Synchysite-(Ce) is a carbonate mineral and an end member of the synchysite group. The general chemical formula is Ca(Ce,La)(CO

2F. [2]
Synchysite-(Ce) was discovered in 1900 by Gustaf Flink. [3] The name is derived from the Greek "σύγχΰσις", meaning "confounding", a reference to the possibility to confuse the mineral with Parisite-(Ce).
Synchysite-(Ce) is found in rare-earth element bearing pegmatites. [4] It can also occur as a hydrothermal mineral in granite, alkalic syenite and carbonatite. [1]
Strontianite (SrCO3) is an important raw material for the extraction of strontium. It is a rare carbonate mineral and one of only a few strontium minerals. It is a member of the aragonite group.
Gustaf V was King of Sweden from 1907 until his death in 1950. He was the eldest son of King Oscar II of Sweden and Sophia of Nassau, a half-sister of Adolphe, Grand Duke of Luxembourg. Reigning from the death of his father, Oscar II, in 1907 to his own death 42 years later, he holds the record of being the oldest monarch of Sweden and the third-longest rule, after Magnus IV and Carl XVI Gustaf. He was also the last Swedish monarch to exercise his royal prerogatives, which largely died with him, although they were formally abolished only with the remaking of the Swedish constitution in 1974. He was the first Swedish king since the High Middle Ages not to have a coronation and so never wore the king's crown, a practice that has continued ever since.
Theodor Svedberg was a Swedish chemist and Nobel laureate for his research on colloids and proteins using the ultracentrifuge. Svedberg was active at Uppsala University from the mid 1900s to late 1940s. While at Uppsala, Svedberg started as a docent before becoming the university's physical chemistry head in 1912. After leaving Uppsala in 1949, Svedberg was in charge of the Gustaf Werner Institute until 1967. Apart from his 1926 Nobel Prize, Svedberg was named a Foreign Member of the Royal Society in 1944 and became part of the National Academy of Sciences in 1945.

FFV-Carl Gustaf was a Swedish armaments firm, bought up and merged on several occasions.
Cerium(IV) oxide, also known as ceric oxide, ceric dioxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare-earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2. It is an important commercial product and an intermediate in the purification of the element from the ores. The distinctive property of this material is its reversible conversion to a non-stoichiometric oxide.
Carbonate minerals are those minerals containing the carbonate ion, CO32−.
Prince Gustaf of Sweden and Norway, Duke of Uppland, also known officially as Gustav, was the second son of Oscar I of Sweden and Josephine of Leuchtenberg, and the younger brother of Prince Charles.
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element". Yttrium is almost always found in combination with lanthanide elements in rare-earth minerals, and is never found in nature as a free element. 89Y is the only stable isotope, and the only isotope found in the Earth's crust.
Cerium is a chemical element with the symbol Ce and atomic number 58. Cerium is a soft, ductile, and silvery-white metal that tarnishes when exposed to air, and it is soft enough to be cut with a steel kitchen knife. Cerium is the second element in the lanthanide series, and while it often shows the +3 oxidation state characteristic of the series, it also has a stable +4 state that does not oxidize water. It is also considered one of the rare-earth elements. Cerium has no biological role in humans and is not very toxic.
Caryopilite (synonymous with ectropite and ektropite) is a brown-colored mineral with formula (Mn2+,Mg)3Si2O5(OH)4. The mineral was discovered in 1889 from a mine in Sweden. It was named for the Greek words for walnut and felt in reference to its appearance.
Synchysite is a group of carbonate minerals. The three isostructural chemical end members are synchysite-(Ce), synchysite-(Nd) and synchysite-(Y). Huanghoite-(Ce) belongs to the group, but has a different symmetry and calcium is replaced by barium.
Gustaf Flink, born 18 January 1848 in Ås Parish, Skaraborg County, died 11 January 1931, was a Swedish mineralogist.

Apache Flink is an open-source, unified stream-processing and batch-processing framework developed by the Apache Software Foundation. The core of Apache Flink is a distributed streaming data-flow engine written in Java and Scala. Flink executes arbitrary dataflow programs in a data-parallel and pipelined manner. Flink's pipelined runtime system enables the execution of bulk/batch and stream processing programs. Furthermore, Flink's runtime supports the execution of iterative algorithms natively.
Steve Flink is an American sports journalist and historian. Flink, who has been a columnist and editor with such magazines as World Tennis Magazine, Tennis Week and Tennis Channel and published two monographs on the history of tennis, in 2017 was elected to the International Tennis Hall of Fame in the Contributor category.
The 2020 Monterrey Open was a women's tennis tournament played on outdoor hard courts. It was the 12th edition of the Monterrey Open and an International tournament on the 2020 WTA Tour. It took place at the Club Sonoma in Monterrey, Mexico, from 2 to 8 March 2020.
Britholite-(Ce) is a rare radioactive mineral with the chemical formula (Ce,Ca)5(SiO4)3OH. It comes in a variety of different colors. Its type locality is Naujakasik (Naajakasik), Tunulliarfik Fjord, Ilímaussaq complex, Narsaq, Kujalleq, Greenland.
