The precipitation of chromium(III), copper(II), manganese(II) and zinc(II) by biogenic hydrogen sulfide generated by sulfate-reducing bacteria, Desulfovibrio sp., and the degradation of total petroleum hydrocarbons (TPH) in the presence of heavy metal by Pseudomonas aeruginosa AT18 have been carried out. An anaerobic stirred tank reactor was used to generate hydrogen sulfide with Desulfovibrio ...

Nano sized ZnS and MnS2 were synthesized through a simple wet chemical route. In this Synthesis metal sulfides were used as the starting material and allowed to react with the transition metal source at 60°C for 75 minutes. The products were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Photoluminescence spectra (PL), Raman Spectra, Thermogravimetry analysis Diff...

Bu çalışmada, Ni(II)Pc (nikel(II)ftalosiyanin) ve CdSeS/ZnS (cadmium selenide sulfide/zinc sulfide) kuantum nokta katkılı 5CB (4-pentyl-4′-cyanobiphenyl) nematik sıvı kristal kompozit yapıların dielektrik özellikleri ile birlikte bu özelliklerin makine öğrenmesi algoritmaları tahminlenmesi rapor edilmektedir. Konsantrasyon oranının özelliklere etkilerini saptamak için yapıya ağırlıkça %2 %5 ora...

We report an inexpensive TiO2 based quantum dot solar cell (QDSSC) with improved power conversion efficiency prepared by simple techniques. Barium doped zinc sulfide has been successfully deposited on cadmium dots (QDs) successive ion layer adsorption and reaction (SILAR) technique. The is utilized as a passivation in the QDSSC, which helped better charge separation. copper (Cu2S) reduced graph...
