Summary: A sol epitaxial fabrication strategy was developed to create metal-insulator transition nanofibers (MIT-NFs), which could be further assembled into self-standing two-dimensional membranes and three-dimensional aerogels with structural robustness. The resulting MIT materials exhibited solid-solid phase change properties, while maintaining shape stability and thermal reallocation properties.

Summary: Hydrogels and nanofibers have been established as popular materials for biomedical applications, but they are typically used separately due to their distinct attributes and shortcomings. However, integrating nanofibers with hydrogels offers the potential for synergistic combination of their functionalities while mitigating their drawbacks. This review presents recent efforts in developing nanofiber-composite hydrogels, with a focus on nanofiber processing techniques, and introduces notable examples of their implementation in biomedical applications.

Summary: This study constructed a flexible sensor based on mesh PANI/Ti3C2Tx composite nanofibers, which exhibited excellent performance in NH3 sensing response and flexible bending stability. The improved sensing properties can be attributed to the formation of Schottky junctions between PANI and Ti3C2Tx nanosheets, improved protonation degree of PANI, and the special three-dimensional mesh fiber structure.

Summary: This paper presents a method of manufacturing nanofiber yarns (NFY) using a simplified dry electrospinning system to produce self-assembling functional NFY capable of conducting electrical charge. By enhancing the conductivity and allowing fibers to align and grow in a twisted pattern, the longer the electrospinning continues, the longer and more uniformly twisted the NFY becomes. Additionally, this process reduces the electric field required for NFY production.

Summary: A common practice in Saudi Arabia is to only insulate outer walls and windows of buildings, neglecting other components such as the roof and doors. This study aims to test the effectiveness of this practice by quantifying the contribution of each building component to the overall air-conditioning load. The findings highlight the importance of the roof and suggest an optimized selection of insulation materials for cost-effective and energy-saving insulation.

Summary: This study investigated the influence of cutting parameters on the cutting performance of turning grey cast iron. Increasing the feed rate resulted in higher cutting force, temperature, and surface roughness. Increasing the cutting speed and nose radius also increased the temperature, but reduced the cutting force. Mathematical calculations were used to estimate the percentage increase in cutting temperature and surface roughness with changes in feed rate, cutting speed, and nose radius. Experimental results and mathematical calculations were in good agreement. Additionally, optimization using the desirability function tool was used to maximize material removal rate while minimizing measured responses.
