Black titania nanotubes/spongy graphene nanocomposites for high-performance supercapacitors.

A simple method is demonstrated to prepare functionalized spongy graphene/hydrogenated titanium dioxide (FG-HTiO) nanocomposites as interconnected, porous 3-dimensional (3D) network crinkly sheets. Such a 3D network structure provides better contact at the electrode/electrolyte interface and facilitates the charge transfer kinetics. The fabricated FG-HTiO was characterized by X-ray diffraction (XRD), FTIR, scanning electron microscopy (FESEM), Raman spectroscopy, thermogravimetric analysis (TGA), UV-Vis absorption spectroscopy, and transmission electron microscopy (TEM).

Adenine-functionalized Spongy Graphene for Green and High-Performance Supercapacitors.

A simple method is demonstrated to prepare spongy adenine-functionalized graphene (SFG) as interconnected, porous 3-dimensional (3D) network crinkly sheets. Such 3D network structure provides better contact at the electrode/electrolyte interface and facilitates the charge transfer kinetics. The fabricated SFG was characterized by X-ray diffraction (XRD), FTIR, scanning electron microscopy (FESEM), Raman spectroscopy, thermogravimetric analysis (TGA), UV-vis absorption spectroscopy, and transmission electron microscopy (TEM).

Mesoporous Alumina Nanoparticles as Host Tunnel-like Pores for Removal and Recovery of Insecticides from Environmental Samples.

Water contamination with lindane, which is a persistent, toxic, and priority insecticide, is a major problem worldwide. This study presents the fabrication of mesoporous alumina nanoparticles (MA-NPs) with a large surface-area-to-volume ratio, active surface sites, and open channel pores to trap/adsorb insecticide molecules, such as lindane. Key factors, such as temperature, pH (i.
