In this paper, double imaging by a periodic bi-fold transformation medium is presented. It is shown that a periodic array of axisymmetric isovolumetric coordinate transformation metamaterials has a ...

Nickel-catalyzed C–O bond cleavage provides an important strategy to construct C–C bonds from oxygenated electrophiles. The present study elucidated the mechanisms of ethers (R1OR1) deoxygenation via ...
