Summary: This study investigated the magnetotactic advantage of two wild type MTB in a sedimentary environment. The cocci displayed a larger temporal variability, while the concentration of M. bavaricum decreased significantly and cocci almost went extinct in zero field. The findings also revealed a potential different magnetotactic mechanism for M. bavaricum in surviving field reversals in geological periods.

Summary: Nanoparticles are commonly added to polymer electrolytes to enhance their mechanical and ion transport properties. This work carefully controls the dispersion state of silica nanoparticles in a model polymer electrolyte system and finds that controlling the dispersion leads to improved mechanical properties while reducing the ionic conductivity. These results suggest that achieving increases in bulk, ionic conductivity requires percolating aggregates of ceramic surfaces.

Summary: This study focuses on the characterization of a series of solid nanocomposite polymer electrolytes consisting of PEO, POSS, and LiBOB. The addition of LiBOB and POSS leads to a decrease in the crystallinity and melting temperatures of PEO, while the glass transition temperatures increase. The thermal stability of the polymer electrolytes was investigated, showing a more complex degradation compared to pure PEO. However, the polymer electrolytes remain thermally stable enough for their applications in electrochemical devices. The incorporation of LiBOB and POSS positively influences the ionic conductivity of PEO. The optimized system was determined based on the ionic conductivity of the nanocomposites.

Summary: In this study, hybrid ruthenium-decorated superparamagnetic iron oxide nanoparticles were designed as contrast agents for both magnetic resonance imaging (MRI) and X-ray fluorescence computed tomography (XFCT). These nanoparticles were synthesized through a one-pot polyol hot injection method. In vivo preclinical studies showed the possibility of correlative bioimaging using these contrast agents. The complementary nature of MRI and XFCT allowed for accurate localization and high specificity and resolution in nanoparticle detection, suggesting potential applications for early tumor diagnosis, improved long-term treatment monitoring, and enhanced radiotherapy planning.

Summary: Silver nanoparticles (Ag NPs) have been found to effectively inhibit SARS-CoV-2 infection, particularly the unmodified nanoparticles. This study also showed that the Ag NPs retained their antiviral properties even after pre-incubation with pulmonary surfactant. Additionally, the Ag NPs disrupted the secondary structure of the spike protein of SARS-CoV-2, while ionic control (AgNO3) and TiO2 nanoparticles did not have the same effect. Moreover, the Ag NPs were non-cytotoxic to human lung epithelial cells and nasal epithelial cells.

Summary: Superparamagnetic iron oxide nanoparticles (SPIONs) play a dominant role in various biomedical applications, including magnetic separation, drug delivery, diagnostics, and hyperthermia treatments. In this study, superparamagnetic nanoclusters (SP-NCs) with high unit magnetization and diameters up to 400 nm were synthesized using conventional or microwave-assisted solvothermal methods. The choice of synthesis route and capping agent significantly influenced the particle size, SP-NC size, surface chemistry, and magnetic properties. The SP-NCs were then coated with a silica shell doped with a fluorophore to provide fluorescence properties and high stability. The heating efficiency studies demonstrated the potential of these synthesized SP-NCs in hyperthermia treatment. The enhanced magnetically-active content, fluorescence, magnetic property, and heating efficiency of SP-NCs offer promising opportunities for biomedical applications.

Summary: In this study, we investigated the effect of Ir substitution into Fe sites on the band gap of LuFeO3 material. LFO and Ir-doped LFO (LuFe1-xIrxO3 or LFIO for short, where x = 0.05 and 0.10) thin films were synthesized using magnetron sputtering techniques. The crystallographic orientation and surface topography of the films were examined using X-ray diffraction (XRD) analysis and atomic force microscopy (AFM), respectively. Photoluminescence (PL) spectroscopy was used to study the recombination of photogenerated electron-hole pairs, while Raman spectroscopy provided information on crystal symmetry and defects in the oxide materials. It was found that the LFO band gap could be changed from 2.35 to 2.72 eV by Ir substitution into Fe sites. In addition, diffuse reflectance spectroscopy (DRS) was employed to analyze various optical properties of the materials.

Summary: LuFe1-xOsxO3 (x = 0, 0.05, and 0.10) compounds were synthesized and their resistivity, impedance, and frequency-dependent loss tangent were investigated at different temperatures. Impedance and resistivity increased with the doping procedure, while activation and loss tangent values decreased. X-ray photoelectron spectroscopy (XPS) revealed the oxidation state of Lu and peaks for lattice oxygen and oxygen vacancy. Scanning electron microscopy (SEM) images showed particle agglomeration and void formation. Single and double oxygen vacancies and ion hopping were responsible for the reported activation energies. The compounds exhibited a low loss factor even at high temperatures.

Summary: Due to its electrical, magnetic, and optical characteristics, LuFeO3 (LFO) has garnered interest from the scientific community. This study prepared powders of LFO, LuFe0.95Co0.05O3, and LuFe0.90Co0.10O3 samples using the solid-state approach. Characterization techniques such as XRD, SEM, and XPS were employed to analyze the samples' crystalline structure, particle size, and oxidation states of Fe and Co. The undoped LFO sample exhibited higher conductivity and dielectric constant compared to the Co-doped LFO samples. Magnetic experiments using VSM showed that Co doping increased the Mr values, which could be attributed to variations in the inclined angles of Fe3+ moments and the growth of magnetocrystalline anisotropy's energy.
