Manfred Baerns
Manfred Baerns (23 July 1934 – 2 February 2021) was a German chemist. Career After a 2-years postdoctoral fellowship at the Argonne National Laboratory (Argonne, Illinois), a further 5 years in academia and a 5-year career in industry, was a full professor for chemical technology and reaction engineering at Ruhr-University Bochum (Germany) from 1974–1995. He then acted as scientific director of the "Institute of Applied Chemistry Berlin-Adlershof" until 2003. He was lately a guest scientist as Professor Emeritus at the "Fritz-Haber-Institute" of the Max-Planck-Society at Berlin. Baerns was a member of numerous scientific committees and a referee for research proposal at a national level. From 1991 to 1997 he was member of the board DECHEMA (a scientific association of chemical technology, chemical engineering and biotechnology), and a permanent member of the German Chemical Society, the German Bunsen Society for Physical Chemistry, German Society for Coal, Oil and Gas, and ...

Argonne National Laboratory
Argonne National Laboratory is a science and engineering research national laboratory operated by UChicago Argonne LLC for the United States Department of Energy. The facility is located in Lemont, Illinois, outside of Chicago, and is the largest national laboratory by size and scope in the Midwest. Argonne had its beginnings in the Metallurgical Laboratory of the University of Chicago, formed in part to carry out Enrico Fermi's work on nuclear reactors for the Manhattan Project during World War II. After the war, it was designated as the first national laboratory in the United States on July 1, 1946. In the post-war era the lab focused primarily on non-weapon related nuclear physics, designing and building the first power-producing nuclear reactors, helping design the reactors used by the United States' nuclear navy, and a wide variety of similar projects. In 1994, the lab's nuclear mission ended, and today it maintains a broad portfolio in basic science research, energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruhr University
The Ruhr University Bochum (, ) is a public research university located in the southern hills of the central Ruhr area, Bochum, Germany. It was founded in 1962 as the first new public university in Germany after World War II. Instruction began in 1965. The Ruhr-University Bochum is one of the largest universities in Germany and part of the Deutsche Forschungsgemeinschaft, the most important German research funding organization. The RUB was very successful in the Excellence Initiative of the German Federal and State Governments (2007), a competition between Germany's most prestigious universities. It was one of the few institutions left competing for the title of an "elite university", but did not succeed in the last round of the competition. There are currently nine universities in Germany that hold this title. The University of Bochum was one of the first universities in Germany to introduce international bachelor's and master's degrees, which replaced the traditional German Di ...

Professor
Professor (commonly abbreviated as Prof.) is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital letter nearly always refers to a full profes ...

Chemical Engineering
Chemical engineering is an engineering field which deals with the study of operation and design of chemical plants as well as methods of improving production. Chemical engineers develop economical commercial processes to convert raw materials into useful products. Chemical engineering uses principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, design, transport and transform energy and materials. The work of chemical engineers can range from the utilization of nanotechnology and nanomaterials in the laboratory to large-scale industrial processes that convert chemicals, raw materials, living cells, microorganisms, and energy into useful forms and products. Chemical engineers are involved in many aspects of plant design and operation, including safety and hazard assessments, process design and analysis, modeling, control engineering, chemical reaction engineering, nuclear engineering, biological engineering, construction specificati ...

Chemical Society
The Chemical Society was a scientific society formed in 1841 (then named the Chemical Society of London) by 77 scientists as a result of increased interest in scientific matters. Chemist Robert Warington was the driving force behind its creation. History One of the aims of the Chemical Society was to hold meetings for "the communication and discussion of discoveries and observations, an account of which shall be published by the Society". In 1847, its importance was recognised by a Royal Charter, which added to its role in the advancement of science, the development of chemical applications in industry. Its members included eminent chemists from overseas including August Wilhelm von Hofmann, who became its president in 1861. Membership was open to all those interested in chemistry, but fellowship was for long restricted to men. In 1904, Edith Humphrey, thought to be the first British woman to gain a doctorate in chemistry (at the University of Zurich), was one of nineteen women ch ...

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 cel ...

4th World
The Fourth World is an extension of the three-world model, used variably to refer to # Sub-populations socially excluded from global society, such as uncontacted peoples; # Hunter-gatherer, nomadic, pastoral, and some subsistence farming peoples living beyond the modern industrial norm. # Sub-populations existing in a First World country, but with the living standards of those of a Third World. The term is not commonly used. "Fourth World" has also been used to refer to other parts of the world in relation to the three-world model. Etymology ''Fourth World'' follows the First World, Second World, and Third World classification of nation-state status; however, unlike the former categories, ''Fourth World'' is not spatially bounded, and is usually used to refer to size and shape which does not map onto citizenship in a specific nation-state. It can denote nations without a sovereign state, emphasizing the perceived non-recognition and exclusion of ethnically- and religiously-de ...

University Of Technology
An institute of technology (also referred to as: technological university, technical university, university of technology, technological educational institute, technical college, polytechnic university or just polytechnic) is an institution of tertiary education (such as a university or college) that specializes in engineering, technology, applied science, and natural sciences. Institutes of technology versus polytechnics The institutes of technology and polytechnics have been in existence since at least the 18th century, but became popular after World War II with the expansion of engineering and applied science education, associated with the new needs created by industrialization. The world's first institution of technology, the Berg-Schola (today its legal successor is the University of Miskolc), was founded by the Court Chamber of Vienna in Selmecbánya, Kingdom of Hungary (now Banská Štiavnica, Slovakia), in 1735 in order to train specialists of precious metal and copper ...

Chemical Reaction
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei (no change to the elements present), and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. The substance (or substances) initially involved in a chemical reaction are called reactants or reagents. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. Reactions often consist of a sequence of individual sub-steps, the so-called elementary reactions, and the information on the precise co ...

Heterogeneous Catalysis
In chemistry, heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reactants or products. The process contrasts with homogeneous catalysis where the reactants, products and catalyst exist in the same phase. Phase distinguishes between not only solid, liquid, and gas components, but also immiscible mixtures (e.g. oil and water), or anywhere an interface is present. Heterogeneous catalysis typically involves solid phase catalysts and gas phase reactants. In this case, there is a cycle of molecular adsorption, reaction, and desorption occurring at the catalyst surface. Thermodynamics, mass transfer, and heat transfer influence the rate (kinetics) of reaction. Heterogeneous catalysis is very important because it enables faster, large-scale production and the selective product formation. Approximately 35% of the world's GDP is influenced by catalysis. The production of 90% of chemicals (by volume) is assisted by solid catalysts. The chemical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
