Summary: The spontaneous crystallization method was used to synthesize two non-centrosymmetric scandium borate crystal materials with wide band gaps and good second harmonic generation (SHG) effects. First-principles calculations revealed that the arrangement of [B5O10](5-) groups and the distortion of ScO6 polyhedra were responsible for the SHG response. The materials may have potential applications in UV nonlinear optical devices.

Summary: Despite decades of efforts, accurately designing and synthesizing second-order nonlinear optical (NLO) crystals remains a challenge. KBe2BO3F2 (KBBF) is the only NLO material capable of generating deep ultraviolet light through direct second-harmonic generation, making it an ideal structural template for designing environmentally friendly candidates based on reported compounds. This review focuses on the accurate design and synthesis of high-performance NLO materials from a microscopic crystal structure perspective, aiming to provide insights into efficient and rapid design and synthesis of targeted compounds. Additionally, a new concept called the quality factor is proposed to comprehensively evaluate the overall performance of new ultraviolet NLO materials, considering requirements such as second-harmonic generation, cut-off edge, and birefringence. This concept enables a direct and convenient assessment of the practical NLO output capability of ultraviolet NLO materials.

Summary: In this study, two quaternary diamond-like semiconductors in the Cu-Zn-Ge-Se system, Cu2ZnGeSe4 and the new Cu4ZnGe2Se7, were compared in terms of their crystal structures, electronic structures, and physicochemical properties. The compounds exhibit different optical bandgaps and SHG responses, with Cu2ZnGeSe4 showing a larger SHG coefficient compared to benchmark materials. Both compounds are air and thermally stable, undergo phase transitions, and have wide windows of optical clarity.

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: This study investigated the influence of hydrothermal synthesis conditions on nanocrystalline particles with a phase of variable composition. The BFWO phase structural parameters were found to be affected by the chemical composition, while the average crystallite size and aggregate size changed with different hydrothermal synthesis conditions. Furthermore, the Eg value was shown to decrease with an enrichment of BFWO composition in Bi and Fe, and a decrease in the volume fraction of crystallites in the surface layer of aggregates.

Summary: This investigation examines the differences in fluorescence behavior of dyes with various nitro substituents. The presence of the NO2 group significantly enhances fluorescence intensity at 298 K. Methylene green (MG) exhibits a non-radiative process where the excitation energy migrates to triplet states, resulting in absence or low fluorescence compared to methylene blue (MB). However, at liquid nitrogen temperature, MG shows significantly higher fluorescence and phosphorescence in ethanol. Similarly, MB exhibits a six-fold increase in fluorescence intensity at 77 K in ethanol. The study reveals different lifetimes in the excited state for each dye in various solvents. Additionally, MG exhibits phosphorescence at 780 nm in ethanol and at 810 nm in chloroform.

Summary: The local structure of Rh-CeO2 catalysts prepared by the co-precipitation method was investigated, and highly dispersed Rh3+ single ions and RhOx clusters were found. The substitution of Ce4+ ions by Rh3+ species led to a distortion of the CeO2 lattice. The presence of single Rh3+ sites and cluster rhodium species had a positive effect on the catalytic activity of the samples in low-temperature CO oxidation.

Summary: In this study, colloidal Au, Pd, and Au-Pd catalysts prepared by pulsed laser ablation in liquid were investigated for 5-hydroxymethylfurfural (HMF) oxidation. The Au1_yPdy alloy nanoparticles formed stable structures in pure water without the use of surfactants, and exhibited higher catalytic performance towards formylfuran carboxylic and furandicarboxylic acids compared to monometallic samples. These results indicate the synergistic effect of the Au-Pd interface in the alloy nanoparticles, where the metals activate different moieties of the HMF molecule in aerobic catalytic HMF oxidation.

Summary: Novel yttrium-doped CeO2, MnOx, and CeMnOx composites are investigated as catalysts for low-temperature NH3-SCR. The study found that undoped CeMnOx mixed oxide exhibits significantly higher deNO(x) performance compared with undoped and Y-doped MnOx and CeO2 catalysts. The presence of yttrium in CeMnOx lowers the catalyst activity by promoting the competitive NH3-SCO reaction and reducing the amount of NH3 available for NO reduction. The study also analyzed the physical-chemical properties of the prepared catalysts using various techniques.

Summary: Magneto-mechanical microsurgery (MMM) with magnetic nanodisks modified with cancer-recognizing molecules is a promising method for radical tumor resection at a single-cell level. The use of low-frequency alternating magnetic fields (AMF) allows for remote control and effective destruction of tumor cells. By characterizing and applying magnetic nanodisks with a three-layer structure (Au/Ni/Au) and DNA aptamer AS42 (AS42-MNDs) on the surface, MMM has shown significant reduction in tumor cells.

Summary: Na3R(BO3)(2) (R = La-Gd) borates crystallize in the space group P2(1)/n with the peaks in the 980(La)-950(Gd) degrees C range attributed to phase transition process and the melting process occurring at a higher temperature.

The thermal expansion tensor components and unit-cell parameters of Na3Nd(BO3)(2) were defined, and the photoluminescence properties of doped Na3Gd(BO3)(2) borates were studied.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. 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.
