Two methods of natural ecosystem assessment—emergy analysis (EMA) and life cycle assessment (LCA)—are reviewed in this paper. Their advantages, disadvantages, and application areas are summarized, and the similarities and differences between these two evaluation methods are analyzed respectively. Their research progress is also sorted out. The study finds that EMA and LCA share common attributes in evaluation processes and research fields, but they focus on different aspects of macrocosms and microcosms. The assessment of system sustainability is valued by both EMA and LCA, but the former has unique advantages in natural system input analysis, and the latter is more convincing in assessing environmental loading capacity. If the system boundaries of the two methods are expanded, in other words, factors such as ecosystem services, labor, and infrastructure construction are integrated into the upstream of the target system, and environmental impact is further analyzed using LCA in the downstream of the system, the two approaches would complete each other. The quantified results would be more objective. Therefore, these two theories have the necessity of coupling development. After reviewing recent coupling application cases, the results show that LCA and EMA have commonality in the upstream of the target system (mainly in inventory database construction), while the environmental impact assessment methods are different in the downstream. So the overall coupling analysis method is not formed. The current paper gives rational suggestions on the coupling development of the two systems in terms of the aggregate emergy flow table, the indicator system construction and indicator evaluation methods. In addition, it is necessary to introduce sensitivity analysis and uncertainty analysis in order to improve the reliability of assessment results. At present, the research on the coupling development of the two theories is in rapid development stage, but there are still many problems that need further exploration.

With the wide application of various functional materials, corrosion problems have not only caused huge losses in economy but also made a waste of energy and resources. Superhydrophobic surface treatment technology, which is a new anticorrosion technology, can inhibit the corrosion of various functional materials effectively. This paper reviews the advances in research on superhydrophobic surface, introduces the basic theory of superhydrophobic surface, summarizes the preparation method of super hydrophobic surface and the existing problems, and introduces the latest research progress of functional superhydrophobic materials.

Background: Superhydrophobic surfaces have unique wettability and have shown broad application prospects in many fields, such as self-cleaning and lubrication drag reduction. However, the superhydrophobic surfaces are severely restricted by their poor mechanical stability in practical application, and the mechanical stability of the superhydrophobic surface is always affected by different preparation methods. Therefore, people pay more attention to the preparation methods of superhydrophobic surfaces. Objective: The study aims to improve the mechanical stability of the superhydrophobic surface and expand the application fields of the superhydrophobic surfaces; preparation methods of the superhydrophobic surface have been continuously improved. Methods: This paper reviews various representative patents and papers on preparation methods of the superhydrophobic surface at home and abroad. Results: In this review, the basic methods of preparing superhydrophobic surfaces were introduced, and three typical methods were summarized, such as etching method, coating method, and sol-gel method, then their advantages and disadvantages were discussed. In combination with the latest research progress, it is proposed that the use of environmentally friendly low surface energy modifiers and the use of the one-step method to prepare superhydrophobic surfaces are the future development trends. Aiming at the problem of the mechanical stability of superhydrophobic surfaces, the instability mechanism and stability evaluation methods of superhydrophobic surfaces under mechanical action are reviewed, and three basic methods to improve the mechanical stability of superhydrophobic surfaces are proposed. Conclusion: The optimization of the preparation method of the superhydrophobic surface is beneficial to improve the mechanical stability of the superhydrophobic surface and expand the application prospect of the superhydrophobic surfaces in various fields. More patents and papers on the superhydrophobic surface will be invented later.

Bonding agents are an important type of additive that are used to increase the interfacial interaction in propellants. A suitable bonding agent can prevent the dewetting between the oxidant and binder, and thus effectively improve the mechanical properties of the propellant. In the current paper, the bonding mechanisms and research progress of different types of bonding agents such as alcohol amine bonding agents, borate ester bonding agents, aziridine bonding agents, hydantoin bonding agents, neutral polymer bonding agents, and so on, are reviewed and discussed. The evaluation methods of their bonding performances including molecular dynamic simulation, contact angle method, in situ loading SEM, characterization analysis, and mechanical analysis are summarized to provide design ideas and reference for future studies.
