Summary: LaFe11.8Si1.2/16wt%La65Co35 samples were prepared by spark plasma sintering (SPS) and subsequent annealing. The La65Co35 binder increased the 1:13 phase content, and the alpha-Fe phase formed and disappeared during annealing. The sample annealed for 0.5 h showed a distinct core-shell structure, desirable table-like (-Delta S-M) -T curve, and higher RC value. The diffusion of Co was hindered by the growth of La5Si3 phase. Samples annealed for 24 h achieved larger (-Delta S-M)(max) and (sigma(bc))(max) values. The method combining SPS and diffusion annealing is promising for preparing La-Fe-Si based magnetocaloric composites with good properties.

Summary: EuGd2O4 and EuDy2O4 exhibit a remarkably large magnetocaloric effect at cryogenic temperatures due to their high magnetic density and low ordering temperatures. The antiferromagnetic ordering of Gd derivative at T-N = 4.6 K exceeds that of the reference refrigerant GGG above 5 K. EuDy2O4 has a lower magnetocaloric effect than EuGd2O4, yet larger than GGG.

Summary: Ni 43Mn 46Sn11-xTex(x = 0.1, 0.2, 0.3, 0.4, 0.5, 1) alloys were prepared by arc melting. Structural studies revealed the presence of L21 cubic austenite phase. The martensite phase and lattice constant decrease with increasing Te concentration. All alloys exhibit first-order phase transition. The martensite temperature increases successively with increasing Te concentration. A non-linear magnetic entropy change and thermal hysteresis were observed with increasing Te concentration. The magnetocaloric effect was observed over a broad temperature range by varying the Te concentration. The tunable martensite temperature and magnetocaloric properties with Te concentration make these alloys useful for magnetic refrigeration applications.

Summary: Single-phase La0.7Sr0.3Mn1-xFexO3 perovskites were synthesized by sol-gel method and had a rhombohedral structure with a slight change in lattice parameters and unit cell volume. The average particle size ranged from 43-70 nm. The samples exhibited a ferromagnetic to paramagnetic second-order magnetic phase transition at TC, which decreased linearly with Fe doping. XPS measurement confirmed the oxidation states of Fe and La as +3 and a mixed valence state of Mn4+/Mn3+. The Fe substitution suppressed the saturation magnetization and blocking temperature, while (-4SM)max decreased with increasing Fe content. The sample with x = 0.08 showed a Curie temperature of 297 K, the highest relative cooling power (RCP) of 153 J/kg, and (-4SM)max value of 1.46 J/kg.K at mu o4H = 2.8 T. The La0.7Sr0.3Mn1-xFexO3 manganites are potential candidates for room-temperature magnetic refrigeration applications.

Summary: In this study, the cyclic reversibility of the martensitic transformation and magnetocaloric effect in a Ni51.0Mn20.8Ga22.4Cu5.8 alloy was investigated. The martensitic transformation showed small hystereses and excellent reversibility upon 50 thermal and magnetic cycles due to the good geometric compatibility of the martensite/austenite transferring interface. A reversible magnetic entropy change of -21.7 J/kgK was achieved under 50 kOe after performing 50 magnetic cycles, indicating the excellent reversibility of the magnetocaloric effect in the alloy.

Summary: This work presents a theoretical description of the second-order magnetic transition and magnetic entropy change of La0.65Ce0.05Sr0.3Mn1-xCuxO3 (x = 0 and x = 0.15) compounds based on the Bean-Rodbell model. The magneto-caloric properties obtained from initial magnetization isotherms data are in good agreement with numerical simulations. Cu-doping is found to increase the spin-lattice interactions and spin value fluctuation, which is attributed to the disorder induced by Cu2+/Cu3+ ions in the system.

Summary: Zinc substituted nickel-cobalt ferrites with average crystallite size 100 nm were synthesized and their effects on structural and dielectric properties were investigated. The results show that the dielectric responses of Zn substituted ferrites are frequency dependent and thermally activated. The presence of non-Debye type dielectric relaxation was observed, and the rise in Zinc concentration leads to a decrease in dielectric constant. The low loss tangent factor and high activation energy make Zn(0.2)Co(0.2)Fe(2)O(4) suitable for high frequency-applications at room temperature.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
