Summary: In this study, nickel substituted cobalt nano-ferrites were synthesized using forced hydrolysis methods, resulting in a decrease in the anisotropy constant and blocking temperature due to the gradual increment of Ni2+ ions. The superparamagnetic behaviour observed above the blocking temperature could make the material a promising candidate for storage devices in quantum technologies.

Summary: In this study, the magnetic properties of ferritin, the primary storage protein in the body, were systematically studied using diamond-based quantum spin relaxometry. An anomalous magnetic behavior was observed at relatively low iron loads due to a morphological change in the iron core of ferritin. The inclusion of this morphological change in a theoretical model was supported by electron microscopy studies and provided evidence for the magnetic consequence of the morphological change.

Summary: Innovation of photocatalysts with acceptable performance and easy recyclability through magnetic separation is a crucial challenge for researchers, as these materials have the potential to improve environmental health. Fe2O3 nanostructures were effectively loaded onto ZnS/ZnIn2S4 nanocomposites via a glycothermal process. The study investigated the impact of the amount of Fe2O3 nanostructures on the structural, physical, magnetic, and photocatalytic properties of the resulting nanocomposites. The magnetic recyclable photocatalysts exhibited a flower-shaped microstructure assembled from nanosheets. The ZnS/ZnIn2S4/Fe2O3 nanocomposites showed higher saturation magnetization than the binary ZnS/ZnIn2S4 nanocomposites. Photocatalytic decolorization experiments demonstrated high removal efficiencies for Rhodamine B and Methyl orange solutions using the ZnS/ZnIn2S4/Fe2O3 nanocomposites. Additionally, the nanocomposites could be easily separated and recycled multiple times with a degradation efficiency of 60.83%. The magnetic ZnS/ZnIn2S4/Fe2O3 nanocomposites are suitable for large-scale applications in industrial water treatment systems.

Summary: The synthesis of optoelectrically enhanced nano-materials should be continuously improved. The porous zinc oxide (ZnO) and copper-doped ZnO nanocomposites (NCs) were successfully synthesized by the time-and energy-efficient solution combustion synthesis (SCS) approach. The doping and heterojunction strategy improved the optoelectric properties of the NCs more than the individual constituents, enhancing the charge transfer and optical absorption capabilities. The SCS approach offers a less expensive and more efficient method for various applications, such as catalysis and sensors.

Summary: Tb3+/Eu3+ doped Bi2Sn2O7 phosphors were synthesized using a co-precipitation method. XRD patterns and TEM images confirm that the phosphors are single phase and consist of irregular nanoparticles. The phosphors exhibit characteristic photoluminescence when singly doped with Tb3+ or Eu3+, while codoped phosphors show tunable photoluminescence due to energy transfer from Tb3+ to Eu3+. The emission color can be adjusted from green to yellowish-red by varying the Eu3+ concentration.

Summary: Black 3D-TiO2 nanotube arrays were successfully fabricated on titanium meshes using an electrochemical reduction method. The optimized arrays showed a maximal photocurrent density of 1.6 mA/cm(2) and a Faradic efficiency of 100%, four times higher than that of pristine 3D-TiO2 NTAs. The improved water splitting activity is attributed to the introduction of oxygen vacancies, which shrink the bandgap and enhance visible light utilization.

Summary: A series of Sr3Y2Ge3O12 based phosphors were synthesized by a solid-state-reaction method. The prepared phosphors exhibited a cubic phase and homogeneous elemental distribution. Bi3+ activated phosphors emitted narrow cyan light under UV excitation, while Cr3+ activated phosphors emitted broad NIR light under blue excitation. Energy transfer from Bi3+ to Cr3+ occurred in the Bi3+/Cr3+ co-activated phosphors, leading to the generation of NIR emission under UV excitation.

Summary: Fe-doped LiNbO3 thin films were successfully deposited on Si (111) substrates by RF magnetron sputtering technique. XAS analysis revealed the incorporation of Fe ions into the LiNbO3 lattice with mixed-valent state. SQUID results showed that the films exhibited room temperature ferromagnetism, with maximum magnetic moment at 7 at% Fe-doped concentration. The room temperature ferromagnetism observed in Fe-doped LiNbO3 films can be attributed to super-exchange and double-exchange interactions mediated by oxygen ions.

Summary: Constructing a TiO2 phase junction with visible light response and effective separation and transfer of photogenerated charges is achieved by fabricating 3D-TiO2 nanotubes arrays-based phase junction with anatase core, rutile shell, and oxygen vacancies. The synergistic effect of the phase junction and oxygen vacancies enhances the separation and utilization efficiency of visible light, and the oxygen vacancies also improve the electrical conductivity for more efficient charge separation and transfer. The optimized 3D-TiO2 NTAs-based phase junction shows significantly improved photocurrent density and Faradic efficiency compared to pure anatase 3D-TiO2 NTAs, making it a promising material for applications in solar cells and photocatalysis.

Summary: Magnetic-based microfluidic SERS biosensors have great potential in biological analyses due to their easy manipulation, miniaturization, and ultrasensitivity. However, collecting reliable SERS nanoprobe signals for quantitative analysis is challenging due to the irregular aggregation of magnetic carriers. In this study, magnetic/plasmonic hybrid nanostirrers embedded with a Raman reporter are developed to improve the reliability of microfluidic SERS biosensors. Experimental results showed that SERS signals from the magnetic hybrid nanostirrers could serve as microenvironment beacons, and a signal filtering method was proposed to eliminate the influence of irregular aggregation on the SERS nanoprobe.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
