The adoption of phase change materials (PCMs) for thermal energy storage in low‐ and medium‐temperature settings is witnessing a notable surge. However, the lesser conductivity (TC) poses noteworthy challenge to PCM's heat transfer capabilities. One solutions augment TC incorporating nanoparticles PCM. Nevertheless, often clump together after several cycles due poor compatibility weak interfacial strength. Functionalization methods have been proposed address this issue, offering improved performance applications. Herein, graphene nanoplatelets (GNP) functionalized (FGNP) are dispersed into A70 PCM at mass fractions ranging from 0.1 1.0 wt% using two‐step method. Fourier transform infrared analysis confirms successful integration FGNP without altering its chemical characteristics. Adding increases by 140.88%, with just 3.02% decrease latent enthalpy. pure GNP (1.0 wt%) improves 48.83%. engineered nano‐PCMs exhibit robust stability even undergoing 1000 cycles, remaining unchanged up 414.64 °C. This exceptional makes formulated nanoenhanced suitable sustainable

Abstract This study examines the intricate dynamics between oil prices and renewable energy investments in Italy during initial phase of CoronaVirus Disease 2019 pandemic, a period characterized by significant economic social upheaval. Utilizing advanced empirical techniques, such as Partial Wavelet Coherency analysis, Time-Varying Granger Causality, Robinson Log-Periodogram tests, well Machine Learning (ML) regressions, this research uncovers nuanced insights into interplay series including biomass, solar, hydro, wind, geothermal. Key findings indicate predominant in-phase relationship with leading most series, unidirectional causality from renewables to several instances, highlighting potential influence on market dynamics. In robustness checks, ML models further elucidate impact, geothermal sources showing importance scores. These are critical for policymakers stakeholders aiming enhance security transition towards sustainable amidst global crises.

Abstract Climate change and environmental degradation threaten the world global economic conditions. As one of countries’ most important components, financial sector might be an effective tool for reducing even reversing degradation. The can affect sustainability through its lending investment practices. play a role in financing sustainable projects businesses, helping reduce CO 2 emissions. By aligning objectives with protection, support transition to more future by degradation’s negative impacts.
