TL;DR: In this paper, the structure of a compound of magnesium oxomethoxoniobate, Mg2Nb2O2(OMe)10(MeOH)4 (1), resulting from partial decomposition of bimetallic alkoxionates has been isolated from solutions obtained by interaction of magnesium and niobium methoxides in MeOH.

TL;DR: In this paper, the preparation of metal alkoxide solutions-precursors for powders and thin films of the superconductor YBa2Cu3O7-x is discussed.
Abstract: Preparation of the metal alkoxide solutions-precursors for powders and thin films of the supercon ductor YBa2Cu3O7-x is discussed. Films, powders and ceramics of the superconductor YBa2Cu3O7-x have been obtained. Oriented and polycrystalline films with the thickness of 0.1-0.15μm and different morphology have been studied. Resistivity of the films turned to zero at 70-77K.

TL;DR: The thermal stability of the synthesized alcoholates and their solubility were studied and a method described in the literature, based on an exchange reaction of the halides with alkali alcoholates, does not lead to the formation of individual alcoholates.
Abstract: 1. Possible methods of synthesizing zinc, cadmium, and mercury methylates and ethylates were discussed. 2. The most convenient method for the production of Zn, Cd, and Hg methylates, as well as Cd and Hg ethylates is exchange interaction of the acetates with alkali alcoholates in alcohol solutions. Cd(OEt)2 can also be produced from the methylate by exchange with EtOH. 3. A method described in the literature, based on an exchange reaction of the halides with alkali alcoholates, does not lead to the formation of individual alcoholates. 4. The thermal stability of the synthesized alcoholates and their solubility were studied.

TL;DR: In this article, a unified overview of matrix nanocomposites is presented underlining the need for these materials, their processing methods and some recent results on structure, properties and potential applications, perspectives including need for such materials in future space mission and other interesting applications together with market and safety aspects.
Abstract: Nanocomposites, a high performance material exhibit unusual property combinations and unique design possibilities. With an estimated annual growth rate of about 25% and fastest demand to be in engineering plastics and elastomers, their potential is so striking that they are useful in several areas ranging from packaging to biomedical applications. In this unified overview the three types of matrix nanocomposites are presented underlining the need for these materials, their processing methods and some recent results on structure, properties and potential applications, perspectives including need for such materials in future space mission and other interesting applications together with market and safety aspects. Possible uses of natural materials such as clay based minerals, chrysotile and lignocellulosic fibers are highlighted. Being environmentally friendly, applications of nanocomposites offer new technology and business opportunities for several sectors of the aerospace, automotive, electronics and biotechnology industries.

TL;DR: The complex and metastable behavior of nonstoichiometric iron oxide (wüstite) at the nanoscale was studied by a combination of Mossbauer spectroscopy and magnetic characterization.
Abstract: We have investigated the structural, magnetic, and electronic properties of nonstoichiometric iron oxide nanocrystals prepared by decomposition of iron(II) and iron(0) precursors in the presence of organic solvents and capping groups. The highly uniform, crystalline, and monodisperse nanocrystals that were produced enabled a full structural and compositional survey by electron microscopy and X-ray diffraction. The complex and metastable behavior of nonstoichiometric iron oxide (wustite) at the nanoscale was studied by a combination of Mossbauer spectroscopy and magnetic characterization. Deposition from hydrocarbon solvents with subsequent self-assembly of iron oxide nanocrystals into superlattices allowed the preparation of continuous thin films suitable for electronic transport measurements.

TL;DR: Ferroelectrics are dielectric materials that have spontaneous polarization in certain temperature range and show nonlinear polarization-electric field dependence called a hysteresis loop as discussed by the authors.
Abstract: There has been a resurgence of complex oxides of late owing to their ferroelectric and ferromagnetic properties. Although these properties had been recognized decades ago, the renewed interest stems from modern deposition techniques that can produce high quality materials and attractive proposed device concepts. In addition to their use on their own, the interest is building on the use of these materials in a stack also. Ferroelectrics are dielectric materials that have spontaneous polarization in certain temperature range and show nonlinear polarization–electric field dependence called a hysteresis loop. The outstanding properties of the ferroelectrics are due to non-centro-symmetric crystal structure resulting from slight distortion of the cubic perovskite structure. The ferroelectric materials are ferroelastic also in that a change in shape results in a change in the electric polarization (thus electric field) developed in the crystal and vice versa. Therefore they can be used to transform acoustic wav...
