Chemical Reactions Accelerated by Freezing.

Freezing of Spinodal Decomposition by Irreversible Chemical Growth Reactions

We present a description of the freezing of spinodal decomposition in systems, which contain simultaneous irreversible chemical reactions, in the hydrodynamic limit approximation. From own results we conclude, that the chemical reaction leads to an onset of spinodal decomposition also in the case of an initial system which is completely miscible and can lead to an extreme retardation of the dyn...

Chemical modulators of heat shock protein 70 (Hsp70) by sequential, microwave-accelerated reactions on solid phase.

Molecular chaperones, such as Hsp70 and Hsp90, are responsible for a variety of protective, anti-apoptotic functions. While inhibitors of Hsp90, such as geldanamycin and its derivative 17-AAG, are well known and important anti-cancer leads, Hsp70 has received less attention. Interesting lead candidates for Hsp70 share a dihydropyrimidine core; however, the preferred display of pendant functiona...

Real time monitoring of accelerated chemical reactions by ultrasonication-assisted spray ionization mass spectrometry.

Ultrasonication has been used to accelerate chemical reactions. It would be ideal if ultrasonication-assisted chemical reactions could be monitored by suitable detection tools such as mass spectrometry in real time. It would be helpful to clarify reaction intermediates/products and to have a better understanding of reaction mechanism. In this work, we developed a system for ultrasonication-assi...

Speeding chemical reactions by focusing.

We present numerical results for a chemical reaction of colloidal particles which are transported by a laminar fluid and are focused by periodic obstacles in such a way that the two components are well mixed and consequently the chemical reaction is speeded up. The roles of the various system parameters (diffusion coefficients, reaction rate, and obstacles sizes) are studied. We show that focus...
