  Catalysis and Biocatalysis Technologies
Advancements in catalysis are a key spark in maintaining the impact of the chemical industry as a leading economic engine associated with contributions to a positive balance of trade.
With this growth in leverage through catalysis, it is no wonder that catalysis-based chemical synthesis now accounts for an estimated 60 percent of today's chemicals production and 90 percent of current processes.
Funding for catalysis from both the National Science Foundation and the Department of Energy have largely been concerned with support of basic/fundamental (i.e., discovery science) research and research targeted at the agency's mission at universities or within the national laboratories.

Catalysis is of vital importance: In biological systems, enzymes are essential catalysts for various biosynthetic pathways; in the chemical and petroleum industries, key processes are based on catalysis; in environmental chemistry, catalysts are essential to breaking down pollutants such as automobile and industrial exhausts.
Catalysis (a word suggested in 1835 by J.J. Berzelius [1779- 1848]) is a process whereby the rate of a particular chemical reaction is hastened, sometimes enormously so, by the presence of small quantities of a substance which does not itself seem to take part in the reaction.
The catalysis activity of the gel is thus expected to be switched on and off as the substrate is reversibly bound and released during the cycle of gel swelling and shrinking.

 Catalysis Summary
One of the examples of catalysis familiar to Berzelius was the conversion of starch to sugar in the presence of strong acids.
In chemistry and biology, catalysis is the acceleration (increase in rate) of a chemical reaction by means of a substance, called a catalyst, that is itself not consumed by the overall reaction.
Catalysis is important in many aspects of environmental science, from the catalytic converter in automobiles to the causes of the ozone hole.

 Asymmetric Catalysis - Interview with Dr. Masakatsu Shibasaki
Catalysis based on the bifunctional concept is now widely studied not only by us, but also many research groups all over the world.
Despite spectacular recent achievements in asymmetric catalysis, there remain confounding problems to be tackled in future research.
Sequential asymmetric catalysis, in which one asymmetric catalyst promotes more than one mechanistically distinct asymmetric reaction in one pot, is also desirable.

 Quantum Ontology: Minds, Brains & Catalysis
If we formulate the process of catalysis in autopoietic terms, then the catalyst would correspond to the closed autopoietic system and the reagents, products and the process of catalysis itself would correspond to an environmental perturbation.
By identifying the living process with the 'transition state' of a process of catalysis, the scale invariant catalytic model firmly roots the process of life in the environment.
By locating autopoiesis within the greater context of catalysis as the essential principle at work, we are better placed to understand the necessary relationship between autopoiesis, robustness, and the structure in the environment.

 Ostwald on catalysis   (Site not responding. Last check: )
"Catalysis is a condition of movement of the atoms in a molecule of a labile body which follows the entrance of the energy emitted from one body into another and leads to the formation of more stable bodies with loss of energy."
If the abstractor were to formulate for himself the problem of characterizing the phenomenon of catalysis in a general way, he would consider the following expression as probably most suitable: Catalysis is the acceleration of a chemical reaction, which proceeds slowly, by the presence of a foreign substance.
Catalytic processes are empirically found to be of the type in which this last property is observed; the existence of catalytic processes is to me therefore a positive proof that chemical processes cannot have a kinetic nature.
