The Bayesian structural equation model integrates the principles of Bayesian statistics, providing a more flexible and comprehensive modeling framework. In exploring complex relationships between variables, handling uncertainty, and dealing with missing data, the Bayesian structural equation model demonstrates unique advantages. Therefore, Bayesian methods are used in this paper to establish a structural equation model of innovative talent cognition, with the measurement of college students’ cognition of innovative talent being studied. An in-depth analysis is conducted on the effects of innovative self-efficacy, social resources, innovative personality traits, and school education, aiming to explore the factors influencing college students’ innovative talent. The results indicate that innovative self-efficacy plays a key role in perception, social resources are significantly positively correlated with the perception of innovative talents, innovative personality tendencies and school education are positively correlated with the perception of innovative talents, but the impact is not significant.

Developing high-performing non-noble transition metal catalysts for H_(2) evolution from chemical hydrogen storage materials is of great significance for the hydrogen economy system, yet challenging. Herein,we present for the first time that anomalous metastable hexagonal close-packed Ni nanoparticles induced by heteroatom N doping encapsulated in carbon(N-hcp-Ni/C) can exhibit admirable catalytic performance for ammonia borane(AB) dehydrogenation, prominently outperforming conventional fcc Ni counterpart with similar morphology and favorably presenting the state-of-the-art level.Comprehensive experimental and theoretical studies unravel that unusual hcp phase engineering of Ni together with N doping could induce charge redistribution and modulate electronic structure, thereby facilitating H_(2)O adsorption and expediting H_(2)O dissociation(rate-determining step). As a result, AB dehydrogenation can be substantially boosted with the assistance of N-hcp-Ni/C. Our proposed strategy highlights that unconventional crystal phase engineering coupled with non-metal heteroatom doping is a promising avenue to construct advanced transition metal catalysts for future renewable energy technologies.

Spirolindemers A and B,unprecedented lindenane sesquiterpenoid dimer(1)and trimer(2)equipped with oxaspiro[4.5]decane unit,were discovered from the medicinal plant Chloranthus henryi.Their structures including absolute configurations were achieved by HRMS,NMR,ECD,X-ray diffraction analyses,and quantum chemical calculations.Biogenetically,hetero-and homo-Diels-Alder additions may dominate the formation of oxaspiro[4.5]decane and spiro[4.5]decane skeletons,respectively.Compound 1 showed anti-inflammatory activity by inhibiting the expression of iNOS and COX-2.

Hippophae rhamnoides ssp.sinensis(Rha)and H.tibetana(Tib)are two species of sea buckthorn which distribute in Qinghai-Tibet Plateau.Our results showed that both sea buckthorn leaf exhibited high total phenolic and flavonoid content,and Rha leaf showed much higher level.In addition,66 phenolic compounds were detected,belonging to classes of benzoic acid derivatives,flavonols,flavanols,flavanones,and so on.Classes of benzoic acid derivatives and flavonols were most abundant,among them ellagic acid and rutin were the most and second abundant phenols.Besides,methyl gallate,2,6-dihydroxybenzoic acid,4-hydroxybenzoic acid,gentisic acid,narcissin,astragalin,nicotiflorin,prunin,procyanidin B3,cyanidin 3-O-rutinoside chloride,delphinidin 3-glucoside,gallocatechin,taxifolin,aromadendrin and trans-3,3′,4′,5,5′,7-Hexahydroxyflavanone were the first time to be identified in SBT leaf.Furthermore,significant free radical scavenging effects of ABTS and DPPH,ferric reducing antioxidant ability,cellular antioxidant properties and anti-proliferation activity against HepG2 cells were observed in the aqueous ethanol extracts of sea buckthorn leaf.While Rha showed stronger inhibitory effects,which might due to the higher content of total phenolic and flavonoid profiles.Our finding clearly supported that Rha leaf as a wild and non-pollution plant could be a better choice as a healthy food resource.

Guided by MS/MS molecular networks strategy,chlospicenes A and B(1 and 2),the first example of cyclopropane moiety cracked lindenane sesquiterpene Michael addition dimers,along with their biogenetic analogues(3 and 4),were targetedly discovered from the roots of Chloranthus henryi.Their structures including absolute configurations were characterized by NMR,ECD and X-ray diffraction analysis.The plausible biogenic pathway speculation indicated that cyclopropylcarbinyl rearrangement may dominate the key crack of cyclopropane moiety.In addition,compounds 1 and 2 showed significant anti-nonalcoholic steatohepatitis(NASH)activity in free fatty acid(FFA)-induced HepG2 cells by decreasing intracellular lipid accumulation.

Sarcaglarols A-D(1-4),two pairs of lindenane-monoterpene heterodimers fused by a 1,2-dioxane moiety,were discovered and isolated from the leaves of Sarcandra glabra guided by MS/MS molecular networking-based strategy.Their planar structures,absolute configurations of basic skeleton and flexible polyhydric side chain were established by analysis of HRESIMS,NMR spectroscopic data,ECD spectrum,and the X-ray diffraction study of isopropylidene derivatives.An intermolecular[2+2+2]cycloaddition may play a key role in the biosynthesis pathway of the 1,2-dioxane moiety fused lindenane-monoterpene heterodimer skeleton,which can be recognized as the biogenetic precursors of our previous reported lindenane-normonoterpene conjugates.In addition,compounds 1,3 and 4 exhibited moderate inhibitory effects of lipid accumulation in free fatty acid-exposed L02 cells.
