Summary: In this study, a simple strategy was demonstrated for constructing low-tortuosity through-pores in both vertical and planar directions of electrodes by casting large particles into single-particle-layer electrodes. Through multi-scale characterizations and simulations, correlations between material/electrode structures, electrolyte permeability, polysulfide migration, and sulfur reactions were elucidated. The high-loading and dense sulfur cathode fabricated by this method delivers a high specific capacity at a very low electrolyte/sulfur ratio.

Summary: Moisture absorption in wood cell wall structure causes swelling of wood due to sorptive action of carbohydrate wood polymers, leading to transverse contraction and slight elongation of cellulose crystals. These deformations are reversible during moisture desorption, attributed to swelling forces from longitudinal and lateral expansions of non-crystalline cellulose molecules and hemicellulose.

Summary: We investigated the effects of Cu doping on the structure, morphology, magnetic properties, cytotoxicity, and biocompatibility of ZnO nanostructures. Our results show that the incorporation of Cu2+ ions inhibits the growth of nanorods and leads to the disappearance of nanorod morphology at higher doping levels. X-ray photoelectron spectroscopy confirms that Cu ions substitute Zn2+ sites in their divalent state. Magnetic measurements reveal a significant change in the magnetic features due to doping. Cytotoxicity assessment demonstrates that Cu-doped ZnO samples are non-toxic. Our findings suggest the potential usefulness of Cu doping in spintronic/magnetic media devices and as a promising approach for new functional biomaterials in biomedical applications.

Summary: We investigated the use of carboxylic acid-terpene-based deep eutectic solvents (DESs) as skin permeation enhancers. Through transdermal experiments, we found that DESs with longer hydrocarbon chains can enhance the skin permeability of both hydrophilic and hydrophobic drugs. We also evaluated the structural changes in the stratum corneum and observed that DESs disrupt lipid layers and enhance permeation. Overall, DESs with longer hydrocarbon chains can be used to improve drug permeation while reducing skin irritation.

Summary: A thin molecular sieve film made of beta-cyclodextrin was used to decorate the surface of an electrospun cellulose acetate membrane as the separator for lithium-sulfur batteries. The beta-cyclodextrin physically blocked and chemically trapped polysulfides, while also dramatically speeding up ion transport. The addition of graphite carbon as the upper current collector further improved the battery performance. This study demonstrates the potential of the funnel effect of the separator for fast charging of lithium-sulfur and other lithium secondary batteries.

Summary: In this study, a sandwich-like structured bacterial cellulose/zeolite (BC/zeolite) hybrid hemostat was successfully fabricated through an in situ biosynthesis process. This hemostat effectively addresses the potential thrombotic risk caused by tiny zeolite residue in bleeding wounds. The BC/zeolite-Ca hemostat, after calcium ion-exchange process, significantly reduces the in vitro blood clotting time from 7.5 +/- 0.3 min to 2.2 +/- 0.3 min. This work provides a low-cost, eco-friendly, and low-risk approach for pre-hospital hemostasis applications through in situ biosynthesis of BC- and zeolite-based hybrid materials.
