Inorganic-organic mesoporous hybrid segregators for selective and sensitive extraction of precious elements from urban mining.

This study aimed to develop a highly selective extraction protocol for gold (Au) ions from electronic urban waste (EUW) using simple, low-cost Inorganic-organic mesoporous hybrid segregators. The unique features of mesoporous hybrid segregator architectures are of particular to ensure effective adsorption system in terms of selective and sensitive recovery of Au ions from EUW. The segregator platform featured 3D micrometric, mesocage double-serrated plant-leaf-like γ-AlO sheets with hierarchy surfaces containing tri-modal mesopores interiorly and uniformly arranged toothed edges of ~20-40 and ~15 nm groove width and depth at the exterior surfaces, respectively.

Hemostatic and antibacterial PVA/Kaolin composite sponges loaded with penicillin-streptomycin for wound dressing applications.

Hemorrhage is the major hindrance over the wound healing, which triggers microbial infections and might provoke traumatic death. Herein, new hemostatic and antibacterial PVA/Kaolin composite sponges were crosslinked using a freeze-thawing approach and boosted by penicillin-streptomycin (Pen-Strep). Physicochemical characteristics of developed membranes were analyzed adopting Fourier transformed infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), a thermal gravimetric analyzer (TGA), and differential scanning calorimetry (DSC).

Anisotropic alignments of hierarchical LiSiO/TiO @nano-C anode//LiMnPO@nano-C cathode architectures for full-cell lithium-ion battery.

We report on low-cost fabrication and high-energy density of full-cell lithium-ion battery (LIB) models. Super-hierarchical electrode architectures of LiSiO/TiO@nano-carbon anode (LSO.TO@nano-C) and high-voltage olivine LiMnPO@nano-carbon cathode (LMPO@nano-C) are designed for half- and full-system LIB-CR2032 coin cell models.
