The present invention applies carbon nanotubes to catalyst particles, thereby providing catalyst particles which are usable in fluidized bed reactions, have high catalytic activity, and are easy to handle. The catalyst particles are carbon nanotube-coated catalyst particles which each comprise a carrier particle and a coating layer disposed on the surface of the carrier particle, wherein the carrier particles are flowable in fluidized beds and the coating layer comprises carbon nanotubes which have metal nanoparticles supported thereon and/or which have been doped with nitrogen or boron. The carbon nanotube-coated catalyst particles are flowable in fluidized bed reactions.

Stem cell, bone and nerve scaffolding comprising discrete carbon nanotubes is disclosed. The discrete carbon nanotubes may be have targeted, or selective oxidation levels and/or content on the interior and exterior of the tube walls. The described scaffolding may be used to guide, target and protect stem cells upon injection into the body.

A foam structure with nominally aligned arrays of carbon nanotube is described. The foam structure also includes a functionalization substance associated or attached to carbon nanotube surfaces.

The method for producing noble metal nanocomposites involves reducing noble metal ions (Ag, Au and Pt) on graphene oxide (GO) or carbon nanotubes (CNT) by using Artocarpus integer leaves extract as a reducing agent. As synthesized MNPs/GO and MNPs/CNT composites have been characterized using X-ray diffraction (XRD), transmission electron microscope (TEM) imaging, and energy dispersive X-ray spectroscopy (EDX). The TEM images of prepared materials showed that the nanocomposites were 1-30 nm in size with spherical nanoparticles embedded on the surface of GO and CNT. This synthetic route is easy and rapid for preparing a variety of nanocomposites. The method avoids use of toxic chemicals, and the prepared nanocomposites can be used for biosensor, fuel cell, and biomedical applications.

A modified super-hydrophobic material-coated high-nickel cathode material for a lithium ion battery and a preparation method therefor. The surface of the high-nickel cathode material for a lithium ion battery is coated with a modified super-hydrophobic material, and particles are bridged with each other by the modified super-hydrophobic material. The modified super-hydrophobic material is obtained by depositing a nano material on the surface of a super-hydrophobic material. By the surface modification of the super-hydrophobic material, the hydrophobic and electrolyte-philic properties and the conductivity of the super-hydrophobic material are improved. Next the modified super-hydrophobic material is coated on the surface of the particles of the high-nickel cathode material for a lithium ion battery and between the particles, in the form of a three dimensional network. Thus the surface hydrophobic conductive treatment of the high-nickel cathode material is effectively realized; reducing the reaction of environmental water with surface free lithium and side reactions of trace water and an electrolyte, and improving the safety, cycle and storage performance of the high-nickel cathode material for a lithium ion battery in batteries.
