Tao Wang, Qiang Yu, Kun Guo, Xinyao Shi, Xuefen Kan, Yijun Xu, Jian Wu, Kai Zhang, Pu Zhou,wujian15203@163.com,kzhang2015@sinano.ac.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 3,   Pages 287-436 doi: 10.1631/FITEE.2000577

Abstract: has the advantage of broadband saturable absorption from the visible to the infrared bands. Herein, the two-dimensional material saturable absorber (SA) of the family was first applied experimentally in a wideband tunable passively Q-switched Yb-doped fiber laser. High-quality crystals were synthesized by the flux zone method. The SA with fewer layers was further prepared via a modified mechanical exfoliation procedure. Meanwhile, stable wavelength-tunable passive Q-switching pulse operation was obtained in a Yb-doped fiber ring cavity based on the SA, where the central wavelength can be continuously tuned from 1040.89 to 1092.85 nm. Results suggest that has wideband saturable absorption properties, and that the tunable pulse laser can provide a convenient and simple source for practical applications.

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 4,   Pages 471-477 doi: 10.1007/s11705-014-1449-3

Abstract: Lithium -MnO ion-sieves were prepared from spinel LiMn O via treatment with nitric acid. The LiMn O was synthesized by a solid state reaction between LiOH·H O and MnO . The effects of the calcination time and temperature on the preparation of the LiMn O precursor and the lithium ion-sieve were investigated. In addition, the Li extraction ratio, the Mn dissolving ratio and the adsorption properties of the lithium ion-sieve were all measured. The lithium ion-sieve had a high exchange capacity and was selective for Li . Specifically, at pH= 13, the ion exchange capacity of Li was 30.9 mg/g in 10 mmol/L LiCl solution and the lithium extraction ratio and manganese dissolving ratio were 95% and 25%, respectively.
