Call for Papers

Global Challenges is looking for quality research papers, reviews, editorials and commentaries spanning research and practice. The journal gives priority to quality research reports that develop our understanding of, or address, the global challenges Climate Change, Energy, Food Agriculture & Nutrition, Global Health, or Water. Currently, we are particularly welcoming submissions for the following special issues:

- Interdisciplinary Research and Impact

- Optimizing the Institutional Design of Scientific Advisory Committees for Quality, Salience, and Legitimacy

Our vision is to mobilize research, debate and leadership in the global challenges and create a platform for directing and setting the research and policy agenda.

    Accumulation of Heavy Metals from Battery Waste in Topsoil, Surface Water, and Garden Grown Maize at Omilende Area, Olodo, Nigeria

    Adedotun Onoyinka Afolayan

    Version of Record online: 5 FEB 2018 | DOI: 10.1002/gch2.201700090

    The Pb, Cd, and Fe accumulation in topsoil, surface water, and in the leaf, stem, grains and roots of maize grown in a garden around Ori-Ile battery waste dumpsite, Olodo, Nigeria is determined by using AAS to measure their concentration in different samples obtained. A significant concentration of these metals was found in all samples. Thus, Ori-Ile maize is unfit for consumption by residents.

    Fluoride Removal from Aqueous Solutions Using Poly(Styrene Sulfonate)/Nanoalumina Multilayer Thin Films

    Thanjavur Chandrasekaran Prathna and Ashok M. Raichur

    Version of Record online: 16 JAN 2018 | DOI: 10.1002/gch2.201700064

    Multilayer PSS/Al2O3 thin films fabricated using a layer-by-layer (LbL) approach exhibit increased defluoridation capacity. Immobilized thin films can be reused for a number of cycles, making it cost effective. Multilayer LbL Al2O3 thin films offer advantages unlike Al2O3 nanoparticles used as a suspension.

    New Insights into the Application of Lithium-Ion Battery Materials: Selective Extraction of Lithium from Brines via a Rocking-Chair Lithium-Ion Battery System

    Lihua He, Wenhua Xu, Yunfeng Song, Yunze Luo, Xuheng Liu and Zhongwei Zhao

    Version of Record online: 15 JAN 2018 | DOI: 10.1002/gch2.201700079

    Thumbnail image of graphical abstract

    Lithium extraction from high Mg/Li ratio brine is a global technical problem. In this study, cathode material LiFePO4 is applied to extract lithium from the brine via a novel electrochemical system of LiFePO4 | NaCl solution | anion-exchange membrane | brine |FePO4. It displays a great perspective on the application in light of its high selectively, good cycling performance, effective lithium enrichment, and low cost.
