文摘Organic solvent nanofiltration(OSN) is an efficient,low-energy and environmentally friendly phase-free separation process.Obviously,the core of OSN lies in the fabrication of solvent-resistant nanofiltration membranes.Although membrane materials reported in the literature such as 2D membranes,porous organic cages,etc.have the potential for ultra-high performance,polymeric membranes provide key advantages in mass production and processability.Therefore,this review focuses on polymeric materials for OSN.This review summarizes the recent progress of polymeric materials,including emerging and traditional polymeric membranes.Then,a summary of recent progress about strategies developed for perm-selective nanofilms are presented,followed by a brief overview of commercial membrane technology for OSN.Finally,major challenges of OSN and future research directions are presented.Close interaction between the academic research and practical application would help improve greener and more sustainable manufacturing processes.
文摘In order to improve the competitiveness of smart tourist attractions in the tourism market,this paper selects a scenic spot in Shenyang and uses big data technology to predict the passenger flow of the scenic spot.Firstly,this paper introduces the big data-driven forecast model of scenic spot passenger flow.Based on the traditional autoregressive integral moving average model and artificial neural network model,it builds a big data analysis and forecast model.Through the analysis of data source,model building,scenic spot passenger flow accuracy,and modeling time comparison,it affirms the advantages of big data analysis in forecasting scenic spot passenger flow.Finally,it puts forward four commercial operation optimization strategies:adjusting the ticket pricing of scenic spots,upgrading the catering and accommodation services in scenic spots,planning and designing play projects,and formulating accurate scenic spot marketing strategies,in order to provide references for the optimization and upgrading of smart tourist attractions in the future.

文摘This study aims to examine the challenges and future directions of large-scale wooden construction education at universities in Japan and Finland.It compares the wooden construction curricula at universities and the architectural education initiatives undertaken by firms specializing in large-scale wood construction design in both countries.The target applications for large-scale wooden construction are residential,commercial,and public buildings.Comparing university education revealed many commonalities between the two countries,allowing them to be classified into two types:“seminar-centered”and“lecture-centered”.Japanese universities are categorized by building type and scale for educational purposes.Finnish universities focus their education on the properties and functions of wood.Based on these results,we infer that incorporating both Japan’s architecture-planning-focused education and Finland’s materials-focused education into teaching,using familiar housing buildings as a theme,will lead to the wider adoption of large-scale wooden construction.
