Photonic crystals with nanocelulose

Picard G., Simon D., Kadiri Y., Lebreux J.-D., Gozayel F., College Ahuntsic, CA

Nano Crystalline Cellulose (NCC) can be easily extracted from wood. This has been known for several decades (see for modern extraction method the reference 1). It was also demonstrated for decades that letting the dispersion [...]

Nano Crystalline Cellulose – Optical and Structural Properties by Molecular Dynamic Simulations

Kadiri Y., Simon D., Picard G., Ghozayel F., Lebreux J.-D., Ahuntsic College, CA

Structural and optical properties of Nano Crystalline Cellulose (NCC) in liquid solutions and in nematic films were investigated by large-scale molecular dynamics (MD) simulation using empirical Coulombian interaction potentials. The latter was modified by taking [...]

Nano Crystalline Cellulosic Nematic monocrystals optical properties

Picard G., Kadiri Y., Simon D., Ghozayel F., Lebreux J.-D., Ahuntsic College, CA

Magnificent opalescent effects are observed from the interaction between light and Nano Crystalline Cellulose (NCC). Leaving a thin liquid NCC suspension to slowly evaporate, a dry polycrystalline nematic cholesteric wafer was obtained. It was observed [...]
