Self-healing polymers (SHPs) are advanced materials designed to autonomously repair damage, inspired by biological systems. Initially, SHPs focused on embedding healing agents within polymers that would release upon damage. Over time, technological advancements have led to the integration of dynamic covalent and supramolecular bonds, enabling molecular-level self-repair without external intervention. SHPs now address not only mechanical integrity but also the recovery of electrical and optical functionalities. Mechanisms for self-healing include encapsulation of healing agents, dynamic bonds, nanomaterials responding to external stimuli, and shape memory effects (SMEs). Despite significant progress, challenges remain in balancing mechanical strength and self-healing efficiency. Research is ongoing to enhance the interplay between chemical and physical processes in self-repair, with a focus on sustainable materials. Synthesis methods for SHPs involve various chemical processes, such as microencapsulation, dynamic cross-linking, and reversible bonding techniques. Applications of SHPs span automotive, electronics, and energy storage industries, offering benefits like reduced maintenance costs, extended lifespan, and improved durability. Recent innovations include high-performance polymers capable of operating in harsh environments and more commercially viable, eco-friendly materials.

The objective of this study was to investigate the evolution of technology commercialization literature to determine the conceptual trends over the past 50 years to identify the key scientific documents in this field, which is the basis for knowledge development, and fill the gap between the field of commercialization and other knowledge networks and scientific structures. This study is applied scientometric and co-citation analysis has been used. We calculated the betweenness centrality index of the nodes and combined it with the burstness index of scientific documents over time to calculate the sigma index, which we then used to identify transformative documents. The study found that seven scientific documentaries, based on the sigma index, could potentially change the field of knowledge about commercializing technology. These documentaries were part of a co-citation network with 855 articles taken from the Web of Science (WOS) database. The results of the analysis showed that the betweenness centrality index and the burstness index by themselves can't give a full picture of how knowledge trends are changing in the field of technology commercialization. The sigma index, on the other hand, did a better job of this.

Given the significant growth of the world's population, several serious issues have arisen, including pollution, economic challenges, and environmental problems. To address these environmental issues, many construction experts are actively seeking new flexible techniques. In this context, nanotechnology emerges as a critical field aimed at enhancing the efficiency of the built environment and plays a vital role in addressing prominent future challenges. The nanotechnology revolution has had a positive impact on architecture. The use of nanotechnology is considered one of the most successful modern methods for achieving sustainable buildings with high operational efficiency. This study aims to examine the role of nanotechnology in achieving sustainable architecture through a descriptive-analytical approach. The findings of this research include the advantages of nanotechnology in the construction and improvement of building quality, the enhancement of material quality, energy savings, and consequently sustainable architecture and environmental sustainability. Additionally, it explores strategies for energy conservation in buildings and achieving sustainable architecture using nanomaterials and technology.
