Adsorption of Crystal Violet Dye from Aqueous Solution on Palm Kernel Shell Activated Carbon – Magnesium Oxide Composites Particles

Adebayo G.B., Adegoke H.l, Adekola F.A., Omolade O.O, Abiodun A., University of Ilorin, NG

A composite of activated carbon prepared from palm kernel shells (PKSAC) and magnesium oxide (MgO) particles was synthesis through hydrothermal method in ratio 10:1. The Palm kernel was carbonized at 6000C for two hours, it [...]

Novel electrospun PVA/Fe-MOF nanofibres as a super adsorbing material of lead ions in aqueous solution

Shooto N.D., Dikio E.D., Sikhwivhilu L., Wankasi D., VUT, ZA

In this study electrospun PVA nanofibres were functionalized with Fe-MOFs to synthesise a novel super adsorbing material. The synthesized material was characterized by scanning electron microscope (SEM), Fourier transform infrared (FTIR) and Thermogravimetric analysis (TGA). [...]

Thermochemical Copper Oxide – Copper Sulfate Water Splitting Cycle for Solar Hydrogen Production

Bhosale R., Dardor D., Kumar A., AlMomani F., Ghosh U., Qatar University, QA

H2 is considered as one of the potential energy carriers due to its capacity of producing 143 MJ/kg of energy (higher in comparison with the oil, gas, and coal individually) and its environmentally friendly nature [...]

Preparation of GO/PVA composite as an adsorbent for the removal of Cr(VI) from water

Singh D.K., Kumar V., Hasan S.H., Indian Institute of Technology (BHU), IN

Cr(VI) is a known toxic heavy metal and has been considered as a priority pollutant in water [1]. The effluent of various industries including electroplating, anodizing baths, leather tanning, steel industry and chromium based catalyst [...]

Adsorption of Cd (II) Ions from Aqueous Solution Using Activated Carbon Prepared from Vitellaria paradoxa Shell

Adebayo G.B., Adekola F.A., Jimoh A.A., Alao F.O., Adegoke H.I., University of Ilorin, NG

Activated carbon prepared from vitellaria paradoxa shell using ortho-phosphoric acid as activating agent was used for the removal of Cd (II) ions from aqueous solution. The adsorbent sample was characterized by some physicochemical and spectroscopic [...]

Batch Sorption of Ciprofloxacin on Kaolinitic Clay and nHematite Composite: Equilibrium and Thermodynamics Studies

Adekola F.A., Adegoke H.I., Abdulsalam I.O., University of Ilorin, NG

Ciprofloxacin is a second generation fluoroquinolone antibiotic of high use. It has a high aqueous solubility and a long environmental half-life. In this study nanoparticles of hematite and hematite-kaolin composite were prepared and characterized using [...]

Computational Modeling with a New Lattice-Based Continuum Formulation for the Coupled Thermodynamic and Mechanical Equilibrium of Polycrystalline Solids

Bassman L., Garikipati K., Deal M., Stanford University, US

A new formulation and computational framework is presented for modeling coupled self-diffusion and mechanics in polycrystalline materials. The continuum formulation includes constitutive models derived from lattice-level thermodynamic and mechanical considerations. From a complete statement of [...]
