| 5 | All-optical generation,detection,and manipulation of picosecond acoustic pulses in 2D semiconductor/dielectric heterostructures显示文摘Launching,tracking,and controlling picosecond acoustic(PA)pulses are fundamentally important for the construction of ultrafast hypersonic wave sources,ultrafast manipulation of matter,and spatiotemporal imaging of interfaces.Here,we show that GHz PA pulses can be all-optically generated,detected,and manipulated in a 2D layered MoS_(2)∕glass heterostructure using femtosecond laser pump-probe.Based on an interferometric model,PA pulse signals in glass are successfully decoupled from the coexisting temperature and photocarrier relaxation and coherent acoustic phonon(CAP)oscillation signals of MoS_(2)lattice in both time and frequency domains.Under selective interface excitations,temperature-mediated interfacial phonon scatterings can compress PA pulse widths by about 50%.By increasing the pump fluences,anharmonic CAP oscillations of MoS_(2)lattice are initiated.As a result,the increased interatomic distance at the MoS_(2)∕glass interface that reduces interfacial energy couplings can markedly broaden the PA pulse widths by about 150%.Our results open new avenues to obtain controllable PA pulses in 2D semiconductor/dielectric heterostructures with femtosecond laser pump-probe,which will enable many investigations and applications. | WENXIONG XU YUANYUAN LI QIANNAN CUI HE ZHANG CHUANSHENG XIA HAO GUO GUANGQUAN ZHOU JIANHUA CHANG HUI ZHAO JUN WANG ZHONGZE GU CHUNXIANG XU | 2023 | Photonics Research2023，11，12： | 0 |
| 6 | Effect of extracellular polymeric substances on the phosphorus adsorption characteristics of sediment particles显示文摘Extracellular polymeric substances(EPS) have a great impact on the characteristics of sediment particles and their environmental effects in hydro-environmental systems, yet little effort has been made to study the considerable variability in the element adsorption process of sediment particles caused by EPS.Understanding the variability of the adsorption characteristics of sediment particles associated with EPS and quantifying the scale of the adsorption isotherm parameters are important for understanding how EPS mediate sediment properties and environmental factors. In this paper, isothermal equilibrium adsorption experiments are done on phosphorus to study the influence of EPS on the adsorption characteristics of sediment particles, and the Langmuir adsorption isotherm is applied to analyze the adsorption rule of sediment particles under the impact of EPS. The current research demonstrates that significant differences will take place in the adsorption characteristics of sediments coated with EPS at different development phases and the phosphorus adsorption capacity of sediment particles increases with the growth of EPS. The difference in the adsorption percentage between sediment particles coated with EPS of 0 and 6 weeks growth time is about 42%e60% for different initial aqueous phosphorus concentration. A formula describing the adsorption isotherm parameter of the maximum material(element) adsorption capacity of sediment particles change over time is further proposed based on the experimental data. The current study provides some evidence for the interaction of sediment particles,EPS, and adsorbed elements in the water environment. | Huiming Zhao Yuefeng Zhang Liqun Tang Zhenghui Cui Bing Liu Wei Cheng Chuansheng Guo Dabin Liu Xiaowei Gao Haochuan Feng | 2021 | International Journal of Sediment Research2021，36，5： | 0 |
