说明

General description

钙是一种高度反应性、无毒金属，常通过铝热法或电解法制备。纯度99%的钙金属颗粒是多种工业和学术应用中的宝贵材料。该颗粒由高纯度钙制成，并在严格的制造标准下生产以确保纯度和质量。颗粒形式比粉末更容易处理和储存，令其可以在各种应用中方便地使用。

Application

Ca₈Al₃ 和 Ca₁₃Al₁₄ 的前体；具有新金属性 Zintl 相的金属互化物。⁷

我们的99%纯度钙金属颗粒被广泛用作制备各种金属（包括铀和钍）的还原剂。它们也是生产铝合金的必备成分，铝合金常用于航空和汽车行业。这些钙金属颗粒也用于钢的脱硫，并可作为各种金属生成的脱氧剂。此外，我们的钙金属颗粒在有机合成中得到广泛应用，用于将醛、酮、酯和酸酐等基团还原为相应的醇。该金属也用于制备有机合成中的关键中间体格式试剂。

Features and Benefits

质量有保障 - 以高纯度原料制成并在严格制造标准下生产以确保一致的性能。
更容易处理和储存 - 与粉末相比，颗粒形式确保材料在储存和处理过程中有更高的稳定性。

Chemical Synthesis of Monodisperse Magnetic Nanoparticles

Magnetic nanoparticles have attracted tremendous attention due to their novel properties and their potential applications in magnetic recording, magnetic energy storage and biomedicine.

N-terminal modifications improve the receptor affinity and pharmacokinetics of radiolabeled peptidic gastrin-releasing peptide receptor antagonists: examples of 68Ga- and 64Cu-labeled peptides for PET imaging.

Eleni Gourni et al.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 55(10), 1719-1725 (2014-08-26)

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

Trimeric intracellular cation channels and sarcoplasmic/endoplasmic reticulum calcium homeostasis.

Circulation research, 114(4), 706-716 (2014-02-15)

Trimeric intracellular cation channels (TRIC) represents a novel class of trimeric intracellular cation channels. Two TRIC isoforms have been identified in both the human and the mouse genomes: TRIC-A, a subtype predominantly expressed in the sarcoplasmic reticulum (SR) of muscle

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
