Physical Chemistry
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular science, as the majority of the principles on which it was founded relate to the bulk rather than the molecular or atomic structure alone (for example, chemical equilibrium and colloids). Some of the relationships that physical chemistry strives to resolve include the effects of: # Intermolecular forces that act upon the physical properties of materials ( plasticity, tensile strength, surface tension in liquids). # Reaction kinetics on the rate of a reaction. # The identity of ions and the electrical conductivity of materials. # Surface science and electrochemistry of cell membrane ...

Platinocyanide
Platinocyanide, also known as tetracyanoplatinate (IUPAC), cyanoplatinate, or platinocyanate, is a polyatomic ion with the molecular formula t(CN)4sup>2−. The name also applies to compounds containing this ion, which are salts of the hypothetical platinocyanic acid (sometimes platinocyanhydric acid). Barium platinocyanide, Ba t(CN)4is a phosphor and a scintillator. It fluoresces in the presence of x-rays and gamma rays. It was important in the discovery of X-rays, and in the development of the fluoroscope. One platinocyanide salt, Krogmann's salt (dipotassium tetracyanoplatinate bromide trihydrate), has unusually high electric conductance. Cyano complexes Phosphors and scintillators Cyanides Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms.

Indiana University Alumni
Indiana () is a U.S. state in the Midwestern United States. It is the 38th-largest by area and the 17th-most populous of the 50 States. Its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th state on December 11, 1816. It is bordered by Lake Michigan to the northwest, Michigan to the north, Ohio to the east, the Ohio River and Kentucky to the south and southeast, and the Wabash River and Illinois to the west. Various indigenous peoples inhabited what would become Indiana for thousands of years, some of whom the U.S. government expelled between 1800 and 1836. Indiana received its name because the state was largely possessed by native tribes even after it was granted statehood. Since then, settlement patterns in Indiana have reflected regional cultural segmentation present in the Eastern United States; the state's northernmost tier was settled primarily by people from New England and New York, Central Indiana by migrants from the ...

Lutheran Church–Missouri Synod
The Lutheran Church—Missouri Synod (LCMS), also known as the Missouri Synod, is a traditional, confessional Lutheran denomination in the United States. With 1.8 million members, it is the second-largest Lutheran body in the United States. The LCMS was organized in 1847 at a meeting in Chicago, Illinois, as the German Evangelical Lutheran Synod of Missouri, Ohio, and Other States (german: Die Deutsche Evangelisch-Lutherische Synode von Missouri, Ohio und andern Staaten), a name which partially reflected the geographic locations of the founding congregations. The LCMS has congregations in all 50 U.S. states and two Canadian provinces, but over half of its members are located in the Midwest. It is a member of the International Lutheran Council and is in altar and pulpit fellowship with most of that group's members. The LCMS is headquartered in Kirkwood, Missouri, and is divided into 35 districts—33 of which are geographic and two (the English and the SELC) non-geographic. The cur ...

Albright College
Albright College is a private liberal arts college in Reading, Pennsylvania. It was founded in 1856. History Albright College traces its founding to 1856 when Union Seminary opened. Present-day Albright was formed by the mergers of several institutions: Albright Collegiate Institute, Central Pennsylvania College, and Schuylkill College. Albright Collegiate Institute opened in 1895 and was renamed Albright College three years later. Union Seminary, meanwhile, became Central Pennsylvania College in 1887 and merged with Albright College in 1902. Schuylkill Seminary, the third institution, was founded in 1881, became Schuylkill College in 1923, and merged into Albright in 1928. Albright's campus relocated from Myerstown, to Schuylkill College's campus, which is the present location of Albright, at the base of Mount Penn in Reading. The college is named for Pennsylvania-German evangelical preacher Jacob Albright, who founded the Evangelical Association (later known as the Evangel ...

Luminescence
Luminescence is spontaneous emission of light by a substance not resulting from heat; or "cold light". It is thus a form of cold-body radiation. It can be caused by chemical reactions, electrical energy, subatomic motions or stress on a crystal. This distinguishes luminescence from incandescence, which is light emitted by a substance as a result of heating. Historically, radioactivity was thought of as a form of "radio-luminescence", although it is today considered to be separate since it involves more than electromagnetic radiation. The dials, hands, scales, and signs of aviation and navigational instruments and markings are often coated with luminescent materials in a process known as "luminising". Types The following are types of luminescence: * Chemiluminescence, the emission of light as a result of a chemical reaction **Bioluminescence, a result of biochemical reactions in a living organism **Electrochemiluminescence, a result of an electrochemical reaction **Lyolumine ...

Phosphorescence
Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs. Instead, a phosphorescent material absorbs some of the radiation energy and reemits it for a much longer time after the radiation source is removed. In a general sense, there is no distinct boundary between the emission times of fluorescence and phosphorescence (i.e.: if a substance glows under a black light it is generally considered fluorescent, and if it glows in the dark it is often simply called phosphorescent). In a modern, scientific sense, the phenomena can usually be classified by the three different mechanisms that produce the light, and the typical timescales during which those mechanisms emit light. Whereas fluorescent materials stop emit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorescence
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detection, vacu ...

History On August 18, 1827, Joseph Holman bought land near the confluence of the Mississinewa River, Mississinewa and Wabash River, Wabash Rivers from Jean Baptiste Richardville, Jean Baptiste "Pechewa" (Wildcat) Drouet de Richardville, the chief of the Miami people, Miami Indians. The sale was approved on March 3, 1828 by President John Quincy Adams. On March 12, 1829, Holm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
