However, the presence of defects and ion migration in MHPs results in high and unstable dark currents, which compromise the stability and detection performance of MHP-based optoelectronic devices. Interfacial engineering has proven to be an effective strategy to reduce defect density in MHPs and suppress ion migration. Given the compatibility of silicon (Si) and MHP processing technologies, coupled with the simplicity and cost-effectiveness of the approach, the integration of MHPs onto Si surfaces has become a prominent area of research. This integration not only enhances device performance but also expands their practical applications. This review provides an overview of the integration technologies for Si and single crys-tal MHPs, evaluates the advantages and limitations of various integration schemes (including inverse temperature crystallization, vacuum-assisted vapor deposition, and anti-solvent vapor-assisted crystallization), and explores the practical applications of Si/MHP-integrated optoelectronic devices with different structures. These optimized devices exhibit outstanding performance in X-ray detection, multi-wavelength photodetection, and circularly polarized light detection. This review provides a systematic reference for technological innovation and application expansion of Si/MHP-integrated devices.展开更多

Moreover, methods and tech-nologies employed in different urbanization SEA hierarchies are summarized. As a case study, urbanization SEA-ITS is applied in Changchun City to solving complex real problems. Methods such as system dynamics and grey cluster are adopted to achieve the environmental impact assessment on the eco-industrial system planning. It is revealed that the system designed is capable of reflecting the dynamic behavior of eco-industrial system under different sce-narios, meanwhile accomplishing strategy optimization and supplying scientific reference. The 4th strategy, namely concerning on economy increase and its interaction with science, technology and environment progress, would have the best efficiency.

However, at the systematic level, the comprehensive utilization of different energy resources in an energy system has become an issue of concern. In this work, a systematic approach is proposed, one that successively integrates heat, work and adjusts operation parameters. A detailed procedure for building a heat-work coupling transfer network is provided. The synthesis mainly consists of constructing a work exchange sub-network with pinch analysis based on positive displacement type work exchangers. Simultaneously, another kind of sub-network based on turbine-type work exchangers is built as a schematic comparison. The influence of applying a positive displacement work exchanger on the system is investigated. Finally, as a case study, a renovation design of a typical rectisol process in the coal-water slurry gasification section of an ammonia plant is presented. The results show that the added work exchanger has little impact on the existing heat exchange sub-network. Moreover,extra pressure energy is recovered by coupling the transfer network. It is concluded that the heat-work systematic design is a promising and powerful method to use energy more efficiently.展开更多
