In this study, four different weight% of Punica granatum fruit peel extract were used as green stabilizers to synthesize IONPs followed by a series of characterization experiments and in vitro anticancer evaluation. Results revealed that all synthesized IONPs have high degree of crystallinity and purity. The optimum saturation magnetization, and hydrodynamic size were found to be ∼69 emu.g−1, and 26.52 nm, respectively. Morphological studies demonstrated that adding peel extract decreased size of NPs with the average particle size below 11 nm. Cytotoxicity assay showed that the IONPs were not react...

Gibril, Fangong KongAbstractApplication of the lignin-based monomer in polymers synthesis will reducing the use of petrochemical-based monomers, enhance the polymer/copolymers properties, and disposing lignin in a profitable way. Accordingly, in this work, the lignin-vinyl acetate monomer (LVAc) and its copolymers were synthesized successfully. To obtain the LVAc, firstly, lignin was activated with the amine using diethylenetriamine (DETA) and then followed by the grafting with chlorovinyl aceta...

In this study four kinds of fingerprints, including sweat, inkpad, sunscreen, and liquid foundation, were analyzed by air-flow assisted desorption electrospray ionization mass spectrometry imaging (AFADESI-MSI). AFADESI was employed with air flow of 45 L min−1, and 5 μL min−1 acetonitrile was used as spray solvent at spray voltage of 7000 V. Positive ion full scan mode (100−1000 Da) was chosen. The results showed that AFADESI-MSI method could not only obtain chemical information of various endogenous and exogenous substances in fingerprints, but also obtain high resolution images of fingerprints. In ad...

To further improve the CO2 adsorption performance of MOFs, a compound material of l-arginine modified graphene oxide (GO) with MOFs (MOF/GO-Arg) was synthesized. Introduction of amino acid-functionalized lamellar GO into MOF material not only generated new pores at their interface to improve the adsorption of the MOF but also promoted the CO2 capture at low humidity. The structural and chemi...

Herein, a core@shell structural Fe-Fe2O3@poly (hexachlorocyclotriphosphazene-co-polyethylenimine) (Fe-Fe2O3@PHCP) magnetic nanochain with high saturation magnetization was fabricated and used for effective adsorption and reduction of hexavalent chromium. The morphology and microstructure of Fe-Fe2O3@PHCP were c...

This study evaluated the performance of such a ZLD method for immobilizing heavy metals (Se, As, Cd and Cr) and chloride in FGD wastewater and/or CCRs. Effects of different coal fly ash (bituminous (BCFA) and sub-bituminous (SCFA)), activating agent (Portland cement (PC) and lime) and pretreatment of brines by zero valent iron (ZVI) on the S/S process were evaluated. Short-term and long-term leaching tests were conducted to evaluate performance of the S/S solids in pollutant retainment. The pre-treatment of FGD brine by ZVI enhanced the retainment of heavy metals when BCFA was used, but not when SCFA was used since it alre...

In this study, cyclic voltammetry, scanning electronic microscopy, and electrochemical impedance spectroscopy were used to select better anode electrode configurations (iron wire, iron gauze, and iron coil). The results indicate that iron coil had the least degree of passivation. Different imposed current waveforms during the electrochemical generation of Fe(VI) were also investigated, and the iron coil imposed with square alternating current (AC) wave can mitigate the anode passivation, resulting in higher Fe(VI) production efficiency. The optimum conditions for the electrochemical generation of Fe(VI) were evaluated and ...

HAP supported cobalt-based catalyst (Co-HAP) was synthesized via a facile ion exchange-calcination method to reduce the Co leaching. The synthesized Co-HAP was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electron microscope (TEM), Brunauer-Emmett-Teller (BET) analysis and X-ray photoelectron spectros...

Nguyen, Gordon Southam, Ting-Shan Chan, Ying-Rui Lu, Longbin HuangAbstractHardpan caps formed after extensive weathering of the top layer of sulfidic tailings have been advocated to serve as physical barriers separating reactive tailings in depth and root zones above. However, in a hardpan-based root zone reconstructed with the soil cover, roots growing into contact with hardpan surfaces may induce the transformation of Fe-rich minerals and release potentially toxic element...
