General description
Dendritic strontium is a form of strontium metal that has a unique, tree-like or branching morphology. It is often made by electrodeposition. Dendritic strontium is a silvery-white metal that is highly reactive with water and oxygen, and it readily tarnishes in air. It has several important physical properties, including a melting point of 769 °C and a density of 2.54 g/cm3.
Application
Dendritic strontium has a number of important uses including use as a component of alloys, as a material for pyrotechnic devices, as a reagent in the production of ferrite magnets, and as a dopant in the production of semiconductors.
Dendritic-strontium can be applied in the solid state synthesis of a Zintl phase, SrSn3Sb4, with an anionic channel framework of 30-membered rings.It can also be used to make strontium-potassium-niobate (Sr2KNb5O15, SKN) which is of great interest for pyroelectric sensors and various electro-optic devices.

Redox-inactive metals are found in biological and heterogeneous water oxidation catalysts, but, at present, their roles in catalysis are not well understood. Here, we report a series of high-oxidation-state tetranuclear-dioxido clusters comprising three manganese centres and a redox-inactive metal (M).

The processes of bone resorption and formation are tightly governed by a variety of systemic and local regulatory agents. In addition, minerals and trace elements affect bone formation and resorption through direct or indirect effects on bone cells or bone

Although the prevalence of aluminium-related bone diseases has declined, osteomalacia still persists at a low prevalence. The redistribution of bone disease prevalence corresponds to evolving regimens in the treatment of renal disease. Studies have demonstrated an association between the accumulation
