  2. Zinc selenide - Wikipedia

    en.wikipedia.org/wiki/Zinc_selenide

    Zinc selenide is the inorganic compound with the formula ZnSe. It is a lemon-yellow solid although most samples have a duller color due to the effects of oxidation. It is an intrinsic semiconductor with a band gap of about 2.70 eV at 25 °C (77 °F), equivalent to a wavelength of 459 nm.

    en.wikipedia.org/wiki/Selenium_compounds

    The selenide dianion Se 2− forms a variety of compounds, including the minerals from which selenium is obtained commercially. Illustrative selenides include mercury selenide (HgSe), lead selenide (PbSe), zinc selenide (ZnSe), and copper indium gallium diselenide (Cu(Ga,In)Se 2). These materials are semiconductors.

    en.wikipedia.org/wiki/Selenium

    The chronic toxic dose of selenite for humans is about 2400 to 3000 micrograms of selenium per day. [140] Hydrogen selenide is an extremely toxic, corrosive gas. [ 141 ] Selenium also occurs in organic compounds, such as dimethyl selenide, selenomethionine , selenocysteine and methylselenocysteine , all of which have high bioavailability and ...

  5. Selenium disulfide - Wikipedia

    en.wikipedia.org/wiki/Selenium_disulfide

    Selenium disulfide, also known as selenium sulfide, is a chemical compound and medication used to treat seborrheic dermatitis, dandruff, and pityriasis versicolor. [1] [2] It is applied to the affected area as a lotion or shampoo. [3]

  6. Selenide - Wikipedia

    en.wikipedia.org/wiki/Selenide

    Sample of cadmium selenide, a pigment. The parent inorganic selenide is hydrogen selenide (H 2 Se). It is a colorless, malodorous, toxic gas. It dissolves in aqueous solution, to give the hydrogenselenide or biselenide ion HSe −. At higher pH, selenide forms. Solutions of hydrogen selenide and selenide are oxidized by air to give elemental ...

  7. Zinc pyrithione - Wikipedia

    en.wikipedia.org/wiki/Zinc_pyrithione

    Zinc pyrithione (or pyrithione zinc) is a coordination complex of zinc. It has fungistatic (inhibiting the division of fungal cells) and bacteriostatic (inhibiting bacterial cell division) properties and is used in the treatment of seborrhoeic dermatitis [ 2 ] and dandruff .

  8. Zinc toxicity - Wikipedia

    en.wikipedia.org/wiki/Zinc_toxicity

    Zinc toxicity is a medical condition involving an overdose on, or toxic overexposure to, zinc. Such toxicity levels have been seen to occur at ingestion of greater than 50 mg of zinc. [1] [unreliable medical source?] Excessive absorption of zinc can suppress copper and iron absorption. The free zinc ion in solution is highly toxic to bacteria ...

    en.wikipedia.org/wiki/Talk:Zinc_selenide

    ZnSe has a reasonably large Verdet constant (roughly 1 min. cm-1 G-1 at = nm) and was suggested for use in optical isolators, see Wunderlich J. A. and DeShazer L. G., Applied Optics 16 (6), 1584 (1977). Note that although the rare-earth orthoferrites have much higher Verdet constants, they are birefringent and aren't much good at producing ...
