Carbon Nanofibers Properties and Specifications

Carbon nanofibers (CNFs) are long, fibrous carbon layers of a platelet type - perpendicularly arranged individual layers to the fiber axis or of herringbone type - nested inside one another at an angle. The arrangement is determined depending on the catalyst used Carbon nanofibers (CNFs) are in a class of one-dimensional carbonaceous materials with exceptional electronic conductivity, which made them a perfect use as conductive additives in electrode materials for lithium-ion batteries and sodium-ion batteries.
When Carbon nanofibers (CNFs) are used explicitly as anode materials for production of numerous intercalation sites, they show excellent performance of sodium and lithium storage. For non-carbon electrodes of lithium-ion & sodium-ion, Carbon nanofibers (CNFs) can function as electron conducting and porous substrates enhancing the overall electronic & ionic conductivity alongside with stabilization of the electrode structures during cycling, causing the improvement of the non-carbon anode and cathode materials’ electrochemical performance.
Since Carbon nanofibers (CNFs) do have irregular surface structure, with many corners and edges, it makes them an ideal material for fast adsorption/desorption processes. Carbon nanofibers (CNFs) are also often used as a nanostructured catalyst and catalyst carrier. Especially due to the combination of catalytic activity with their inherent excellent electrical and thermal conductivity, they open attractive possibilities for use in catalytic processes. Also the platelet type Carbon nanofibers (CNFs) are used in self-lubricating materials.
Carbon nanofibers (CNFs) are produced catalytically in the CVD process. Carbon nanofibers (CNFs) undergo the process of synthesis by co-catalyst deoxidization process by a reaction between C2H5OC2H5, Zn and Fe powder at 650 °C for 10 h. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy indicate that as-prepared CNFs possess low graphitic crystallinity. The resultant CNFs as electrode shows capacity of ∼220 mAh/g and high reversibility with little hysteresis in the insertion/deintercalation reactions of lithium-ion.

While having similar ratio of length to diameter (aspect ratio) to that of the carbon nanotubes still, they are significantly larger, normally having a diameter ranging between 150–300 nm.In case metallic intermediate layers are applied between the graphene layers the material shows an improvement in the binding of Carbon Nanofibers (CNFs) to ceramic and metallic matrices. This modification makes the nanofibers suitable for the use in composite materials.

Cadmium Sulfide Nanopowder and Its Applications

Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite. As a compound that is easy to isolate and purify, cadmium sulfide the principal source of cadmium for all commercial applications. Its vivid yellow color led to its adoption as a pigment for the yellow paint "cadmium yellow" in the 18th century. Cadmium Sulfide Nano Powder, CdS (99.9+%, 20 nm)  shows unique physical, chemical and structural properties from the bulk. The melting point, electronic absorption spectra, band gap energy crystal structure, and other properties of cadmium sulfide nanoparticles are affected by size.

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
