Given the continued challenge of dispersion, for practical purposes, it is of interest to evaluate the impact of multi-walled carbon nanotubes (MWCNTs) at different states of clustering on the eventual performance properties of cement paste. This study evaluated the clustering of MWCNTs and the resultant effect on the mechanical and electrical properties when incorporated into cement paste. Cem...

Thermoplastic polyolefin (TPO) has gained considerable attention because of having a combination rubbery and thermoplastic properties ease production. Their excellent weather resistance, low density, relatively cost make them attractive materials for the automotive, electrical, footwear industries membranes water treatment. main shortcomings are poor mechanical properties, especially at tempera...

Three novel hybrid materials have been synthesized by ligands: N-(2-vinylsulfanyl-ethylidene)-benzene-1,2-dimine (SBD), N-pyridin-2-ylmethylene-benzene-1,2-dimine (NBD) and N-furan-2-ylmethylene-benzene-1,2-dimine (OBD), covalently linking to multi-walled carbon nanotubes (MWCNTs). These MWCNT hybrid materials were used both as ionophores and as ion-to-electron transducers to construct Ag(+) ca...

In this study, three types of hybrid nanotubes (NTs), ie, oxidized multiwalled carbon NTs (COOH MWCNTs), heparin (Hep)-conjugated MWCNTs (Hep MWCNTs), and diblock copolymer polyglycolic acid (PGA)-co-heparin conjugated to MWCNTs (PGA MWCNTs), were synthesized with improved biocompatibility and drug-loading capacity. Hydrophilic Hep substituents on MWCNTs improved biocompatibility and acted as n...

We studied the feasibility of using halloysite clay nanotubes (HNTs) and carboxyl-functionalised multi-walled carbon nanotubes (COOH-MWCNTs) as antigen carriers to improve immune responses against a recombinant LipL32 protein (rLipL32). Immunisation using the HNTs or COOH-MWCNTs significantly increased the rLipL32-specific IgG antibody titres (p < 0.05) of Golden Syrian hamsters. None of the va...

A chemically modified graphene paste electrode was prepared by incorporating appropriate amounts of graphene in a paste mixture, followed by electrodepositing Prussian blue (PB) and coating chitosan on the electrode surface. The electrode was able to bind ssDNA, and gave a better voltammetric response for complement DNA than did ordinary carbon paste electrodes. The response of the electrode wa...

In this study, we investigated the chemical functionalization of carboxylated multiwalled carbon nanotubes (MWCNT–COOH) by 1-Amino-2-naphthol-4-sulfonic acid (ANSA). The functionalized MWCNTs exhibited good aqueous solubility due to the presence of the –OH and – SO3H groups of ANSA. The antimicrobial activity of the MWCNT–COOH as well as its functionalized multiwall nanotube MWCNT-CO-2-(1-amino...

Immunisation with the C-terminal region of leptospiral immunoglobulin-like A protein (LigANI) has shown promising results against leptospirosis. We evaluated the humoral immune response and protection induced by LigANI associated with carboxyl multi-walled carbon nanotubes (COOH-MWCNTs), CpG oligodeoxynucleotides (CpG ODNs), or Alhydrogel. Animals immunised with CpG ODNs were unable to develop ...

in this paper, the electrochemical hydrogen storage in nanocomposite materials was studied. multi-walled carbon nanotubes (mwcnts) electrode was prepared by mixing with special composite. the optimum ratio of mwcnts was estimated 30-70% (w/w) in the composite material. mwcnts were synthesized by chemical vapor deposition (cvd). the nanocomposite was homogenized by microwave. cyclic voltammetry ...

Lithium-sulfur batteries have attracted great attention because of their high energy density, environmental friendliness, natural abundance and intrinsically low cost of sulfur. However, their commercial applications are greatly hindered by rapid capacity decay due to poor conductivity of electrode, fast dissolution of the intermediate polysulfides into the electrolyte, and the volume expansion...
