However, the only reactivity has previously been observed for the copper II -hydroperoxo complexes is electrophilic, occurring through O-O bond cleavage. Here we report that a mononuclear end-on copper II -hydroperoxo complex, which has been successfully characterized by various physicochemical methods including UV-vis, rRaman, CSI-MS and EPR, is a reactive oxidant that utilizes a nucleophilic mechanism. In addition, DFT calculations fully support the electronic structure of this complex as a copper II -hydroperoxo complex with trigonal bipyramidal coordination geometry. The copper II -hydroperoxo complex is an especially reactive oxidant in aldehyde deformylation with 2-PPA and CCA relative to the other metal-bound reactive oxygen species reported so far. The observation of nucleophilic reactivity for a copper II -hydroperoxo species expands the known chemistry of metal-reactive oxygen species.

Ni-Co hydroxide nanosheets constructed hollow cubes were successfully synthesized by using Cu2O cubes as templates and subsequently etched by Na2S2O3 to achieve a hollow cubic structure. It was observed by transmission electron microscopy TEM that the increasing Ni precursor resulted in particle morphology, and the increasing ratio of the Co precursor resulted in more lamellar morphology. The sample with the composition of Ni0. Similar strategies could be applied for the design of other electrode materials with high efficiency for nonenzymatic glucose determination.

When I tried to twist away, he returned to my breasts. Over and over again, we played that game. And the longer it went on, the wetter I became. "Does this guy," Chris asked, his voice husky as he ran a single finger up and down the soft hollow of skin just behind my ear along the back of my jaw, "know right where to touch you to drive you wild?" I wanted him to both continue and yet stop touching me there.
