• chiral
  • Commonly, the magnetic catalysis is specifically associated with spontaneous breaking of flavor or chiral symmetry in quantum field theory, which is enhanced or triggered by the presence of an external magnetic field. (wikipedia.org)
  • biomass
  • Target applications include fuels, specialty and bulk chemicals, environmental catalysis, biomass conversion to fuels and chemicals, conversion of greenhouse gases, and generation of solar hydrogen, as well as efficient routes to energy utilization. (nsf.gov)
  • Renewable energy-related catalysis with applications in electrocatalysis, photocatalysis, and catalytic conversion of biomass-derived chemicals. (nsf.gov)
  • mechanism
  • The underlying mechanism behind magnetic catalysis is the dimensional reduction of low-energy charged spin-1/2 particles. (wikipedia.org)
  • The mechanism of magnetic catalysis in a relativistic-like planar systems such as graphene is very natural. (wikipedia.org)
  • The mechanism of enzyme catalysis is similar in principle to other types of chemical catalysis. (wikipedia.org)
  • There are six possible mechanisms of "over the barrier" catalysis as well as a "through the barrier" mechanism: Enzyme-substrate interactions align the reactive chemical groups and hold them close together in an optimal geometry, which increases the rate of the reaction. (wikipedia.org)
  • transformations
  • Study of this branch of catalysis led to the development of new methods to accomplish known and new chemical transformations. (wikipedia.org)
  • A major portion of the group's basic research is aimed at research into the Fundamentals of Catalysis and Chemical Transformations sponsored by the DOE's Office of Science, Basic Energy Sciences, Chemical Sciences, Geosciences, and Biosciences Division. (ornl.gov)
  • mechanisms
  • After binding takes place, one or more mechanisms of catalysis lowers the energy of the reaction's transition state, by providing an alternative chemical pathway for the reaction. (wikipedia.org)
  • reactant
  • The system must be thoroughly studied to find the optimal conditions for both the catalysis and reactant to produce the desired product. (wikipedia.org)
  • Research
  • Professor Hagen's teaching and research at the faculty of Chemical and Process Engineering focused on chemical reaction engineering and technical catalysis. (wiley-vch.de)
  • This topic touches a myriad of aspects in the broad spectrum of catalysis research. (rsc.org)
  • donors
  • In these cases, catalysis with hydrogen-bond donors is an attractive strategy since the anionic tetrahedral intermediates are better hydrogen-bond acceptors than the starting compound. (wikipedia.org)
  • chemical
  • Catalysis (/kəˈtælɪsɪs/) is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst (/ˈkætəlɪst/), which is not consumed in the catalyzed reaction and can continue to act repeatedly. (wikipedia.org)
  • Photoredox catalysis is a branch of catalysis that harnesses the energy of light to accelerate a chemical reaction via single-electron transfer events. (wikipedia.org)
  • In particular, photoredox catalysis employs small quantities of a light-sensitive compound that, when excited by light, can mediate the transfer of electrons between chemical compounds that otherwise would react more slowly or not at all. (wikipedia.org)
  • Play media Enzyme catalysis is the increase in the rate of a chemical reaction by the active site of a protein. (wikipedia.org)
  • That is, the chemical catalysis is defined as the reduction of Ea‡ (when the system is already in the ES‡) relative to Ea‡ in the uncatalyzed reaction in water (without the enzyme). (wikipedia.org)
  • This technique has been deployed in tandem alkane-dehydrogenation-olefin-metathesis catalysis Concurrent Tandem Catalysis Julia-Christina Wasilke, Stephen J. Obrey, R. Tom Baker, and Guillermo C. Bazan Chemical Reviews 2005 105 (3), 1001-1020 doi:10.1021/cr020018n Beach, B. L. (wikipedia.org)
  • Catalysis aimed at closing the carbon cycle (especially conversion of CO2, methane, and natural gas to fuels and chemical intermediates). (nsf.gov)
  • molecule
  • In all cases, the close association of the catalyst molecule to substrate also makes hydrogen-bond catalysis a powerful method of inducing enantioselectivity. (wikipedia.org)
  • aldehydes
  • This type of catalysis allows for the functionalization of simple alkenes into aldehydes and gives a remarkably useful handle to generate other functional groups. (wikipedia.org)
  • nanoparticles
  • One of the topics that was set out as needing in depth discussion was the topic concerning catalysis using nanoparticles. (rsc.org)
  • These sites are often considered to be the active centres for catalysis but there are reports of colloidal nanoparticles that are unsupported being active. (rsc.org)
