Clays and clay minerals for pollution control

, 2013
Clay minerals are abundant, inexpensive, and generally safe materials for environmental applications. Because of their large specific surface area, high porosity, surface charge, and surface functional groups, clay minerals function as adsorbents ...

Engineering Nanoclay Edges to Construct Effective Polysulfide‐Trapping Interface for Markedly Enhanced Electrochemical Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A capsule‐shaped silicate clay (H‐ATP‐N2) rich in protonated edge hydroxyl groups (‐OH2+) is synthesized through a two‐step process involving microwave‐assisted acid treatment and N2 plasma etching to fibrous natural attapulgite. The H‐ATP‐N2 host inhibits the shuttle effect owing to the dominant adsorption mechanism–Lewis acid–base interaction between

'Black' soils in the southern Alps: clay mineral formation and transformation, X-ray amorphous Al phases and Fe forms

, 2006
Many soils in southern Switzerland have a black color, contain a large amount of soil organic matter (SOM) and seem to have some andic properties although they did not develop on volcanic parent material.

Closing the Loop in Agrivoltaics: A Radiative Cooling Coating for Synergistic Self‐Cleaning and Water Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanostructured photonic‐thermal coating enables radiative‐cooling‐induced condensation and water harvesting, establishing a self‐sustaining agrivoltaics microclimate loop that transforms PV panels into active climate regulators. The integration of photovoltaic (PV) panels into agricultural landscapes (i.e., agrivoltaics) offers a promising path for ...

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.

Thermal Analysis: A Complementary Method to Study the Shurijeh Clay Minerals [PDF]

International Journal of Mining and Geo-Engineering, 2015
Clay minerals are considered the most important components of clastic reservoir rock evaluation studies. The Shurijeh gas reservoir Formation, represented by shaly sandstones of the Late Jurassic-Early Cretaceous age, is the main reservoir rock in the ...

Risk assessment using IEUBK model for the Naica mine tailings

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Mexico has a long history of mineral extraction, during which limited environmental regulations allowed the accumulation of toxic waste near communities, primarily in rural or undeveloped areas. Some of these toxic substances, such as lead, pose significant risks to vulnerable populations, particularly children aged 0 to 7 years.

Comparative study of the adsorption of tetracycline on clay minerals with various nanostructures: allophane, halloysite, and montmorillonite

With the over-use of tetracycline (TC) and its ultimate accumulation in aquatic systems, the demand for TC removal from contaminated water is increasing due to its severe threat to public health.
