Sarajevo

Sarajevo (Bosnia/Croatian/Serbian cyrillic Сарајево) (Serbo-Croatian pronunciation: [sǎrajeʋo]) is the capital and largest city of Bosnia and Herzegovina, with an estimated population of 369,534. The Sarajevo metropolitan area, including Sarajevo, East Sarajevo and surrounding municipalities, is home to 688,354 inhabitants. Moreover, it is also the capital of the Federation of Bosnia and Herzegovina entity,and the center of the Sarajevo Canton. Nestled within the greater Sarajevo valley of Bosnia, it is surrounded by the Dinaric Alps and situated along the Miljacka River in the heart of Southeastern Europe and the Balkans.

Sarajevo is the leading political, social and cultural center of Bosnia and Herzegovina, a prominent center of culture in the Balkans, with its region-wide influence in entertainment, media, fashion, and the arts.

The city is famous for its traditional cultural and religious diversity, with adherents of Islam, Orthodoxy, Judaism and Catholicism coexisting there for centuries. Due to its long and rich history of religious and cultural variety, Sarajevo is sometimes called the "Jerusalem of Europe" or "Jerusalem of the Balkans". It was, until late in the 20th century, the only major European city to have a mosque, Catholic church, Orthodox church and synagogue within the same neighborhood. A regional center in education, the city is also home to the Balkans' first institution of tertiary education in the form of an Islamic polytechnic called the Saraybosna Osmanlı Medrese, today part of the University of Sarajevo.

Sarajevo (1940 French film)

Sarajevo (French:De Mayerling à Sarajevo) is a 1940 French historical film directed by Max Ophüls and starring Edwige Feuillère, John Lodge and Aimé Clariond. Beginning in the aftermath of the Mayerling Incident the film portrays the love affair and marriage between Archduke Franz Ferdinand of Austria and Sophie, Duchess of Hohenberg, leading up to their eventual assassination in 1914 in events that triggered the First World War. The film was not a commercial or critical success. Following the German occupation of France the film was banned, and Ophüls fled into exile for the second time.

Dioxygen difluoride

Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula O
2F
2. It exists as an orange solid that melts into a red liquid at −163 °C (110 K). It is an extremely strong oxidant and decomposes into oxygen and fluorine even at −160 °C (113 K) at a rate of 4% per day: its lifetime at room temperature is thus extremely short. Dioxygen difluoride reacts with nearly every chemical it encounters – even ordinary ice – leading to its onomatopoeic nickname "FOOF" (a play on its chemical structure).

The material has no practical applications, but has been of theoretical interest. One laboratory's use of it was the synthesis of plutonium hexafluoride at unprecedentedly low temperatures, which was significant because previous methods for its preparation needed temperatures so high that the plutonium hexafluoride created would rapidly decompose.

Preparation

Dioxygen difluoride can be obtained by subjecting a 1:1 mixture of gaseous fluorine and oxygen at low pressure (7–17 mmHg is optimal) to an electric discharge of 25–30 mA at 2.1–2.4 kV. A similar method was used for the first synthesis by Otto Ruff in 1933. Another synthesis involves mixing O
2 and F
2 in a stainless steel vessel cooled to −196 °C (77.1 K), followed by exposing the elements to 6987480652946100000♠3 MeV bremsstrahlung for several hours. A third method requires heating a mix of fluorine and oxygen to 700 °C (1,292 °F), and then rapidly cooling it using liquid oxygen. All of these methods involve synthesis according to the equation:
