A Review of the Strategies Used in the Recovery and Passivation of Lead in Lead‐Based Perovskite Solar Cells: Balancing Device Efficiency, Toxicity, and Environmental Sustainability

open access: yesNatural Sciences, Volume 6, Issue 1, January 2026.
Lead‐based perovskite solar cells deliver outstanding power conversion efficiencies, yet their commercialization is constrained by concerns over lead toxicity and stability challenges. Advanced encapsulation and chemical passivation techniques can significantly suppress lead leakage while improving long‐term device stability.

Microbial Deterioration Potential and Mitigation Strategies in Blended Cement Structures: A Review

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Microbial‐induced deterioration (MID) is a threat to the durability of cement‐based materials (CBMs) particularly in sewer and wastewater systems. Whereas blended cements incorporating supplementary cementitious materials (SCMs) offer environmental benefits such as reduced carbon (IV) oxide (CO2) emissions and enhanced mechanical performance, their ...

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

open access: yesInternational 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.

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

open access: yesInternational Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.
