| 1 | Enhanced Photocatalytic Activity of Bi_(24)O_(31)Br_(10): Constructing Heterojunction with BiOI显示文摘Bismuth-based compounds have been regarded as an important class of visible-light photocatalysts due to their special electronic structures. In this paper, iodide ions are introduced to modify bismuth-based compound, Bi_(24)O_(31)Br_(10), forming a Bi_(24)O_(31)Br_(10)/BiOI heterojunction structure. A significant enhancement of photocatalytic activity compared to the parent compounds is observed in de-coloration of rhodamine B(Rh.B) solution. The improved photocatalytic property of Bi_(24)O_(31)Br_(10)/BiOI heterojunction is ascribed to the unique electronic structure consisting of complementary band structures of BiOI and Bi_(24)O_(31)Br_(10).Iodide ions are regarded as an effective reagent to construct bismuth-based photocatalytic heterojunctions with improved photocatalytic activity. | Xi Lou Jun Shang Liang Wang Haifeng Feng Weichang Hao Tianmin Wang Yi Du | 2017 | Journal of Materials Science & Technology2017，33，3： | 3 |
| 2 | Distributed Model Predictive Control with Actuator Saturation for Markovian Jump Linear System显示文摘This paper is concerned with the distributed model predictive control(MPC) problem for a class of discrete-time Markovian jump linear systems(MJLSs) subject to actuator saturation and polytopic uncertainty in system matrices. The global system is decomposed into several subsystems which coordinate with each other. A set of distributed controllers is designed by solving a min-max optimization problem in terms of the solutions of linear matrix inequalities(LMIs). An iterative algorithm is developed to achieve the online computation. Finally,a simulation example is employed to show the effectiveness of the proposed algorithm. | Yan Song Haifeng Lou Shuai Liu | 2015 | IEEE/CAA Journal of Automatica Sinica2015，2，4： | 2 |
| 3 | Rice SPL10 positively regulates trichome development through expression of HL6 and auxin-related genes显示文摘Trichomes function in plant defenses against biotic and abiotic stresses;examination of glabrous lines,which lack trichomes,has revealed key aspects of trichome development and function.Tests of allelism in 51 glabrous rice(Oryza sativa)accessions collected worldwide identified OsSPL10 and OsWOX3B as regulators of trichome development in rice.Here,we report that OsSPL10 acts as a transcriptional regulator controlling trichome development.Haplotype and transient expression analyses revealed that variation in the approximately 700-bp OsSPL10 promoter region is the primary cause of the glabrous phenotype in the indica cultivar WD-17993.Disruption of OsSPL10 by genome editing decreased leaf trichome density and length in the NIL-HL6 background.Plants with genotype OsSPL10^(WD-17993)/HL6 generated by crossing WD-17993 with NIL-HL6 also had fewer trichomes in the glumes.HAIRY LEAF6(HL6)encodes another transcription factor that regulates trichome initiation and elongation,and OsSPL10 directly binds to the HL6 promoter to regulate its expression.Moreover,the transcript levels of auxin-related genes,such as OsYUCCA5 and OsPIN-FORMED1b,were altered in OsSPL10 overexpression and RNAi transgenic lines.Feeding tests using locusts(Locusta migratoria)demonstrated that non-glandular trichomes affect feeding by this herbivore.Our findings provide a molecular framework for trichome development and an ecological perspective on trichome functions. | Jinjie Li Bo Tang Yingxiu Li Chenguang Li Minjie Guo Haiyang Chen Shichen Han Jin Li Qijin Lou Wenqiang Sun Peng Wang Haifeng Guo Wei Ye Zhanying Zhang Hongliang Zhang Sibin Yu Long Zhang Zichao Li | 2021 | Journal of Integrative Plant Biology2021，63，8： | 2 |
| 4 | Species Composition and Diversity of Macrobenthos in the Intertidal Zone of Xiangshan Bay,China显示文摘Xiangshan bay is a narrow semi-closed bay and situated on the northwestern coast of the East China Sea. Over past decades, it has become to a major bay with intensive human activities, dense urbanized area, and poor water quality. The aim of this paper was to reveal the ecological status through the elucidation of the species composition, abundance, biomass and diversity of macrobenthos in this bay. Six intertidal sections were surveyed from January 2007 to November 2008 quarterly. Sections TG, HD and XH are located in the three inner bays, sections QJ and WS are located near the thermal power plants, and section XX is located at the outer part of Xiangshan Bay. Great variations in macrobenthos community were indentified, and the species composition of the community in the present study showed the dominance in the order of molluscs(bivalves and gastropods), crustaceans and others, and only few Polychaeta were recorded. Only three dominant species, Littorina brevicula, Ilyplax tansuiensis, and Cerithidea cingulata were collected in all the sections, and a total of 19 dominant species were recorded only in one section. Two-way ANOVA analyses of abundance indicated that there were significant differences among sections or seasons. Shannon-Wiener diversity index(H') had its maximum(2.45) in section QJ, and minimum(1.76) in section TG. Multiple irregular k-dominance plots clearly showed that the study area was polluted and the macrobenthos community was under stress. We conclude that the macrobenthos of Xiangshan Bay have been disturbed by human activities, especially at the interior bay. | JIAO Haifeng ZHENG Dan YOU Zhongjie XU Nianjun LOU Dan HUANG Chengwei | 2015 | Journal of Ocean University of China2015，14，2： | 1 |

| 6 | IFE based nanosensor composed of UCNPs and Fe(Ⅱ)-phenanthroline for detection of hypochlorous acid and periodic acid显示文摘Oxidizing CIO^(-)and IO_(4)^(-)exist widely in environment and are closely related to the health of organisms.Accordingly,fast,sensitive,and direct detection of the two species is significant.Using IFE in UCNPs@PAA and Fe(Ⅱ)-phenanthroline system,an elegant ratiometric fluorescent nanosensor,without noble metal nanoparticle,was designed for the detection of CIO-and IO4-.Fe(Ⅱ)-phenanthroline complex is used as fluorescent absorber,which can quench green light of UCNPs with gradually varied extent depending on the concentration of Fe(Ⅱ).The linear zone extends to 800 and 120μmol/L while the detection limit is 1.30 and 0.58μmol/L for NaCIO and NaIO_(4),respectively.Finally,the nanosensor was successfully applied to detect NaCIO and NaIO4spiked in milk,spring water,and tap water with good recoveries. | Haining Song Haifeng Zhou Qianqian Zhuang Zexin Li Fenglei Sun Zhenlei Yuan Youxin Lou Guangjun Zhou Yujun Zhao | 2023 | Journal of Rare Earths2023，41，2： | 0 |
