Rhodonite is a manganese inosilicate, with the formula (Mn, Fe, Mg, Ca)SiO 3, and member of the pyroxenoid group of minerals, crystallizing in the triclinic system. It commonly occurs as cleavable to compact masses with a rose-red color (its name comes from Ancient Greek ῥόδον (rhódon) 'rose'), often tending to brown due to surface oxidation.
The name is derived from the Greek "rhodon" for "rose-like", in common with other pink mineral types (such as rhodochrosite, rhodonite). This coloration, and the commonly inclusion-free nature of garnet from this locality, has led to rhodolite being used as a gemstone. Rhodolite like other varietal names is not officially recognized as a ...
Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO 3.In its pure form (rare), it is typically a rose-red colour, [5] but it can also be shades of pink to pale brown.
[citation needed] It covers hundreds of minerals, with details of their structure, chemistry, optical and physical properties, distinguishing features, and paragenesis. Entries range from one or two pages for obscure minerals, to dozens of pages for important ones like feldspars. The first edition was published in 1966, and a substantially ...
With physical trauma or disease suffered by an organism, healing involves the repairing of damaged tissue(s), organs and the biological system as a whole and resumption of (normal) functioning. Medicine includes the process by which the cells in the body regenerate and repair to reduce the size of a damaged or necrotic area and replace it with ...
The plant has been used for centuries in the South Pacific to make a ceremonial drink with sedative and anesthetic properties, with potential for causing liver injury. [117] Piscidia erythrina / Piscidia piscipula: Jamaica dogwood: The plant is used in traditional medicine for the treatment of insomnia and anxiety, despite serious safety ...
Crystal healing is a pseudoscientific alternative-medicine practice that uses semiprecious stones and crystals such as quartz, agate, amethyst or opal. Despite the common use of the term "crystal", many popular stones used in crystal healing, such as obsidian, are not technically crystals .
The majority of the approaches that are described in literature regarding self-healing materials can be applied to make “self-healing” coatings, including microencapsulation [87] [59] and the introduction of reversible physical bonds such as hydrogen bonding, [88] ionomers [89] [90] and chemical bonds (Diels-Alder chemistry).
