An interconnected graphene network (IGN) structure with excellent photoluminescence (PL) properties was synthesized using a one-pot microwave-assisted hydrothermal carbonization route. The material exhibited intense and excitation-wavelength dependent PL emission located mainly in the UV-blue light range (300-450 nm). The result

Phosphorylated peptides are attractive targets in the study of the phosphoproteome. Here, we introduce a simple and convenient micropipette-tip method for the separation of phosphorylated and nonphosphorylated peptides by using a phosphate-binding zinc(II) complex of 1,3-bis(pyridin-2-ylmethylamino)propan-2-olate (Phos-tag). A 200-μL micropipette
