Remediation of Organic Pollutant for Wastewater Treatment by Employing Sustainable Graphene Oxide/NiO‐ZrO2/Zeolite Ternary Composite Material

CleanMat, EarlyView.
Graphene oxide/NiO‐ZrO2/zeolite ternary composite was synthesized hydrothermally. Efficient adsorption of Congo red onto GO/NiO‐ZrO2/zeolite composite was studied. ABSTRACT The present study employs a novel method for the synthesis of graphene oxide (GO) based ternary composite utilized for the adsorption of Congo red (CR), an anionic dye molecule. The

The release of aluminum from aluminosilicate minerals [PDF]

, 1978
--Acidified suspensions of Al-saturated kaolinite, montmorillonite, mica, illite, and biotite in 10-a M NaNO3 were potentiometrically titrated with 0.1 N NaOH and 0.1 N HNO3 in succession i a COz-free nitrogen atmosphere.

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

Deep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Clays and clay minerals for pollution control [PDF]

, 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 ...

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

Deep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

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

, 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.

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

Deep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Summary of recommendations of nomenclature committees relevant to clay mineralogy: report of the Association Internationale pour l’Etude des Argiles (AIPEA) Nomenclature Committee for 2006 [PDF]

, 2006
Brindley et al. (1951) reported the earliest efforts to obtain international collaboration on nomenclature and classification, initiated at the International Soil Congress in Amsterdam in 1950.

Decoding the origins and sources of clay minerals in the Upper Cretaceous Tununk Shale of south‐central Utah: Implications for the pursuit of climate and burial histories

The Depositional Record, 2020
Clay minerals in fine‐grained marine sedimentary successions are most commonly considered to be detrital in origin and have been used extensively by geologists as indicators of palaeoclimate conditions in the hinterland.
