Summary: This study investigates the mechanisms of strain and texture observed in MAPbI(3) thin films deposited on various oxide substrates. The results show that the strain of the perovskite layers is essentially relaxed behavior, contradicting the commonly accepted hypothesis. The texture in the perovskite layers is studied using synchrotron full-field diffraction X-ray microscopy, and the stability of different orientations is analyzed by DFT calculations.

Summary: Pulsed laser deposition was used to fabricate SnO2 and SnO2-TiO2 composite thin films on FTO substrates. The addition of TiO2 affected the structural, optical, dielectric, and ac conductivity of the films at room temperature. The composite films had a higher band gap energy and exhibited blue emission bands due to oxygen vacancies or interstitial oxygen ions and defect-related states.

Summary: This study investigated the impact of post-deposition annealing parameters on RF sputtered Zn0.85Mg0.15O thin films, showing that high temperature annealing facilitated Mg incorporation in ZnO lattice and increased grain size due to grain aggregation. High activation energy and narrow line width were achieved in the 900 degrees C annealed film, with the dissociation of bound exciton peaks observed at increasing annealing temperatures.

Summary: Halide perovskite Cs3Cu2I5-based nanocrystals and bulk crystals have been shown to be sensitive and efficient scintillators for X-ray and gamma-ray detection. Undoped and Tl-doped Cs3Cu2I5 microcrystalline films were synthesized and both exhibited lower scintillation efficiency compared to CsI:Tl thin film, but with afterglow signals significantly lower.

Summary: The correlation between depolarization temperature, ergodicity, and piezoelectricity of niobium-substituted (Na0.41K0.09Bi0.50)TiO3 has been investigated. The dielectric measurements show a significant reduction in depolarization temperature and critical transition temperatures with increasing niobium content. The piezoelectric coefficients increase reasonably for compositions with niobium content less than 0.5 mol%, but decrease significantly for more niobium content than 1.0 mol%.

Summary: The changes in substituted La0.5Sr0.5FeO3_ & gamma; orthoferrite under vacuum annealing in the temperature range of 200-650°C were investigated using X-ray diffraction, Mössbauer spectroscopy, and Raman spectroscopy. The annealing process resulted in a transition from rhombohedral to cubic structure at 650°C. The presence of oxygen vacancies and Fe4+ ions in the local environment of Fe3+ ions contributed to the variations observed in the Mössbauer spectra.

Summary: This study investigates the phase transitions in Mg-Ag-Sb thin films produced by magnetron sputtering. The results show that using a single alloyed target or co-sputtering three elements cannot produce homogeneous alpha-MgAgSb films. It is also found that the composition of the phases alpha-MgAgSb and gamma-MgAgSb vary during annealing, contrary to previous beliefs.

Summary: In this study, Fe (acceptor) and Nb (donor) doped PZT films were compared to undoped PZT films in terms of their electrical properties. It was found that the doping significantly affected the remnant polarization, coercive field, and potential barriers at electrode interfaces. The dielectric constant was higher in the doped films, but the effective density of charge carriers was similar. Additionally, PFM investigations revealed that the orientation of polarization differed between Fe-doped and Nb-doped PZT films, which could be attributed to the change in conduction type.

Summary: In this study, photoelectron spectromicroscopy data cubes with sub-micrometer spatial resolution were used to investigate the correlations between fitting parameters in different areas of a lead zirconate titanate thin film. The results suggest that surface band bending can manifest in samples with multiple polarization states. Furthermore, the analysis of correlations between parameters provides deeper insights into the distribution of band bending, allowing for the discrimination of different components and the establishment of correlations between areas with different polarization.

Summary: Research shows that resistive or capacitive non-ferroelectric elements have a significant impact on switching behavior, leading to an increase in the apparent coercive field or imprint. The observation of negative capacitance regimes depends on the nature of the non-ferroelectric element, and the voltage on the ferroelectric component remains constant during the switching process, reflecting the system passing through non-equilibrium states.

Summary: Bacterial cellulose (BC) is a biopolymer studied intensively for biomedical applications. However, it lacks antimicrobial activity and has limited water retention capacity. To address these limitations, BC composites with carboxymethyl cellulose (CMC) and turmeric extract (TE) were developed using citric acid (CA) as the crosslinking agent. These composites showed high swelling degrees, adsorbing exudate from chronic wounds, and exhibited potential antibacterial properties against Escherichia coli, Staphylococcus aureus, and Candida albicans. The composites were also found to be non-toxic to fibroblast cells, making them promising candidates for wound dressing applications.

Summary: This study focuses on the fabrication and characterization of composite scaffolds based on polycaprolactone (PCL) and cerium (Ce)-containing powders. The composite scaffolds showed good biological activity and antibacterial effect. The scaffolds were composed of either dimensionally homogeneous fibers or mixtures of fibers with a wide size distribution and beads of different shapes. The immersion in simulated body fluid (SBF) triggered the degradation of PCL, mainly through cracks and gaps. The composite scaffolds exhibited excellent biocompatibility, with the samples consisting of PCL and Ce-doped calcium phosphates showing superior performance.

Summary: In this study, we measured the properties of a metal-free molecular perovskite material and found that it exhibits ferroelectricity below a certain temperature. We also observed that the material deteriorates and loses mass at high temperatures, leading to a decrease in performance. Unlike traditional ferroelectric materials, the elastic modulus of this material weakens before the ferroelectric phase. The degradation of the material is attributed to point defects, and a method for calculating the defect concentration is proposed.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.
