Advanced Healthcare Materials, EarlyView.Gellan gum fluid gel (FG) enables controlled ocular delivery of mesenchymal stromal cell (MSC)‐derived extracellular vesicles (EV). Its shear‐thinning, solid‐liquid‐solid rheology ensures prolonged ocular retention. Sustained MSC‐EV release (∼18% in 6 hrs) supports effective EV ocular delivery.

Interaction behavior between coarse-particle pyrite and fine-particle pyrite in flotation
Scientific ReportsPyrite is commonly associated with gold deposits and serves as a gold-bearing mineral. The flotation recovery of gold-bearing pyrite generally determines the overall gold recovery.

Advanced Healthcare Materials, EarlyView.Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.
