Capture of Water Contaminants by a New Generation of Sorbents Based on Graphene and Related Materials

Perspectives regarding metal/mineral-incorporating materials for water purification: with special focus on Cr(vi) removal

“…A highly selective Fe 3 O 4 @Arg-PPy adsorbent was effectively synthesized by a one-pot chemical polymerization of pyrrole with arginine and was made commercially available as Fe 3 O 4 NPs. The FTIR, VSM, XRD, and TEM analyses of the Fe 3 O 4 @ Arg-PPy nanocomposite imply the successful implementation of arginine and Fe 3 O 4 into PPy.…”

“…2 Pollution of water occasioned by different toxic contaminants, mostly including heavy metals, organics, and oil, has steadfastly become one of the most impactful environmental challenges globally. 3 Water is usually taken for granted when produce safety is taken into consideration. Not only it is vital for crop growth but also in their processing as well.…”

Economic Growth and Judicial Independence, a Dozen Years on: Cross-Country Evidence Using an Updated Set of Indicators

“…It is conjectured that this is because central bankers, who are not subject to re-election pressure, are better able to carry out promises of tight monetary supply and can thus make more credible commitments than can politicians seeking re-election. Various approaches toward measuring CBI have been proposed (e.g., Cukierman 1992;Cukierman et al 1992;Debelle and Fisher 1995;Grilli et al 1991). This work finds that de jure CBI is a good predictor of monetary stability in OECD countries only, and that the turnover rate of central bank governors (a de facto proxy) is a much better predictor for less developed countries (for sur-1 Although it is, at times, interpreted rather oddly, as in Rios-Figuero and Staton (2012), who equate de jure JI with the incentives to behave and de facto with actual behavior.…”

New modified chitosan composites and nanocomposites for different applications

“…organics, and oil, which become one of the world ' s most impactful environmental challenges [1]. Most heavy metal ions are highly toxic, non-degradable and have a tendency to bioaccumulate and cause dangerous impact to human health [2][3][4].…”
