"Paternò's reaction", known since the early twentieth century, was renamed to the "Paternò–Büchi reaction The Paternò–Büchi reaction, named after Emanuele Paternò and George Büchi, who established its basic utility and form, is a photochemical reaction, specifically a 2+2 photocycloaddition, which forms four-membered oxetane rings from an excit ..." based on enhancements made to it by Büchi's research group.

University Of Palermo Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Senate Of The Kingdom Of Italy
The Senate of the Kingdom of Italy () was the upper house of the bicameral parliament of the Kingdom of Italy, officially created on 4 March 1848, acting as an evolution of the original Subalpine Senate. It was replaced on 1 January 1948 by the present-day Senate of the Republic. All of its members were appointed by the King. History The Senate of the Kingdom of Italy rose to national prominence in 1860, following the Unification of Italy, as the direct successor of the Subalpine Senate of the Kingdom of Sardinia, with the addition of members drawn from the territories obtained during the Second Italian War of Independence and the Expedition of the Thousand. The Senate was initially based at the Palazzo Madama in Turin until 1864, when it was moved to the Palazzo Vecchio in Florence. Finally, in 1871, it was moved to the Palazzo Madama in Rome. During the fascist regime, there was no "fascistisation" (''fascistizzazione'') of the Senate equivalent to that carried out in ...

List Of Mayors Of Palermo
The mayor of Palermo is an elected politician who, along with the Palermo's city council, is accountable for the strategic government of Palermo in Sicily, Italy. The current mayor is Roberto Lagalla, who took office on 20 June 2022. Overview According to the Italian Constitution, the mayor of Palermo is a member of the Palermo city council.

The mayor is entitled to appoint and release the members of his government. Since 1993 the mayor has been elected directly by Palermo's electorate: in all mayoral elections in Italy in cities with a population higher than 15,000 the voters express a direct choice for the mayor or an indirect choice voting for the party of the candidate's coalition. If no candidate receives at least 50% of votes, the top two candidates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Photochemistry
Photochemistry is the branch of chemistry concerned with the chemical effects of light. Generally, this term is used to describe a chemical reaction caused by absorption of ultraviolet (wavelength from 100 to 400 nm), visible light (400–750 nm) or infrared radiation (750–2500 nm). In nature, photochemistry is of immense importance as it is the basis of photosynthesis, vision, and the formation of vitamin D with sunlight. Photochemical reactions proceed differently than temperature-driven reactions. Photochemical paths access high energy intermediates that cannot be generated thermally, thereby overcoming large activation barriers in a short period of time, and allowing reactions otherwise inaccessible by thermal processes. Photochemistry can also be destructive, as illustrated by the photodegradation of plastics. Concept Grotthuss–Draper law and Stark-Einstein law Photoexcitation is the first step in a photochemical process where the reactant is elevated ...

University Of Palermo
The University of Palermo ( it, Università degli Studi di Palermo) is a university located in Palermo, Italy, and founded in 1806. It is organized in 12 Faculties. History The University of Palermo was officially founded in 1806, although its earliest roots date back to 1498 when medicine and law were taught there. A little later in history, from the second half of the 16th century from their seat at the Collegio Massimo al Cassero, the Jesuit Fathers granted degrees in Theology and Philosophy - subjects in which they had been masters for over 200 years. In 1767 they were expelled from the kingdom by King Ferdinand I, until 37 years later, when they returned to take their seat - which in the meantime had been turned into the Regia Accademia. At this time, the same King Ferdinand decided to grant a good seat to the Accademia, moving its location to the Convent of the Teatini Fathers next to the Church of St. Giuseppe. After the unification of Italy in 1860, the University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Of Paternò
A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems.Schoenauer, Norbert (2000). ''6,000 Years of Housing'' (rev. ed.) (New York: W.W. Norton & Company). Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses may have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
