[GaF(H2O)][IO3F]: a promising NLO material obtained by anisotropic polycation substitution

On Infinite Words Obtained by Selective Substitution Grammars

We present a method of generating infinite words from selective substitution grammars introduced by Rozenberg (1977). Comparison is made with some of the well-known limiting processes and limit language families and certain closure properties are examined. A technique is given for obtaining infinite non-repetitive words. Several decidability results are established.

The isotropic material closest to a given anisotropic material

The isotropic elastic moduli closest to a given anisotropic elasticity tensor are defined using three definitions of elastic distance, the standard Frobenius (Euclidean) norm, the Riemannian distance for tensors, and the log-Euclidean norm. The closest moduli are unique for the Riemannian and the log-Euclidean norms, independent of whether the difference in stiffness or compliance is considered...

Studies on L-valinium Picrate Single Crystal: A Promising NLO Crystal

L-valinium picrate, an organic material, was synthesized and grown by solution growth method. Cell parameters of the grown crystals were obtained from the single crystal X-ray diffraction analysis and the presence of functional groups was identified by FTIR study. The quality of the crystal was also examined by high-resolution X-ray diffraction study. Its optical properties were examined by UV-...
