The conductivity enhancement in solvent treated PEDOT:PSS is a result of the solvation of the PSS shell, leading to the release of conductive PEDOT in the core.

Treatment of PEDOT:PSS films with a superacid results in remarkable improvement of thermoelectric performance with a power factor of 142 μW m−1 K−2.

The discovery of aggregation-induced emission (AIE) phenomenon about two decades ago has ever since changed our mutual understanding about the aggregation of organic luminogens that always quench the fluorescence of...

This paper summarizes the latest development of PEDOT:PSS-based composites with inorganic additives and carbon nanostructures for thermoelectric applications.

Artificial nitrogen conversion reactions, such as the production of ammonia via dinitrogen or nitrate reduction and the synthesis of organonitrogen compounds via C−N coupling, play a pivotal role in the modern life. As alternatives to the traditional industrial processes that are energy-and carbon-emission-intensive, electrocatalytic nitrogen conversion reactions under mild conditions have attracted significant research interests. However, the electrosynthesis process still suffers from low product yield and Faradaic efficiency, which highlight the importance of developing efficient catalysts. In contrast to the transition-metal-based catalysts that have been widely studied, the p-block-element-based catalysts have recently shown promising performance because of their intriguing physiochemical properties and intrinsically poor hydrogen adsorption ability. In this Perspective, we summarize the latest breakthroughs in the development of p-block-elementbased electrocatalysts toward nitrogen conversion applications, including ammonia electrosynthesis from N 2 reduction and nitrate reduction and urea electrosynthesis using nitrogen-containing feedstocks and carbon dioxide. The catalyst design strategies and the underlying reaction mechanisms are discussed. Finally, major challenges and opportunities in future research directions are also proposed.

The runaway production and consumption of oilbased plastics are key drivers of global warming and the increased carbon footprint. Besides, most of this plastic debris ends up in the oceans and constitutes about 80% of all marine debris. This pollution problem calls for a seismic shift to eco-friendly plastics and marine biodegradable ones. Unlike other biobased polymers, polyhydroxyalkanoates (PHAs) take pride in their degradation in soil and marine environments. This intriguing marine biodegradation property of PHAs sets it apart as the best choice to curb microplastics, particularly in marine ecosystems. PHAs have also grown in popularity due to other quintessential properties such as biocompatibility, structural variety, and similarity to conventional plastics in terms of physical properties. PHAs are being widely researched for various applications, including packaging, medical, energy, and agriculture. This perspective comprehensively focuses on the state-of-art production and applications of PHA plastics as well as the practical recycling strategies for postconsumer PHAs. The innovative "next generation industrial biotechnology" (NGIB) is well covered in this perspective. Moreover, the nexus between end-of-life strategies and life cycle assessment (LCA) of PHAs waste is elucidated to understand its impact on the environment thoroughly.
