Nanofibers have great importance in the membrane technology used hydrophobic surface filtration studies applied to water-oil separation products. This study improves upon properties of electrospun polystyrene-based nanofibers by increasing contact angles. As a result, been produced adding ZnO, MoO3, NiO, SiO2, and TiO2 additives polystyrene (PS)/dimethylformamide (DMF) polymer solution at 5% ma...

Catalytic fast co-pyrolysis of sewage sludge and sawdust was performed using Py/GC-MS for pyrolytic product upgrades. Metal oxides (NiO MoO3) ZSM-5 catalysts had been introduced into single catalytic pyrolysis. The combination NiO + MoO3 in mixed metal (MMOs) modified with under a dual-catalyst different layouts. In the pyrolysis process, specifically promoted formation phenols, ketones, furans...

Molybdenum thin films with 50 and 150 nm thicknesses were deposited on silicon substrates, using DC magnetron sputtering system, then post-annealed at different temperatures (200, 325, 450, 575 and 700°C) with flow oxygen at 200 sccm (standard Cubic centimeter per minute). The crystallographic structure of the films was obtained by means of x-ray diffraction (XRD) analysis. An atomic force micr...

Currently, and looking forward, there is an ever increasing demand to perform chemical transformations with optimized atom and energy efficiency. In parallel, there is also growing interest in diversification of chemical feedstocks from more traditional ones. For example, effective and economic transformation of biorenewable chemical feedstocks and shale-gas, are just two that can be highlighte...
