Summary: Hybrid improper ferroelectric Ca3Ti2O7 and Ca3Ti19Ru0.1O7 ceramics were successfully synthesized using the conventional solid-state reaction method. The Ru substitution led to changes in the crystal structure, decreased coercive field, and a lower optical bandgap due to impurity energy levels, as supported by first-principles calculations. The unexpected induced magnetic moments in Ru-doped Ca3Ti2O7 are also discussed.

Summary: We investigated the challenging CrCl3 surface using photon energy dependent photoemission (PE). By studying the core and valence electrons of cleaved single crystals in either ultra-high vacuum (UHV) or air, we confirmed the atomic composition with respect to the expected bulk atomic structure. The presence of a stable, but only partially ordered Cl-O-Cr surface was revealed by a common spectroscopic denominator. Through analysis of multiplet components, we quantified the electron charge transfer and the reduced crystal field due to the established polarization field. The methodology used in this study can have a significant impact on determining the structure of ordered sub-oxide phases in mono or bi-layer Cr trihalides.

Summary: Crystals with anisotropic thermoelectric transport coefficients can exhibit high figure-of-merit if the Seebeck coefficient and thermal conductivity are relatively isotropic. In this study, the anisotropic properties of the quasi-1D Zintl phase Ca5In2Sb6 were investigated using both experimental and theoretical methods. The results showed that Ca5In2Sb6 has highly anisotropic p-type electrical conductivity and power factor, while the Seebeck coefficient and lattice thermal conductivity are relatively isotropic. This study provides experimental confirmation of highly anisotropic electrical conductivity in Zintl thermoelectrics.

A high-pressure polymorph of NaYGeO4 with NaNdSiO4 crystal structure was formed at 800 degrees C starting from 6 GPa, and another new high-pressure modification of NaYGeO4 with NaSmSiO4 crystal structure was found in small amount. In addition, a yet undescribed polymorph of Y2Ge2O7 with pyrochlore-type structure was isolated at 8 GPa and 800 degrees C.

Summary: Vanadyl formate monohydrate VO(HCOO)2 center dot H2O was synthesized using a simple two-stage method and its chemical and structural properties were confirmed. Heating in water and ethylene glycol resulted in the formation of vanadyl hydroxide VO(OH)2 and vanadyl glycolate VO(OCH2CH2O). Heating at higher temperatures led to the transformation of VO(HCOO)2 center dot H2O into vanadium pentoxide or sesquioxide. The precursor was used to synthesize nanoscale vanadium sesquioxide with a lower metal-insulator transition temperature than the bulk compound, and the particle size was controlled by the annealing temperature in an inert atmosphere.

Summary: The polycrystalline samples of BaNi2(V1-xPxO4)2 (x = 0-1) were synthesized via a solution combustion synthesis. The substitution of vanadium (5+) cations by smaller phosphorus (5+) cations leads to compression of the [Ni2(V1-xPxO4)2]infinity layers in the ab plane and elongation of the BaO12 polyhedra along the c axis. The melting point of the samples increases with increasing phosphorus concentration. The electrical conductivity of BaNi2(V1-xPxO4)2 is measured and electron transfer is explained by the formation of Ni3+ along the Ni-O-Ni chains.

Summary: Optically transparent Mg1_xMnxAl2O4 (x = 0.005; 0.00005) nanoceramics were synthesized using thermobaric synthesis. The parameters of thermobaric synthesis can be adjusted to control crystallographic parameters and the formation of defects. The synthesis process has two stages with different crystallographic and optical parameters. A correlation between residual strain and scattering coefficient was observed in the optically transparent nanoceramics. Thermobaric synthesis of optical nanoceramics allows for compressing nanosized objects in an optical spinel matrix while keeping them in a metastable state.

Summary: Pb1+хS thin films with a thickness of 190-360 nm were synthesized on glass substrates using different thioamides as sulfur precursors. The films exhibited polycrystalline structure and n-type conductivity. The sulfur origin was found to affect the crystalline structure, morphology, and formation mechanism of the Pb1+хS films. The excess of lead was correlated with the optical band gap, where a greater excess led to a wider band gap. Fractal analysis suggested a cluster-by-cluster association model for the film growth.

X-ray powder diffraction data analysis revealed that these vanadates have a monoclinic crystal structure with space group P2(1)/c, (# 14), Z = 4. The crystal structure of the solid solutions can be considered as a monoclinic distortion of the orthorhombic lattice of Sr2.4-?Co2.6+xP3VO15, which is a rare phenomenon where barium and manganese (2+) cations share an octahedral site coordinated by oxygen ions.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
