An Expansion-Mitigant Binder for Stable Cycling of High-Loading Lithium-Sulfur Batteries.

Lithium-sulfur batteries with high sulfur content and mass loading are promising energy storage technologies due to sulfur's exceptional theoretical energy density. However, in practice, their actual capacity drastically decays when the sulfur cathode is loaded to the commercially required levels of 4 mg cm and above, significantly reducing the energy density. This reduction is due to the excessive formation of polysulfides during sulfur lithiation, which not only deteriorates battery performance through their detrimental shuttling but also results in substantial stress buildup due to their significantly larger volume compared to sulfur.

Technological trends in nanosilica synthesis and utilization in advanced treatment of water and wastewater.

Water and wastewater treatment applications stand to benefit immensely from the design and development of new materials based on silica nanoparticles and their derivatives. Nanosilica possesses unique properties, including low toxicity, chemical inertness, and excellent biocompatibility, and can be developed from a variety of sustainable precursor materials. Herein, we provide an account of the recent advances in the synthesis and utilization of nanosilica for wastewater treatment.

Intelligent modeling of dye removal by aluminized activated carbon.

Methylene blue (MB) is an important compound in textile and wood processing industries as well as in medical research for combating malaria parasites. Despite these versatilities, direct contact with human beings results in adverse health challenges, and contamination of water bodies affects aquatic biotas. Hence, it is important to treat MB-contaminated wastewaters before disposal into water bodies.
