A BBO-like trithiocyanate with significantly enhanced birefringence and second-harmonic generation
Science China Materials - Tập 66 - Trang 3271-3277 - 2023

There is presently a great demand for nonlinear optical (NLO) crystals that can demonstrate both strong second-harmonic generation (SHG) and high birefringence in emerging spin-orbit angular momentum photonic technologies. Here we report a new chiral trithiocyanate compound, K4(HC3N3S3)2·H2O, which is composed of highly π-conjugated [HC3N3S3]2− rings and is structurally analogous to commercial NLO... hiện toàn bộ

Prussian blue assembled on graphene oxide for enhanced capacitive deionization and water disinfection
Science China Materials - - Trang 1-10 - 2023
Nan Li, Panyu Ren, Miao Tian, Ke Wang, Atif Saleem, Nian Liu, Luofeng Yu, Peng Li
Capacitive deionization (CDI) with water disinfection materials is an energy-efficient technology for the simultaneous desalination and bio-decontamination of brackish water. However, desalination capacity is always limited by the mechanism of ion electrosorption within the electrical double layer. Recently, the water disinfection ability of CDI has been demonstrated through the functionalization ... hiện toàn bộ
Engineering membrane electrode assembly for advanced polymer electrolyte water electrolyzer
Science China Materials - Tập 65 - Trang 3243-3272 - 2022
Heming Liu, Xin Kang, Taifeng Zhao, Zhiyuan Zhang, Shiyu Ge, Shuqi Hu, Yuting Luo, Fengning Yang, Shao-Hai Li, Chenghua Sun, Qiangmin Yu, Hui-Ming Cheng, Bilu Liu
As an important energy carrier in terms of carbon neutrality, green hydrogen produced by water electrolysis using renewable electricity has attracted worldwide attention. The polymer electrolyte water electrolyzer (PEWE) has the potential to be a mainstay in the green hydrogen market in the future because of its superior performance. However, the development of PEWE is constrained by the slow prog... hiện toàn bộ

Bioactive small-molecule-based aqueous zinc-organic battery enables long-life and fast-charge performance
Science China Materials - Tập 66 - Trang 3104-3112 - 2023
Meng Zhang, Chaojian Ding, Chaobo Li, Yonghui Wang, Weiwei Huang
Aqueous zinc-ion batteries (AZIBs) have become a current research hotspot owing to their high security and cost-effectiveness. However, the dissolution of electrode materials, low intrinsic conductivity, and slow reaction kinetics seriously hinder their practical application. Herein, a sulfur-containing organic small molecule (seriniquinone, SQ), which plays a significant role in melanoma treatmen... hiện toàn bộ
Ag4Hg(SeO3)2(SeO4): a novel SHG material created in mixed valent selenium oxides by in situ synthesis
Science China Materials - Tập 62 - Trang 1821-1830 - 2019
Xiao-Xue Wang, Xiao-Bao Li, Chun-Li Hu, Fang Kong, Jiang-Gao Mao
Explorations of new second harmonic generation materials in Ag+-Hg2+/Bi3+-selenites systems afforded three new silver selenium oxides, namely, Ag4Hg(SeO3)2(SeO4) (1), Ag2Bi2(SeO3)3(SeO4) (2) and Ag5Bi(SeO3)4 (3). They exhibit flexible crystal chemistry. Compounds 1 and 2 are mixed valence selenium oxides containing Se(IV) and Se(VI) cations simultaneously. Compounds 1 and 3 exhibit a 3D open frame... hiện toàn bộ
Self-reduction synthesis of supported ultrafine Pd nanoparticles with high activity and stability in hydrogenation
Science China Materials - Tập 66 - Trang 2708-2714 - 2023
Shiguang Mo, Wentong Jing, Weijie Zhang, Kunlong Liu, Binghui Wu, Ruixuan Qin, Nanfeng Zheng
Supported ultrafine metal nanoparticles display outstanding catalytic performance in heterogeneous catalysis. Nevertheless, there are limited convenient and practical approaches for synthesizing supported ultrafine metal nanoparticle catalysts, despite the development of advanced fabrication methods. High-temperature reduction is often required for the preparation of metal catalysts for catalytic ... hiện toàn bộ
