Summary: Nonlinear optical response is a useful tool for studying the properties of materials, but its weak signal and limited reach make it difficult to probe deep-subwavelength-scale nonlinear optics. In this study, we propose a new method using an SHG-active plasmonic nanotip to achieve efficient second harmonic generation (SHG) nanoscopy. Our simulations suggest that enhancing the nonlinear response of the sample or suppressing the tip's response can lead to a high near-field SHG contrast, providing evidence of quantum mechanical nonlinear energy transfer. Furthermore, this technique can be used to study nanoscale corrosion and other physicochemical phenomena.

Summary: This paper presents the synthesis, crystal structure, and characterization of several new noncentrosymmetric rare-earth borates of the gaudefroyite family Sr2MBi(REEO)3(BO3)4 (M = Ca, Sr, Ba; REE = Y, Eu). Sr2MBi (YO)3(BO3)4 (M = Ca, Sr, Ba) borates were synthesized through multi-step solid state reactions. The crystal structures of Sr3Bi(YO)3(BO3)4, Sr2CaBi(YO)3(BO3)4, and Sr2BaBi(YO)3(BO3)4 were refined and their thermal expansion coefficients were calculated. Second-harmonic generation measurements showed an increase in the nonlinear optical activity of the materials when Sr was partially substituted with Ca and Ba, and a decrease when Y atoms were replaced by Eu.

Summary: Metasurfaces have shown great potential in optical wave manipulation but face challenges in multidimensional manipulation of harmonic waves generated by nonlinear metasurfaces. This study presents an efficient design strategy based on the hydrodynamic model of free electron dynamics, allowing for full complex-amplitude modulation of second harmonic generation. The proposed nonlinear metasurfaces demonstrate spin-selective SHG optical vortices with independent topological charges, opening up new possibilities for nonlinear metasurface applications in optical information and multifunctional integration.

Summary: Second harmonic dipoles generated in a nonlinear photonic crystal slab can be completely nonradiative, resulting in no energy transfer from the fundamental frequency to the second harmonic even when the phase-matching condition is satisfied - a phenomenon known as resonance-forbidden second-harmonic generation. Through numerical simulation, two mechanisms for achieving this phenomenon have been identified: symmetry protection and parameter tuning. The finite-size effect and the topological origin of this phenomenon are also discussed.

Summary: We present a theoretical study on second-harmonic generation from a singular metasurface, which strongly interacts with incident light and generates intense surface polarization, resulting in the generation of second-harmonic field. By using transformation optics, the calculation of nonlinear optical response is simplified, and the dependence on the incident angle is weak, making it potentially useful for all-angle harmonic generation. Furthermore, we investigate the symmetry dependence of second-harmonic generation in the far field and demonstrate an enhanced conversion efficiency under normal incidence by breaking the surface inversion symmetry.

Summary: Engineering nonlinear optical processes in dielectric nanostructures using chalcogenide phase-change material allows for efficient tuning of second-harmonic generation processes. The nonlinear SHG signal from nanoantennas can be enhanced and modulated by optically induced Mie-type resonances and the amorphous-to-crystalline phase change in GST. By adjusting the refractive index of GST, a maximum modulation depth of up to 540% is demonstrated, showing the potential for control of optical nonlinearity and smart designing of tunable nonlinear optical devices.

Summary: We present a frequency-domain modeling technique for second-order nonlinear metasurfaces, derived from the generalized sheet transition conditions (GSTCs). By extending the GSTCs to include effective nonlinear polarizations, the effective nonlinear susceptibilities of a given metasurface can be retrieved and its nonlinear scattering responses can be predicted under arbitrary illumination conditions. The proposed model can serve as a design platform for implementing complex nonlinear metasurface based applications.

Summary: We synthesized and characterized the solid solutions Cu3Bi(Se(1-x)TexO(3))(2)O2Br (x = 0, 0.25, 0.5, 0.75, 1) for the first time. The interlayer antiferromagnetic (AFM) coupling in francisites was found to be due to interlayer high-spin orbital interaction across the van der Waals (vdW) gaps rather than interlayer spin exchange. We proposed a method to modify francisites to create oxide vdW ferromagnets.

