• , which was mainly due to the covalent bonding of the peptide to the surface. FTIR confirmed that the layer was DGEA as several characteristic peaks for DGEA were represented in the ND-DGEA spectrum (Figure 3). Particularly, there were peaks due to C–N stretching in primary or secondary amines of amino

Primary amines are difficult to be chemically tethered to PEG-catechol, because the typical reaction (i.e., EDC

• coupling) is the formation of an amide bond between the primary amine and the carboxyl group. Instead, we could easily generate secondary amines by using aldehyde chemistry, in other words reductive amination reaction, for the PEG-catechol to contain secondary amine groups. Secondary amines are also well

Because of this, purification and detoxification of industrial waste water has been one of the major challenges. Several methods such as adsorption, filtration, sedimentation and photocatalysis are used for the removal of

Temperature-programmed desorption (TPD) experiments have shown that chemisorbed thiolates remain stable on the ZnO surface up to approximately 500 K (227 °C) [23]. Similarly for the case of amines like THMA, adsorption leads to a Lewis acid/base interaction [24], and our TG
