The regulation of electric-optical properties of polymer-dispersed liquid crystals via implantation of polyhedral oligomeric silsesquioxane (POSS) microstructure

Zemin He, Ping Yu, Yuzhen Zhao, Qing Yang, Yang Zhao, Huimin Zhang, Shuai Zi, Zongcheng Miao, Haiquan Zhang, Wenbo Shen

Summary: Improving the electro-optical performance of polymer-dispersed liquid crystal (PDLC) films was achieved by implanting polyhedral oligomeric silsesquioxane (POSS) microstructure into the polymer matrix. The size of polymer meshes increased with the content of POSS microstructure, leading to higher static water contact angles. The anchoring effect of the polymer matrix containing POSS microstructure was weakened, resulting in a dramatic regulation effect on the electro-optical properties of the PDLC films.

Cooperative Enhancement of Second Harmonic Generation in an Organic-Inorganic Hybrid Antimony Halide

Fafa Wu, Qingyin Wei, Xiaoqi Li, Yi Liu, Weiqi Huang, Qin Chen, Bingxuan Li, Junhua Luo, Xitao Liu

Summary: Exploration of nonlinear optical crystalline materials is a hot topic in the field of modern optoelectronics and laser technology. The study focuses on the emerging organic-inorganic hybrid metal halides, which have the potential to provide infinite opportunities. In this study, a non-centrosymmetric organic-inorganic hybrid antimony halide was developed by combining an inorganic second-order Jahn-Teller distorted octahedron with an organic pi-conjugated aromatic amine. The crystals showed a remarkable second harmonic generation response and moderate birefringence, indicating their potential for applications in the field of nonlinear optics. The crystal structure analysis and theoretical calculations revealed that the large second harmonic generation response is primarily due to the cooperative coupling between the highly asymmetric distorted octahedron and the pi-conjugated aromatic amine.

Synergism of 1D CdS/2D Modified Ti3C2Tx MXene Heterojunctions for Boosted Photocatalytic Hydrogen Production

Shi Cheng, Qianqian Xiong, Chengxiao Zhao, Xiaofei Yang

Summary: This study reports an integrated CdS nanorod/oxygen-terminated Ti3C2Tx MXene nanosheet heterojunction with high catalytic hydrogen evolution reaction (HER) activity. The heterojunction achieved a hydrogen-evolving rate much higher than bulk CdS and CdS/unmodified MXene hybrid catalysts. The enhanced HER activity and stability are attributed to the presence of oxygen-containing terminal groups, extended light absorption spectra, and the precisely constructed intimate Schottky contact.

Recent Advances in Fabricating Wurtzite AlN Film on (0001)-Plane Sapphire Substrate

Hualong Wu, Kang Zhang, Chenguang He, Longfei He, Qiao Wang, Wei Zhao, Zhitao Chen

Summary: Ultrawide bandgap (UWBG) semiconductor materials have attracted great attention recently, and wurtzite aluminum nitride (AlN) is a typical representative with many advantages. However, due to the lack of low-cost, large-size, and high-ultraviolet-transparency native AlN substrate, heteroepitaxial AlN film grown on sapphire substrate is usually used. This review summarizes the recent advances in fabricating wurtzite AlN film on sapphire substrate, discussing control principles of AlN polarity, ways to control threading dislocations and strain, achieving high thermal conductivities, and future challenges.
