In this work, black nanocarbon-loaded 0–100 parts-per-hundred (phr) PbO-filled acrylonitrile butadiene rubber (NBR)/styrene-butadiene (SBR) blend composites were prepared by using an ordinary standard mixer. Both mechanical and gamma attenuation properties of the samples investigated. Maximum tensile strength elongation at break obtained 40 phr PbO concentration. The values for mass coefficient...
Although lithium-ion batteries are traditionally considered to be the most promising candidate for electrochemical energy storage owing to their relatively long cycle life and high energy efficiency, their limited energy density as well as high cost are still causing a bottleneck for their long-term applications. Alternatively, rechargeable Li-O2 batteries have the potential to practically prov...
Nanocarbon is a promising type of biomaterial for diagnostic and therapeutic applications. Fluorescent nanodiamond (FND) containing nitrogen-vacancy centers as built-in fluorophores is a new addition to the nanocarbon family. Here, we study the long-term stability and biocompatibility of 100-nm FNDs in rats through intraperitoneal injection over 5 months and develop the potential application of...
Charge transfer at metallo-molecular interfaces may be used to design multifunctional hybrids with an emergent magnetization that may offer an eco-friendly and tunable alternative to conventional magnets and devices. Here, we investigate the origin of the magnetism arising at these interfaces by using different techniques to probe 3d and 5d metal films such as Sc, Mn, Cu, and Pt in contact with...
In this study, we investigated the toxic effects of nanocarbon blacks (NCBs) with different sizes to mouse macrophage RAW264.7 cells. MTT and fluorescence-based LIVE assays demonstrated that NCBs uptake caused a size and dose-dependent growth inhibition to the cells. Optical microscopy observations and (99m)Tc radionuclide labeling techniques were used to investigate the cellular uptake of NCBs...
Room temperature electrochemical deposition of transition metal chalcogenide (MoSx) on 3D-printed nanocarbon fibers based electrodes for custom shaped solid-state supercapacitor.
recent development of carbon nanotubes materials as counter electrode for dye-sensitized solar cells
dye-sensitized solar cells present promising low-cost alternatives to the conventional silicon (si)-based solar cells. the counter electrode generally consists of pt deposited onto fto plate. since pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. carbon nanotubes have shown significant properties such...
