Description générale

Strontium is a divalent alkaline earth metal with a silvery luster. It is an active reducing agent and readily reacts with oxygen, sulfur, and halogen. It is widely used in the preparation of Sr-based optical materials for piezoelectric, electro-optic devices, and bioactive glasses for bone regeneration.

Application

Applied in the solid state synthesis of a Zintl phase, SrSn3Sb4, with an anionic channel framework of 30-membered rings.
As strontium can enhance the replication of preosteoblastic cells and stimulates bone formation, it can be used as a precursor in the preparation of bioactive glasses for bone regeneration.
Used to make Strontium-potassium-niobate (Sr2KNb5O15, SKN). SKN is of great interest for pyroelectric sensors and various electro-optic devices.2

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).

For early prevention or inhibition of postmenopausal and age-related bone loss, nutritional interventions might be a first choice. For some vitamins and minerals an important role in bone metabolism is known or suggested. Calcium and vitamin D support bone mineral

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

A number of considerations suggest that trace element disturbances might occur in dialysed patients. These must at least in part be ascribed to the dialysis treatment itself during which these constituents may either be transferred to or removed from the
