Michael Hanack
Georg Michael Hanack (22 October 1931 – 6 November 2019) was a professor of chemistry at the University of Tübingen in Germany. Life and career Hanack was born in Luckenwalde on 22 October 1931. From 1949 to 1954 he studied chemistry, philosophy and economics at the universities of Freiburg, Bonn and Tübingen, and obtained his Diplomchemiker degree in 1954. In 1957, he completed his thesis under the supervision of Walter Hückel on "Solvolyse der Toluolsulfonate der stereoisomeren cis-alpha-Hydrindanole und Beiträge zur Messmethodik" (''Solvolysis of toluenesulfonates of stereoisomeric cis-alpha-hydrindanoles and contributions to the methodology of kinetic measurements''). After being an assistant to Hückel from 1957 to 1958, Hanack conducted his own research on topics such as organofluorine chemistry, organic chemistry and stereochemistry. After his habilitation in 1961, he was granted the title Privatdozent when he was only 31 years old, at that time one of the younges ...

Luckenwalde
Luckenwalde (; Upper and dsb, Łukowc) is the capital of the Teltow-Fläming district in the German state of Brandenburg. It is situated on the Nuthe river north of the Fläming Heath, at the eastern rim of the Nuthe-Nieplitz Nature Park, about south of Berlin. The town area includes the villages of Frankenfelde and Kolzenburg. Overview The former Slavic settlement of ''Lugkin'' was conquered by Margrave Conrad Wettin of Meissen in the course of the 1147 Wendish Crusade. ''Lukenwalde'' Castle was first mentioned in a 1216 deed as a burgward of the Bishopric of Brandenburg, it was acquired by Zinna Abbey in 1285. Together with Zinna it remained under the rule of the Archbishopric of Magdeburg and its successor, the Prussian Duchy of Magdeburg until it was attached to the Margraviate of Brandenburg in 1773. Originating in the 17th century, Luckenwalde's cloth and wool factories did not spring up till the reign of King Frederick II of Prussia and soon were among th ...

Stereochemistry
Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation. The study of stereochemistry focuses on the relationships between stereoisomers, which by definition have the same molecular formula and sequence of bonded atoms (constitution), but differ in structural formula (the three-dimensional orientations of their atoms in space). For this reason, it is also known as 3D chemistry—the prefix "stereo-" means "three-dimensionality". Stereochemistry spans the entire spectrum of organic, inorganic, biological, physical and especially supramolecular chemistry. Stereochemistry includes methods for determining and describing these relationships; the effect on the physical or biological properties these relationships impart upon the molecules in question, and the manner in which these relationships influence the reactivity of the molecules in question (dynamic stereochem ...

Doctoral Advisor
A doctoral advisor (also dissertation director, dissertation advisor; or doctoral supervisor) is a member of a university faculty whose role is to guide graduate students who are candidates for a doctorate, helping them select coursework, as well as shaping, refining and directing the students' choice of sub- discipline in which they will be examined or on which they will write a dissertation. Students generally choose advisors based on their areas of interest within their discipline, their desire to work closely with particular graduate faculty, and the willingness and availability of those faculty to work with them. In some countries, the student's advisor serves as the chair of the dissertation committee or the examination committee. In some cases, though, the person who serves those roles may be different from the faculty member who has most closely advised the student. For instance, in the Dutch academic system, only full professors (''hoogleraren'') and associate professors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phthalocyanines
Phthalocyanine () is a large, aromatic, macrocyclic, organic compound with the formula and is of theoretical or specialized interest in chemical dyes and photoelectricity. It is composed of four isoindole units linked by a ring of nitrogen atoms. = has a two-dimensional geometry and a ring system consisting of 18 π-electrons. The extensive delocalization of the π-electrons affords the molecule useful properties, lending itself to applications in dyes and pigments. Metal complexes derived from , the conjugate base of , are valuable in catalysis, organic solar cells, and photodynamic therapy. Properties Phthalocyanine and derived metal complexes (MPc) tend to aggregate and, thus, have low solubility in common solvents. Benzene at 40 °C dissolves less than a milligram of or CuPc per litre. and CuPc dissolve easily in sulfuric acid due to the protonation of the nitrogen atoms bridging the pyrrole rings. Many phthalocyanine compounds are, thermally, very stable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Professor Emeritus
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Proto ...
