Shape memory nanocomposites are excellent smart materials which can switch between a variable temporary shape and their original upon exposure to external stimuli such as heat, light, electricity, magnetic fields, moisture, chemicals, pH, etc. Numerous nanofillers have been introduced in polymers carbon nanotubes, graphene, nanodiamonds, nanofibers, Among nanocarbons, graphene has attracted res...

Combination of an oxide semiconductor with a highly conductive nanocarbon framework (such as graphene or carbon nanotubes) is an attractive avenue to assemble efficient photoelectrodes for solar fuel generation. To fully exploit the possible synergies of the hybrid formation, however, precise knowledge of these systems is required to allow rational design and morphological engineering. In this ...

The expansion product from the sulfuric acid dehydration of para-nitroaniline has been characterized and studied for CO2 adsorption. The X-ray photoelectron spectroscopy (XPS) characterization of the foam indicates that both N and S contents (15 and 9 wt%, respectively) are comparable to those separately reported for nitrogenor sulfur-containing porous carbon materials. The analysis of the XPS ...

Find out main factor influencing improved electrochemical performance. Key role of oxidation undergone by fibers during EPD. The energy efficiency vanadium flow batteries (VRFB) greatly depends on performance that constitute these devices, s...

Waste cooking oil, a known environmental pollutant, has been used as precursor for the synthesis of onion-like nanocarbons (OLNCs) using flame pyrolysis. The OLNCs were added to TiO2 form TiO2/OLNC nanocomposites through hydrothermal treatment. TiO2/OLNCs ratio was varied by increasing mass (10, 20, 30, and 50 mg), while (100 mg) kept constant at C molar ratios 1:2, 1:4, 1:6, 1:10, respectively...

This study describes a world of new carbon “fullerene” allotropes that may be synthesized by molten carbonate electrolysis using greenhouse CO2 as the reactant. Beyond conventional diamond, graphite and buckyballs, vast array unique nanocarbon structures exist. Until recently, was thought to unreactive. Here, we show can transformed into distinct nano-bamboo, nano-pearl, nano-dragon, solid holl...

Nanocarbons, especially carbon nanotubes and nanofibers CNTs/CNFs), are key materials in nanoscience and nanotechnology, but their application on a large scale (for instance in catalysis) is limited by their difficult production. Current processes including preparation of the support, normally silica or alumina, and impregnation with catalytically active metal for hydrocarbon decomposition, are...
