In this study the "green chemistry" use of the biosurfactant surfactin for the synthesis of calcium phosphate using the reverse microemulsion technique was demonstrated. Calcium phosphates are bioactive materials that are a major constituent of human teeth and bone tissue. A reverse microemulsion technique with surfactin was used to produce nanocrystalline brushite particles. Structural diversi...

In this work we report the synthesis, microstructure, electric properties and sensing performance of BaSnO3 (BS) powder, it was prepared by mechano-chemical method. As prepared powder is calcinated at temperatures 1100 o C, and 1300 o C tested for crystallization. Thick films were prepared using simple screen-printing technology. Structural and electrical analyses were performed and the results...

This paper describes a reliable and sensitive method for sensing dissolved acetone using doped nanomaterials. Large-scale synthesis of ZnO nanorods (NRs) doped with Co3O4 was accomplished by a solvothermal method at low temperature. The doped NRs were characterized in terms of their morphological, structural, and optical properties by using field-emission scanning electron microscopy coupled wi...

The supplementary data have included a full range of TEM pictures of the post-run samples, including 400 oC calcinated MoO3/H-ZSM-5 samples (coked) and the parent H-ZSM-5 (coked), showing the distribution of Mo clusters on the zeolite crystallite external surface, and the observed coke deposition upon the spreading of the Mo species. The Figures S1-S9 are the complementary of the Fig. 8 in the ...

Tungsten oxide (WOx) has been widely studied for versatile applications based on its photocatalytic, intrinsic catalytic, and electrocatalytic properties. Among the several nanostructures, we focused on the flower-like structures to increase the catalytic efficiency on the interface with both increased substrate interaction capacities due to their large surface area and efficient electron trans...

More than 80% of the world’s production of zinc from its concentrate is obtained by the roastleach-electrowin hydrometallurgical process. In the roast-leach process, very pure zinc sulphate solution must be prepared for zinc electrowinning, therefore, the purification process is one of the most important unit processes in zinc hydrometallurgy. The conventional methods for the zinc solution puri...

In this work, limestone-calcined clay (LC2) is studied as an alternative supplementary cementitious material (SCM), combining two widely available resources – calcinated kaolinitic and limestone, to partially substitute portland clinker. The primary goal assess the potential of LC2 produce moderate high strength concretes with design compressive strengths 20 50 MPa. For purpose, 27 mixes were p...

In this work firstly Fe3O4 nanoparticles were synthesized via a sono-chemical method. At the second step magnesium hydroxide shell was synthesized on the magnetite-core under ultrasonic waves. For preparation Fe3O4-MgO the product was calcinated at 400 ºC for 2h. Properties of the product were examined by X-ray diffraction pattern (XRD), scanning electron microscope (SEM) and Fourier transform ...

The synthesis of pharmaceutically and biologically active 2-amino-4H-chromenes was described using TiO2/nanoclinoptilolite (TiO2/NCP) as an efficient nanocatalyst under solvent-free condition. The TiO2/NCP was fabricated through modification of NCP with HDTMA, then the surface modified NCP was impregnated with titanium tetrachloride solution. Finally, the materi...
