Understanding solid/solid organic reactions.
The concept of an organic reaction between two macroscopic solid particles is investigated. Thus, we study several reactions that have been recently reported to proceed "in the solid phase" and clearly show that, in most cases, grinding the two solid reactants together results in the formation of a liquid phase. This is true both for catalytic transformations (e.g., aldol condensations and olig...
متن کاملSolid liquid phase changes with different densities
In this paper we present a new thermodynamically consistent phase transition model describing the evolution of a liquid substance, e.g., water, in a rigid container Ω when we freeze the container. Since the density ̺2 of ice with volume fraction β2 , is lower than the density ̺1 of water with volume fraction β1 , experiments for instance the freezing of a glass bottle filled with water show that ...
متن کاملSolid-Solid Phase Transformation Kinetics
Natural formation of the bcc modification for Co was demonstrated to occur upon precipitation of Co in supersaturated Au90Co10 alloy. The microstructural evolution was investigated by high resolution transmission electron microscopy. Co precipitation starts with the formation of very thin coherent plates along {100}Au. This initially precipitated Co was shown to be a hitherto unknown metastable...
متن کاملSolid-solid phase transition in hard ellipsoids.
We present a computer simulation study of the crystalline phases of hard ellipsoids of revolution. A previous study [P. Pfleiderer and T. Schilling, Phys. Rev. E 75, 020402 (2007)]. showed that for aspect ratios a/b>or=3 the previously suggested stretched-fcc phase [D. Frenkel and B. Mulder, Mol. Phys. 55, 1171 (1985)] is unstable with respect to a simple monoclinic phase with two ellipsoids of...
متن کاملPhase changes and chemical reactions in solid aqueous solutions: Science and technology
In recent years supersaturated solutions, especially those of carbohydrates, have been receiving increasing interest, because of their importance in natural environmental resistance mechanisms and in diverse branches of technology. The structures, dynamics and reactions in amorphous, water soluble solids are largely unexplored. Being thermodynamically unstable, such mixtures rely for their real...
