Abstract
This article deals with the adsorption performances of the unmodified nanodiamond (ND) and thermally oxidized nanodiamond (Ox-ND) for the removal of different heavy metal ions such as Fe (III), Cu (II), Cr (VI), and Cd (II) from wastewater. The adsorption capacities of the ions onto adsorbents are higher and follow the order: Ox-ND-3 > Ox-ND-1.5 > ND, which is consistent with their surface areas, zeta potentials, and the presence of carboxyl groups, suggesting that electrostatic attractions between the positive metal ions and the negatively charged adsorbents are the predominant adsorption mechanisms. Adsorption capacities of these adsorbents were found to be 26.8, 31.3, and 45.7 mg/g for Fe...

Abstract
Leaving an imprint: Hierarchical protein imprinting starting from wide-pore silica modified with a submonolayer of adsorbed protein (IgG or HSA) leads to an inverse polymeric replica of the silica template that features highly accessible protein-complementary binding sites (see picture). The resulting poly(acrylamide) beads (PIgG or PHSA) feature high binding capacities and can be used to selectively capture the proteins HSA and IgG from blood serum
