| 1 | Effects of lanthanum on the growth and essential oil components of lavender under osmotic stress显示文摘The effects of lanthanum on growth, soluble sugar content, essential oil contents and quality were studied in lavender plant(Lavandula Angustifolia Mill, Variety 701) under osmotic stress by means of PEG-6000 solution. The results show that osmotic stress could reduce the growth rate of lavender, and increase the content of SSC(soluble sugar concentration) to some extent. Compared with control group,the contents of essential oil in flowers and leaves respectively increase by 45.6% and 48.3% in the osmotic stress group induced by 15% PEG-6000. However, the presence of lanthanum can make the contents of essential oil in the flowers and leaves of stressed lavender plants enhance by 19.4% and 18.6%, respectively. Under osmotic stress, the relative contents of four kinds of lavender essential oil compositions of camphor, linalool, linalyl acetate and lavandulol acetate in the lavender flowers were successively 22.63%,0.61%,25.46%,7.03%,and 20.17%,0.62%,20.72%,10.80%,respectively in the presence and absence of lanthanum. The contents of all four main components of lavender essential oils meet the requirements of the national standard under osmotic stress in the presence of lanthanum. However, in the absence of lanthanum, the contents of linalyl acetate and lavandulol acetate does not meet the requirements of the national standard under osmotic stress. Moreover, the contents of five components of borneol, camphor,eudesmol, caryophyllene oxide and bicyclic sesquiphellandrene from the essential oil of lavender leaves are 12.89%, 3.84%, 8.76%, 11.30% and 8.10%, respectively. The total content of above five components accounts for 44.89% of the essential oil of the lavender leaves. Particularly, the borneol content in leaf essential oil is up to 12.89%. It is 125.2 times the amount of borneol in the flower essential oil. In conclusion, the suitable concentration of lanthanum can improve the adaptability of lavender plants, and heighten the content and quality of lavender essential oil to some extent under osmotic stress. | Liyun Zhu Linzhen Song Yongsheng Gao Junqing Qian Xiaodong Zhang Sufang Li | 2018 | Journal of Rare Earths2018,36,8: | 5 |

| 3 | Undescribed Meroterpenoids from Hypericum japonicum with Neuroprotective Effects on H_(2)O_(2) Insult SH-SY5Y Cells Targeting Keap1-Nrf2显示文摘Unreported tautomeric/enantiomeric meroterpenoids,(±)-hyperjaponols I—K(1-3),were discovered from Hypericum japonicum.Comprehensive chemical investigations established the absolute characteristics of these stereoisomers.The TS calculation demon-strated that 1a and 2a easily occur enol-keto tautomerism with steady configurations individually.Amongst isolates,1b showed the strongest neuroprotective activity with the concentration at 25μmol/L on H_(2)O_(2) insult SH-SY5Y cells.In vitro molecular biological ex-periments manifested that 1b activated the Keap1-Nrf2-ARE pathway,leading to the promotion of Nrf2 nuclear translocation,down-regulation of the expression level of Keap1,and upregulation of the levels of Nrf2,NQO-1,and HO-1.The results of in silico simulation showed that 1b possessed good binding features with Keap1(5FNQ)via forming multiple typical hydrogen and hydrophobic bonds as well as less fluctuation of RMSD and RMSF during a natural physiological condition. | Linzhen Hu Zhenzhen Wang Zhou Tong Ping Hu Luqi Kong Mengying Luo Xiao-Nian Li Yuexing Zhang Zhiyong Huang Yonghui zhang | 2022 | Chinese Journal of Chemistry2022,40,11: | 1 |

| 5 | Adaptive control of nonlinear systems with severe uncertainties in the input powers显示文摘In this study,we discuss global adaptive stabilization for a class of uncertain nonlinear systems.The input powers of the system are unknown,and the upper bound and the nonzero lower bound are not known in advance.This suggests that the system suffers from severe uncertainties with respect to the input powers when compared with the related literature,which would considerably challenge the control design.The switching-based strategy can compensate for severe system uncertainties,especially new types of uncertainties,including those associated with the input powers.Herein,a switching adaptive controller is successfully designed to ensure that the resulting closed-loop system states are globally bounded and ultimately converge to the origin(the equilibrium point).The proposed controller is extended to the systems with unknown control directions by redefining the involved switching sequences.A simulation example demonstrates the effectiveness of the proposed switching adaptive controller. | Linzhen YU Yungang LIU Yongchao MAN | 2021 | Science China(Information Sciences)2021,64,1: | 0 |

