Lourdes Salamanca-Riba
Lourdes (, also , ; oc, Lorda ) is a market town situated in the Pyrenees. It is part of the Hautes-Pyrénées department in the Occitanie region in southwestern France. Prior to the mid-19th century, the town was best known for the Château fort de Lourdes, a fortified castle that rises up from a rocky escarpment at its center. In 1858 Lourdes rose to prominence in France and abroad due to the Marian apparitions claimed to have been seen by the peasant girl Bernadette Soubirous, who was later canonized. Shortly thereafter the city with the Sanctuary of Our Lady of Lourdes became one of the world's most important sites of pilgrimage and religious tourism. History Antiquity The current municipal area of Lourdes was inhabited in prehistoric times. In Roman times it had to be, since the first century BC, an oppidum hill where today stands the fortress, as is testified by the numerous finds that came to light in the second half of the nineteenth century (remains of walls, frag ...

United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet. The current Secretary of Energy is Jennifer Granholm, who has served ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryogenic Electron Microscopy
Cryogenic electron microscopy (cryo-EM) is a cryomicroscopy technique applied on samples cooled to cryogenic temperatures. For biological specimens, the structure is preserved by embedding in an environment of vitreous ice. An aqueous sample solution is applied to a grid-mesh and plunge-frozen in liquid ethane or a mixture of liquid ethane and propane. While development of the technique began in the 1970s, recent advances in detector technology and software algorithms have allowed for the determination of biomolecular structures at near-atomic resolution. This has attracted wide attention to the approach as an alternative to X-ray crystallography or NMR spectroscopy for macromolecular structure determination without the need for crystallization. In 2017, the Nobel Prize in Chemistry was awarded to Jacques Dubochet, Joachim Frank, and Richard Henderson "for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution."

Ulrich Dahmen
Ulrich (), is a German given name, derived from Old High German ''Uodalrich'', ''Odalric''. It is composed of the elements '' uodal-'' meaning "(noble) heritage" and ''-rich'' meaning "rich, powerful". Attested from the 8th century as the name of Alamannic nobility, the name is popularly given from the high medieval period in reference to Saint Ulrich of Augsburg (canonized 993). There is also a surname Ulrich. It is most prevalent in Germany and has the highest density in SwitzerlandThis last name was found in the United States around the year 1840Most Americans with the last name were concentrated in Pennsylvania, which was home to many Pennsylvania Dutch, German immigrant communities. Nowadays in the United States, the name is distributed largely in the Pennsylvania-Ohio regio History Documents record the Old High German name ''Oadalrich'' or ''Uodalrich'' from the later 8th century in Alamannia. The related name ''Adalric'' (Anglo-Saxon cognate '' Æthelric'') is attested fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multiferroic
Multiferroics are defined as materials that exhibit more than one of the primary ferroic properties in the same phase: * ferromagnetism – a magnetisation that is switchable by an applied magnetic field * ferroelectricity – an electric polarisation that is switchable by an applied electric field * ferroelasticity – a deformation that is switchable by an applied stress While ferroelectric ferroelastics and ferromagnetic ferroelastics are formally multiferroics, these days the term is usually used to describe the ''magnetoelectric multiferroics'' that are simultaneously ferromagnetic and ferroelectric. Sometimes the definition is expanded to include nonprimary order parameters, such as antiferromagnetism or ferrimagnetism. In addition, other types of primary order, such as ferroic arrangements of magnetoelectric multipoles of which ferrotoroidicity is an example, have also been recently proposed. Besides scientific interest in their physical properties, multiferroics have pote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
