Summary: This study examines the impact of green energy finance and ecological development on eco-friendly environments in the United States, China, and France from 2000 to 2020. The findings suggest that green energy finance and ecological development have a negative influence on emissions of CO2, SO2, and NO, indicating a well-developed eco-friendly environment. However, economic development and urbanization, which are positively correlated with pollutant emissions, have a detrimental effect on eco-friendly environments. The study also identifies a unidirectional causation relationship between eco-friendly environments and ecological development, as well as bidirectional links among urbanization, economic growth, and eco-friendly environments.

Summary: Conjugated polymer-based energy-harvesting devices offer advantages in terms of low toxicity, high flexibility, and low-cost large-area integration. Organic thermoelectric (OTE) devices have attracted attention for efficiently converting low-temperature waste heat into electricity, but the use of environmentally toxic solvents and acids hinders their truly green development. In this study, eco-friendly strategies were proposed for a high-performance OTE device based on poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) by incorporating vitamin C as an additive. The strategy improved the electrical conductivity and Seebeck coefficient, leading to a high thermoelectric power factor. Additionally, a fully degradable OTE device was demonstrated, providing an eco-friendly solution for the fabrication of high-performance, wearable, and biocompatible OTE devices.

Summary: This study investigated the performance of low-power energy harvesting wireless sensor networks (WSNs) and proposed an optimal loop interference relay selection. The crucial role of the log-normal distribution method in characterizing the network's constraints was proven. The system achieved the lowest overall ergodic outage probability and performed the best with an energy harvesting time switch of 0.175. Results also showed that the system without a direct link performed the worst with increasing signal-to-noise ratio (SNR) and the system performance improved with more relays deployed.
