Physical origin of the high energy optical response of three-dimensional photonic crystals [PDF]
The physical origin of the optical response observed in three-dimensional photonic crystals when the photon wavelength is equal or lower than the lattice parameter still remains unsatisfactorily explained and is the subject of an intense and interesting ...

Abstract This publication presents the geometries of 157 nitro‐ and polynitropyrazoles. Among these, 109 compounds were theoretically studied using mainly the B3LYP/6–311++G(d,p) level of theory. Three‐parameter Lee‐Yang‐Parr (B3LYP) is a density functional theory (DFT) method widely used in computational chemistry and constitutes an acceptable ...

Synthesis of Crosslinked Biopolyesters Catalyzed by Natural Amino Acids
Highly crosslinked bio‐polyesters were synthesized via the ROCOP reaction between epoxidized sunflower oil and biobased cyclic anhydrides. The resulting materials were comprehensively characterized by FT‐IR, TGA, and DSC. A cross‐linked network in the bio‐based polymers has been confirmed by dynamic mechanical analysis.
