Marine science technology innovation provides power and guarantees for marine eco-civilization construction,which provides direction and material support for marine science technology innovation.Therefore,the coordinated development of the two is of great significance to the marine economy sustainable development in China’s coastal areas.On the basis of clarifying the connotations of marine science technology innovation and marine eco-civilization in China’s coastal areas from 2006 to 2019,the mechanism for their coordinated development was analysed.A comprehensive indicator system based on the connotation of the two was constructed,and the coordinated development relationship was empirically tested using the coupled coordination model and the panel vector autoregressive(PVAR)model.The results show that:1)the level of China’s coastal marine science technology innovation continues to improve,gradually forming the core of the development of marine science technology innovation in the north,east and south of Shandong,Shanghai and Guangdong;the level of marine eco-civilization development fluctuating upward trend,showing obvious spatial differentiation characteristics.2)The degree of coordination of marine science technology innovation and marine eco-civilization is growing over time.There is no causal relationship between marine science technology innovation and marine eco-civilization in the northern marine economic circle,but there is a two-way causal relationship between the two in the eastern and southern marine economic circles.3)Marine eco-civilization shows a significant positive and continuous impact on marine science technology innovation,and marine science technology innovation shows a long-term,continuous,fluctuating,and lagging impact on marine eco-civilization.The overall role of marine eco-civilization on marine science technology innovation is dominant,and there are significant differences in the impact effects of the two major marine economic circles.

The development of host-guest MOF luminescent composites has attracted considerable attention. However,it is still a challenge to reasonably design large scale conjugated polycarboxylic acids metal-organic framework (MOF) and modulate donor-acceptor interaction. Herein,a series of isostructural 3D porous lanthanide MOF [Ln_(2)(BINDI)0.5(NO_(3))(DMA)(H_(2)O)]∙DMA∙2.5H_(2)O (Ln = La (1),Ce (2),Pr (3) and Nd (4);H_(4)BINDI (N,N’-bis(5-isophthalic acid)-1,4,5,8-naphthalenediimide) were synthesized. Considering the electron-deficient performances of Ln-BINDI MOFs,D-A type composites Ln-MOFs (1—4@H_(4)TBAPy) were prepared via the incorporation of electron-rich H_(4)TBAPy (1,3,6,8-tetrakis(p-benzoic acid) pyrene),which more improved the luminescence performance of complexes 1—4 and can be used as fluorescence sensors for the detection of nitro compounds and aldehydes. High sensitivity of 1@H_(4)TBAPy towards pNBA,pNA PNP,DNP,and TNP could be achieved through hydrogen bond interactions between MOF and analytes,as well as the π-π interaction between H_(4)TBAPy and the naphthalene ring of BINDI,thus the fluorescence quenching efficiency of 1@H_(4)TBAPy was better than that of the complex 1. In addition,it is found that 1@H_(4)TBAPy has high selectivity and sensitivity to aromatic aldehyde SA,5-Mesal and HMBA. Such strategy to enhance the emission of NDI based Ln-BINDI MOFs,will open up an avenue to obtain more fluorescent MOFs for sensing.

A Class of m-Complex Symmetric Operators on Hardy Space

引用

Journal of Mathematical Research with Applications 2024年第1期44卷 63-80页

作者： Jia FU Xinmei LI Ran LI School of Mathematics Liaoning Normal University

In this paper,we study the necessary and sufficient condition that the Toeplitz operators with respect to the conjugations of one permutation are 2-complex symmetric.Firstly,we introduce a class of conjugations called the conjugations of one permutations on the classical Hardy space.Secondly,Toeplitz operators are completely characterized as 2-complex symmetric structure under this class of conjugations.The matrix representation of Toeplitz operators in the classical regular orthogonal basis on Hardy space is used to describe this class of 2-complex symmetric Toeplitz operators.Finally,we add two preconditions fn=-f-nand fn=f-nrespectively to the Toeplitz operators,and we get more simplified results.Under the second condition,we study the 3-complex symmetry of Toeplitz operators,and we get the same result for Tfis a 3-CSO with the conjugation C((i,j)) and 2-CSO’s.

