  • Metal Salts of 4,5-Dinitro-1,3-imidazole as Colorants in Pyrotechnic Compositions
    作者:Thomas M. Klapötke、Thomas G. Müller、Magdalena Rusan、Jörg Stierstorfer

    日期:2014.6
    was synthesized by nitration of commercially available 4-nitro-imidazole. Several alkaline and alkaline earth metal salts of 4,5-dinitro-1,3-imidazole were synthesized by reaction of DNI with stoichiometric amounts of the corresponding metal hydroxides and carbonates. The synthesized salts, LiDNI·3H2O (2), NaDNI·H2O (3), KDNI·H2O (4), Ca(DNI)2·5H2O (5), Sr(DNI)2·3H2O (6), and Ba(DNI)2·4H2O (7) were

  • Pressure-Induced Polyamorphism and Formation of ‘Aragonitic’ Amorphous Calcium Carbonate
    作者:Alejandro Fernandez-Martinez、Bora Kalkan、Simon M. Clark、Glenn A. Waychunas
    DOI:10.1002/anie.201302974
    日期:2013.8.5
    Pressed for time: Amorphous calcium carbonate (ACC) undergoes a reversible amorphous–amorphous phase transition at 10 GPa, adopting an aragonite‐like local order. This result suggests a mechanism by which Mg2+—a cation with smaller ionic radius than Ca2+—modifies the local order of ACC to an aragonite‐like order by helping to decrease the molar volume of the amorphous phase.
    时间紧迫:无定形碳酸钙(ACC)在10 GPa处经历了可逆的无定形-无定形相变,并采用了类似文石的局部顺序。该结果表明一种机制,通过该机制,Mg 2+(一种离子半径小于Ca 2+的阳离子)通过帮助减少非晶相的摩尔体积,将ACC的局部顺序改变为文石状顺序。

    日期:2020.4
    modeling of calcium carbonate crystallization in a model solution of human bile is performed. CaCO3 samples are synthesized in the presence of additives with variable additive concentrations. The phase and group-structure composition of the synthesized samples is determined by X-ray powder diffraction (XRD), Fourier-transform IR spectroscopy, and optical microscopy.

    摘要在人胆汁的模型溶液中进行碳酸钙结晶的热力学和实验模型。碳酸钙3在具有可变添加剂浓度的添加剂存在下合成样品。合成样品的相和基团结构组成通过X射线粉末衍射(XRD),傅立叶变换红外光谱和光学显微镜确定。发现无定形碳酸钙和方解石主要在人胆汁模型溶液中分别存在甘氨酸,谷氨酸和白蛋白的情况下形成。当二十种氨基酸和白蛋白以人体允许的最高浓度存在时,球v石便成为主要相。样品的相和组结构组成的区别显示出取决于合成参数。
  • Monohydrocalcite and Its Relationship to Hydrated Amorphous Calcium Carbonate in Biominerals
    作者:Markus Neumann、Matthias Epple
    DOI:10.1002/ejic.200601033
    日期:2007.5
    Calcium carbonate monohydrate (monohydrocalcite) is prepared and structurally characterised by X-ray diffraction, X-ray absorption spectroscopy (EXAFS), thermal analysis, IR spectroscopy, and scanning electron microscopy. It is compared to hydrated phases of amorphous calcium carbonate (ACC) that have frequently been observed in biomineralisation. The crystal water is more strongly bound than in hydrated
    碳酸钙一水合物(单氢方解石)的制备和结构表征通过 X 射线衍射、X 射线吸收光谱 (EXAFS)、热分析、红外光谱和扫描电子显微镜。将其与生物矿化中经常观察到的无定形碳酸钙 (ACC) 的水合相进行比较。结晶水比水合 ACC 相的结合力更强,可以通过其红外光谱将单水方解石与 ACC 区分开来。EXAFS 结果表明,一水方解石是一些生物和合成 ACC 相的合适模型,尽管不是所有这些相。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
  • Thermal behaviors of amorphous calcium carbonates prepared in aqueous and ethanol media
    作者:N. Koga、Y. Yamane
    DOI:10.1007/s10973-008-9110-3
    日期:2008.11
    Two different samples of amorphous calcium carbonate (ACC) hydrates were prepared respectively by mixing aqueous solutions of CaCl2 and Na2CO3-NaOH and by allowing the diffusion of (NH4)2CO3 sublimate into ethanol solution of CaCl2. Thermal behaviors of the synthetic ACCs were investigated comparatively by means of thermoanalytical techniques complimented by powder X-ray diffraction, FTIR spectrometry and microscopic observations. The anhydrous ACCs produced by the thermal dehydration of the respective samples were crystallized to calcite in different ways. The sample prepared in aqueous medium was crystallized at around 600 K in a single step. Crystallization in two separated steps at around 600 and 825 K was observed for the sample prepared in ethanol medium. Characteristics of the crystallization processes were discussed from thermodynamic and kinetic points of view.
    通过将 CaCl2 和 Na2CO3-NaOH 的水溶液混合,以及让 (NH4)2CO3 升华扩散到 CaCl2 的乙醇溶液中,分别制备了两种不同的无定形碳酸钙(ACC)水合物样品。通过热分析技术以及粉末 X 射线衍射、傅里叶变换红外光谱和显微镜观察,对合成 ACC 的热行为进行了比较研究。通过热脱水法制备的无水 ACC 样品以不同方式结晶成方解石。在水介质中制备的样品在 600 K 左右的温度下一次性结晶。在乙醇介质中制备的样品在 600 K 和 825 K 左右分两步结晶。从热力学和动力学角度讨论了结晶过程的特征。
