Summary: Nanocomposites consisting of 2D amorphous Cr2O3-CoFe(2)O(4) and crystalline 2D Cr2O3-CoFe(2)O(4) were prepared and studied for their room temperature magnetoelectric coupling. The effect of crystalline 2D Cr2O3 on the exchange bias induced magnetoelectric coupling in the composites was also investigated. Evidence of exchange bias in the composites was obtained from FC-ZFC measurements. The 2D crystalline Cr2O3 composite exhibited a higher magnetoelectric coupling coefficient at room temperature compared to the bulk composite of Cr2O3. These composites have promising applications in energy harvesting and spintronics.

Summary: This paper describes the preparation and study of new bifunctional samples (Y(0.9)Ln(0.1)VO(4)/Fe3O4)@SiO2 and [(Y(0.9)Ln(0.1)VO(4)@SiO2)/ Fe3O4@SiO2] with Ln = Nd or Tb. The influence of Fe3O4 content and silica coating on the Y(0.9)Ln(0.1)VO(4)@SiO2 samples is analyzed, and their potential utility is determined. These samples, which have potential applications in biomedicine, can be directed using an external magnetic field and allow the visualization of diseased cells. The experimental and theoretical studies provide insights into the structural and vibrational properties of the samples, confirming the presence of silica coating. The [(Y(0.9)Ln(0.1)VO(4)@SiO2)/Fe3O4@SiO2] samples show the most suitable properties for use as bifunctional materials.

Summary: We report the successful synthesis and magnetic characterization of CoFe2O4@SiO2@Au magnetoplasmonic nanoparticles. The CoFe2O4 magnetic nanoparticles were prepared using the hydrothermal method, and a SiO2 shell and plasmonic Au shell were deposited on the magnetic core to create magnetoplasmonic nanoparticles with a core-shell architecture. The surface of the CoFe2O4 nanograins showed spin-glass-type magnetism, with two types of spin-glass identified depending on the external magnetic field.

Summary: In this study, Cr2O3, Cr2O3-SiO2-TiO2, and Cr2O3-SiO2-TiO2-graphite coatings were prepared using atmospheric plasma spraying. The addition of SiO2-TiO2-graphite resulted in the lowest surface roughness and the most homogeneous surface of the coatings. X-ray diffraction (XRD) measurements showed that all coatings consisted of the eskolaite chromium oxide phase. The Cr2O3-SiO2-TiO2 coating exhibited the lowest friction coefficient, and the addition of SiO2-TiO2 and SiO2-TiO2-graphite decreased the specific wear rates of Cr2O3 coatings by 30% and 45% respectively. The wear resistance was also greatly improved compared to the steel substrate.

Summary: The synthesized CFO-xNFSO nanocrystals exhibit good potential in energy storage applications, showing enhanced capacitance and relatively high energy density in supercapacitor electrodes. The cubic spinel ferrite phase of the NCs is verified by XRD, SEM, and HR-TEM techniques. The magnetic properties of the NCs with different x ratios suggest a good exchange-coupling in the CFO-xNFSO magnetic nanocrystals.

Summary: Hard ferrite (CoFe2O4), soft ferrite (Ni0.8Zn0.2Fe2O4), and composite ferrite (CoFe2O4)x/(Ni0.8Zn0.2Fe2O4)1-x (hard/soft ferrite) with varying compositions were synthesized by sol-gel auto combustion method. X-Ray Diffraction analysis confirmed the formation of cubic structures in the samples. Thermal analysis using TGA/DSC determined the temperature of phase formation. FTIR spectroscopy data verified the successful synthesis and formation of functional groups in the ferrites. SEM characterization showed overlapping spherical particles, and elemental mapping was performed using EDS. FESEM and TEM analysis demonstrated enhanced magnetic hyperthermia properties. Vibrating Sample Magnetometry was used to study the saturation magnetization (Ms), coercivity (Hc), and remnant magnetization (Mr) of the samples. Zeta potential measurement examined the surface charge of the particles in DI water. Heating characteristics of the samples were evaluated in an alternating magnetic field. The magnetic properties depended on the concentration of soft and hard ferrite, and the magnetic heating efficiency depended on the sample composition.

Summary: This study presents a sol-gel auto-combustion method to prepare core/shell structure CoFe2O4(core)/Cr2O3(shell) nanoparticles, and validates their properties through various testing methods. The nanoparticles exhibit responses similar to single domain particles under different molar fraction conditions. Impedance and modulus data analysis shows a single relaxation process in the studied frequency/temperature range, with both relaxation and conduction processes following Mott variable range hopping mechanism. Direct ME measurements demonstrate an increased magnetoelectric operating temperature for the parental Cr2O3 phase, widening its potential applications.

Summary: In this work, the authors demonstrate a label-free electrochemical impedimetric detection method for radiation-induced DNA damage using chiral-induced spin selectivity (CISS) and electrons' spin as a novel sensing tool. They prepared self-assembled monolayers (SAMs) of short ds-DNA on arrays of multilayer thin film devices and exposed them to UVC radiation to induce structural perturbations in DNA. The detection of DNA damage was achieved by recording spin-dependent electrochemical impedimetric spectra, taking into account the correlation between charge-transfer resistance (Rct) and the spin selectivity of electrons through DNA. The authors achieved a limit of detection of 10 picomolar concentrations of DNA, and the method showed robustness against electronic signal perturbation.

Summary: Researchers have designed and built a novel light-amplified electrochemical impedimetric device based on the CISS effect to detect DNA hybridization. Using spin as a detection tool, they achieved a significant amplification of the CISS effect when illuminating the sample with 532 nm light. By observing the spin-dependent asymmetric quenching of photoluminescence, they further confirmed the impact of light on the CISS effect. Based on these findings, they developed a spin-based DNA hybridization sensor with a limit of detection of 10 fM.

Summary: In this study, we investigate the sequence-dependent chiral-induced spin selectivity (CISS) in double-stranded DNA. By using time-correlated single-photon counting and electrochemical impedance spectroscopy, we find that the average lifetime of photo-excited electrons is influenced by the CISS effect generated by the DNA molecule. The observed experimental trends are supported by simulations using a tight binding method.

Summary: This research presents a novel light-amplified electrochemical impedimetric device based on the CISS effect to detect DNA hybridization. By injecting a spin current into the QD-DNA system, a large differential change in charge-transfer resistance (delta R-ct) of around 100 ohms for both spins is observed. With illumination of light at a wavelength of 532 nm, the delta R-ct value increases by nearly threefold to approximately 270 ohms, indicating the amplified CISS effect.

Summary: The thermal instability of silver nanowires leads to increased electrical resistance in AgNW networks. Understanding the relationship between structural and electrical properties of AgNW networks is crucial for their integration as transparent electrodes in flexible optoelectronics. In situ X-ray diffraction measurements were used to study the crystallographic evolution of Ag-specific Bragg peaks during thermal ramping, revealing differences in thermal and structural transitions between bare and SnO2-coated AgNW networks.

Summary: Photodynamic therapy (PDT) is a promising local treatment modality in cancer therapy, but its therapeutic efficacy is restricted by ineffective delivery of photosensitizers and tumor hypoxia. In this study, a phototactic Chlorella-based near-infrared (NIR) driven green affording-oxygen microrobot system was developed for enhanced PDT. The system exhibited desirable phototaxis and continuous oxygen generation, leading to the inhibition of tumor growth in mice. This study demonstrates the potential of using a light-driven green affording-oxygen microrobot to enhance photodynamic therapy.
