Photocatalytic Disinfection of Bacteria by Sodium Light with Smectite Catalysts

, 2006
In this study, modifications of Wyoming smectite clay minerals are conducted using four types of metallic cations that cover the surface with Ag+, Zn2+, Ti4+ and Ag+/Zn2+ to form smectite catalysts and destroy bacteria.

Laponite Network Controls FGF‐2 Release and Drives Functional Nerve Regeneration via 3D‐Printed Nerve Wrap Interfaces

Small Methods, EarlyView.
We developed a 3D‐printed nerve interface integrating a biomimetic nanocomposite hydrogel with sustained delivery of thermostable FGF‐2. The bioactive interface supports Schwann cell activity and myelination while providing a regenerative microenvironment.

Experimental study of the electrokinetic behaviour of kaolinite–smectite mixtures

, 2017
International audienceThe evolution of the behaviour of kaolinite–smectite mixtures was studied using mechanical and electrokinetic tests. Oedometric tests showed that the compression index of the mixtures increases with increasing smectite percentage ...

Dietary Bentonite Supplementation Improves Growth Performance of Juvenile Nile tilapia Under Sub-Acute Aflatoxin B₁ Exposure

Journal of Xenobiotics
Previous studies evaluating bentonite in Nile tilapia have largely employed high-dose AFB1 challenge models (≥2 ppm in the diet), whereas information on its efficacy under sub-acute contamination conditions is limited. This study evaluated the effects of

Composition of Smectite from Maastrichtian Sediment of the Afikpo Basin, southeast Nigeria

Journal of Applied Sciences and Environmental Management, 2019
The sand, silt, shale and clay fractions soils derived from Maastrichtian sediments in the Afikpo Basin, southeastern Nigeria exhibit unusually high cation-exchange capacities. Smectite was identified by X-ray diffraction in all sample fractions and was

Bridging the small‐angle X‐ray scattering–X‐ray diffraction gap in disordered layered materials: the CLADIFFMOD unified framework

Journal of Applied Crystallography, EarlyView.
A unified multi‐scale framework is proposed for the consistent analysis of small‐angle X‐ray scattering (SAXS) and X‐ray diffraction (XRD) in disordered clay minerals, combining morphology, stacking and turbostratic contributions within a single formalism.
