There is a compelling reason to design cost-effective sensors detect and measure harmful molecules such as dichlorosilane (H 2 SiCl ) in the air. In this work, density functional theory (DFT) has been used study nature of intermolecular interactions between H gas molecule with single-walled pristine, Al-doped, Ga-doped boron nitride nanotubes (BNNT, BNAlNT, BNGaNT, respectively) investigate the...

Doped lanthanum phosphate nanocrystals are a class of fluorescent material of enormous interest, presenting an unusual dichotomy on the nanoscale. The quantum yields of these crystals drops significantly in the nanoscale when compared with the corresponding bulk yields. Herein we show that the suppression of their thermodynamically favored 1-D growth in the nanoscale results in an increase in t...

’ INTRODUCTION Since the discovery of carbon nanotubes, hollow nanotubes have attracted considerable attention due to their functional significance and potential applications in nanoscale devices, sensors, and energy storage/conversion. In particular, silica nanotubes raise special interest because of their biocompatibility, confined environment as nanocontainers, and feasibility of chemical mo...

In this study, incorporation of iron ion-doped natrolite nanozeolite, multi-wall carbon nanotubes into chitosan-coated glassy carbon electrode for the simultaneous determination of ascorbic acid, epinephrine, uric acid and tyrosine is studied. The results show that the combination of multi-wall carbon nanotubes and iron ion-doped natrolite zeolite causes a dramatic enhancement in the sensitivit...

Using facile diazonium chemistry, sulfonate groups have been covalently attached to single wall carbon nanotubes. The resulting sulfonated tubes form a stable aqueous dispersion in the presence of pyrrole monomer. Subsequent electropolymerisation results in a conductive, electroactive polypyrrole doped with sulfonated tubes being formed at unusually low potentials. The potential of this materia...

Nitrogen-doped carbon nanotubes decorated with Co and Ni metal nanoparticles were assessed as counter electrodes (CEs) of dye-sensitized solar cells (DSSCs). These composites show good electrocatalytic activity toward the counter electrode reduction reaction (I3(-)→ I(-)) in DSSCs. The resulting devices using these composites as CEs display photovoltaic performance as good as, or even better th...

The oxidations of formate and methanol on nitrogen-doped carbon nanotubes decorated with palladium nanoparticles were studied at both the single-nanotube and ensemble levels. Significant voltammetric differences were seen. Pd oxide formation as a competitive reaction with formate or methanol oxidation is significantly inhibited at high overpotentials under the high mass transport conditions ass...

One-dimensional (1D) systems face some obstructions that prevent the emergence of superconductivity, such as Tomonaga-Luttinger liquid states and Peierls transition. Carbon nanotubes (CNs) are one of the best candidates for investigating the possibility of 1D superconductivity and its interplay with such obstructions. Only two groups to our knowledge, however, have experimentally reported super...
