  2. Copper in biology - Wikipedia

    en.wikipedia.org/wiki/Copper_in_biology

    Copper is an essential trace element that is vital to the health of all living things (plants, animals and microorganisms). In humans, copper is essential to the proper functioning of organs and metabolic processes. Also, in humans, copper helps maintain the nervous system, immune system, brain development, and activates genes, as well as ...

  3. Copper - Wikipedia

    en.wikipedia.org/wiki/Copper

    Copper. face-centered cubic (fcc) (cF4) Copper is a chemical element; it has symbol Cu (from Latin cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity ...

  4. Biometal (biology) - Wikipedia

    en.wikipedia.org/wiki/Biometal_(biology)

    Biometal (biology) Element percentages in the human body. Biometals (also called biocompatible metals, bioactive metals, metallic biomaterials) are metals normally present, in small but important and measurable amounts, in biology, biochemistry, and medicine. The metals copper, zinc, iron, and manganese are examples of metals that are essential ...

  5. List of copper alloys - Wikipedia

    en.wikipedia.org/wiki/List_of_copper_alloys

    Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion . Of the large number of different types, the best known traditional types are bronze , where tin is a significant addition, and brass , using zinc instead.

  6. Antimicrobial properties of copper - Wikipedia

    en.wikipedia.org/wiki/Antimicrobial_properties...

    Copper alloy surfaces have intrinsic properties to destroy a wide range of microorganisms.In the interest of protecting public health, especially in healthcare environments with their susceptible patient populations, an abundance of peer-reviewed antimicrobial efficacy studies have been conducted in the past ten years regarding copper's efficacy to destroy E. coli O157:H7, methicillin ...

  7. Oligodynamic effect - Wikipedia

    en.wikipedia.org/wiki/Oligodynamic_effect

    Oligodynamic effect. The oligodynamic effect (from Greek oligos, "few", and dynamis, "force") is a biocidal effect of metals, especially heavy metals, that occurs even in low concentrations. This effect is attributed to the antibacterial behavior of metal ions, which are absorbed by bacteria upon contact and damage their cell membranes.

  8. Metal–organic framework - Wikipedia

    en.wikipedia.org/wiki/Metal–organic_framework

    MIL-101, a large-cavity MOF having the formula [Cr 3 F(H 2 O) 2 O(BDC) 3], is a cyanosilylation catalyst. [56] The coordinated water molecules in MIL-101 are easily removed to expose Cr(III) sites. As one might expect, given the greater Lewis acidity of Cr(III) vs. Cu(II), MIL-101 is much more active than HKUST-1 as a catalyst for the ...

  9. Copper compounds - Wikipedia

    en.wikipedia.org/wiki/Copper_compounds

    As with other elements, the simplest compounds of copper are binary compounds, i.e. those containing only two elements, the principal examples being oxides, sulfides, and halides. Both cuprous and cupric oxides are known. Among the numerous copper sulfides, important examples include copper (I) sulfide and copper (II) sulfide. [citation needed]
