As a matter of fact, in recent years, the environmental issues are becoming more and more critical due to the huge pollution especially the emission and energy consumption caused by aircraft engines contributes to the problem. Thus, as two major types of engines, the jet engines and marine engines should be improved as they are the most commonly used aircraft engines. In this article, the diversity of some types of jet engines are introduced, and few modifications in the aspect of structure, power system and fuel are briefly talked about. The passage concluded some problems to overcome and actions that may be conducted in the future. At the same time, in another area that is close to jet engines, the engine design of modern large civilian ships (i.e., marine engines) mainly focusing on efficiency, environmental protection, and reliability. However, civilian ships pay special attention to reducing fuel consumption and environmental pollution, which has prompted the application of various advanced technologies.

Over the past decades, the academic community has devoted considerable attention to mesoporous and microporous materials, primarily due to their distinctive nanoscale pore structures. Despite the extensive research conducted on these materials, there is still a pressing need to develop methods for optimizing their synthesis and improving their performance. Therefore, this paper introduces the basic concepts of mesoporous and microporous materials and their importance, and describes in detail their typical synthesis methods that include the solution-gel method for the synthesis of mesoporous materials and the ionothermal synthesis method for the synthesis of microporous materials. The paper then goes on to examine some of the more common characterization methods that are used in the field, such as X-ray diffraction (XRD), nitrogen adsorption, and transmission electron microscopy (TEM), and also lists some of the ways in which these characterization methods have been used in the context of electrochemical capacitors and photocatalytic explanation. It has been shown that mesoporous and microporous materials have the potential for significant applications in energy storage and environmental remediation. Further research should concentrate on the improvement of the synthesis process and the investigation of additional application areas, with the aim of fully exploiting the potential of these materials.

The soft lithography enables the fabrication of microfluidic honeycombs, which are micron-scale, orthogonally aligned hexagonal mesoporous silica (HMS) patterns with channels embedded within them, on silicon substrates. The process entails meticulous cleaning, precise master mold design (including features for channel alignment) using electron-beam lithography, generation of polydimethylsiloxane (PDMS) mold creation, ink formulation, and pattern transfer. Subsequent steps include the sol-gel transition, hardening, alignment verification, characterization, and optional functionalization. It is of the utmost importance to optimize these steps and the master design in order to achieve success. Therefore, the paper examines the creation of micron-scale HMS patterns with orthogonal alignment through the innovative application of soft lithography. The technique encompasses the strategic design of hexagonal motifs, precision master mold crafting, the PDMS stamps, and a meticulous sol-gel procedure, resulting in HMS structures that exhibit remarkable precision and adaptability. This paper underscores the transformative potential of soft lithography in the realm of advanced materials, which offers a controlled and uniform approach to size and uniformity. The refined soft lithography process not only achieves the precise orthogonal alignment of HMS patterns but also highlights its adaptability and economic viability in nanotechnology ventures.

Taking the integration of modern information technology and green building as the research background, we study the current status of BIM technology and green building development and application in the existing green building evaluation standard system, analyze the obstacles existing in the practical application of BIM technology in the whole life cycle of green building under the new global evaluation standard, and point out the direction of further research. The results of the study show that at this stage, BIM technology and green building-related regulations and systems are not yet sound, the evaluation standard system is not yet perfect, and there is a lack of organic synergy between each other,"Siloing" at certain points throughout the life cycle of a building. Green buildings are far away from the development and application of BIM technology and green buildings. The phenomenon of "isolated" in some stages of the whole life cycle of the building, some links appear as an "island" phenomenon, there is still a gap between green building and comprehensive coverage, and the widespread application of BIM technology needs to be promoted. In the future, the application research on sustainable development of green buildings based on BIM should be committed to further improve the relevant regulations, systems, and evaluation standards, create a core database of all relevant information in each stage of the whole life cycle of the building, realize the interactive sharing of information, implement the BIM integrated application mode, give full play to the advantages of the whole life cycle and integrated management of BIM, and integrate BIM technology with green building in a deeper way.

Three-dimensional integrated circuits have higher integration than two-dimensional integrated circuits, and can obtain higher performance and lower power consumption in a certain space. In order to fulfill higher efficiency, thermal management becomes particularly important in 3D integration technology. However, the traditional heat dissipation method cannot satisfy the heat dissipation needs of three-dimensional integrated circuits, which require better heat dissipation methods to be developed.
