Novel functional poly (ethylene terephthalate) (PET)/TiO2 nanofibers have been prepared by electrospinning the homogeneous solution of PET and titania precursor, tetra-n-butyl titanate (TBT), in trifluoroacitic acid (TFA). In situ growth of TiO2 nanoparticles in electrospun PET nanofibers has been successfully achieved via a simple hydrothermal process at low temperature. X-ray diffraction (XRD) patterns showed that the crys Read More

Nano-Au/C catalysts were prepared by loading the gold nanoparticles which were prepared by photochemical reduction method to the activated carbon. They were used for the catalytic oxidation reaction of glyoxal into glyoxylic acid. The influence of temperature and pH on the catalytic activity, and the mechanism of Au/C catalyst on catalytic oxidation of glyoxal were discussed. The amount ratio of Au: glyoxal is 1:1000; Read More

Melting processes of a truncated icosahedral Cu135 cluster have been studied by employing molecular dynamics method based on the embedded-atom method (EAM) potential. The detailed information of structure and energy changes has been obtained by dividing Cu135 cluster into six shell regions according to radical density distribution peaks of atoms. The simulation results show that the melting behavior of the Cu135 clus Read More

Gold nanoparticles(GNPs) are very suitable for the drug carrier because of their intrinsic properties. Protein- or peptide- type drugs are popular at present with their high treatments. So the research of gold nanoparticles conjunction with proteins is attractive now. In this paper, the conjunction calculated relationships between gold nanoparticles and the protein are researched. Bull Serum Albumin (BSA) and Egg White Lysozyme Read More

The WO3 nanorods and WO3·0.33H2O nanowires are fabricated by a hydrothermal method in the presence of NaCl and K2SO4, respectively. The products are characterized in detail by multiform techniques: X-ray diffraction (XRD), energy-dispersive X-ray analysis( EDS), scanning electron microscopy(SEM), and transmission electron microscopy(TEM). The WO3 nanorods have diameters ranging from 40-60 nm, and lengths Read More

Silver nanoparticles offer a broad range of applications in biomedical and bioanalytical areas. In lieu of inadequate prior reports the present study aims to investigate the differential interaction of silver nanoparticles with cysteine and glutathione. Cysteine and glutathione were chosen as the model biomolecules owing to its strong affinity towards silver nanoparticles and potential applications in the field of biomedicine. Cystein Read More

We report the shape transformation of ZnO nanorods/nanotubes at temperatures (∼700 °C) much lower than the bulk melting temperature (1975 °C). With increasing annealing temperature, not only does shape transformation take place but the luminescence characteristics of ZnO are also modified. It is proposed that the observed shape transformation is due to surface diffusion, contradicting the previously reported notion Read More

The Wiener index of a molecular graph G is defined as the summation of topological distances between all pair of atoms in G. In this paper an algorithm by Sandi Klavzar [European J. Combin. 2006, 27, 68-73] is applied to calculate the Wiener index of one-heptagonal nanocone L[n]. It is proved that W(L[n]) = (238/5)n5 + (238)n4 + (2821/6)n3 + (917/2)n2 + (3311/15)n + 42.
