A nanoscale-driven crystal growth of magnetic hexaferrites was successfully demonstrated at low growth temperatures (25-40% lower than the temperatures required often for crystal growth). This outcome exhibits thermodynamic processes of crystal growth, allowing ease in fabrication of advanced multifunctional materials…
Abstract In this work, ceramic NbTi 0.5 Ni 0.5 O 4 is reversibly transformed to nickel‐anchored electronic‐conducting Nb 1.33 Ti 0.67 O 4 composite for the use of direct carbon dioxide electrolysis at intermediate temperatures. The reduced composites Nb 1.33 Ti 0.67 O 4 + Ni demonstrate excellent electrical properties…
Self-assembled monolayers of thiols on gold are employed to study the role of surface chemistry on adsorption of polyelectrolytes to solid substrates. The suitability of these substrates is demonstrated in optical reflectivity, which combines high sensitivity to the possibility to precisely control the hydrodynamic co…
The resistivity of vanadium dioxide $({\mathrm{VO}}_{2})$ decreased by over one order of magnitude upon localized illumination with x rays at room temperature. Despite this reduction, the structure remained in the monoclinic phase and had no signature of the high-temperature tetragonal phase that is usually associated…
We describe the transmission characteristics for the interaction of an arbitrary beam with (possibly multilayered) spherical particles of arbitrary size and electric permeability. Within the generalized Lorenz-Mie theory, expressions that generalize the total cross sections to their fractional counterparts are present…
In this work we report the dispersive behavior of the most characteristic Raman contributions of highly oriented pyrolytic graphite at biaxial stresses up to 10 GPa, using a moissanite anvil cell as a pressure device. The stress coefficients and the relative Grüneisen parameters are obtained for two different excitati…
ABSTRACT This work is a comprehensive study of the effect of extrusion process parameters and formulation on the properties of polypropylene (PP)/short flax fiber composites. The parameters that were varied during the twin‐screw extrusion process were screw configuration, revolutions per minute (rpm), extrusion temper…
Abstract A 30‐cell solid oxide electrolysis (SOE) stack consisting of 30‐cell planar Ni–YSZ hydrogen electrode‐supported single cell with La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3– δ –Ce 0.9 Gd 0.1 O 1.95 (LSCF–GDC) composite oxygen electrodes, interconnects, and sealing materials was tested at 750 °C in steam electrolysis mode…
In an attempt to employ salicylic acid (HOsalH), 2,6-dihydroxy benzoic acid {(HO)2PhCO2H}, and naphthalene-1,8-dicarboxylic acid {1,8-naph(CO2H)2} in Mn(III) salicylaldoximate chemistry as a means to alter the structural identity of the hexanucluear clusters usually obtained from this reaction system, we have isolated…
Hyperbranched polyether was synthesized and vinyl modified using the one-pot method and characterized by Fourier transform infrared spectroscopy (FTIR), hydrogen nuclear magnetic resonance spectroscopy, and thermogravimetric analysis (TGA). The as-obtained polyether was used to cross-link hydroxyl-terminated polybutad…
Abstract The ammonoacidic crystal growth allows industrial production of bulk semiconductor materials like gallium nitride as a widely known material for applications in photonics. A limitation of this process is strong corrosion of the growth autoclave which consequently leads to high impurity density in grown crysta…
ABSTRACT A series of thermally stable lanthanum organic montmorillonites (La‐OMMTs) were successfully prepared by modifying Na‐MMT with anionic surfactants and lanthanum chloride. Fourier transform infrared spectroscopy and X‐ray diffraction indicated that the anionic surfactants resided in the interlayer spaces and e…
Abstract Dynamic light scattering experiments performed on precrystalline liquid solutions that shows oiling‐out at higher vanillin concentration resulted in scattering from assumed precrystalline clusters. The structures appear during crash‐cooling into the supersaturated area and grow to µm size. They decrease in si…
Abstract The gas‐phase fragmentation reactions of Keggin‐type [PW 11 O 39 MCl] 5– (M = Rh, Ir) polyoxometalates (POMs) featuring chloride terminal ligands have been investigated. Different adducts of the general formulas [PW 11 O 39 MCl + 2cat] 3– and [PW 11 O 39 MCl + 3cat] 2– [cat = alkylammonium cations (Me 4 N + ,…
Introduction to Crystal Growth: Principles and Practice teaches readers about crystals and their origins. It offers a historical perspective of the subject and includes background information whenever possible.The first section of this introductory book takes readers through the historical development and motivation o…
A thermomagnetic processing method was used to produce a biphenyl-based liquid-crystalline epoxy resin (LCER) with oriented liquid-crystalline (LC) domains. The orientation of the LCER was confirmed and quantified using two-dimensional X-ray diffraction. The effect of molecular alignment on the mechanical and thermome…
The Kondo effect and ferromagnetism are the two many-body phenomena that emerge at the SrTiO(3) interfaces with polar materials, but do not occur in bulk SrTiO(3). By regarding the oxygen vacancy (OV) in SrTiO(3) as a magnetic impurity, we show that these two interface-specific phenomena can be attributed to the vacan…
We have studied the transport properties of TEM lamellae obtained from a pyrolytic graphite sample with electrical contacts at the edges of the embedded interfaces. The temperature dependence of the resistance as well as the current-voltage characteristic curves are compatible with the existence of Josephson coupled s…
In this paper, we investigated the functional imaging properties of magnetic microspheres composed of magnetic core and CdTe quantum dots in the silica shell functionalized with folic acid (FA). The preparation procedure included the preparation of chitosan-coated Fe3O4 nanoparticles (CS-coated Fe3O4 NPs) prepared by…
Polylactic acid (PLA) is the most promising material in the biodegradable category. However, brittleness and poor thermal stability restrict its application. To overcome this limitation, PLA may be blended with other biodegradable materials to tailor its properties while maintain biodegradability. In this study a seri…
