Summary: This study focuses on the effect of varying degrees of undercooling on the microstructure development of the Fe50Cu50 alloy system. Different undercooling conditions were achieved using the aerodynamic levitation (ADL) technique. The results showed that a complete phase separation occurred in the substantially undercooled sample, while a discontinuous network of Cu was found in the inter-connected Fe dendritic areas in other situations. X-ray diffraction confirmed that the final phases were alpha-Fe and Cu regardless of the degree of undercooling.

Summary: Light-based therapies and diagnoses, such as photodynamic therapy (PDT), have been widely used in various fields of medicine. PDT requires a light source and a light-sensitive compound to detect and destroy cancer cells. However, one of the challenges is the depth of light penetration into biological tissues.

Summary: Compared to Cu(In,Ga)Se-2 devices, the current efficiency of CZTSSe solar cells is still low due to carriers recombination within interface and absorber bulk. This study pioneers the construction of synergistic passivation effects (SPE) to simultaneously address the bulk and interface recombination issue. By introducing a niobium pentoxide passivation layer into the back electrode interface (BEI), SPE is achieved through diffusion of Nb (& O) from Nb2O5 layer to absorber bulk and BEI at high-temperature selenization. The chemical passivation effect is fulfilled via the high resistance characteristic of Nb2O5 layer, and through NbOx passivation in the absorber bulk. Meanwhile, the occupations of Nb (& O) induce a conduction type inversion in MoSe2 interfacial layer, creating a favorable p(+)-Mo(Se,O)(2):Nb/CZTSSe interface and achieving an interfacial field passivation effect. Ultimately, the improved absorber quality and charge carrier transportation from SPE contribute to device performance beyond 10% efficiency.

Summary: Perovskite solar cells have shown remarkable progress in photovoltaic performance and have gained attention as an alternative to traditional silicon solar cells. The application of upconversion materials in PSCs can enhance spectral absorbance and energy conversion efficiency, but challenges such as high-threshold power and low energy transfer efficiency remain obstacles for their widespread use.

Summary: Rare earth elements (REEs), including Scandium (Sc), are essential raw materials for modern technologies and efforts are being made to explore their procurement from secondary resources with sustainability and circular economy principles. Electrodialysis (ED) technology has been successfully utilized for separating and concentrating REEs from diluted aqueous systems, showing promising results in recovering Sc3+ ions from wastewater with high efficiency and low energy consumption. Systematic assessments using various parameters confirmed the effectiveness of ED process in removing Sc3+ ions, indicating its potential for practical applications in resource recovery.

Summary: Large anti-Stokes lasing can be achieved through multi-photon upconversion processes using rare earth elements. This study demonstrates the four- and five-photon upconversion lasing from rare earth elements under continuous-wave pump and room temperature conditions for the first time. The microlaser exhibits low thresholds and good stability of lasing intensity for practical applications, providing a prospect for high-performance short-wavelength lasers.

Summary: The structural, thermal, and electrical properties of (La0.2Nd0.2Sm0.2Gd0.2Eu0.2)1-xCaxNbO4-δ (x = 0-0.05) series were studied. X-ray powder diffraction and thermogravimetry were used to determine the structural and thermal characteristics, while electrochemical impedance spectroscopy was employed to measure the electrical properties. The results showed that the materials had stable crystal structures and the addition of calcium dopant significantly enhanced the conductivity.
