Jesse Francis McClendon
Jesse Francis McClendon (December 21, 1880 – November 22, 1976) was an American chemist, zoologist, and physiologist known for the first pH measurement of human stomach ''in situ''. McClendon made substantial contributions in a variety of fields, including invertebrate zoology, nutrition, life processes of cell membranes, the importance of pH control, the role of iodine in human health, and specifically its relation to prevention of goiters. During the early 1930s, McClendon tested the healthfulness of hamburgers by putting a University of Minnesota medical student on a diet of only hamburgers and water for thirteen weeks. Biography McClendon was born in Lanett, Alabama, on December 21, 1880. He completed his B.S. in 1903 and M.S. in 1904, both from the University of Texas. In 1903, he worked at the University of Texas under Dr. William Morton Wheeler. He then received a Ph.D. in zoology from the University of Pennsylvania in 1906. His PhD dissertation was entitled, "O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iodine
Iodine is a chemical element with the Symbol (chemistry), symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at , and boils to a violet gas at . The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek 'violet-coloured'. Iodine occurs in many oxidation states, including iodide (I−), iodate (), and the various periodate anions. It is the least abundant of the stable halogens, being the sixty-first most abundant element. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. The dominant producers of iodine today are Chile and Japan. Due to its high atomic number and ease of attachment to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platinum
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish , a diminutive of "silver". Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust, with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for ~80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity. Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. ...

Rubber Cement
Rubber cement (cow gum in British English) is an adhesive made from elastic polymers (typically latex) mixed in a solvent such as acetone, hexane, heptane or toluene to keep it fluid enough to be used. This makes it part of the class of drying adhesives: as the solvents quickly evaporate, the rubber solidifies, forming a strong yet flexible bond. Composition Rubber cement is simply a mixture of solid rubber in a volatile solvent that will dissolve it. When the cement is applied, the solvent evaporates, leaving the rubber as the adhesive. Almost any rubber (pre- vulcanized or not) can be used. The rubbers used might be natural rubber, gum mastic or gum arabic. Early solvents used included chloroform and benzene. A small percentage of alcohol is often added to the mix. In the United States, current formulations include n-heptane. In the United Kingdom, a product called Marabu-Fixogum uses acetone, while a product called Copydex uses ammonia. Many special compositions includ ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create br ...

William Morton Wheeler
William Morton Wheeler (March 19, 1865 – April 19, 1937) was an American entomologist, myrmecologist and Harvard professor. Biography Early life and education William Morton Wheeler was born on March 19, 1865, to parents Julius Morton Wheeler and Caroline Georgiana Wheeler ( Anderson) in Milwaukee, Wisconsin. At a young age, Wheeler had an interest in natural history, first being when he observed a moth ensnared in a spiders web; such observation interested Wheeler that he became importunate for more nature lore. Wheeler attended public school, but, due to "persistently bad behavior", he was transferred to a local German academy which was known for its extreme discipline. After he completed his courses in the German academy, he attended a German normal school. In both institutions, Wheeler was trained in a variety of subjects: he was given training in languages, philosophy and science. By this time, he could read fluently in French, German, Greek, Italian, Latin and Spanish. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
