Pathways to a Fully Renewable Energy System in Iran: A Scenario‐Based Analysis Across Power, Heat, Transport, Industry and Desalination

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This study assesses three transition pathways for Iran's energy system to 2050. Only the best policy scenario (BPS) achieves 100% renewables, with over 93% of primary energy from solar photovoltaics, extensive storage, and power‐to‐X technologies. In the BPS, CO2 emissions fall to zero and the levelised cost of electricity declines to €24.7/MWh by 2050.

Review and Integrated Framework for Deep‐Sea Mineral Resources, Ecological Influence, and Future Development

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
As global industrialization advances and land‐based resources decline, deep‐sea resource development is becoming increasingly vital. The deep sea is rich in minerals such as polymetallic nodules, polymetallic sulfides, and cobalt‐rich crust. However, deep‐sea ecosystems and geochemical cycles can be severely impacted by extensive mineral mining.

A Trend‐Based Two‐Stage Framework for Tin (Sn) Recovery From Waste PCBs via Bioleaching and Thermally Activated Bentonite Adsorption

Journal of Chemistry, Volume 2026, Issue 1, 2026.
This study proposes a two‐stage, trend‐based framework for tin (Sn) recovery from waste printed circuit boards (PCBs) by integrating Acidithiobacillus ferrooxidans–mediated bioleaching with thermally activated bentonite adsorption. Bioleaching performance was optimized using a central composite design–based response surface methodology (CCD‐RSM), which
