Ignaz Kreidl
Ignaz Kreidl (December 11, 1869, in Gratzen, Austria-Hungary – May 21, 1947, in New York City, NY, USA) was a chemist and industrialist living in Vienna, Austria. He held numerous patents related to the production and use of rare earths and the production of glass, enamels, and synthetic resins. In addition to founding the chemical company Vereinigte Chemischen Fabriken (VCF), he became a major shareholder in , a leading glass manufacturer. In the 1930s Kreidl became a target of the National Socialists. During the Anschluss his wife Eva died, and his possessions were confiscated. Kreidl and his three sons were able to leave Austria and emigrate to the United States. After the end of World War II they were able to reclaim some of his business assets. Early life Ignaz Kreidl was born on December 11, 1869, in Gratzen, Austria-Hungary (now Nové Hrady (České Budějovice District), South Bohemian Region, Czech Republic).

Carl Auer Von Welsbach
Carl Auer von Welsbach (1 September 1858 – 4 August 1929), who received the Austrian noble title of Freiherr Auer von Welsbach in 1901, was an Austrian scientist and inventor, who separated didymium into the elements neodymium and praseodymium in 1885. He was also one of three scientists to independently discover the element lutetium (which he named ''cassiopeium''), separating it from ytterbium in 1907, setting off the longest priority dispute in the history of chemistry. He had a talent not only for making scientific advances, but also for turning them into commercially successful products. His work on rare-earth elements led to the development of the ferrocerium "flints" used in modern lighters, the gas mantle that brought light to the streets of Europe in the late 19th century, and the metal-filament light bulb. He took the phrase ''plus lucis'', meaning "more light", as his motto. Early life Carl Auer was born in Vienna on 1 September 1858 to Alois Auer and h ...

Elizabeth Rona
Elizabeth Rona (20 March 1890 – 27 July 1981) was a Hungarian nuclear chemist, known for her work with radioactive isotopes. After developing an enhanced method of preparing polonium samples, she was recognized internationally as the leading expert in isotope separation and polonium preparation. Between 1914 and 1918, during her postdoctoral study with George de Hevesy, she developed a theory that the velocity of diffusion depended on the mass of the nuclides. As only a few atomic elements had been identified, her confirmation of the existence of "Uranium-Y" (now known as thorium-231) was a major contribution to nuclear chemistry. She was awarded the Haitinger Prize by the Austrian Academy of Sciences in 1933. After immigrating to the United States in 1941, she was granted a Carnegie Fellowship to continue her research and provided technical information on her polonium extraction methods to the Manhattan Project. Later in her career, she became a nuclear chemistry profess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diabetics
Diabetes, also known as diabetes mellitus, is a group of metabolic disorders characterized by a high blood sugar level (hyperglycemia) over a prolonged period of time. Symptoms often include frequent urination, increased thirst and increased appetite. If left untreated, diabetes can cause many health complications. Acute complications can include diabetic ketoacidosis, hyperosmolar hyperglycemic state, or death. Serious long-term complications include cardiovascular disease, stroke, chronic kidney disease, foot ulcers, damage to the nerves, damage to the eyes, and cognitive impairment. Diabetes is due to either the pancreas not producing enough insulin, or the cells of the body not responding properly to the insulin produced. Insulin is a hormone which is responsible for helping glucose from food get into cells to be used for energy. There are three main types of diabetes mellitus: * Type 1 diabetes results from failure of the pancreas to produce enough insulin due to loss o ...

Saccharin
Saccharin (''aka'' saccharine, Sodium sacchari) is an artificial sweetener with effectively no nutritional value. It is about 550 times as sweet as sucrose but has a bitter or metallic aftertaste, especially at high concentrations. Saccharin is used to sweeten products such as drinks, candies, cookies, and especially for masking bitter taste of some medicines. Etymology Saccharin derives its name from the word "saccharine", meaning "sugary". The word saccharine is used figuratively, often in a derogative sense, to describe something "unpleasantly over-polite" or "overly sweet". Both words are derived from the Greek word (''sakkharon'') meaning "gravel". Similarly, saccharose is an obsolete name for sucrose (table sugar). Properties Saccharin is heat-stable. It does not react chemically with other food ingredients; as such, it stores well. Blends of saccharin with other sweeteners are often used to compensate for each sweetener's weaknesses and faults.

Austro-Hungarian Empire
Austria-Hungary, often referred to as the Austro-Hungarian Empire,, the Dual Monarchy, or Austria, was a constitutional monarchy and great power in Central Europe between 1867 and 1918. It was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War and was dissolved shortly after its defeat in the First World War. Austria-Hungary was ruled by the House of Habsburg and constituted the last phase in the constitutional evolution of the Habsburg monarchy. It was a multinational state and one of Europe's major powers at the time. Austria-Hungary was geographically the second-largest country in Europe after the Russian Empire, at and the third-most populous (after Russia and the German Empire). The Empire built up the fourth-largest machine building industry in the world, after the United States, Germany and the United Kingdom. Austria-Hungary also became the world's third-largest manufacturer and exporter of electric home appliances ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Praseodymium
Praseodymium is a chemical element with the symbol Pr and the atomic number 59. It is the third member of the lanthanide series and is considered to be one of the rare-earth metals. It is a soft, silvery, malleable and ductile metal, valued for its magnetic, electrical, chemical, and optical properties. It is too reactive to be found in native form, and pure praseodymium metal slowly develops a green oxide coating when exposed to air. Praseodymium always occurs naturally together with the other rare-earth metals. It is the sixth-most abundant rare-earth element and fourth-most abundant lanthanide, making up 9.1 parts per million of the Earth's crust, an abundance similar to that of boron. In 1841, Swedish chemist Carl Gustav Mosander extracted a rare-earth oxide residue he called didymium from a residue he called "lanthana", in turn separated from cerium salts. In 1885, the Austrian chemist Baron Carl Auer von Welsbach separated didymium into two elements that gave salts of diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neodymium
Neodymium is a chemical element with the symbol Nd and atomic number 60. It is the fourth member of the lanthanide series and is considered to be one of the rare-earth metals. It is a hard, slightly malleable, silvery metal that quickly tarnishes in air and moisture. When oxidized, neodymium reacts quickly producing pink, purple/blue and yellow compounds in the +2, +3 and +4 oxidation states. It is generally regarded as having one of the most complex spectra of the elements. Neodymium was discovered in 1885 by the Austrian chemist Carl Auer von Welsbach, who also discovered praseodymium. It is present in significant quantities in the minerals monazite and bastnäsite. Neodymium is not found naturally in metallic form or unmixed with other lanthanides, and it is usually refined for general use. Neodymium is fairly common—about as common as cobalt, nickel, or copper—and is widely distributed in the Earth's crust. Most of the world's commercial neodymium is mined in China, as ...
