The removal of dyes from wastewater is an important topic in environmental applications. Methylene blue (MB) one the most worrisome compounds, as it widespread and used many industrial activities. Adsorption represents effective technique for this contaminant. Thermo plasma expanded graphite (TPEG) material characterized by a fibrous morphology, very low density overlapped graphene layers. TPEG...

A paraffin-Compressed Expanded Natural Graphite (CENG) composite encapsulated in aluminium shell has been thermally aged a packed bed heat storage tank. hydraulic test settled order to impose 8500 thermal cycles where the material underwent phase change at each cycle. The PCM provokes an expansion of structure that might affect effective conductivity and then transfer rate Thermal Energy Storag...

By using 1,5-pentanediol as a capping and structure directing agent, ultrathin Eu2O3 nanosheets (<1 nm) have been synthesized and assembled into a layered structure. The lateral dimensions of the nanosheets can be tuned by simply controlling the reaction time. These layered structures exhibit a strong quantum size effect due to the extremely small thickness of the assembled nanosheets.

Through density functional theory computations, we systematically investigated the structural, electronic, and magnetic properties as well as the relative stabilities of fully and partially hydrogenated ZnO nanosheets. Unlike bare ZnO nanosheets terminating with polar {0001} surfaces, their hydrogenated counterparts preserve the initial wurtzite configuration. Full hydrogenation is more favorab...

Z-scheme heterojunction was successfully constructed with (001)-TiO2 and g-C3N4 via electrostatically self-assemble. Z-Scheme nanocomposites improve separation efficiency of photogenerated e?-h+ pairs, which strengthen visible photocatalytic elimination for Rhodamine B. The narrower bandgap not only forms a stable phase interface (001)-faceted TiO2 nanosheets, but also provides high productivit...

Copper based ternary and quaternary semiconductor nanostructures are of great interest for the fabrication of low cost photovoltaics. Although well-developed syntheses are available for zero dimensional (0D) nanoparticles, colloidal synthesis of two dimensional (2D) nanosheets remains a big challenge. Here we report, for the first time, a simple and reproducible cation exchange approach for 2D ...

We report the preparation of monometallic Co(2+)/Co(3+) layered double hydroxide, intercalated with lactate anions (LCoH-Lactate), and its spontaneous delamination in water to form cobalt hydroxide nanosheets. These hydroxide nanosheets formed stable aqueous dispersions. The thickness of a nanosheet was estimated to be approximately 1 nm by atomic force microscopy and small angle X-ray scatteri...