| 7 | Nitrogen-rich carbon nitrogen polymers for enhancing the sorption of uranyl显示文摘Nitrogen enrichment and increased nitrogen content is an effective strategy for enhancing adsorption of uranium by carbon nitride polymers.Herein,we reported the uranium absorption by using a structurally well-defined and nitrogen-rich carbon nitride polymer with C_(3)N_(5) stoichiometry for the first time.In comparison with the adsorption performance of g-C_(3)N_(4) for U(Ⅵ),the conjugation system of the material was increased by connecting the heptazine unit through the azo bridge in the structure of C_(3)N_(5),so that C_(3)N_(5) exhibited several times higher adsorption performance than that of g-C_(3)N_(4).The C_(3)N_(5) has high kinetics for uranyl ions,which can adsorb100 mg/g U(Ⅵ)in only 10 min and reach complete adsorption equilibrium in 60 min;the theoretical maximum adsorption capacity is 207 mg/g,meanwhile,the material exhibits high selectivity.The results of spectral analysis and theoretical calculations indicate that the process of uranyl ion capture by C3N5is a combination of physical and chemical adsorption,and its higher density of electronic states makes the electrostatic binding ability enhanced,which is favorable to the adsorption of uranyl ions by C_(3)N_(5).This work indicates that C_(3)N_(5) has great promise and application in the separation and enrichment of uranyl ions,and also provides a reference for the systematic investigation of the adsorption ability of nitrogenrich carbon nitrogen polymers on uranyl ions. | Zeru Wang Wenhao Li Linzhen Wu Zhuang Wang Yalan Cao Jingkai Cheng Guangyuan Chen Qian Zhao Mei Jiang Zhengguo Chen Lin Zhu Tao Duan | 2022 | Chinese Chemical Letters2022,33,7: | 0 |
| 8 | Dual-Wavelength Spectrum-Shaped Mid-Infrared Pulses and Steering High-Harmonic Generation in Solids显示文摘Mid-infrared(MIR)ultra-short pulses with multiple spectral-band coverage and good freedom in spectral and temporal shaping are desired by broad applications such as steering strong-field ionization,investigating bound-electron dynamics,and minimally invasive tissue ablation.However,the existing methods of light transient generation lack freedom in spectral tuning and require sophisticated apparatus for complicated phase and noise control.Here,with both numerical analysis and experimental demonstration,we report the first attempt,to the best our knowledge,at generating MIR pulses with dual-wavelength spectral shaping and exceptional freedom of tunability in both the lasing wavelength and relative spectral amplitudes,based on a relatively simple and compact apparatus compared to traditional pulse synthesizers.The proof-of-concept demonstration in steering the high-harmonic generation in a polycrystalline ZnSe plate is facilitated by dual-wavelength MIR pulses shaped in both spectral and temporal domains,spanning from 5.6 to 11.4μm,with multi-microjoule pulse energy and hundred-milliwatt average power.Multisets of harmonics corresponding to different fundamental wavelengths are simultaneously generated in the deep ultraviolet region,and both the relative strength of individual harmonics sets and the spectral shapes of harmonics are harnessed with remarkable freedom and flexibility.This work would open new possibilities in exploring femtosecond control of electron dynamics and light–matter interaction in composite molecular systems. | Linzhen He Weizhe Wang Kan Tian Maoxing Xiang Zhongjun Wan Bo Hu Yang Li Han Wu Zi-Yu Chen Fan Yang Houkun Liang | 2023 | Ultrafast Science2023,3,3: | 0 |

| 10 | A Novel Model of Resolving Contention in Optical Burst Switched Networks显示文摘A Novel segmentation and feedback model (SFM) applied to resolve collision has been proposed. The SFM is featured with Burst Segmentation and Prioritized Feedback (BSPF) that are used to provide quality of service (QoS) and realize high throughput and faster switching in the optical burst switched networks. Simulation and performance analyses show that the SFM effectively avoid collision in optical burst switching (OBS). Long delay time of deflection routing and immature technology of wavelength converter and optical buffer are not employed in the SFM. The SFM not only realizes quick switching but also allows preemption for higher priority bursts. | 黄安鹏 Xie Linzhen Li Jingcong Li Zhengbin Xu Anshi | 2004 | High Technology Letters2004,10,4: | 0 |
