The N, S-co-doping of commercial carbon nanotubes (CNTs) was performed by a solvent-free mechanothermal approach using thiourea. CNTs were mixed with the S-dual precursor in ball-milling apparatus, and further thermally treated under inert atmosphere between 600 1000 °C. influence temperature applied during thermal procedure investigated. Textural properties materials not significantly affected...

The structure and distribution of organic sulfur in coals of different rank and different sulfur content were studied by combining mild organic solvent extraction with XPS technology. The XPS results have shown that the distribution of organic sulfur in coal is related to the degree of metamorphism of coal. Namely, thiophenic sulfur content is reduced with decreasing metamorphic degree; sulfoni...

Efficient generation of 1O2 nonradical species from persulfate (PS) is demonstrated during heterogeneous catalysis systems based on the use new Nitrogen and Sulfur doped carbons (NC, SC NSC), as prepared by direct carbonization polyaniline/polythiophene conjugated polymers at 800 °C. Complete organic molecules degradations were achieved with high mineralization rate (?70%) for all systems, over...

This article presents the results of experimental and theoretical studies of the v(O-H) and v(O-D) band shapes in the polarized infrared spectra of 3-thiophenic acid crystals measured at room temperature and at 77 K. The line shapes are studied theoretically within the framework of the anharmonic coupling theory, Davydov coupling, Fermi resonance, direct and indirect damping, as well as the sel...

UNLABELLED BACKGROUND The desulphurization of dibenzothiophene (DBT), a recalcitrant thiophenic fossil fuel component by Serratia marcescens (UCP 1549) in order for reducing the Sulphur content was investigated. The Study was carried out establishing the growth profile using Luria Bertani medium to different concentrations of DBT during 120 hours at 28°C, and orbital Shaker at 150 rpm. RES...
