Michael J. S. Dewar
Michael James Steuart Dewar (24 September 1918 – 10 October 1997) was an American theoretical chemist. Education and early life Dewar was the son of Scottish parents, Annie Balfour (Keith) and Francis Dewar. He received the degrees of Bachelor of Arts, Master of Arts, and DPhil from Balliol College, Oxford. Career and research Dewar was appointed to the Chair in Chemistry at Queen Mary College of the University of London in 1951. He moved to the University of Chicago in 1959 and then to the first Robert A. Welch research chair at the University of Texas at Austin in 1963. After a long and productive period there, he moved to the University of Florida in 1989. He retired in 1994 as Professor Emeritus at the University of Florida. He died in 1997. Dewar's reputation for providing original solutions to vexing puzzles first developed when he was still a postdoctoral fellow at the University of Oxford. In 1945, he deduced the correct structure for stipitatic acid, a mould prod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ahmednagar
Ahmednagar (), is a city located in the Ahmednagar district in the state of Maharashtra, India, about 120 km northeast of Pune and 114 km from Aurangabad. Ahmednagar takes its name from Ahmad Nizam Shah I, who founded the town in 1494 on the site of a battlefield where he won a battle against superior Bahamani forces. It was close to the site of the village of Bhingar. With the breakup of the Bahmani Sultanate, Ahmad established a new sultanate in Ahmednagar, also known as Nizam Shahi dynasty. Ahmednagar has several dozen buildings and sites from the Nizam Shahi period. Ahmednagar Fort, once considered almost impregnable, was used by the British to house Jawaharlal Nehru (the first prime minister of India) and other Indian Nationalists before Indian independence. A few rooms there have been converted to a museum. During his confinement by the British at Ahmednagar Fort in 1944, Nehru wrote the famous book ''The Discovery of India''. Ahmednagar is home to the Indian A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aromatic
In chemistry, aromaticity is a chemical property of cyclic ( ring-shaped), ''typically'' planar (flat) molecular structures with pi bonds in resonance (those containing delocalized electrons) that gives increased stability compared to saturated compounds having single bonds, and other geometric or connective non-cyclic arrangements with the same set of atoms. Aromatic rings are very stable and do not break apart easily. Organic compounds that are not aromatic are classified as aliphatic compounds—they might be cyclic, but only aromatic rings have enhanced stability. The term ''aromaticity'' with this meaning is historically related to the concept of having an aroma, but is a distinct property from that meaning. Since the most common aromatic compounds are derivatives of benzene (an aromatic hydrocarbon common in petroleum and its distillates), the word ''aromatic'' occasionally refers informally to benzene derivatives, and so it was first defined. Nevertheless, many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Texas At Austin
The University of Texas at Austin (UT Austin, UT, or Texas) is a public research university in Austin, Texas. It was founded in 1883 and is the oldest institution in the University of Texas System. With 40,916 undergraduate students, 11,075 graduate students and 3,133 teaching faculty as of Fall 2021, it is also the largest institution in the system. It is ranked among the top universities in the world by major college and university rankings, and admission to its programs is considered highly selective. UT Austin is considered one of the United States's Public Ivies. The university is a major center for academic research, with research expenditures totaling $679.8 million for fiscal year 2018. It joined the Association of American Universities in 1929. The university houses seven museums and seventeen libraries, including the LBJ Presidential Library and the Blanton Museum of Art, and operates various auxiliary research facilities, such as the J.

Balliol College, Oxford
Balliol College () is one of the constituent colleges of the University of Oxford in England. One of Oxford's oldest colleges, it was founded around 1263 by John I de Balliol, a landowner from Barnard Castle in County Durham, who provided the foundation and endowment for the college. When de Balliol died in 1268, his widow, Dervorguilla, a woman whose wealth far exceeded that of her husband, continued his work in setting up the college, providing a further endowment and writing the statutes. She is considered a co-founder of the college. The college's alumni include four former Prime Ministers of the United Kingdom (H. H. Asquith, Harold Macmillan, Edward Heath, and Boris Johnson), Harald V of Norway, Empress Masako of Japan, five Nobel laureates, several Lords of Appeal in Ordinary, and numerous literary and philosophical figures, including Shoghi Effendi, Adam Smith, Gerard Manley Hopkins, and Aldous Huxley.

Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common Academic degree, degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor (title), Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theoretical Chemistry
Theoretical chemistry is the branch of chemistry which develops theoretical generalizations that are part of the theoretical arsenal of modern chemistry: for example, the concepts of chemical bonding, chemical reaction, valence, the surface of potential energy, molecular orbitals, orbital interactions, and molecule activation. Overview Theoretical chemistry unites principles and concepts common to all branches of chemistry. Within the framework of theoretical chemistry, there is a systematization of chemical laws, principles and rules, their refinement and detailing, the construction of a hierarchy. The central place in theoretical chemistry is occupied by the doctrine of the interconnection of the structure and properties of molecular systems. It uses mathematical and physical methods to explain the structures and dynamics of chemical systems and to correlate, understand, and predict their thermodynamic and kinetic properties. In the most general sense, it is explanation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