Summary: Developing multielectron redox-active cathode materials is crucial for achieving high energy density and long cycle life in next-generation secondary battery applications. Triggering anion redox activity is a promising strategy to enhance the energy density of polyanionic cathodes for Li/Na-ion batteries. In this study, K2Fe(C2O4)2 is identified as a promising cathode material that combines metal redox activity with oxalate anion (C2O42-) redox. It exhibits specific discharge capacities of 116 and 60 mAh g-1 for sodium-ion batteries (NIB) and lithium-ion batteries (LIB) cathode applications, respectively, at a rate of 10 mA g-1, with excellent cycling stability. The experimental results are supported by density functional theory (DFT) calculations of the average atomic charges.

Summary: A new family of compounds with the formula ACu(7)TeO(4)(SO4)(5)Cl (A=Na, K, Rb, Cs) isostructural to mineral Nabokoite (K species) was synthesized and characterized. These compounds exhibit interesting properties as quasi-two-dimensional magnets with a square kagome lattice geometry. The presence of wavy and distorted triangles in the lattice, along with additional magnetic ions, adds complexity to the magnetism of these compounds. The interaction of the magnetic ions through virtual excitations of the lattice leads to the coexistence of long-range magnetic order and spin liquid behavior.

Summary: A new family of layered quinary compounds, SrLn4(TeO3)4Cl6, with monoclinic structures (P2/c), have been obtained by the interaction of LnOCl and TeO2 (Ln = Ce, Nd, Sm) in molten SrCl2. The structures are characterized by the alternation of [M2Ln3(TeO3)4] layers (M = Ln0.5Sr0.5) and double halide sheets. The presence of twinning suggests possible stacking disorder and polytypism. Crystal structures belong to the OD (order-disorder) family of category III with one type of nonpolar OD layers, and can be described by the same OD family groupoid. Possible maximal degree order polytypes have been predicted, and crystal chemical relationships among the oxyhalides of rare earth and lone-pair cations are briefly discussed.

Summary: This study reports a new rare-earth selenite mineral, dysprosium francisite, and analyzes its magnetic and thermodynamic properties through optical spectroscopy. The lifting of Kramers degeneracy induced by a magnetic field reveals magnetic ordering at a temperature of 39 K. The single-ion anisotropy of the dysprosium ion dominates the magnetic anisotropy of the copper subsystem. The study also demonstrates low-dimensional magnetism and the interaction between magnetic and charge degrees of freedom, i.e., multiferroicity, in this material near the critical temperature.

Summary: The production possibility of 161Tb and 155Tb via gamma ray irradiation of natural dysprosium decelerated by an electron beam was demonstrated experimentally.

Summary: Monoclinic Cu4O(SeO3)3 was prepared using hydrothermal method and subsequent heating in evacuated silica tubes. The compound exhibits magnetic ordering at T1 = 13.2 K and a pre-transitional anomaly at T2 = 17.2 K. The application of external magnetic field suppresses excessive magnetization of the intermediate phase, but a hump in specific heat is observed. First principles calculations provide values of both ferro-magnetic and antiferromagnetic exchange interactions within O2Cu6 units, as well as anti-ferromagnetic intralayer and interlayer exchange interactions. A magnetic model for monoclinic Cu4O(SeO3)3 is proposed based on the signs and values of these interactions.

Summary: The iron-based polyanionic fluoro-oxalate material, KFe(C2O4)F (KFCF), synthesized by hydrothermal methods, exhibits promising reversible lithium and sodium insertion properties as a cathode material. In lithium-ion and sodium-ion batteries, the material achieved a first-cycle discharge capacity of 120 mAh g(-1) and 97.4 mAh g(-1) at voltages of approximately 3.3 V (Li+/Li) and 3.0 V (Na+/Na) respectively. Stable cycling performance was observed in both cases. The involvement of reversible Fe2+/Fe3+ redox was confirmed through ex-situ Mossbauer spectroscopy and first-principles calculations. This study demonstrates the potential of mixed oxalate-fluoride based polyanionic materials in the development of new electrode materials.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
