DECHEMA
DECHEMA is an abbreviation for "Deutsche Gesellschaft für chemisches Apparatewesen" (German Society for Chemical Apparatus), though it has since been expanded to "''Deutsche Gesellschaft für Chemische Technik und Biotechnologie''" (German Society for Chemical Engineering and Biotechnology). Founded in 1926, this is a non-profit organisation based in Frankfurt. It has over 5000 chemists, biotechnologists, and engineers as personal members, as well as other organisations and company members. DECHEMA awards prizes, such as the DECHEMA medal "for outstanding achievements in the field of chemical apparatus technology." The main purpose of Dechema is to support developments in chemical technology, biotechnology, and environmental protection. It is seen as an interface between science, economy, industry, and the public. To this purpose the trade faiACHEMAis organised and held every three years in Frankfurt am Main, Germany, as the biggest event for chemical technology and biotechnology. ...

Frankfurt
Frankfurt, officially Frankfurt am Main (; Hessian: , " Frank ford on the Main"), is the most populous city in the German state of Hesse. Its 791,000 inhabitants as of 2022 make it the fifth-most populous city in Germany. Located on its namesake Main River, it forms a continuous conurbation with the neighboring city of Offenbach am Main and its urban area has a population of over 2.3 million. The city is the heart of the larger Rhine-Main metropolitan region, which has a population of more than 5.6 million and is Germany's second-largest metropolitan region after the Rhine-Ruhr region. Frankfurt's central business district, the Bankenviertel, lies about northwest of the geographic center of the EU at Gadheim, Lower Franconia. Like France and Franconia, the city is named after the Franks. Frankfurt is the largest city in the Rhine Franconian dialect area. Frankfurt was a city state, the Free City of Frankfurt, for nearly five centuries, and was one of the mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dortmund Data Bank
The Dortmund Data Bank (short DDB) is a factual data bank for thermodynamic and thermophysical data. Its main usage is the data supply for process simulation where experimental data are the basis for the design, analysis, synthesis, and optimization of chemical processes. The DDB is used for fitting parameters for thermodynamic models like NRTL or UNIQUAC and for many different equations describing pure component properties, e.g., the Antoine equation for vapor pressures. The DDB is also used for the development and revision of predictive methods like UNIFAC and PSRK. Contents Mixture properties * Phase equilibria data ( vapor–liquid, liquid–liquid, solid–liquid), data on azeotropy and zeotropy * Mixing enthalpies * Gas solubilities * Activity coefficients at infinite dilution * Heat capacities and excess heat capacities * Volumes, densities, and excess volumes (volume effect of mixing) * Salt solubilities * Octanol-water partition coefficients * Critical ...

European Federation Of Chemical Engineering
The European Federation of Chemical Engineering (EFCE), also known as Fédération Européenne du Génie Chimique and Europäische Föderation für Chemie-Ingenieur-Wesen, is an association of professional societies in Europe concerned with chemical engineering. It was formed in Paris on 20 June 1953 with 18 societies in 8 countries.''Trans IChemE, Vol 81, Part A,'' January 2003, pp 179-183 "European Federation of Chemical Engineering" India was the first non-European member in 1956 and Czechoslovakia the first Eastern European one in 1966. As of November 2016, it has 38 member societies in 29 countries joining 162000 individual chemical engineers. (Some countries have more than one member society). The EFCE passport programme allows members of one society some of the benefits of membership in other societies when travelling abroad, particularly for conferences. It has a set of 20 Working Parties and 5 Sections comprising about 1000 industrial and academic experts on different s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elektrolytdatenbank Regensburg
Elektrolytdatenbank Regensburg (abridged ELDAR) is a compilation of thermodynamic data, bibliography and properties of electrolytes and their solutions. History The gathering of data has begun since 1981. It is a member of DECHEMA and associate of Dortmund Data Bank. Content *Densities, dielectric constants *Thermal expansion and compressibility data *Electrical conductivity data *Solubility data *Activity and excess molar quantity In chemical thermodynamics, excess properties are properties of mixtures which quantify the non- ideal behavior of real mixtures. They are defined as the difference between the value of the property in a real mixture and the value that would exis ... data External linksofficial site {{Database-stub Chemical databases ...

Chemistry Societies
Chemistry is the scientific study of the properties and behavior of matter. It is a natural science that covers the elements that make up matter to the compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both basic and applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology), and how to collect DNA evidence a ...
