• A comparative study on two different methods for calculating gravity effect of an uneven layer: Application to computation of bouguer gravity anomaly in the east Vietnam sea and adjacent areasA comparative study on two different methods for calculating gravity effect of an uneven layer: Application to computation of bouguer gravity anomaly in the east Vietnam sea and adjacent areas

    Abstract: Calculation of gravity anomaly caused by an uneven layer is essential for quantitative interpretation. By comparing calculated anomalies with observed anomalies, we may infer some parameters of subsurface structures. There are many different methods for computing gravity effect of an uneven layer. This paper presents a comparative stud...

  • Nano titanium dioxide coated on multi-wall carbon nanotubes for photocatalytic applicationNano titanium dioxide coated on multi-wall carbon nanotubes for photocatalytic application

    Abstract. Titanium dioxide (TiO2) coated on multi-walled carbon nanotubes (CNTs) was synthesized with CNTs and TiO2 using the grinded method. The XRS spectra include that of the obtained single-phase anatase sample. The UV-Vis diffuse reflectance spectra show that the composite material can absorb at a higher wavelength and the absorption covers...
