In this study, it was possible to evaluate the production of polyhydroxyalkanoates (PHAs) from microalgae Chlorella vulgaris and Tetradesmus obliquus, using 1% 0.25% (v/v) agro-indusytial Corn Steep Liquor residue, a product corn processing. The biomass subjected mechanical extraction 4% sodium hypochlorite + chloroform, extract further characterized Fourier Transform Infrared Spectroscopy (FTI...

Oxide layers on Mg97Y2Zn1 magnesium alloy with strengthening LPSO-phase were formed by plasma electrolytic oxidation (PEO) in bipolar mode frequency variation of forming current pulses (50 and 500 Hz) addition sodium aluminate or silicate to alkali phosphate fluoride electrolyte. Microstructure, chemical phase composition, corrosion mechanical properties the oxide investigated. With increasing ...

Abstract Leaching experiments were performed in calcium aluminate slag with a high-sodium carbonate adaptation of the Pedersen process. A theoretical thermodynamic study pregnant leaching solution was conducted to specify thermodynamically favored species that exist within. Using HSC 9.0 software, carbonation process simulation (neutralization CO 2 gas) simulated. Laboratory verify predictions....

Sodium Aluminate (NaAlO2) nanophosphor was prepared from analytical grade Nitrate (NaNO3) and Aluminium (Al(NO3)3.9H2O) by solution combustion method at 450° C using honey as a fuel. The sample characterised X-ray diffraction technique (XRD), UV-Visible Photoluminescence (PL). analysis carried out Bruker AXS D8 Advance diffractometer with Cu-Target (Cu/Kα radiation of wavelength λ =1.54060Å). D...

This research compared the production processes for mixed rare earth oxide (Nd/Pr oxide) powders from a leach solution obtained acid baking with nitric followed by water leaching. Furthermore, precipitation behaviour of constituent elements in liquor was examined. Development economically feasible is significant on an industrial scale. In this regard, Nd/Pr were recovered using oxalic acid, amm...

Cementing systems based on calcium aluminate cement (CAC) have been studied as an alternative cement matrix for the encapsulation of intermediate level wastes (ILW) arising from the nuclear industry. CAC-based systems have great potential for the incorporation of aluminium containing ILW owing to the near-neutral internal pH of these binders. However, CAC-based binders usually undergo phase con...

Synthesis of mesoporous materials with a bimodal pore size has always been of great importance for size-selective separation process. Especially, ordered mesoporous cubic MCM-48 with its highly interwoven and branched pore structure, is a potential separation material in applications similar to which zeolites are now being used. This material could have specific technological advantages because...
