Solid-Solid Transformation in Racemic Ibuprofen

Pharmaceutical Research, 2012
To clarify the polymorphism of racemic Ibuprofen and to determine the kinetic of the phase transformation that follows crystallisation of phase II.Differential Scanning Calorimetry (DSC), X-ray powder diffraction and Hot Stage Microscopy are complementarily used to perform a kinetic investigation of the particular temperature range where competition ...

Solid/Solid Adsorption

1985
We have found experimentally that many solids can disperse spontaneously onto supports to form a monolayer or submonolayer. This is a quite widespread phenomenon) which has not been recognized before. We call it solid/solid adsorption. This phenomenom may be attributed to the formation of strong surface bonds between the atoms, ions or molecules of ...

Understanding Solid/Solid Organic Reactions

Journal of the American Chemical Society, 2001
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.

Enzymatic Solid-to-Solid Peptide Synthesis

2003
Solid-to-solid peptide synthesis is an enzyme-catalyzed reaction carried out in a mixture consisting of solid substrates and up to 20% (w/w) of enzyme solution in water. No organic solvents are necessary for the preparation of the initial reaction mixtures.

Growth in a restricted solid-on-solid model

Physical Review Letters, 1989
Extensive simulations of growth in a stochastic ballistic deposition model on a (d-1)-dimensional substrate with a constraint on neighboring interface heights are described. The interface width obeys scaling even for small systems and grows as ${t}^{\ensuremath{\beta}}$ with \ensuremath{\beta}=1/(d+1). Generalizations to include irrevelant effects such

Catalytic growth of nanowires: Vapor–liquid–solid, vapor–solid–solid, solution–liquid–solid and solid–liquid–solid growth

Current Opinion in Solid State and Materials Science, 2006
Catalytic growth is a powerful tool to form a variety of wire (whisker) like structures with diameters ranging from just a few nanometres to the millimetre range. A range of phases (gas, solid, liquid, solution and supercritical fluid) have been used for the feeder phase, i.e. the source of material to be incorporated into the nanowire.

Solid-To-Solid Adhesion

1966
The term solid-to-solid adhesion means different things to different people. Although there is no hope of satisfying everybody, it will be attempted to tell as much about it as is possible. We will start with an experiment, using as a solid a piece of chalk.
