An Analysis on the Formation and Cultivation of Environmental Protection Norms in the Context of Green Gamification

Currently, individual green behaviors have attracted great attention from many countries for environmental degradation. It is particularly critical to identify useful strategies to motivate users’ green behaviors. Based on the goal framing theory, this paper considers three target motivations (hedonic goal, gain goal, and normative goal) of users’ behaviors, proposes the formation and cultivation mechanics of green behaviors in the green gamification platform, and builds a model considering the process of users’ engagement. By comparing users’ quality situation (high, general, low), this paper concludes that a lower involvement degree is required by high-quality individuals when forming and cultivating an environmental behavior habit. The result also benefits organizations that apply gamification designs in varieties of ways to engage and steer users like employees or consumers toward targeted goals

DNA Storage: A Promising Large Scale Archival Storage?

Deoxyribonucleic Acid (DNA), with its high density and long durability, is a promising storage medium for long-term archival storage and has attracted much attention. Several studies have verified the feasibility of using DNA for archival storage with a small amount of data. However, the achievable storage capacity of DNA as archival storage has not been comprehensively investigated yet. Theoretically, the DNA storage density is about 1 exabyte/mm3 (109 GB/mm3). However, according to our investigation, DNA storage tube capacity based on the current synthesizing and sequencing technologies is only at hundreds of Gigabytes due to the limitation of multiple bio and technology constraints. This paper identifies and investigates the critical factors affecting the single DNA tube capacity for archival storage. Finally, we suggest several promising directions to overcome the limitations and enhance DNA storage capacity

Coordinated economic dispatch of the primary and secondary heating systems considering the boiler’s supplemental heating

District heating systems have been widely used in large and medium-sized cities. Typical district heating systems consist of the primary heating system (PHS) and the secondary heating system (SHS) operating in isolation. However, the isolated dispatch of the PHS and the SHS has poor adjustability and large losses, resulting in unnecessary operation costs. To address these issues, a coordinated economic dispatching model (CEDM) for the primary and secondary heating systems considering the boiler’s supplemental heating is proposed in this study, which characterized the physical properties of the PHS and the SHS in detail. Considering that the PHS and the SHS are controlled separately without central operators in practice, it is difficult to dispatch them in a centralized method. Thus, the master-slave splitting algorithm is innovatively introduced to solve the CEDM in a decentralized way. Finally, a P6S12 system is utilized to analyze and verify the effectiveness and optimality of the proposed algorithm

Electrolyte Salts and Additives Regulation Enables High Performance Aqueous Zinc Ion Batteries: A Mini Review

Aqueous zinc ion batteries (ZIBs) are regarded as one of the most ideally suited candidates for large-scale energy storage applications owning to their obvious advantages, that is, low cost, high safety, high ionic conductivity, abundant raw material resources, and eco-friendliness. Much effort has been devoted to the exploration of cathode materials design, cathode storage mechanisms, anode protection as well as failure mechanisms, while inadequate attentions are paid on the performance enhancement through modifying the electrolyte salts and additives. Herein, to fulfill a comprehensive aqueous ZIBs research database, a range of recently published electrolyte salts and additives research is reviewed and discussed. Furthermore, the remaining challenges and future directions of electrolytes in aqueous ZIBs are also suggested, which can provide insights to push ZIBs’ commercialization

What Climate-Orientation Fit Do to Passion for Learning, How Could Danmu Help?

Passion for learning is essential for students to perform well. Prior studies show passion can be influenced by the individual or the environment. The usage of danmu can also affect the participants’ passion. However, drawing on the person-environment fit theory, the match between the environmental climate and personal orientation can influence individuals’ passion for learning, which is meaningful but seldom mentioned. Furthermore, which kinds of involvement of danmu will be the better moderation? To answer these questions, we propose a research model, and plan to conduct a 2 (motivational climate: mastery vs. performance) x 3 (use of danmu: no use vs. questions time only vs. all time) experiment. A deep understanding of climate-orientation fit is pivotal to foster and improve students’ passion for learning. Finding an appropriate way to use the danmu is essential for teachers to create a more suited class environment to optimize students’ passion for learnin

Biomass Carbon Materials Contribute Better Alkali-Metal–Selenium Batteries: A Mini-Review

Owing to the sustainability, environmental friendliness, and structural diversity of biomass-derived materials, extensive efforts have been devoted to using them in high-energy rechargeable batteries. Alkali-metal–selenium batteries, one of the high-energy rechargeable batteries with a reasonable cost compared to up-to-date lithium-ion batteries, have also attracted significant attention. Therefore, a timely and comprehensive review of the biomass carbon structures/components to the mechanisms for enhancing alkali-metal–selenium batteries has been systematically introduced. In the end, advantages, challenges, and outlooks are pointed out for the future development of biomass-derived carbon materials in alkali-metal–selenium batteries. This review could help researchers think about using biomass carbon materials to improve battery performance and what other problems should be solved, thereby promoting the application of biomass materials in battery design
