Summary: GPO is a non-traditional UV NLO phosphate material with wide UV transparency, strong SHG response, and sufficient optical birefringence, making it suitable for phase-matching at short SHG wavelengths. Due to the introduction of pi-conjugated cations and their favorable arrangement with anions, GPO shows promising potential as a UV solar-blind NLO material that simultaneously optimizes wide UV transparency, large SHG response, and optical anisotropy.

Summary: This study investigates a new scheme for evaluating the temperature dependence and dispersion relation of the Kerr constant in optically isotropic medium in isotropic and blue phases liquid crystals. The scheme overcomes the problem of a nonuniform electric field and allows for direct measurement of the Kerr constant. It is found that the dispersion relation can be described by a simple linear form in the isotropic phase and an inverse exponential form in the blue phases.

Summary: By enhancing the anisotropy microstructure of Ga(2)Se(3) with stereochemically active lone-pair electrons from Pb2+, a phase-matchable nonlinear optical crystal, PbGa4Se7, has been designed and synthesized. PbGa4Se7 exhibits a significantly higher second-harmonic generation (SHG) coefficient and laser-induced damage threshold compared to AgGaS2 due to its low anisotropy of thermal expansion coefficient and suitable optical band gap. The enhanced phase-matchable SHG response of PbGa4Se7 arises from the synergies of tetrahedral GaSe4 and pyramid PbSe3 microstructural blocks.

Summary: Multifunctional materials are of great interest in research. Organic-inorganic hybrid perovskites are commonly used in designing these materials due to their versatile properties and adaptable composition. By introducing chiral groups as ligands, it becomes easier to enhance the photoelectric properties. In this study, chiral one-dimensional organic-inorganic hybrid perovskites, namely (R/S-3-HP)PbBr3 (1R/1S) (3-HP=3-hydroxy-piperidine), were synthesized, exhibiting reversible phase transition at 349/336 K. Excited by light at 339 nm, 1R and 1S emitted orange light with a broad peak at 635 nm. Additionally, they possessed an indirect bandgap of 3.29 eV and SHG intensity comparable to KDP. This work offers a new approach to the design of multifunctional chiral perovskite materials.

Summary: This study demonstrates a strongly correlated two-dimensional excitonic insulator ground state in transition metal dichalcogenide semiconductor double layers, providing direct thermodynamic evidence for the state. Capacitance measurements show that the exciton fluid is compressible but charge-incompressible. An exciton phase diagram reveals both the Mott transition and interaction-stabilized quasi-condensation.

This study investigates the properties and light response of these materials. The results show that some azobenzene PAAD materials are suitable for forming surface relief gratings with high modulation depth, while others exhibit strong photoinduced birefringence. The diffraction caused by the induced diffraction gratings is quantified using analytical formulas and numerical simulations.

Summary: PbZr1-xTixO3 perovskite materials, also known as PZT, exhibit highly applicable piezoelectric properties. Recent research has demonstrated the potential of PZT in piezoelectric response by optimizing crystal growth technology. The coexistence of phases with different symmetries and dense domain walls are the primary sources of their high piezoelectric response, while strong electric fields can lead to the disappearance of piezoelectric activity.

Summary: A series of ZnO/SiO2 adsorbents was prepared using a sol-gel method, and the impact of gel drying temperature on their structure and desulfurization performance was investigated. It was found that low drying temperature resulted in weak interactions in the gel system, leading to oxidation of ethylene glycol (EG) and the formation of zinc glyoxylate complex. The formation of this complex hindered the desulfurization performance of the adsorbents. On the other hand, drying the gel at 120 degrees C improved the interactions in the gel system and resulted in the formation of ZnO nanoparticles with a size of 6 nm, leading to a higher sulfur capacity of 104.9 mg center dot g (-1).

Summary: Seven novel inherently nanolaminated transition metal carbides with R in-plane chemical ordering in the carbide sheet have been synthesized and crystallized in Cmcm orthorhombic structure. The Vickers hardness of these compounds is significantly higher than that of Cr2AlC benchmark, resulting in higher compressive fracture strength and better wear resistance. The compression at high temperature reveals the nanoscale co-existence of monoclinic and orthorhombic structures, which is caused by random stackings and high-density slidings within ab plane.

Summary: Regulating the crystal structure through A-site cation substitution is an effective method for exploring high-performance nonlinear optical materials. In this study, two non-centrosymmetric compounds, alpha-LiZnPO4 and alpha-KZnPO4, were obtained by A-site cation substitution, with short UV absorption edges at 221 and 225 nm, respectively. It is noteworthy that alpha-LZPO achieved more than 10 times second harmonic generation (SHG) enhancement compared to alpha-KZPO, which is the only case among phosphates with different A-site cations. Structural analysis and theoretical calculations were conducted to understand the role of A-site cations in anion rearrangements and the structural features of the two compounds. This study confirms the feasibility of designing promising NLO materials with enhanced SHG response and structural stability in the orthophosphate system.
