Fred Basolo
Fred Basolo (11 February 1920 – 27 February 2007) was an American inorganic chemist. He received his Ph.D. at the University of Illinois at Urbana-Champaign in 1943, under Prof. John C. Bailar, Jr. Basolo spent his professional career at Northwestern University. He was a prolific contributor to the fields of coordination chemistry, organometallic, and bioinorganic chemistry, publishing over 400 papers. He supervised many Ph.D. students. With colleague Ralph Pearson, he co-authored the influential monograph "Mechanisms of Inorganic Reactions", which illuminated the importance of mechanisms involving coordination compounds. This work, which integrated concepts from ligand field theory and physical organic chemistry, signaled a shift from a highly descriptive nature of coordination chemistry to a more quantitative science. Biography Giovanni Basolo and Catherina Morena Basolo immigrated from the Piedmont area of Italy to Illinois. They had three children there; the youngest w ...

Coello, Illinois
North City is a village in Franklin County, Illinois, United States. As of the 2020 census, the population was 509. North City is also known as "Coello". The current mayor is Curtis Overton. History North City incorporated in 1915. Its name comes from two nearby coal mines which were nicknamed "New North" and "Old North." A post office, known as "Coello" after its first postmaster, Pete Coello, opened in 1918. Both "North City" and "Coello" are commonly used in the village.Franklin County, Illinois, 1818-1997' (Turner Publishing Company, 1996), pp. 12-13.

Ligand Field Theory
Ligand field theory (LFT) describes the bonding, orbital arrangement, and other characteristics of coordination complexes. It represents an application of molecular orbital theory to transition metal complexes. A transition metal ion has nine valence atomic orbitals - consisting of five ''n''d, one (''n''+1)s, and three (''n''+1)p orbitals. These orbitals are of appropriate energy to form bonding interaction with ligands. The LFT analysis is highly dependent on the geometry of the complex, but most explanations begin by describing octahedral complexes, where six ligands coordinate to the metal. Other complexes can be described by reference to crystal field theory.G. L. Miessler and D. A. Tarr "Inorganic Chemistry" 3rd Ed, Pearson/Prentice Hall publisher, . History Ligand field theory resulted from combining the principles laid out in molecular orbital theory and crystal field theory, which describes the loss of degeneracy of metal d orbitals in transition metal complexes.

Myoglobin
Myoglobin (symbol Mb or MB) is an iron- and oxygen-binding protein found in the cardiac and skeletal muscle tissue of vertebrates in general and in almost all mammals. Myoglobin is distantly related to hemoglobin. Compared to hemoglobin, myoglobin has a higher affinity for oxygen and does not have cooperative binding with oxygen like hemoglobin does. In humans, myoglobin is only found in the bloodstream after muscle injury. (Google books link is the 2008 edition) High concentrations of myoglobin in muscle cells allow organisms to hold their breath for a longer period of time. Diving mammals such as whales and seals have muscles with particularly high abundance of myoglobin. Myoglobin is found in Type I muscle, Type II A, and Type II B; although many texts consider myoglobin not to be found in smooth muscle, this has proved erroneous: there is also myoglobin in smooth muscle cells. Myoglobin was the first protein to have its three-dimensional structure revealed by X-ray crystal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indenyl Effect
In organometallic chemistry, a transition metal indenyl complex is a coordination compound that contains one or more indenyl ligands. The indenyl ligand is formally the anion derived from deprotonation of indene. The η5-indenyl ligand is related to the η5cyclopentadienyl anion (Cp), thus indenyl analogues of many cyclopentadienyl complexes are known. Indenyl ligands lack the 5-fold symmetry of Cp, so they exhibit more complicated geometries. Furthermore, some indenyl complexes also exist with only η3-bonding mode. The η5- and η3-bonding modes sometimes interconvert. Preparation and structure Indene is deprotonated by butyl lithium and related reagents to give the equivalent of the indenyl anion: :C9H8 + BuLi → LiC9H7 + BuH The resulting lithium indenide can be used to prepare indenyl complexes by salt metathesis reactions of metal halides. When the metal halide is easily reduced, the trimethylstannylindenyl can be used as a source of indenyl anion: :Me3SnC9H7 + ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
