Charles Soret
Charles Soret (born 23 September 1854, Geneva, Switzerland; died 4 April 1904) was a Swiss physicist and chemist. He is known for his work on thermodiffusion (the so-called ''Soret effect''). Life Charles Soret was the son of Jacques-Louis Soret, professor of physical medicine at University of Geneva, and Clémentine Odier. In 1872, Charles graduated from an art college in Geneva and, two years later, he added a degree in mathematics. In addition, he also attended lectures in physics and other sciences. He continued studies in mathematics at the Sorbonne, where he received his MA in 1876. He believed that a good physicist is first of all a good mathematician; therefore, only afterwards he focused on physics in which he obtained a master's degree two years later. Soon, he was offered a place in the Department of crystallography and mineralogy at the University of Geneva. There, in 1879, he became a lecturer and a full professor in 1881. In 1879, he published his first discussi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thermodiffusion
Thermophoresis (also thermomigration, thermodiffusion, the Soret effect, or the Ludwig–Soret effect) is a phenomenon observed in mixtures of mobile particles where the different particle types exhibit different responses to the force of a temperature gradient. This phenomenon tends to move light molecules to hot regions and heavy molecules to cold regions. The term ''thermophoresis'' most often applies to aerosol mixtures whose mean free path \lambda is comparable to its characteristic length scale L, but may also commonly refer to the phenomenon in all phases of matter. The term ''Soret effect'' normally applies to liquid mixtures, which behave according to different, less well-understood mechanisms than gaseous mixtures. Thermophoresis may not apply to thermomigration in solids, especially multi-phase alloys. Thermophoretic force The phenomenon is observed at the scale of one millimeter or less. An example that may be observed by the naked eye with good lighting is when the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques-Louis Soret
Jacques-Louis Soret (30 June 1827 – 13 May 1890) was a Swiss chemist and spectroscopist. He studied both spectroscopy and electrolysis. He held the chairs of chemistry (1873-1887) and medical physics (1887-1890) at the University of Geneva. Soret determined the chemical composition and density of ozone and the conditions for its production. He described it correctly as being composed of three oxygen atoms bound together. Soret also developed optical instruments. He climbed Mont Blanc, where he was the first scientist to make actinometric measurements of solar radiation. These observations were published in the ''Philosophical Magazine'' in 1867. In 1878, he and Marc Delafontaine were the first to spectroscopically observe the element later named holmium, which they identified simply as an "earth X" derived from "erbia". Independently, Per Teodor Cleve separated it chemically from thulium and erbium in 1879. All three researchers are given credit for the element's dis ...

Carl Ludwig
Carl Friedrich Wilhelm Ludwig (; 29 December 1816 – 23 April 1895) was a German physician and physiologist. His work as both a researcher and teacher had a major influence on the understanding, methods and apparatus used in almost all branches of physiology. In 1842, Ludwig became a professor of physiology and in 1846 of comparative anatomy. From professorships in Zurich and Vienna he went in 1865 to the University of Leipzig and developed there the Physiological Institute, designated today after him: Carl Ludwig Institute of Physiology.Current website of the Carl-Ludwig-Institute of Physiology http://cliphys.uniklinikum-leipzig.de/ Ludwig researched several topics such as the physiology of blood pressure, urinary excretion, and anesthesia. He received the Copley Medal in 1884 for his research. In 1869, he was elected a foreign member of the Royal Swedish Academy of Sciences. He is credited for inventing the stromuhr. Since 1932, the Carl Ludwig Honorary Medal is awarded b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Refractometry
Refractometry is the analytical method of measuring substances' refractive index (one of their fundamental physical properties) in order to, for example, assess their composition or purity. A refractometer is the instrument used to measure refractive index ("RI"). Although refractometers are best known for measuring liquids, they are also used to measure gases and solids; such as glass and gemstones. The RI of a substance is strongly influenced by temperature and the wavelength of light used to measure it, therefore, care must be taken to control or compensate for temperature differences and wavelength. RI measurements are usually reported at a reference temperature of 20 degrees Celsius, which is equal to 68 degrees Fahrenheit, and considered to be room temperature. A reference wavelength of 589.3 nm (the sodium D line) is most often used. Though RI is a dimensionless quantity, it is typically reported as nD20 (or n), where the "n" represents refractive index, the "D" denote ...
