The potential of metallic copper as an intrinsically antibacterial material is gaining increasing attention in the face of the growing antibiotic resistance of bacteria. However, the mechanism of the so-called "contact killing" of bacteria by copper surfaces is poorly understood and requires further investigation. In particular, the influences of bacteria–metal interaction, media composition, and copper surface chemistry on contact killing are not fully understood. In this study, copper oxide fo Copper oxides are unusual in two respects. First, octahedral-site Cu(II):t6e3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and, therefore, a strong Jahn–Teller ion; consequently, Cu(II) ions normally occupy octahedral sites that are deformed to tetragonal (c/a > 1) symmetry by Jahn–Teller orbital ordering. However, without cooperativity stabilizing long-range orbital ordering, the electrons may couple locally to E-mode vibrations, forming vibronic states in a dyn Copper oxides are unusual in two respects. First, octahedral-site CuII:t6e3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and, therefore, a strong Jahn–Teller ion; consequently, CuII ions normally occupy square coplanar, pyramidal, or octahedral sites that are deformed to tetragonal (c/a > 1) symmetry by Jahn–Teller orbital ordering. However, without a cooperativity stabilizing long-range orbital ordering, the electrons may couple locally to E-mode vibrations, for What is Copper oxide?Copper oxide (CuO) is a semiconducting compound with a monoclinic structure. CuO has attracted particular attention because it is the simplest member of the family of copper compounds. It exhibits various potentially useful physical properties, such as high-temperature superconductivity, electron correlation effects, and spin dynamics. Copper oxide is relatively cheap, easily mixed with polarized liquids (i.e., water) and polymers, and relatively stable in terms of both chem
