Carbon nanotubes (CNTs), owing to their superior electrical and mechanical properties, are a promising alternative to nonmetallic electrically conducting materials. In practice, cellulose as a low-cost sustainable matrix has been used to prepare the aqueous dispersion of cellulose-CNT (C-CNT) nanocomposites. However, the compatibility with conventional solution-processing and structural rearrangement for improving conductivity has yet to be determined.

Water is essential for the survival of all living things; however, its extensive use in agriculture, high-tech manufacturing, energy production, and the rapid development of the chemical and petroleum industries has led to significant contamination, making water pollution a major concern today. Ammonia is one of the most harmful contaminants present in water, posing significant environmental and health risks that require appropriate remediation methods. To remove ammonia from contaminated water, we employ Carbon Nanotubes (CNTs) and Activated Carbon (AC).

Article Synopsis
- Carbon nanotubes (CNTs) are highly conductive and strong nanomaterials that enhance the properties of polymers and are used in various applications.
- This study focused on the release of CNTs from epoxy nanocomposites when exposed to environmental conditions like UV light and water, as well as mechanical stresses like shaking.
- The findings showed a continuous release of CNTs during the weathering process, with a total release of about 0.5% of the embedded mass when combined with additional mechanical stresses, indicating potential impacts on human health and the environment.

Chemical fuel-driven supramolecular systems have been developed showing out-of-equilibrium functions such as transient gelation and oscillations. However, these systems suffer from undesired waste accumulation and they function only in open systems. Herein, we report non-equilibrium supramolecular polymerizations in a closed system, which is built by viologens and pyranine in the presence of hydrazine hydrate.
