Summary: Rare-earth nickelates exhibit interesting properties for oxide-based electronic devices, including intrinsic charge and orbital orders, and electron-lattice coupling. This study shows that by varying oxygen pressure during the growth of NdNiO3-delta (NNO) films, the magnetic state and resistance can be significantly altered. X-ray spectroscopy measurements reveal changes in Ni2+ ions proportion and preferred orbital occupation with decreasing oxygen pressure.

Summary: The spin state of Co ions in epitaxial LaCoO3 thin films under tensile strain has been determined to have mixed high-spin and low-spin states, while it is practically a low-spin state under compressive strain. The identification of this spin state ratio explains the origin of ferromagnetism in LaCoO3 films. This study highlights the importance of spin state degrees of freedom and thin-film strain engineering in creating new physical properties that do not exist in bulk materials.

Summary: In this work, LaNiO3 epitaxial thin films were deposited on (001) single-crystal LaAlO3 and SrTiO3 substrates using polymer assisted deposition method. Additionally, LaNiO3 polycrystalline film was coated on ceramic substrate using LaNiO3 powder obtained from precursor solution in polymer assisted deposition. The lattice mismatch between LaNiO3 and single-crystal substrates results in the distortion of NiO6 octahedrons, which increases with the intensity of strain and enhances the visible-light photoconductivity.

Summary: Understanding the relationship between the structural characteristics and functional properties of complex relaxor ferroelectric thin films is crucial for designing high-performance materials. This study analyzed the structure of epitaxial relaxed pulsed-laser-deposited PMN-xPT thin films and revealed the preference of the tetragonal-like ferroelectric phase with polarization perpendicular to the film. The results were supported by electromechanical property measurements, showing a locally non-centrosymmetric structure.

Summary: We investigated the proximity effect between ferromagnetic and charge-ordered antiferromagnetic bilayer thin film samples. The results showed that decreasing the thickness of the ferromagnetic layer led to a decrease in both the ferromagnetic transition and metal to insulator transition temperature, an increase in magnetic moments and coercivity. The transport measurement revealed that LSMO remained insulating at low temperatures for a thickness as small as 5 nm. Additionally, a 2 nm thick LSMO bilayer thin film exhibited insulating behavior up to 50 kOe and showed a clear metal to insulator transition when a magnetic field greater than or equal to 70 kOe was applied.

Summary: The epitaxial La0.85Sr0.15MnO3 films on SrTiO3 substrate exhibit both antiferromagnetism and a metallic state below 40 K, with a spin-flop transition observed in the hysteresis loop. The large magnetoresistance around 100 K is attributed to spin scattering at phase boundaries between the ferromagnetic and antiferromagnetic phases. This work contributes to the understanding of magnetic coupling and magneto-transport properties in lightly doped manganite films.

Summary: By utilizing x-ray absorption near-edge spectroscopy (XANES) measurements, we investigated the electronic structure of perovskite-type RCrO3 (R = La, Nd, Eu, Gd, Dy, and Y) compounds. The results showed significant differences in the framework of the metal-oxygen hybridization caused by different rare earth elements (R). The dominant role of Cr3+ was found in all these perovskite-type RCrO3 samples, except for EuCrO3 where Cr existed in a mixed-valence state of +3 and +4. The ligand field-splitting values increased consistently with decreasing rare-earth (R) cationic radii, except for an anomaly in the case of Eu.

Summary: Development of clean and sustainable renewable energy sources is crucial for addressing future energy crises. Noble metals have been used as electrocatalysts to improve efficiency in energy storage/conversion systems, but their high cost and scarcity have driven researchers to explore cost-effective alternatives such as perovskite oxide nanomaterials. This review discusses the importance of perovskite oxide nanomaterials as electrocatalysts for oxygen evolution reaction (OER), including reaction mechanisms and activity descriptors. The article also summarizes experimental instrumentation, parameters, and protocols, as well as recent activation strategies to enhance the electrocatalytic performance of perovskite oxides. The challenges and prospects discussed in this review may lead to the rational design of highly active and stable perovskites as superior alternatives to noble metal-based OER electrocatalysts.

The unique structure led to improved light absorption and efficient degradation of pollutants.

Summary: This study investigates the structural evolution of BiPO4 under different synthesis conditions and explores its electrochemical performance for supercapacitor applications. The addition of different templates (CTAB, SDS) results in a hexagonal structure, while the addition of EG leads to a mixed structure of both the hexagonal and monoclinic phases. Raman spectra confirms the presence of the mixed phase and electron microscopy reveals the influence of templates on the morphology of the synthesized materials. The BiPO4-EG mixed structure exhibits the highest specific capacity, good capacitance retention at high current densities, and the lowest electrochemical series resistance.

Summary: Intense red-emitting double perovskite Sr3LiSbO6 (SLSO) phosphor materials doped with Eu3+ rare earth ion were prepared using a solid-state reaction. The obtained sample displayed a hexagonal structure with space group R3c. The optical band gap of SLSO: 2%Eu3+ was found to be 3.42eV, lower than that of pure SLSO (3.5eV), exhibiting a negative Burstein Moss effect. Concentration quenching effect was observed in the photoluminescence emission spectra beyond 2mol% Eu3+ doping concentration, indicating dipole-dipole interaction. The prepared phosphor had an average decay time of 808.6 mu s. Photometric studies showed low correlated color temperature (CCT) values (<1900K) with high color purity (CP) of 99% and Commission International de'Eclairage (CIE) coordinates in the red region. These results suggest that the proposed phosphor could be a promising strong red-emitting phosphor for white light-emitting diodes (wLED) based on UV or blue chip.

Summary: We successfully fabricated a BiOBr/ZnWO4 heterojunction and found it to have enhanced photocatalytic performance for degrading Rhodamine B dye. Structural and microstructural analysis showed that the heterostructures consist of a mixed tetragonal/monoclinic phase with enhanced surface area. The results indicated that the BiOBr/ZnWO4 heterostructure had a higher degradation rate compared to BiOBr due to higher surface area, pore size, and better electron-hole pair separation efficiency.

Summary: Various faulty farming practices and low-performance cultivars selection are reducing crop yields, factor productivity, and soil fertility. Therefore, efficient nutrient management and selecting nutrient-responsive cultivars are needed to achieve better productivity, seed quality, nutrient efficiency, and soil nutrient dynamics. The study showed that the lentil cultivar HM-1 performed significantly better than Sapna and Garima in terms of seed yield and nutrient uptake, as well as partial factor productivity, partial nutrient balance, and internal utilisation efficiency. It was found that 50% of the recommended fertilizer dose could be substituted with organic manures without compromising crop productivity and soil fertility when growing the HM-1 cultivar, thereby sustaining soil-human-environment health.
