Coarse grained molecular dynamics simulations are presented in which the sensitivity of the ice nucleation rate to the hydrophilicity of a graphene nanoflake is investigated. We find that an optimal interaction strength for promoting ice nucleation exists, which coincides with that found previously for a face centered cubic (111) surface. We further investigate the role that the layering of int...

Nucleation and crystallization from xerogels of the system Si02-ZnOA1203 are induced and probed by Cr. Besides the traditional techniques, such as X-ray diffraction, SAXS and TEM, ESR and optical techniques especially laser spectroscopy are employed for the investigation of the structural evolution during thermal treatments of these xerogels. Cr is served not only as a structure probe but also ...

Composites based on green high-density polyethylene (G-HDPE) and hydroxyapatite (HA) compatibilized with maleic anhydride grafted (HDPE-g-MAH) were developed in this work. The main objective was to evaluate the effects of HA HDPE-g-MAH contents mechanical thermal properties hydrolytic degradation composites through design experiments statistical analysis, as well hemolytic stability. Hydroxyapa...
