Vertically Aligned Ion Pathways for Fast Conduction and Uniform Lithium Deposition in Solid‐State Batteries

open access: yesCarbon Energy, EarlyView.
Under an alternating electric field, the lithiated halloysite nanotubes (HNTs–SO₃Li) self‐assemble into a perpendicular orientation, creating continuous pathways with low tortuosity that markedly enhance room‐temperature ionic conductivity. The shortened diffusion path within this alignment enables rapid Li⁺ transport, while the establishment of a ...

Immobilization ofRhizomucor mieheilipase onto montmorillonite K-10 and polyvinyl alcohol gel

open access: yesBiocatalysis and Biotransformation, 2019
Immobilization of enzymes from different sources on various supports in designed systems increases enzymes’ stability by protecting the active site of it from undesired effect of reaction environment. Also, immobilization decreases the cost of separation and facilities the reuse of the enzymes.

Enhanced pH and thermal stabilities of invertase immobilized on montmorillonite K-10 [PDF]

open access: yesFood Chemistry, 2006
Abstract Invertase was adsorbed onto micro-porous acid-activated montmorillonite clay (K-10) by two procedures, namely adsorption and covalent binding. The immobilized enzymes were characterized by XRD, surface area measurements and 27Al NMR. XRD measurements revealed an expansion of clay layers due to immobilization which suggests that intercalation

Quantification of rheological parameters in deep‐sea mining plumes

open access: yesDeep Underground Science and Engineering, EarlyView.
This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...
