aThe chemical reaction model requires the complete set of reaction parameters, which may be difficult to obtain especially if effects such as particle size change the kinetics of the reactions. Changes in the dominant reaction also may occur as temperature increases, further increasing the model ...
TSTU, as a new type of contraction, has given its unique structure to its excellent reaction performance. TSTU can generate high -response active ester intermediates by reaction to carboxylic acid reactions. The intermediate can quickly react with amine compounds to achieve high -efficiency amine bon...
According to the current rigid-surface model of catalysis, the tightly packed atoms of transition metal catalysts provide a 2D surface that chemical reactants adhere to and participate in reactions. When enough pressure and heat or electricity is applied, the bonds between atoms in the chemical re...
I was very lucky. Prof van Tamelen gave us all a lot of freedom--he didn’t lay down explicit directions about what to do in the lab. This helped me develop independence and confidence and maturity. When I was at the bench, most of my reactions didn't work---but I never regarded...
Research in this vein may one day allow chemists to synthesize materials—in particular natural compounds and other bioactive molecules with all-carbon-atom centers—that are currently difficult to create. It may even lead to entirely new types of chemical reactions that are not currently known or...
forward: the particular enzyme that catalyzes this Diels-Alder reaction could help improve one of the most commonly used chemical reactions, and they now have a clear picture of how the enzyme directs the reaction in nature and how it might be harnessed to create new compounds in the future....
The light-sensitive emulsion used to create holograms makes a record of the interference between the light waves in the reference and object beams. When two wave peaks meet, they amplify each other. This is constructive interference. When a peak meets a trough, they cancel one another out. Th...
coli to sense food, move around, eat and reproduce. So, in any living cell, DNA helps to create enyzmes, and enzymes create the chemical reactions that are "life." Bacteria reproduce asexually. This means that, when a bacteria cell splits, both halves of the split are identical -- ...
