Manganese MOF-derived ruthenium-doped MnO catalyst for enhanced oxygen evolution reaction and energy-efficient lead recovery.

Advanced, efficient, and eco-friendly technologies are essential for the safe recycling of spent lead-acid batteries for minimizing their environmental impact by mitigating toxic wastes and promoting resource sustainability by recovering valuable lead. Herein, we proposed a simple, zero-emission electrochemical strategy to recover metallic lead the direct electrolysis of lead-acid batteries. MnO@RuO with a layered structure of stacked nanosheets was prepared facile hydrothermal and annealing methods.

Synergistic Electronic Modulation via Dual-Atomic Site Engineering in RuCo Hybrids for Optimized Hydrogen Adsorption and Enhanced Overall Water Splitting.

Developing hydrogen as a clean, sustainable energy carrier relies on green electricity-derived large-scale water splitting production. However, it is greatly limited by the inherently sluggish reaction kinetics and high energy barriers associated with proton reduction. Herein, the study proposes heterostructured RuCo-nanocubes (RuCo-NC) engineered through phase control and metal integration to optimize hydrogen adsorption, enhancing catalytic efficiency by reducing energy barriers and improving mass and charge transport.

Nanotechnology-based approaches for emerging and re-emerging viruses: Special emphasis on COVID-19.

In recent decades, the major concern of emerging and re-emerging viral diseases has become an increasingly important area of public health concern, and it is of significance to anticipate future pandemic that would inevitably threaten human lives. The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly emerged virus that causes mild to severe pneumonia. Coronavirus disease (COVID-19) became a very much concerned issue worldwide after its super-spread across the globe and emerging viral diseases have not got specific and reliable diagnostic and treatments.
