| 1 | An investigation on a novel PDLC film's fabrication and its electro-optical properties显示文摘A polymer dispersed liquid crystal (PDLC) film that has good electro-optical properties is produced by the method of polymerized-induced phase separation. Based on the application foreground, its capability parameters, such as contrast ratio, work voltage, and visual angle, are characterized for the first time by a white light but not a fixed wavelength light. The results show the PDLC film has a low work-voltage of 20 V, more than 150° visual angle, high stability, and long lifetime. The differences between plastic and glass ITO-coated substrates of PDLC films are also studied in this paper. The plastic substrate has better property and will have a wider perspective especially in the portable, tender and folded display devices. Due to adjustable properties of film by electric field, PDLC has the potential application for display device, sensor, switch, grating, and new generation analytical apparatus. | DING HongLiu, ZHAO Ting, CHENG YuXiao, PANG YueHong, XU He, SHI GuoYue & JIN LiTong Chemistry Department of East China Normal University, Shanghai 200062, China | 2007 | Science China Chemistry2007，50，3： | 2 |
| 3 | Binary trinuclear metal-oxo sub-nanomaterials for photocatalytic hydrogen and chlorine production from seawater显示文摘Owing to the need for regenerant and self-reduction problem,the hydrogen performance of sub-nano-sized trinuclear iron-oxo complexes is still far from satisfied with affordability and practicality.Herein,two binary photocatalytic systems based on trinuclear metal-oxo complexes have been first constructed and experimentally confirmed to be competent for seawater hydrogen evolution(715.4and271.9μmol of hydrogen can be found,respectively,after 48h).Notably,chloride ions act as the hole catcher and move into the gas phase in the stable form of chlorine.Similar to heterogeneous structures,homogeneous systemsnot only enhance the hydrogen performance while ensuring the stability of metal-oxo complexes,but also shorten the consumption of photogenerated carriers by dissolved impurities in the seawater.This new attempt of building pluralistic sub-nanometric systems may offer novel design strategies with noble-metal-free catalysts and low-cost candidates for traditional semiconductor materials in enhancing photocatalytic efficiency and performing chlorine evolution from seawater splitting. | Yang Wang Litong Shi Haijun Hu Bingzhi Qian Wei Hou Hui Li Xue Liu Daliang Liu Shuyao Wu Hongwei Huang Xi-Ming Song Yu Zhang Tianyi Ma | 2022 | SusMat2022，2，6： | 0 |
