A sol-gel synthesis and gas-sensing properties of finely dispersed ZrTiO4

Microplotter-Printed On-Chip Combinatorial Library of Ink-Derived Multiple Metal Oxides as an “Electronic Olfaction” Unit

“…To deposit metal oxides, the most appropriate precursors are inks prepared in the frames of sol–gel synthesis, a type of liquid-phase synthesis, that allows one to design a product whose properties are adjusted by precursor’s concentration in the printed gel, other additives, types of solvent, transition kinetics, and aging . Recently, we have developed true solutions of hydrolytically active precursors based on heteroligand complexes of metal alkoxo-β-diketonates to be utilized as functional inks, in which the composition of the coordination sphere is varied in a controlled manner to finely tune the characteristics of thin-film metal oxide nanostructures under printing . The type of functional inks used in this study allows one to vary the chemical composition of the obtained thin-film nanomaterials in a wide range. , Thus, these inks can be easily modified by adding organometallic compounds of catalytic metals to their composition, which will then participate in the processes of hydrolysis and polycondensation of precursors with the subsequent formation of catalytically active compounds introduced in the obtained planar nanostructures.…”

Application of Rock Weathering and Colonization by Biota for the Relative Dating of Moraines from the Arid Part of the Russian Altai Mountains

“…The absence of a deviation of the dΣ(q)/dΩ curve from the power law (the onset of the Guinier regime) at small values of q means that the upper self-similarity limit ξ of the surface fractal is larger than the maximum size R max of the inhomogeneities (pores) that can be detected in the experiment with a given resolution: R max = 3.5/q min ≈ 60 nm. Thus, the observed scattering patterns are typical for scattering from system possessing a disordered porous (solid phase-pore medium) structure with fractal phase boundaries [83][84][85] including natural systems represented by rock fragments from shallow soils [86] and soil aggregates from mature soils [87].…”

Synthesis, Crystal Structure, and Thermophysical Properties of ZrTiO4 Nanoceramics

“…In modern materials science, in addition to solidphase synthesis methods as conventional methods to obtain pre-ceramic materials [29,[34][35][36], there is a tendency to use methods related to the category of "soft chemistry" [1,6,8,12,39,40], leading to a decrease of crystallite size, which, as a result, often promotes the decrease of the temperature of ceramic formation and changing the characteristics of the material.…”

“…Thermal conductivity measurements. The thermal conductivity (λ) of the ZrTiO 4 nanoceramics was calculated using the equation [5]: (1) where α is thermal diffusivity, c p -specific heat capacity, ρ-density. The thermal diffusivity was measured λ = α ρ , p c by the laser flash method on NETZCSH LFA 457 apparatus in the temperature ranges of 25-800°C in nitrogen (N 2 ).…”

“…Materials based on zirconium titanate are of significant interest due to a wide range of applications . As an example, ZrTiO 4 can be drawn on as a material for a chemo-resistive gas sensor [1], an element of hydrophilic ultrafiltration membranes [2][3][4], catalysts and catalyst carrier [5][6][7][8][9]. In the literature, functional materials based on zirconium titanate are demonstrated as promising candidates for application in optics [10][11][12][13][14], medicine [15,16], microelectronics [17,18], and other branches of industry and technology [19][20][21][22][23][24][25][26][27][28][29].…”
