Recent studies dealing with the electronic, chemical, and catalytic properties of well-defined bimetallic surfaces (prepared by vapor-depositing one metal onto a crystal face of a second metal) are discussed. The results show that a metal atom supported on a dissimilar metal can be electronically perturbed and that this perturbation can dramatically alter the chemical and catalytic properties o...

The optimization method is vital in chemical synthesis and has been applied many fields nowadays. Response surface methodology (RSM) an example of that useful examining the effects multiple independent variables. RSM was studies to optimize transesterification biodiesel production from palm oil presence a catalyst. This paper aims provide overview recent catalyzed trends, as well benefits drawb...

Catalysis in pharma manufacturing processes is typically homogeneous, expensive and with hard catalyst recovery/regeneration. Herein an enzyme-inspired dry-powder molecularly imprinted polymeric (MIP) system was designed for fast, selective oxidation of a cholesterol derivative easy regeneration. The strategy involved the synthesis template-monomer (T:M) complex followed by crosslinked polymeri...

Isomerization of linear alkanes has had considerable importance for the refining industry because the isomers formed in this reaction have high octane number. Most works reported in the literature studied the use of bifunctional catalysts, i.e., ones that have acid sites and metallic sites. In this study, bifunctional monometallic (Ni or Pt) and bimetallic catalysts (Pt-Ni), using HUSY zeolite ...

We present a general method for the computation of molecular population distributions in a system of first-order chemical reactions. The method is based on the observation that the molecules in first-order reactions do not interact with each other. Therefore, the population distributions are a convolution of densities for one molecule. With this method one can study reactions involving any numb...

Stoicheiometric amounts of [14C]disulfiram react rapidly with sheep liver cytoplasmic aldehyde dehydrogenase to give loss of catalytic activity and incorporation of the expected amount of radioactivity. In a subsequent slower reaction the label is lost from the enzyme without re-emergence of enzymic activity. The results imply that in vivo disulfiram may act as an oxidation-reduction catalyst f...
