environment to nanotechnology in clay minerals

The use of natural clays for the removal of dyes from wastewater, an important part of environmental remediation, is desirable due, not least, to their low cost. Palygorskite (PAL), a rigid-structure clay, is a good candidate for use in the elimination of industrial effluents, based on its exceptional adsorptive properties.

"The coal mining application is meant to be at a stage that you could hand to a commercial builder or user three years from now," Plata says.

Clay minerals are commonly used in the pharmaceutical industry as ingredients or additives due to their thermal and chemical stability, biocompatibility, low toxicity, and relative abundance. Researchers have extensively investigated their use as advanced drug delivery systems as well, including to deliver various metallic nanoparticles.

The performance and mechanism of denitrification enhanced by three clay minerals, montmorillonite (Mmt), illite and kaolinite, were first studied. Batch experiments indicated that clay minerals significantly enhanced denitrification at certain concentrations (0.1–1 g/L). The denitrification rate with 1 g/L Mmt was increased by 5.0-fold. The mechanism of clay minerals …

In 2011, the nuclear accident at Fukushima, Japan, resulted in the deposit of radioactive cesium (radiocesium) into habitats in the vicinity. A decade after the accident, researchers have collated ...

This book examines the health effects of exposure to bentonite kaolin and selected clay minerals. Despite the ubiquitous exposure of the general population to low concentrations of montmorillonite and kaolinite the main components of bentonite and kaolin respectively and other clay minerals no data are available on its effects. Long-term …

A part of the clay mineral assemblage has been attributed to a montmorillonite-organic complex, which appears to be modified or destroyed in the alkaline sea-water environment. An examination of buried muds of Tertiary age has indicated that little or no alteration of clay minerals takes place in shales to a depth of several thousand feet.

The fine-clay fraction is dominated by smectite, mica, and kaolinite. Smectites are concentrated at two places in the toposequence: an upper zone, which includes the soil horizons rarely reached by the lake-level variation; and a lower zone, which includes the surface horizon within the area of seasonal lake-level variation.

Owing to their abundance, ecofriendliness, and multifaceted properties, natural clay minerals are among the most trusted and widely utilized materials on earth. One of the most exciting and latest findings of these minerals is that their layers can be exfoliated into individual flakes and reassembled to produce freestanding and flexible membranes. A tremendous surge …

Nevertheless, the original clay mineral assemblages undergo a significant homogenisation due to the destruction of most of the transformed and neoformed minerals during fluvial transport. As a consequence, inherited clay minerals (illite, chlorite and kaolinite) usually dominate the assemblages recorded in the downstream alluvial sediments.

Nanofabrication involving clay is a distinct field, because it departs from the conventional field of nanotechnology (eg, nanoelectronics, nanomaterials), and is far more challenging than conventional applications (eg, cell phones, computers, sensors, clothes, and other industrial products).

The stepwise hydration of clay minerals has been observed repeatedly in studies, but the underlying mechanism remains unclear. Previous numerical studies confirmed the presence of one-water layer (1W) and two-water layer (2W) hydration states. However, the undisturbed transition between these hydration states has never been captured. Using …

Clay minerals are a group of aqueous silicates that make up the bulk of clay deposits and most of the soils and determine their physicochemical, mechanical, and other properties. Clay minerals are the product of weathering mainly of aluminosilicates and silicates of igneous and metamorphic rocks on the day surface.

The presence of clay minerals in nature predates humans. With the advancement of nanotechnology and the increase in need for sustainable development of modern society, naturally occurring clay minerals and their man-made varieties provide hopes for further improving the quality of human life.

Clay minerals have been, historically, salient in their role as an adsorbent for disposal and storage of hazardous chemicals for environmental protection (Xu et al., 2017). They are an inherently occurring material possessing particles that range in size downward from 2 µm, resulting in large surface areas suitable for high efficiency of ...
