Designing multi-component molecular crystals: a crystal engineering approach

Crystal Engineering Studies: polymorphs and co-crystals

We review the key topics of one of the areas with the biggest impact of the last years in the chemical and pharmaceutical industry that is Crystal Engineering. The relevance of polymorphs and co-crystals from different points of view is been highlighted and broadly illustrated by means of several recent examples of studies carried out in this field. In addition, the most suitable instrumental t...

Multi-component vector solitons in photorefractive crystals

We study the existence and stability of multi-component spatial optical solitons in anisotropic nonlocal photorefractive media. For the case of three components, we find numerically the whole family of composite solitons with two perpendicular dipole components, and show their stability for a wide range of parameters. We confirm our theoretical results by an experimental observation of these no...

Designing a Component Store for Chemical Engineering Software Solutions

In the Global Cape Open project of the G7 Intelligent Manufacturing Systems (IMS) program, the worldwide chemical industries have defined an open standard for chemical engineering simulation software. This opens up a market for simulation components representing the structure and behavior of specialized processing units for small enterprises and research institutions. This paper describes the r...

Engineering molecular crystals with abnormally weak cohesion.

Adding astutely placed methyl groups to hexaphenylbenzene increases molecular weight but simultaneously weakens key C-H···π interactions, thereby leading to decreased enthalpies of sublimation and showing that materials with abnormally weak cohesion can be made by identifying and then obstructing interactions that help control association.
