Development of sustainable and efficient recycling technology for spent Li-ion batteries: Traditional and transformation go hand in hand

Clean and efficient recycling of spent lithium-ion batteries(LIBs)has become an urgent need to promote sustainable and rapid development of human society.Therefore,we provide a critical and comprehensive overview of the various technologies for recycling spent LIBs,starting with lithium-ion power batteries.Recent research on raw material collection,metallurgical recovery,separation and purification is highlighted,particularly in terms of all aspects of economic efficiency,energy consumption,technology transformation and policy management.Mechanisms and pathways for transformative full-component recovery of spent LIBs are explored,revealing a clean and efficient closed-loop recovery mechanism.Optimization methods are proposed for future recycling technologies,with a focus on how future research directions can be industrialized.Ultimately,based on life-cycle assessment,the challenges of future recycling are revealed from the LIBs supply chain and stability of the supply chain of the new energy battery industry to provide an outlook on clean and efficient short process recycling technologies.This work is designed to support the sustainable development of the new energy power industry,to help meet the needs of global decarbonization strategies and to respond to the major needs of industrialized recycling.

Healthy function and high valued utilization of edible fungi

Edible fungi are large fungi with high added value that can be utilized as resources.They are rich in high-quality protein,carbohydrate,various vitamins,mineral elements and other nutrients,and are characterized by high protein,low sugar,low fat and low cholesterol.In addition,edible fungi contain a variety of bioactive substances,such as polysaccharides,dietary fiber,steroids,polyphenols,and most of these compounds have antioxidant,anti-tumor and other physiological functions.This review comprehensively discusses the bioactive components and functional characteristics of edible fungi(such as antioxidant,anti-aging,hypolipidemic activities,etc.).Then the recent developments and prospect in the high-valued utilization of edible fungi are discussed and summarized.The objective of this review is to improve the understanding of health-promoting properties of edible fungi,and provide reference for the industrial production of edible fungi-based health products.

CALCULATION OF FUZZY RELIABILITY IN THE CASE OF RANDOM STRESS AND FUZZY FATIGUE STRENGTH

The fuzzy sets theory is introduced into the fatigue reliability analysis. The concepts of maximizing set and minimizing set are developed to decide the ordering value of each fuzzy number, and these values can be used to determine the order of the fuzzy numbers. On the basis of the works mentioned above, the membership function defining the fuzzy safety event can be calculated, and then the fuzzy reliability in the case of stress and fuzzy fatigue strength is deduced. An example is given to illustrate the method.

Strength Acquisition Mechanism of High Temperature Resistant Materials Prepared by Waste Architectural Ceramics

In order to realize the large-scale and high-value utilization of waste architectural ceramics,high-temperature resistant materials based on waste architectural ceramics were prepared with sodium silicate as the binder,clay/bauxite and metakaolin/bauxite as coating materials,and the cold strength obtaining mechanism was explored.The phase composition,the microstructure and the mechanical properties of the high temperature resistant materials based on waste architectural ceramics were tested and analyzed.The results showed that when the heat treatment temperature was between 110-1000℃,the strength of the samples mainly came from the physical adhesion of sodium silicate and fine powder.When the temperature rose to 1100℃,the strength of the sample was improved since the internal low-melting-point components melted and promoted sintering.The addition of clay and bauxite can effectively enhance the flexural strength of the samples when the heat treatment temperature is 1000℃.When the heat treatment temperature rises from 900 to 1000℃,the flexural strength of the samples will be enhanced owing to the formation of silica alumina spinel and mullite from metakaolin.

Investigation and Analysis of Grassland Plant Germplasm in Zhalantun City of Eastern Inner Mongolia

The plant germplasm resources of Zhalantun grassland in the eastern Inner Mongolia were investigated in 2015.The order of plant biomass production in all the types of grassland decreased compared to 1985 as the followings:mountain meadow(76.72%)>temperate meadow steppe(66.53%)>lowland meadow(55.03%)>temperate typical steppe(26.37%).There were 243 plant species belonging to 166 genera and 47 families in Zhalantun grassland,including 163 forage species,78 medicinal species and 82 ornamental plant species attributable to 103 genera of 33 families,65 genera of 29 families and 63 genera of 29 families,respectively.In addition,38 species of edible plants,29 species of toxic and harmful plants and five rare protected plants were found in this area.

Commodity layout in supermarkets:using the integration of the comprehensive related value method and genetic algorithm

The existing shelf layout methods do not explicitly consider the attention and relevancy of the commodity systematically and thus have failed to capture the invalid associations,resulting in poor sales impact and customer satisfaction.For such shortcomings,in this paper,we propose a mathematical programming approach for shelf layout problems based on comprehensive related value.First,we introduce the concepts of related value considering both attention and relevancy;second,we give the concept of adjacent utility value and the freedom of placement,and further analyze the impact of the same commodity on surrounding commodities due to different placement positions;third,we establish a new comprehensive related value-based commodity layout optimization model(CRV-CL)and provide the solution steps integrating with a genetic algorithm.Finally,we analyze the characteristics of CRV-CL through a specific case.The simulation results indicate the overall relevancy after applying the CRV-CL model.

The End of Western Economic Growth Theory

Economics is a science that studies how the economy grows,so the theory of economic growth is the most important theory of economics.In the real market economy society,people achieve the goal of economic growth through two kinds of economic activities:production and transaction.Then a correct economic growth theory must be one that can explain both production and transaction economic activities.Just like Newton’s law of universal gravitation in physics,it can explain the motion law of all objects.For a long time,we have been dominated by the western economic growth theory of western mainstream economics.It is not difficult to find that it has a fatal defect,which can only explain production economic activities but not transaction economic activities.So it can’t explain the Chinese economy,and it can’t explain the western economy.The new economic growth theory proposed in this paper makes up for the defects of western economic growth theory,and it is the terminator of western economic growth theory.This is a revolution of new economics to traditional western economics.
