Summary: This study investigates the structural, electrical and transport properties of cobalt nanoferrites (CoFe2O4) doped with dysprosium cation (Dy3+) on the iron (Fe3+) site. The results confirm that the samples maintain a pure cubic spinel structure. The average crystallite size ranges from 49 to 72 nm and is not affected by the concentration of Dy3+ ions. The lattice parameters vary from 8.34 Å for pristine CoFe2O4 to 8.39 Å for the sample with the highest doping concentration (Dy(x) = 0.15). The porosity decreases with increasing Dy3+ ion concentration. The electrical properties are analyzed through dielectric behavior at different frequencies and temperatures. The ferrite with Dy(x) = 0.15 exhibits the highest dielectric constant in the range of 441 to 5234, indicating its suitability for memory storage devices.

Summary: The effects of La3+ and Al3+ substitution on the structural, dielectric, and piezo-electric properties of (1-x)(K0.5Bi0.5)TiO3-xLaAlO3 ceramics were investigated. With the increase in LAO content, a decrement in tetragonal distortion and an increase in cubic symmetry were observed. The incorporation of LAO in KBT resulted in an improved relaxor behavior and a suppression of oxygen vacancies. The piezo-electric properties were enhanced, with the 3% LAO-doped sample exhibiting the highest piezo-electric charge coefficient and improved piezo-electric voltage coefficient. An energy harvesting experiment was performed on the poled 3% LAO-doped ceramic, showing promising results under normal finger tapping.

Summary: We investigated the effects of Cu doping on the structure, morphology, magnetic properties, cytotoxicity, and biocompatibility of ZnO nanostructures. Our results show that the incorporation of Cu2+ ions inhibits the growth of nanorods and leads to the disappearance of nanorod morphology at higher doping levels. X-ray photoelectron spectroscopy confirms that Cu ions substitute Zn2+ sites in their divalent state. Magnetic measurements reveal a significant change in the magnetic features due to doping. Cytotoxicity assessment demonstrates that Cu-doped ZnO samples are non-toxic. Our findings suggest the potential usefulness of Cu doping in spintronic/magnetic media devices and as a promising approach for new functional biomaterials in biomedical applications.

Summary: Chinese banks have emerged as the dominant cross-border creditors for a significant number of emerging market and developing economies (EMDEs). Despite similarities in ownership and balance-sheet structure to other EMDE banks, their global cross-border lending patterns are more akin to those of banks from advanced economies, particularly when lending to EMDEs. Our research demonstrates that geographic distance poses a hindrance to cross-border lending, including for Chinese banks. However, this barrier is relatively lower for Chinese banks due to their extensive network of affiliated institutions, similar to US or European banks. Moreover, we find a positive correlation between cross-border lending and bilateral economic activities such as trade, foreign direct investment (FDI), and portfolio investment across all bank nationalities. What sets Chinese banks apart is that their lending to EMDEs shows a stronger correlation with trade compared to any other nationality, while there is no such correlation with FDI. Furthermore, unlike other banks, Chinese banks' lending exhibits a negative correlation with portfolio investment.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
