The world is facing an ever-growing global energy crisis with unprecedented depth and complexity. The sustainable development of high energy density lithium-ion batteries for electric vehicles and portable electric devices has become a feasible way to deal with this problem. Silicon suboxides (SiO x ) have been deemed as one of the most promising anode materials because of their ultrahigh theoretical lithium storage capacity, proper working potential, natural abundance, and environmental friendliness. However, the mass utilization of SiO x -based anodes is severely obstructed by their low electrical conductivity and inevitable volume expansion. While lithium silicate and lithium oxide formed in the first lithiation process act as buffer layers to some extent, it is urgent to address the accompanying low initial Coulombic efficiency and unsatisfactory cycling stability. In this review, we summarized recent advances in the synthesis methods of SiO x -based materials. Besides, the benefits and shortcomings of the various methods are briefly concluded. Then, we discussed the effective combination of SiO x with carbon materials and designs of porous structure, which could considerably enhance the electrochemical performance in detail. Furthermore, progresses on the modified strategies, advanced characteristics and industrial applications for SiO x -based anodes are also mentioned. Finally, the remaining challenges encountered and future perspectives on SiO x -based anodes are highlighted.

Wearable electronic textiles (e‐textiles) have emerged as a transformative technology revolutionizing healthcare monitoring and communication by seamlessly integrating with the human body. However, their practical application has been limited by the lack of compatible and sustainable power sources. Various energy sources, including solar, thermal, mechanical, and wind, have been explored for harvesting, leading to diverse energy harvesting technologies, such as photovoltaic, thermoelectric, piezoelectric, and triboelectric systems. Notably, 2D materials have gained significant attention as attractive candidates for energy harvesting and storage in e‐textiles due to their unique properties, such as high surface‐to‐volume ratio, mechanical strength, and electrical conductivity. Textile‐based energy harvesters employing 2D materials offer promising solutions for powering next‐generation smart and wearable devices integrated into clothing. This comprehensive review explores the utilization of 2D materials in textile‐based energy harvesters, covering their preparation, fabrication, and characterization strategies. Recent advancements are highlighted, focusing on the integration of 2D materials and their practical implementations, shedding light on the performance and effectiveness of 2D‐material‐based energy harvesters in e‐textiles, and highlighting their potential as a sustainable alternative to conventional power supplies in wearable technologies.

“…For example, benzosultams, the fused cyclic analogues of sulfonamides, are among an important subclass of sulfonamide drug scaffolds with potent biological activities, 1c,2 whilst sultines (lactones of sulfinic acids) are well-known and important sulfur heterocycles that are present in various natu-ral and synthetic products, and can be used as valuable intermediates in drug discovery. 3,4 Accordingly, considerable attention has been focused on the development of efficient approaches to access these valuable scaffolds. However, the requirement for harsh/toxic conditions, moisture-sensitive and corrosive reagents, for example, sulfonyl halides, low atom-economy, elaborate starting materials, and limited functional group tolerance are disadvantages of many of the developed methods, which has severely limited the potential applications of sulfur-containing heterocycles.…”

Sulfur-containing heterocycles, where the S(R) moiety is in the cyclic structures, have been found tremendous applications in the field of chemistry, pharmaceutical, and materials sciences due to the unique chemical, biological and pharmaceutical activities. The recent years have witnessed an increasing interest in sulfur-containing heterocycles preparation and new methods were reported with modern methodologies and technologies through insertion of sulfur dioxide. The main objective of this mini-review is to overview the latest major developments for the synthesis of sulfur-containing heterocycles systems, mainly covering thermoinduced cyclization, photoinduced cyclization and electroninduced cyclization through the insertion of SO2. We wish to bring readers a comprehensive understanding and provide a positive outlook for the promising future of this field.
