Innovating Leishmaniasis Treatment: A Critical Chemist's Review of Inorganic Nanomaterials.

Leishmaniasis, a critical Neglected Tropical Disease caused by Leishmania protozoa, represents a significant global health risk, particularly in resource-limited regions. Conventional treatments are effective but suffer from serious limitations, such as toxicity, prolonged treatment courses, and rising drug resistance. Herein, we highlight the potential of inorganic nanomaterials as an innovative approach to enhance Leishmaniasis therapy, aligning with the One Health concept by considering these treatments' environmental, veterinary, and public health impacts. By leveraging the adjustable properties of these nanomaterials─including size, shape, and surface charge, tailored treatments for various diseases can be developed that are less harmful to the environment and nontarget species. We review recent advances in metal-, oxide-, and carbon-based nanomaterials for combating Leishmaniasis, examining their mechanisms of action and their dual use as standalone treatments or drug delivery systems. Our analysis highlights a promising yet underexplored frontier in employing these materials for more holistic and effective disease management.

Recent Advances in Metal–Organic Frameworks for the Surface Modification of the Zinc Metal Anode: A Review

Aqueous zinc ion batteries (AZIBs) are considered as one of the most promising energy storage technologies due to their advantages of being low in cost, high in safety, and their environmental friendliness. However, dendrite growth and parasitic side reactions on the zinc metal anode during cycling lead to a low coulombic efficiency and an unsatisfactory lifespan, which seriously hinders the further development of AZIBs. In this regard, metal–organic frameworks (MOFs) are deemed as suitable surface modification materials for the Zn anode to deal with the abovementioned problems because of their characteristics of a large specific surface area, high porosity, and excellent tunability. Considering the rapidly growing research enthusiasm for this topic in recent years, herein, we summarize the recent advances in the design, fabrication, and application of MOFs and their derivatives in the surface modification of the zinc metal anode. The relationships between nano/microstructures, synthetic methods of MOF-based materials, and the enhanced electrochemical performance of the zinc metal anode via MOF surface modification are systematically summarized and discussed. Finally, the existing problems and future development of this area are proposed.

Advances in Metal Oxide‐based Nanocatalysts for Biodiesel Production: A Review

AbstractThe demand for renewable fuels has risen as a result of increasing human population, urbanization, industrialization, and transport systems. Biodiesel production using metal oxide‐based heterogeneous catalysts is an efficient, sustainable, and environmentally friendly approach.

Since the last few decades, the metal oxides of alkali earth and transition metals and their composite materials have been used as nanocatalysts in the production of biodiesel fuel. Utilization of inorganic metal oxide nanoparticles (MONPs) and their composite materials in producing biodiesel has gained increased attention because of their advanced physical and chemical characteristics. In this review, the applicability of metal oxides and their nanocomposite‐based catalysts in biodiesel production, transesterification reactions with nanocatalytic systems, and the important parameters that affect these reactions are discussed.

Post Nitrogen Electrocatalysis Era From Li–N2Batteries to Zn–N2Batteries

AbstractMetal–N2batteries attract considerable research attention due to the dual‐functional characteristics applied in energy storage and conversion, as well as electrochemical artificial NH3yield. Nonetheless, it has been found that not all kinds of metal–N2batteries are suitable for combining the above two applications. Herein, recent advances in metal–N2batteries are summarized. First, the electrochemical reaction mechanisms for all types of metal–N2batteries, including organic Li/Na/Al–N2batteries and aqueous Zn/Al–N2batteries are discussed, and then, a critical assessment of current challenges and future applications is provided. Considering the different electrochemical reaction mechanism in the metal–N2batteries, the electrocatalytic performance for the reported catalyst cathodes is summarized and compared. Then, a multi‐dimensional feasibility and strategy analysis for the developments of rechargeable aqueous Zn–N2batteries is provided, including the three dimensions of cathode catalyst, electrolyte, and metal anodes. Last, specific suggestions and ideas for the further developments of the rechargeable aqueous Zn–N2batteries are put forward, with the hope of inspiring the further developments for the green, sustainable, and high‐energy‐density metal–N2systems in the future.

2,5‐Dimercapto‐1,3,4‐Thiadiazole (DMCT)‐Based Polymers for Rechargeable Metal–Sulfur Batteries

Organosulfur materials are a sustainable alternative to the present‐day layered oxide cathodes in lithium‐based batteries. One such organosulfur material that was intensely explored from the 1990s to early 2010s is 2,5‐dimercapto‐1,3,4‐thiadiazole (DMCT). However, research interest declined as the electrode reactions with DMCT were assumed to be too sluggish to be practical. Armed with the advances in metal–sulfur batteries, we revisit DMCT‐based materials in the form of poly[tetrathio‐2,5‐(1,3,4‐thiadiazole)], referred to as pDMCT‐S. With an appropriate choice of electrode design and electrolyte, pDMCT‐S cathode paired with a Li‐metal anode shows a capacity of 715 mA h g−1 and a Coulombic efficiency of 97.7% at a C/10 rate, thus quelling the concerns of sluggish reactions. Surprisingly, pDMCT‐S shows significantly improved long‐term cyclability compared to a sulfur cathode. Investigations into the origin of the stability reveals that the discharge product Li‐DMCT in its mesomeric form can strongly bind to polysulfides, preventing their dissolution into the electrolyte and shuttling. This unique mechanism solves a critical problem faced by sulfur cathodes. Encouragingly, this mechanism results in a stable performance of pDMCT‐S with Na‐metal cells as well. This study opens the potential for exploring other organic materials that have inherent polysulfide sequestering capabilities, enabling long‐life metal–sulfur batteries.
