The global energy landscape is undergoing a profound transformation, with wind energy gaining increasing prominence due to its clean and renewable nature. However, as installed wind power capacity expands, disposal of waste wind turbine blades (WWTB) has emerged as a significant challenge. These blades are predominantly composed of epoxy resin (EP) polymers, carbon fibers (CFs), and glass fibers (GFs). Improper disposal exacerbates environmental concerns and leads to loss of valuable resources, particularly carbon-based materials. Pyrolysis technology, a versatile and environmentally sustainable method for resource recovery, has garnered considerable attention for WWTB disposal. This work presents a comprehensive review of pyrolytic recycling of WWTB, focusing on principles and classifications of pyrolysis technology, key factors influencing the pyrolysis process, as well as pyrolysis methods, equipment, products, and their applications. Through in-depth analysis of current research, this review identifies critical unresolved issues and provides a forward-looking perspective on emerging research trends. The review highlights that pyrolysis can effectively recover glass fibers and carbon fibers with mechanical property retention depending on process conditions, and that catalytic pyrolysis can enhance the quality of recovered products. Economic analysis indicates that collaborative disposal methods can improve cost-effectiveness. Future research should focus on optimizing process parameters for large-scale industrial application and developing more efficient catalysts to improve product selectivity and fiber quality.

Microplastics (MPs) are persistent emerging contaminants ubiquitously distributed in soil-groundwater environments, where their aggregation and transport critically govern pollutant fate and ecological risks. Natural organic matter (NOM), a complex assemblage of organic compounds, interacts with MPs and porous media via hydrogen bonding, π-π interactions, hydrophobic effects, and electrostatic binding, thereby modulating MP surface properties and environmental behavior. This review systematically synthesizes the mechanisms by which NOM influences MP aggregation and transport, with emphasis on the distinct roles of humic substances, proteins, and extracellular polymeric substances (EPS), and their synergistic modulation with solution chemistry (pH, ionic strength, ion type). Additionally, NOM accelerates MP aging and alters surface characteristics, consequently impacting transport capacity. Current research limitations are identified, and future directions are proposed to inform MP pollution risk assessment and management strategies. Key findings indicate that NOM generally enhances MP stability and mobility at low ionic strengths, while high ionic strengths may induce aggregation depending on NOM type and ion valence. Humic substances predominantly increase electrostatic repulsion, whereas proteins and EPS can bridge particles, promoting aggregation. Aging processes, accelerated by NOM photochemical activity, increase surface oxygen functionality and hydrophilicity, further altering transport. The review underscores the need for systematic studies under environmentally relevant conditions to predict MP fate accurately.

Microneedle (MN)-based transdermal delivery systems enhance skin permeability by creating microscale conduits through the stratum corneum, enabling controlled and sustained release of therapeutics. Nevertheless, conventional MN designs predominantly rely on passive diffusion, resulting in shallow drug penetration depth and limited spatial distribution range, which significantly restricts their therapeutic efficacy in complex biological environments. Emerging advancements have integrated gas therapy into MN platforms to overcome these limitations. The released therapeutic gases facilitate deeper drug penetration via propulsion and also exhibit inherent bioactivity, contributing to synergistic treatment outcomes. This review summarizes the mechanisms, design strategies, and applications of gas-releasing MN systems, while highlighting key scientific and translational challenges, including the precise regulation of gas release, the development of multi-gas synergistic systems, the extension to deep-tissue therapy, and the assurance of biosafety. Future directions emphasize the construction of intelligent, stimuli-responsive MNs, the integration of interdisciplinary technologies to enhance delivery depth, and the establishment of standardized, scalable manufacturing frameworks. Collectively, this work aims to advance gas-releasing MN technology toward precise, efficient, and controllable therapeutic applications, bridging the gap between laboratory research and clinical translation.
