Summary: Nanosized CeO2-ZrO2 powders prepared by atmospheric pressure pyrolysis were used as raw materials to prepare CeO2-ZrO2 ceramics using microwave sintering. When the CeO2 content is more than 5 mol%, the tetragonal phase peak appears in the sample, and the grain size of the ceramics is negatively related to Ce content. CeO2 reduces the solid solution's phase transformation temperature with microwave heating.

Summary: In this study, SrWO4-x wt.% Li2MoO4 (x = 2.5, 5, 7.5, 10) ceramics were synthesized at low temperature using the solid-state synthesis method. The effect of Li2MoO4 on the crystallization, activation energy, microstructure, and sintering process were discussed in detail. Li2MoO4 significantly reduces the sintering temperature of SrWO4 and promotes the shrinkage and densification of the ceramic at low temperature. Specifically, the SrWO4 ceramics containing 5 wt% Li2MoO4 sintered at 875 degrees C exhibits the most favorable microwave dielectric properties, demonstrating potential applications in the field of low-temperature co-fired ceramics (LTCC).

Summary: Ca1-xBaxMgSi2O6 ceramics were prepared through solid-state reaction sintering, and the effects of substituting Ba2+ for Ca2+, relative density, phase composition, crystal morphology, and microwave dielectric properties were studied. The results showed that a single phase was formed when x ≤ 0.2, while a second phase appeared at x = 0.4. The increase in Ba2+ substitution affected the microwave dielectric properties, with Qxf value first increasing and then decreasing, and epsilon(r) value continuously increasing. The z(f) value also slightly improved.

Summary: This study investigates the microstructure and magnetic properties of a sintered magnet with Ce substitutions. The addition of Ce resulted in lattice contraction, with further increase in Ce content leading to a suppression in lattice contraction. The magnets with higher Ce content exhibited the REFe2 phase at the expense of a reduced mass fraction of the REOx phase. The valence state of Ce changed from a mixed state to a trivalent state, and a bi-layer interfacial structure was formed between the RE2Fe14B and the REFe2 phases.

Summary: A comprehensive study on the structural, electronic, and magnetic properties of Co-substituted Fe2CrSi Heusler alloys was conducted. The effect of rapid solidification on the formation of pure phase Fe2CrSi alloy was also investigated. The results revealed that Fe2CrSi alloys with Co substitution in the range of 0.2 <= x <= 0.5 exhibited a single L21 phase structure, while those with x = 0 and 0.1 had impurity phases coexisting with the L21 phase. The high speed melt-spinning process resulted in higher purity in the alloy samples. First principles calculations showed that the single phase ribbon sample exhibited disorder, indicating a change in site preference due to solidification rate. The magnetic moments of the alloys were consistent with the Slater-Pauling rule. Fe2Cr0.75Co0.25Si alloy was suggested as a promising candidate for spintronic device applications due to its half-metallic nature.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
