Vector soliton and noise-like pulse generation using a Ti3C2 MXene material in Research

Shuai Wang, Lei Li, Yu-feng Song, Ding-yuan Tang, De-yuan Shen, Lu-ming Zhao,sdulilei@gmail.com,lmzhao@ieee.org

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 3,   Pages 287-436 doi: 10.1631/FITEE.2000033

Abstract: We built a Tm:Ho co-doped fiber laser using a TiC material as a saturable absorber (SA). The formation of s (VSs) and s (NLPs) was observed. The SA was prepared by dripping a TiC solution on a side-polished D-shaped fiber and then naturally vaporized. The VS is characterized by two coexisting sets of Kelly sidebands. By modulating the polarization controller in the fiber laser, NLPs with about 3.3 nm bandwidth can be switched from the VS. To the best of our knowledge, this is the first time that VSs have been generated in a fiber laser using a TiC material as the SA.

Effective regeneration of thermally deactivated commercial V-W-Ti catalysts

Xuesong SHANG, Jianrong LI, Xiaowei YU, Jinsheng CHEN, Chi HE

Frontiers of Chemical Science and Engineering 2012, Volume 6, Issue 1,   Pages 38-46 doi: 10.1007/s11705-011-1167-z

Abstract: An effective method for the regeneration of thermally deactivated commercial monolith SCR catalysts was investigated. Two types of regenerated solutions, namely NH Cl (1 mol/L) and dilute H SO (0.5 mol/L), were employed to treat the used catalyst. The effects of temperature and the regeneration process on the structural and textural properties of the catalysts were determined by X-ray diffraction, scanning electron microscopy, N adsorption/desorption, elemental analysis and Fourier transform infrared spectroscopy. The results suggest that the anatase phase of the used catalyst is maintained after exposure to high temperatures. Some of the catalytic activity was restored after regeneration. The catalyst regenerated by aqueous NH Cl had a higher activity than that of the catalyst treated by dilute H SO . The main reason is that the NH generated from the decomposition of NH Cl at high temperatures can be adsorbed onto the catalyst which promotes the reaction. The aggregated V O were partially re-dispersed during the regeneration process, and the intrinsic oxidation of ammonia with high concentrations of O is a factor that suppresses the catalytic activity.
