Green conversion of hazardous red mud into diagnostic X-ray shielding tiles.

Red mud is a solid hazardous alumina industrial waste, which is rich in iron, titanium, aluminum, silicon, calcium, etc. The red mud contains 30-60% of hematite, which is suitable for shielding high energy X- and gamma rays. So, the iron rich red mud was converted into diagnostic X-ray shielding tiles through ceramic route by adding a certain weight percentage of BaSO and binders (kaolin clay or sodium hexametaphosphate) with it.

CuO Nanoparticles/Multi-Walled Carbon Nanotubes (MWCNTs) Nanocomposites for Flexible Supercapacitors.

Copper oxide nanoparticles (CuO NPs)/multi-walled carbon nanotube (MWCNTs) nanocomposites were synthesized by a simple co-precipitation technique. MWCNTs networks acted as an ideal supporter for active material and permitted formation of free standing hybrid nanocomposite in the sheet form. Structural properties of CuONPs/MWCNTs nanocomposites were examined using X-ray diffraction (XRD), X-ray photon spectroscopy (XPS) and Transmission electron microscopy (TEM).

Fabrication and Characterization of Flexible Cotton Fabric/Carbon Nanotubes/MnO₂ Nanocomposite-Based Electrodes for Energy Storage Application.

Flexible cotton fabric based electrodes were fabricated using multi-walled carbon nanotubes (MWCNTs) and manganese dioxide (MnO₂) nanocomposite which was prepared using wet chemical synthesis. Characterization of CNT/MnO₂ nanocomposite was done by Transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photon spectroscopy (XPS), Raman spectroscopy and BET analysis. Their electrochemical properties were investigated using three electrode systems.
