We introduce two generalized condensation principles: Local Club Condensation and Stationary Condensation. We show that while Strong Condensation (a generalized Condensation principle introduced by Hugh Woodin in [19]) is inconsistent with an ω1-Erdős cardinal, Stationary Condensation and Local Club Condensation (which should be thought of as weakenings of Strong Condensation) are both consiste...

Novel scaffolds are of uttermost importance for the discovery of functional material. Three different heterocyclic scaffolds easily accessible from isocyanoacetaldehyde dimethylacetal 1 by multicomponent reaction (MCR) are described. They can be efficiently synthesized by a Ugi tetrazole multicomponent reaction of 1. We discuss the synthesis, 3D structures, and other physicochemical properties.

We present a simple method for the solution of one-component and multicomponent hydrodynamic equations based on the NewtonRaphson method. We show that this method can be used for the solution of stationary hydrodynamic equations. This method has been used for the calculation of the low density stellar wind models for which the multicomponent nature of the wind influences the overall wind struct...

A heterogeneous supramolecular catalytic system for multicomponent aldol-'click' reactions is reported. The copper(I) metallohydrogel functionalized with a phenyltriazole fragment was able to catalyze the multicomponent reaction between phenylacetylene, p-nitrobenzaldehyde, and an azide containing a ketone moiety, obtaining the corresponding aldol products in good yields. A possible mechanistic...

1. Introduction Practical applications of zeolites and other nanoporous materials always involve at least two different components, but understanding of multicomponent diffusion in zeolites is limited and experimental data are scarce. The elements of the multicomponent Fickian diffusion tensor for a given system may depend on the total loading of adsorbed molecules, the adsorbed-phase compositi...

Using a combination of quantum chemistry and cluster size distribution dynamics, we study the heterogeneous nucleation n-butanol water onto sodium chloride (NaCl)10 seeds at different butanol saturation ratios relative humidities. We also investigate how is affected by seed through comparing (NaCl)5, (NaCl)10, (NaCl)25 electrical charge (Na10Cl9)+, (Na9Cl10)− seeds. Butanol common working fluid...
