Cubic Structure

A new approach to the investigation of the proton-disordered structure of clathrate hydrates is presented. This approach is based on topological crystallography. The quotient graphs were built for the unit cells of the cubic structure I and the hexagonal structure H. This is a very convenient way to represent the topology of a hydrogen-bonding network under periodic boundary conditions. The exact proton configuration statistics for the unit cells of structure I and structure H were obtained using the quotient graphs. In addition, the statistical analysis of the proton transfer along hydrogen-bonded chains was carried out.

Main Influence

ABSTRACTIn this work, green nanotechnology has been applied by using phytochemical compounds as reducing agents from the plant extract of Hydrocotyle ranunuculoides through three modifications of the phytosynthesis method to prepare Fe and Zn nanoparticles, in three different concentration of the metallic solution. In the third modification a MgO support was included to avoid the Fe and Zn NP agglomeration. The nanoparticles size was 5±1 nm, and for the Fe NPs, it was determined with a cubic structure a Fe3O4 composition, and Zn nanoparticles were obtained with a hexagonal structure and Zn° composition. In the third method, MgO nanoparticle, the support appears as Mg0 nanoparticles surrounded by Fe0 and Zn0 nanoparticles. According to the three used methods pathways, the main influence is the modification in the method synthesis. Hybrid nanocomposites provide a means in preventing agglomeration of the NPs and hence avoid coalescence and loss of properties.
