Películas delgadas de Bi2(SxSe1-x)3 fueron obtenidas por el método SILAR a partir soluciones precursoras Bi(NO3)3, C2H5NS y Na2SeSO3. La composición las películas se modificó mediante la razón S:Se, variando concentración precursoras. Las sometidas tratamiento térmico 300*C en vacío. caracterizaciones estructurales, morfológicas, ópticas eléctricas llevadas cabo. Se obtuvieron cristalinas que c...

For photovoltaic applications, undoped and Ni2+ doped Bi2S3 thin films were chemically deposited onto glass substrates at room temperature. Elemental diffraction analysis confirmed the successful incorporation in range of 1.0 to 2.0 at. %, while X-ray Diffraction revealed that orthorhombic crystal lattice was conserved transferring from binary ternary phase. Scanning electron microscopy images ...

The use of copper anode slime (CAS) for the removal lead, bismuth, and arsenic is key to recovering precious metals. In this paper, vacuum differential gravimetry experiments combined with thermodynamic equilibrium calculations reveal effects temperature, system pressure, carbon concentration on interactions among Pb, Bi, As during reduction. content a direct factor limiting reduction reactions...
