Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.

Conductivity anisotropy of polyphosphazene-montmorillonite composite electrolytes

, 1996
The conductivity of an ordered polyphosphazene Na+-montmorillonite composite has been measured perpendicular (sigma(para)) and parallel (sigma(perp)) to the montmorillonite layers, and the sigma(para)/sigma(perp) is about 100.

Effect of montmorillonite as additive on the properties of cement-based composites

Science and Engineering of Composite Materials, 2012
The aim of this study was to investigate the effect of montmorillonite as additive on the properties of cement paste and mortar. Montmorillonite was used at 0%, 5%, 10% and 15% additive by weight of cement, and the water/cement ratios of 0.45 and 0.55 ...

Recent Paradigms in Nanomaterial‐Assisted Electrochemical (Bio) Sensing for Food Quality and Safety Analysis: A Critical Review

Food Safety and Health, EarlyView.
ABSTRACT Rising global demand for safe and unadulterated foods has accelerated the need for rapid, low‐cost, and portable analytical technologies. Traditional laboratory methods, although accurate, are often labor‐intensive and unsuitable for decentralized, real‐time monitoring. In response, nanomaterial‐assisted electrochemical sensors have emerged as

Local Structures of Se and Br in Cretaceous–Paleogene Boundary Sediments and Concentration Effects of Ferrihydrite Originating From Impact Ejecta

Geological Journal, EarlyView.
Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.

THE REACTIONS OF SOLUBLE ALUMINIUM WITH MONTMORILLONITE

Journal of Soil Science, 1973
Summary The amount of aluminium sorbed by calcium bentonite from basic aluminium chloride solutions depends on the ratio of OH to A1 in the original solution. Except when OH/A1 = 0, only part of the sorbed A1 is exchanged by dilute solutions of barium or calcium chlorides and the exchange capacity of the clay ...
