Catalysis, the modification of the rate of a chemical reaction, usually an acceleration, by addition of a substance not consumed during the reaction. Each catalyst molecule may induce the transformation of many molecules of reactants. Learn about the his
In the development of novel electrochemical and biological sensors, clay modified electrodes (CLMEs) have received much interest. The fabrication procedure includes an overview of the type of clay particles (cationic or anionic), the electron transferring mechanism at the sensing surface, and the vari...
However, our trials to generate the enone starting materials using the organobismuth catalyst were unsuccessful, which is why for these products the full cascade could not be established. It is also interesting to note that YqjM (I69Y/C26G), compared to the wt parent, exhibited higher ...
an emergent bioprocess platform technology is the potential for operation with high solids retention time [98]. This invites the use of biofilms as an immobilized catalyst. For whole cells, physical entrapment is ultimately enabled by the adhesion of the biofilms EPS to suitable support (e.g., ...

A catalyst changes the transition state to lower the activation energy. A biological catalyst is called enzyme. active compound (pharm .) Generic medicinal products contain the same active compounds as the original products. active ingredient (pharm. ) Acronym: AI A drug is normally not ...
(single-step or multi-step reactions), used for applications of a particular catalyst, and various ways to carry out specific functional group transformations [59]. Another reaction database is REAXYS [60], based on Elsevier’s industry-leading chemistry databases that include data for more than...
Catalysed oxidative C-C bond formation reactions are important in the synthesis of natural products, but poorly tolerated by polyphenolic flavones. Here the authors report the reactivity of molecular oxygen in alkaline water without added catalyst for the synthesis of a collection of flavone dimers and...
Understanding how surface structure affects catalyst selectivity is limited by the ability to synthesize atomically precise active-site ensembles. Now, by using intermetallic Pd–Zn, a series of well-defined multinuclear Pd–metal–Pd catalytic sites have been generated and studied, providing insights in...
