General description
Calcium is a highlyreactive and non-toxic metal that is widely used as a reducing agent. It isalso used for the improvement of steel, as a desulfurizer, and as an alloying agent. Calciumis prepared by the aluminothermal or electrolysis method.
Application
Ca8Al3 和 Ca13Al14 的前体；具有新金属性 Zintl 相的金属互化物。7
Calcium can be used as:
- Process control agent in mechanical alloying of titanium to get maximum powder yield and microstructural stability.
- A precursor to synthesize Ca8Al3 and Ca13Al14 with metallic Zintl phases and Ca6.2Mg3.8Sn with an unprecedented type of tin chain composed of square-planar tin units.
- A catalyst in the highly selective oxidation of phenols.
Features and Benefits
•Distillation-purification of calcium removes impurities like oxides, nitrides, and residual salts, enabling cleaner and more efficient metallurgical reductions for improved alloy quality.

Gastrin-releasing peptide receptors (GRPrs) are overexpressed on a variety of human cancers, providing the opportunity for peptide receptor targeting via radiolabeled bombesin-based peptides. As part of our ongoing investigations into the development of improved GRPr antagonists, this study aimed at

A classic feature of apoptotic cells is the cell-surface exposure of phosphatidylserine (PtdSer) as an "eat me" signal for engulfment. We show that the Xk-family protein Xkr8 mediates PtdSer exposure in response to apoptotic stimuli. Mouse Xkr8(-/-) cells or human

Fluorescent calcium sensors are widely used to image neural activity. Using structure-based mutagenesis and neuron-based screening, we developed a family of ultrasensitive protein calcium sensors (GCaMP6) that outperformed other sensors in cultured neurons and in zebrafish, flies and mice in
