    LiNbO3-type MnMO3 (M = Ti, Sn) were synthesized under high pressure and temperature; their structures and magnetic, dielectric, and thermal properties were investigated; and their relationships were discussed. Optical second harmonic generation and synchrotron powder X-ray diffraction measurements revealed that both of the compounds possess a polar LiNbO3-type structure at room temperature.

    In the method of the present invention for producing fatty acid alkyl ester and/or glycerin, as a heat source for an alcohol refining step of refining alcohol from unreacted alcohol that remains without reacting in a first reaction step, at least a part of heat of the unreacted alcohol is used. This allows reducing costs in production of fatty acid alkyl ester and/or glycerin over a solid catalyst.

    attention for lithium-ion batteries due to safety as anode upon fast and low temperature cycling as well as appropriate stability during insertion and extraction of guest ions. However, TiO2 has low conductivity and sluggish diffusion of Li+. In order to eliminate these shortcomings, reducing of particle size and doping are considered as promising approaches. Herein, we investigate the effect of doping
    由于快速和低温循环时作为阳极的安全性以及在客体离子的插入和提取过程中的适当稳定性,二氧化钛已受到离子电池的广泛关注。但是,TiO 2的电导率低,Li +的扩散缓慢。为了消除这些缺点,减小粒径和掺杂被认为是有前途的方法。在本文中,我们研究了掺杂(Mn / Ti的原子比= 0.05; 0.1; 0.2)对具有纳米微粒形态的锐钛矿二氧化钛特性的影响。如发现的那样,就二氧化钛的电池性能而言,Mn / Ti = 0.05是最佳掺杂剂浓度:在1 C进行118次循环后,仍保持113 mAh g -1的容量与未掺杂的锐钛矿相比,这要高得多。由于Mn 3+的引入和电导率的提高,这种改善的电化学行为与锐钛矿晶格膨胀有关。

    The ATiO3 (A=Co, Mn, Ni) dielectric ceramics have been synthesized by the conventional solid‐state ceramic route. The structure and microstructure of these ceramic samples have been studied using powder X‐ray diffraction and scanning electron microscopy. The microwave dielectric properties such as relative permittivity (ɛr), quality factor (Qu×f), and coefficient of temperature variation of resonant frequency (τf) of the ceramics have been measured in the frequency range 4–6 GHz using resonance methods. The dielectric constant of ATiO3 (A=Co, Mn, Ni) varies from 19 to 25 and τf close to −50 ppm/°C. The ceramics have high‐quality factors (Qu×f) of 62 500 GHz (at 5.42 GHz) for CoTiO3, 15 200 GHz (at 5.22 GHz) for MnTiO3, and 13 900 GHz (at 5.24 GHz) for NiTiO3, respectively.

    Abstract A high pressure phase of MnTiO3 II is newly synthesized at high pressures and temperatures. An equilibrium phase boundary between an atmospheric pressure phase of MnTiO3 I and MnTiO3 II is P(kb) = 110 − 0.044 T(°C). X-ray analysis of powder specimens has revealed that the high pressure phase MnTiO3 II has the disordered ilmenite structure with the hexagonal lattice parameters of a = 5.2051
    摘要 MnTiO3 II 高压相是在高压和高温下新合成的。MnTiO3 I 和 MnTiO3 II 的大气压相之间的平衡相界是 P(kb) = 110 - 0.044 T(°C)。粉末样品的 X 射线分析表明,高压相 MnTiO3 II 具有无序矿结构,六方晶格参数为 a = 5.2051 A、c = 13.699 A、ca = 2.632 和 V = 321.4 A[3]。从 MnTiO3 1 到 MnTiO3 II 的转变导致 a 轴膨胀 1.3%,c 轴收缩 4.1%,导致体积减少 1.6%。穆斯堡尔效应和顺磁性 ESR 测量表明,MnTiO3 II 在低于 24°±1°K 时是反磁性的。
