Summary: A series of single-phase nickel-substituted magnesium spinel ferrites were synthesized using the hydrothermal technique, and their morphology, structure, magnetism, and electrochemical properties were investigated. Experimental characterization techniques confirmed the presence of a single-phase spinel structure, with a decrease in lattice parameter and clustering of nanoparticles as nickel concentration increased. Raman and FTIR spectra indicated changes in wave numbers and the shortening of Fe-O bonds. Additionally, the ferrites exhibited increased saturation magnetization, decreased coercivity, decreased specific capacitance, and increased loop size. These ferrites are promising for energy storage applications.

Summary: This study examines the differences in electrochemical performance of V2O5 insertion electrodes with different crystal structures. The results show that the tunnel-structured V2O5 electrode has a simpler insertion mechanism and better battery performance compared to the layered V2O5 electrode, which undergoes a series of phase transformations and distortions, resulting in larger voltage hysteresis and capacity loss.

Summary: The glycosylation of egg white proteins with maltodextrin was studied. The glycosylated egg white proteins showed improved gel properties, such as increased hardness, water holding capacity, rheological parameters, and finer gel microstructures. The protein structures were unfolded due to glycosylation, as observed by changes in content of exposed sulfhydryl group and β-sheet, decreased crystallinity, thermal denaturation temperature, and enthalpy. The study provides insights into glycosylation mechanism and a convenient approach to improve the gel properties of egg white proteins.

Summary: The glycosylation of egg white proteins with maltodextrin was studied and the resulting glycosylated proteins showed improved gel properties such as increased hardness, water holding capacity, rheological parameters, and finer microstructures. The protein structures were unfolded due to extended glycosylation, as evidenced by increased exposed sulfhydryl groups and beta-sheet content, decreased crystallinity, thermal denaturation temperature, and enthalpy. The gel properties were correlated with the structural changes. Overall, this study provides insights into the mechanism of glycosylation and offers a convenient approach to enhance the gel properties of egg white proteins in the food industry.

Summary: In this study, a multi-scale correlative approach was used to compare artificially demineralised human enamel with healthy enamel, revealing structural differences at the micron to sub-micron scale. The decrease in Ca/P atomic % ratio in etched samples compared to healthy enamel, as shown by energy-dispersive X-ray spectroscopy, suggests greater loss of calcium. Synchrotron wide-angle X-ray scattering was employed to analyze differences in lattice structure and texture before and after etching, providing insights into the demineralisation-induced enamel structure alteration.

Summary: The crystallization behavior of a Cu58Y37Sc5 metallic glassy alloy was investigated using various methods. Differential scanning and isothermal calorimetries were performed to study the phase transformations. X-ray diffractometry studies showed the simultaneous formation of Cu2Y, CuY, and CuSc crystalline phases, indicating eutectic crystallization, while the isothermal crystallization kinetics corresponded to primary crystallization. Transmission electron microscopy observations revealed a complex crystallization process involving heterogeneous nucleation on pre-existing particles.

Summary: A comprehensive investigation into the cocrystallization of carbamazepine (CBZ) has been conducted, exploring different synthesis methods and stoichiometric compositions. Thermodynamic and structural analysis has allowed for a comparison of CBZ cocrystals obtained from different coformers, as well as an assessment of the impact of synthesis methods and stoichiometric ratios. The study has identified reproducible conditions for the crystallization of two different stoichiometries of the carbamazepine/tartaric acid system, as well as a spontaneous solid-solid transformation into a channel-like cocrystalline form. The kinetics of the transformation process suggest that nucleation likely controls the cocrystallization process.

Summary: The use of nanomagnets in biomedical applications has increased in recent years. However, the magnetic anisotropy of individual magnetic nanostructures is still mostly unknown. Current methods for measuring magnetic signals are limited in spatial resolution or magnetic field strength, and cannot be applied to nanomagnets in biological systems. In this study, we present a hybrid experimental/theoretical method to determine the magnetic anisotropy constant and magnetic easy axis of individual magnetic nanostructures embedded in biological systems.

Summary: This study investigates the influence of strain on the microstructure and high-temperature hot corrosion behavior in Alloy 617. The highly strained specimens showed improved resistance to HTHC due to enhanced Cr diffusion and formation of a continuous, compact Cr-rich oxide film. Recrystallization and evolution of Cr-rich carbides in the strained specimens during HTHC testing increased their likelihood of resisting the aggressive environment for a prolonged duration.

Summary: Green chemistry has shown great promise in biomedical applications, particularly in cancer therapy. Chitosan-based nanoparticles (CS-NPs) serve as a promising carrier for anti-cancer drugs, overcoming drug resistance and enabling synergistic therapy. Various types of nanostructures can be modified with chitosan for efficient delivery of chemotherapeutic agents such as doxorubicin (DOX). The functionalization of CS-NPs with ligands and their pH-sensitive and redox-responsive characteristics further enhance their selectivity and drug release. Considering their high encapsulation efficiency and biocompatibility, significant progress is expected in the clinical translation of CS-NPs.

Summary: The sudden rise in gas and oil prices due to political issues, along with the need to reduce CO2 emissions to almost zero by 2050, has prompted scientists to propose renewable and sustainable strategies to replace fossil fuel sources or decrease energy demand. Utilizing thermal energy storage combined with renewable energy sources, particularly solar energy, is a popular approach in reducing peak energy demands. Phase change materials (PCMs), especially bio-based ones, have been studied for their application in various fields such as building heating and cooling, drug delivery, and electronic cooling.

Summary: In this study, Silver-Platinum (Pt-Ag) bimetallic nanoparticles were synthesized using a biogenic reduction method with plant extracts. The reduction method provided a novel approach to obtaining nanostructures with fewer chemicals. The Pt-Ag bimetallic nanoparticles demonstrated an ideal size of 2.31 nm as observed through Transmission Electron Microscopy. Characterization of the nanoparticles was conducted using Fourier Transform Infrared Spectroscopy, X-ray Diffractometry, and Ultraviolet-Visible spectroscopy. Electrochemical measurements using Cyclic Voltammetry and Differential Pulse Voltammetry indicated a limit of detection of 0.03 μM and a limit of quantification of 0.11 μM. The antibacterial properties of the Pt-Ag NPs were also evaluated, showing strong antibacterial effects against Escherichia coli and Staphylococcus aureus bacteria.

Summary: Global waste production is expected to reach 2.59 billion tons by 2030, exacerbating environmental pollution and health safety issues. The inefficient waste management in the circular economy is characterized by 37% landfilling, 33% open discharge or burning, and only 13.5% recycling. Therefore, there is a need for methods to recycle waste into valuable materials through resource recovery, which depends heavily on the development of efficient and reusable nanobiocatalysts.

Summary: This review provides a comprehensive overview of recent advances in molecularly imprinted electrochemical sensors (MIES) for detecting Bisphenol A (BPA). Key findings show that MIES demonstrate comparable or superior detection limits to conventional methods, and exhibit excellent selectivity between BPA and structural analogs. Innovations in nanomaterials, novel monomers, and fabrication techniques have improved the sensitivity, selectivity, and stability of MIES. However, limitations exist in reproducibility, selectivity, and stability. Nonetheless, MIES offer a low-cost portable detection method suitable for on-site BPA monitoring in diverse sectors.
