10 vertices — and 15 of these cycles pass through each vertex. The cells of the Voronoi diagram of this structure are heptadecahedra with 17 faces each. They are plesiohedra, polyhedra that tile space isohedrally.

After his fieldwork he returned to Chicago, married [1932] and followed his mentor, Edward Sapir, to Yale in New Haven, CT where he continued his graduate studies. Before completing his Ph.D. (which he never finished) he left Yale to be a teacher on the Navajo reservation at Shiprock, New Mexico. Several years later he returned to Chicago where he began a career with the International Harvester Company in Chicago. Laves never returned to linguistics or anthropology and only published two notes based on his work on Australian languages (listed below).

On the outside, the double canopy dome is a steep and conical element, covered with laves in the form of scales, which hinder the erosion that rainwater can produce. At the highest point it ends with a fluted ball, which has given rise to the popular name of Torre del Melón. Sometimes changes in the use of the chapter house led to changes in adaptability, as occurred in 1508, when the library donated by Dr. Gutiérrez Álvarez was installed in it, or as in 1544, when it was converted into the Main Chapel while the back wall of the Cathedral was demolished.

This resulted in the establishment of "Integrativen Stadtteilarbeit," an organisation which is externally moderated by the Hanoverian company KoriS. Since 2006, the organisation has been concerned with the revival of Lavesstraße as a High Street.

In 2004, a study by the Lower Saxony State Office for Consumer Protection and Food Safety (LAVES) on heavy metal pollution in red deer and roe deer, found high concentrations of lead and cadmium in the area of the silver smelting works in their livers and kidneys and partly also in their muscles. However, the residues of arsenic, antimony and mercury in muscles and storage organs were only small. The levels of cadmium in the organs exceeded the residue levels of the EU's Contaminants Regulation, in some cases, considerably. However, this regulation does not apply to the meat and edible tissues of wild game.

Central station in about 1850 (steel engraving) Ernest August Monument; virtual cutting of a donation of a full page of The Illustrated London News The first station on the current site, a temporary building that served the line to Lehrte, was erected in 1843. Instead of building a monumental terminus, a through station was built along with the line, making it the first through station in a major German city. The first central station (Central- Bahnhof) was built from 1845 to 1847. Its architect is not certain, but it is sure that the far-sighted city architect August Heinrich Andrae was involved in selecting its specific location and that the Hanoverian court architect Georg Ludwig Friedrich Laves and Ferdinand Schwarz contributed to it.

Ernest's interest in and support of the railroads led to Hanover becoming a major railway junction, much to the nation's benefit. However, when court architect Georg Ludwig Friedrich Laves in 1837 proposed the building of an opera house in Hanover, the King initially refused, calling the proposal "this utterly absurd idea of building a court theatre in the middle of this green field". The King finally gave his consent in 1844 and the opera house opened in 1852, a year after the King's death. Every week, the King travelled with his secretary to different parts of his kingdom, and anyone could lay a petition before him—although Ernest had petitions screened by the secretary so he would not have to deal with frivolous complaints.

Hemut Knocke studied architecture, with a special focus on the history of building, at the Leibniz University Hannover in his home city, Hannover, graduating in 1983. He has worked for the Cultural heritage inventarisation department and worked at the Hannover City Archive Office where the focus of his work was on the built and documentary legacies of the architects Georg Ludwig Friedrich Laves (1788-1864) and (1910-1999). He also involved himself in research projects at the university Institute for Arts and Buildings History ("Institut für Bau- und Kunstgeschichte"). Knocke is co- author, together with Hugo Thielen, of the Hannover Artistic and Cultural Lexicon ("Hannover Kunst- und Kultur-Lexikon "), of which an expanded and updated fourth edition appeared in 2007, and which has become a standard work on various of its themes.

The steel is first annealed at approximately for 15–30 minutes for thin sections and for 1 hour per 25 mm thickness for heavy sections, to ensure formation of a fully austenitized structure. This is followed by air cooling or quenching to room temperature to form a soft, heavily dislocated iron-nickel lath (untwinned) martensite. Subsequent aging (precipitation hardening) of the more common alloys for approximately 3 hours at a temperature of 480 to 500 °C produces a fine dispersion of Ni3(X,Y) intermetallic phases along dislocations left by martensitic transformation, where X and Y are solute elements added for such precipitation. Overaging leads to a reduction in stability of the primary, metastable, coherent precipitates, leading to their dissolution and replacement with semi-coherent Laves phases such as Fe2Ni/Fe2Mo.

The spread of this style of architecture in the region of Hanover can be traced back to the work of the Hanoverian Church consistorial master builder and architecture professor Conrad Wilhelm Hase (1818–1902) and his teachings at the Technical University of Hannover. There he taught from 1849 to 1894, among other subjects, Entwerfen öffentlicher und privater Gebäude ("Design of public and private buildings"), Höhere Baukunst (Advanced architecture), Formenlehre ("Structures"), and Ornamentik ("Ornamentation"). With traditional, conservative principles such as "adherence to the old" and "truth and clarity in art", Hase developed a contemporary style which favored stylistically purer, medieval forms, in a move away from Georg Laves' neo-classical, neo- Baroque architectural style acquired from France. His architectural style – dubbed occasionally by his supporters and critics as "Hasik" – was marked by the medieval brick Gothic design.

Every dual uniform tiling is in a 1:1 correspondence with the corresponding uniform tiling, by construction of the planigons above and superimposition. Such periodic tilings may be classified by the number of orbits of vertices, edges and tiles. If there are k orbits of planigons, a tiling is known as k-dual-uniform or k-isohedral; if there are t orbits of dual vertices, as t-isogonal; if there are e orbits of edges, as e-isotoxal. k-dual-uniform tilings with the same vertex figures can be further identified by their wallpaper group symmetry, which is identical to that of the corresponding k-uniform tiling. 1-dual-uniform tilings include 3 regular tilings, and 8 Laves tilings, with 2 or more types of regular degree vertices. There are 20 2-dual-uniform tilings, 61 3-dual-uniform tilings, 151 4-dual- uniform tilings, 332 5-dual-uniform tilings and 673 6--dualuniform tilings.
