Sam Francis
Samuel Lewis Francis (June 25, 1923, San Mateo, California – November 4, 1994, Santa Monica, California) was an American painter and printmaker. He was born in San Mateo, California, and studied botany, medicine and psychology at the University of California, Berkeley. He served in the United States Air Force during World War II before being injured in a plane crash. He was in the hospital for several years, and it was while he was there that he began to paint. Once he was out of the hospital he returned to Berkeley, this time to study art.
Francis was initially influenced by the work of abstract expressionists such as Mark Rothko, Arshile Gorky and Clyfford Still. He spent the 1950s in Paris, having his first exhibition there in 1952. While there he became associated with Tachisme. He later spent time in Japan, and some have seen an influence from Zen Buddhism in Francis’ work.
Francis spent some time in Paris making entirely monochromatic works, but his mature pieces are generally large oil paintings with splashed or splattered areas of bright contrasting colour. Areas of white canvas are often left to show through, and in later works, paint is sometimes confined to the edges of the canvas.
Francis returned to California during the 1960s and continued painting in Los Angeles. During the final three decades of his career his style of large scale bright Abstract Expressionism was also closely associated with Color Field painting. During the last year of his life, suffering from prostate cancer and unable to paint with his right hand after a fall, in a final burst of energy he used his left hand to complete a dazzling series of about 150 small paintings before he died. He was buried in Olema, in Marin County, California.
After the death of the artist, the Samuel L. Francis Foundation, Inc. (also known as the "Samuel L. Francis Art Museum, Inc." or the "Sam Francis Foundation") was founded. The Foundation not only serves as his official Estate, but also has a mission "to research, document, protect and perpetuate the creative legacy of [Francis]." The U.S. copyright representative for the Francis Foundation is the Artists Rights Society.
As of 2008, the Foundation is working to create a Catalogue Raisonné of Francis's work. In addition to collecting information on known Francis works, they also have a page dedicated to "missing works" for which they are seeking any information interested parties may have.
In 2010, artist and filmmaker Jeffrey Perkins released the documentary "The Painter Sam Francis". The documentary includes film of Francis at work, filmed between 1968 and the early '90s together with interviews with friends, family, and professional associates of Francis.
Sodium periodate
Sodium periodate is a chemical compound. Its chemical formula can be NaIO (sodium metaperiodate) or NaIO (sodium orthoiodate). It has sodium and periodate ions in it.
Sodium periodate is a colorless solid. It reacts with acids to make periodic acid. It breaks down when heated to make sodium iodate and oxygen gas. It is a strong oxidizing agent.
It can be made by oxidation of sodium iodide with sodium hypochlorite in a nitric acid solution.
Sodium periodate can oxidize cellulose. It is also used as a biodegradable chemical in the human body. It is also used in organic chemistry reactions.
7 Up
7 Up is a product of a lemon-lime flavored caffeinate-free soft drink. The rights to the brand are held by Dr Pepper Snapple Group in the United States, and PepsiCo (or its licensees) in the rest of the world, including Puerto Rico. The origin of the name is unclear. It has been reformulated several times since its launch in 1929. 7-Up Soft Drink contains no caffeine and now has no artificial ingredients or preservatives, and only half the sodium as before. It is distributed by the 7-Up/Dr. Pepper company. The company promotes the product as having a crisper, more refreshing lemon-lime taste than before.
7 up is type of goods from the Dr Pepper company, it started produce at 1987. At other country, 7 up is goods from Pepsi Co. It first produced in Missouri, St.Louis.
Periodic acid
Periodic acid (pronounced as per·io'·dic acid) is a chemical compound. It is also an acid. Its chemical formula is HIO or HIO. It has hydrogen and periodate ions in it.
Periodic acid is found as a colorless solution. It is a strong oxidizing agent, like perchloric acid. It breaks down when heated to iodine pentoxide and oxygen, as well as water. It does not form IO. It is found as HIO4 in dilute solution and H5IO6 in concentrated solution. When H5IO6 is heated, it turns into HIO4.
It is made by reacting a periodate with a strong acid.
It is used to look at the structure of certain organic compounds.
Periodate
Periodate is an ion. Its chemical formula is either IO (metaperiodate) or IO (orthoperiodate). They are the salts of periodic acid. The iodine is in its +7 oxidation state. Periodates are similar to perchlorates. They are strong oxidizing agents. Sodium periodate is the most common periodate.
Potassium periodate
Potassium periodate is a chemical compound. Its chemical formula is KIO. It has potassium and periodate ions in it.
Potassium periodate is a white solid. It is an oxidizing agent. It is similar to potassium perchlorate. It does not dissolve good in water. It makes potassium iodate and oxygen when heated.
It is made by reacting potassium iodide with a strong oxidizing agent.
It is used to find out how much potassium is in something because it is one of the few potassium compounds that do not dissolve easily in water.
Rey, Iran
Rey, Rayy, Ray, Rhages or Rages (; ; ) also known as Shahr-e-Rey (), is the oldest city in the state of Tehran, Iran. Rey today has been added into the Greater Tehran city. It is linked by the Tehran Metro to the rest of Tehran and has many industries and factories in use. A settlement began here c 6,000 BCE as part of the Central Plateau Culture. The settlement was used as a capital by the Medes called Rhaga. In classical Roman geography it was called Rhagae. Its name dates back to the pre-Median. Some historians point its building to very old storybook royal family, and some others believe that Rey was the seat of a house of Zoroastrian leader.
Iodine heptafluoride
Iodine heptafluoride is a chemical compound. Its chemical formula is IF. It contains iodine and fluoride ions. The iodine is in its +7 oxidation state.
It is a colorless gas with a moldy, stinky odor. Its melting point is at , and its boiling point is at . This means that it has a very narrow liquid range. It is a powerful oxidizing agent. It is very irritating to the skin. It is an interhalogen.
It is made by reacting iodine pentafluoride with fluorine gas.
Hypoiodous acid
Hypoiodous acid is a chemical compound. It is also an acid. Its chemical formula is HIO. It has hydrogen and hypoiodite ions in it.
Hypoiodous acid is very unstable. It easily disproportionates to iodine and iodic acid. It is a disinfectant and oxidizing agent.
It is made by reacting mercury(II) oxide with iodine.
It is too unstable to be used, although people think that this is what makes iodine a disinfectant.
Hypoiodite
Hypoiodite is an ion. Its chemical formula is IO. It is very unstable. It easily disproportionates to iodide and iodate. It is made by reacting iodine with a base. The iodine is in its +1 oxidation state. It is the salt of hypoiodous acid.
Iodine trifluoride
Iodine trifluoride is a chemical compound. Its chemical formula is IF. It has iodine and fluoride ions in it. The iodine is in its +3 oxidation state.
Iodine trifluoride is a yellow solid. It breaks down above -28°C. It is made by reacting very cold fluorine with iodine.
