Crystal engineering. From molecules to crystals [PDF]

open access: yesActa Crystallographica Section A Foundations of Crystallography, 2011
How do molecules aggregate in solution, and how do these aggregates consolidate themselves in crystals? What is the relationship between the structure of a molecule and the structure of the crystal it forms? Why do some molecules adopt more than one crystal structure? Why do some crystal structures contain solvent?

The Ladder Crystal [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2009
In this paper, we introduce a new model of the crystal $B(\Lambda _0)$ of $\widehat{\mathfrak{sl}_{\ell}}$. We briefly describe some of the properties of this crystal and compare it to the combinatorial model of Misra and Miwa. Dans cet article on propose un nouveau modèle du cristal $B(\Lambda _0)$ de \$\widehat{\mathfrak{sl}_{\ell}}$.

Orientation and Temperature Dependence of Piezoelectric Properties for Sillenite-Type Bi12TiO20 and Bi12SiO20 Single Crystals

open access: yesCrystals, 2014
The full matrix of electro-elastic constants of sillenite-type crystals Bi12TiO20 (BTO) and Bi12SiO20 (BSO) were determined by the resonance method, with d14 and k14 being on the order of 40–48 pC/N and 31%–36%, respectively.