Harnessing overlapped temperature-salinity gradient in solar-driven interfacial seawater evaporation for efficient steam and electricity generation

引用

Journal of Energy Chemistry 2024年第8期95卷 694-700页

作者： Peida Li Dongtong He Jingchang Sun Jieshan Qiu Zhiyu Wang State Key Lab of Fine Chemicals Liaoning Key Lab for Energy Materials and Chemical Engineering Dalian University of Technology School of Physics and Electronic Technology Liaoning Normal University College of Chemical Engineering Beijing University of Chemical Technology

Solar-driven interfacial water evaporation（SIWE） offers a superb way to leverage concentrated solar heat to minimize energy dissipation during seawater desalination. It also engenders overlapped temperaturesalinity gradient（TSG） between water-air interface and adjacent seawater, affording opportunities of harnessing electricity. However, the efficiency of conventional SIWE technologies is limited by significant challenges, including salt passivation to hinder evaporation and difficulties in exploiting overlapped TSG simultaneously. Herein, we report self-sustaining hybrid SIWE for not only sustainable seawater desalination but also efficient electricity generation from TSG. It enables spontaneous circulation of salt flux upon seawater evaporation, inducing a self-cleaning evaporative interface without salt passivation for stable steam generation. Meanwhile, this design enables spatial separation and simultaneous utilization of overlapped TSG to enhance electricity generation. These benefits render a remarkable efficiency of90.8% in solar energy utilization, manifesting in co-generation of solar steam at a fast rate of 2.01 kg m-2-h-1and electricity power of 1.91 W m-2with high voltage. Directly interfacing the hybrid SIWE with seawater electrolyzer constructs a system for water-electricity-hydrogen co-generation without external electricity supply. It produces hydrogen at a rapid rate of 1.29 L h-1m-2and freshwater with 22 times lower Na+concentration than the World Health Organization（WHO） threshold.

This study aims to revise the Belief in a Just World Scale(BJWS)for Chinese college students and test its reliability and validity(construct validity,convergent and divergent validity).Two samples of 546 and 595 college students were selected,respectively,using stratified cluster random sampling.Item analysis,exploratory factor analysis(EFA),confirmatory factor analysis(CFA),reliability analysis and convergent and divergent validity tests were carried out.The results showed that the 13 items of the BJWS have good item discrimination.The corrected item–total correlation in the general belief in a just world subscale was found to range from 0.464 to 0.655,and that in the personal belief in a just world subscale was 0.553 to 0.715.The internal consistency coefficients of the revised version of the BJWS and its subscales are good.The EFA and CFA results show that the structure and items of the revised scale are the same as those of the original scale.Belief in a just world was found to have significant positive correlations with gratitude and empathy,and has a significant negative correlation with anxiety,thereby exhibiting good convergent and divergent validity.Therefore,the Chinese revised version of the BJWS has good reliability and validity.

Chinese Physics C 2024年第6期 5-8页

作者：李春花王希俊吴晨 Department of Physics and Electronic Technology Liaoning Normal University Center for Theoretical and Experimental High Energy Physics Liaoning Normal University

Particle χc0（3915） was first observed by the Belle experiment in the ωJ/ψ invariant mass spectrum in the process B→KωJ/ψ and subsequently confirmed by the BaBar experiment.Both experiments reported the resonant parameters of this particle in the processes γγ→ωJ/ψ and B→KωJ/ψ assuming χc0（3915） as an S-wave Breit-Wigner resonance.We performed a global fit to the distributions of invariant mass of ωJ/ψ measured by the Belle and BaBar experiments and additionally incorporated the measurements reported by the LHCb experiment to extract the mass and width of χc0（3915）.We obtained M=3920.9±0.9 MeV/c2and Γ=18.2±2.4 MeV,which are consistent with the values from PDG within one standard deviation but with higher precision.

Coniopteris simplex is a common component in many Jurassic floras.However,due to morphological variations in sterile fronds and incomplete preservation of reproductive organs,its classification has been controversial for a long time.Here,we present new material collected from the Middle Jurassic Yan’an Formation in the Ordos Basin,Inner Mongolia.The new material reveals important morphological characters,including hemi-dimorphic fronds,two forms of sterile pinnae,short-stalked sori and sporangia on fertile fronds,annulus of sporangium composed of about 30 cells,in situ rounded triangular spores with protruded suture,and the lips of trilete laesura encircled by one or two rows of small ostioles.Based on these observations,we emended the diagnosis of this common species.The spatio-temporal distribution of Coniopteris simplex shows that the iconic species was restricted to the paleolatitudes ranging from 19.5°N to 48.9°N in the Northern Hemisphere during the Early—Late Jurassic,mainly distributed in the tropical to paratropical zones,and the paleolongitude ranging from 9.6°E to 129.3°E,which may be limited by the opening of the Viking Corridor and the splitting of the Central Atlantic Ocean.
