Non-Game Bird habitat Associated With Haul Roads and Surface Mining for Bentonite Clay
A 2 year study was conducted to investigate possible differences in density and diversity of birds in relation to distance from mining haul roads and various aged mine spoils. Winter bird surveys and breeding bird counts were conducted during 1977 and 1978. Bird density and diversity were estimated …

A study of chemical interactions between the Marcellus shale and attapulgite and bentonite clays
… between the Marcellus shale and attapulgite and bentonite clays. The aim of this project was to determine if there were particular elemental changes that could be directly associated with either an attapulgite or bentonite clay. In this study, samples from two wells in West Virginia were …

Spatial Variability Analysis and Reclamation of Saline-Sodic Soils in the Northern Great Plains
… and 3) evaluate cation impact on dispersion of bentonite clay and selected soils. The research was conducted between 2013 and 2016 at Redfield (Argiustolls, Natrudolls, Calciustolls), White Lake (Argiudolls, Natrudolls), and Pierpont (Hapludolls, Natrudolls), in eastern South Dakota. A …

Slurry preparation of zeolite and metal - organic framework for extrusion based 3D – printing
… 3A and 4A monoliths powders, mixing it with bentonite clay, methyl cellulose, and PVA as a binder. The slurry preparation was carried out at room temperature. Once the 3D printed samples are dried at room temperature, a sintering process was performed to increase mechanical strength. To be …

Degradable nanocomposite preformed particle gel for chemical enhanced oil recovery applications
… with Poly (ethylene glycol) diacrylate and bentonite clay. Elastomeric rubber gel formed using 0.5% degraded preformed particle gel crosslinked with Poly(ethylene glycol) Diacrylate-200 is the most promising since it contains the least amount of degraded preformed particle gel (0.5%), …

Characterizing and Real-Time Monitoring of Various Types of Waters and Wastewaters Contaminated With Algae, Recycled Plastic Powders, and Clay Using the New Electrical Methods With Vipulanandan Models
… hydroxide (0.1 M), polylactic acid (PLA), and bentonite clay were prepared in four concentrations and monitored over ten days, generating seventy-two datasets. Physicochemical parameters, including pH, EC, TDS, resistivity, DO, CO₂, NO₃⁻, and Cl,⁻ were measured alongside impedance spectra …

Chemical and physical characterization of clay bodies
… warranted. The analysis of Whichford Potteries clays via a variety of analytical techniques has shown them to be a complex mix of both clay and non-clay minerals. 57Fe Mössbauer spectroscopy has highlighted the presence of both small and large particleα-Fe203, removable via acid washing. 19F MAS …

Colloid Formation Resulting from Alum Coagulation of Organic-Laden Sourcewaters
… be a proportional relationship. The presence of bentonite clay (used as the initial turbidity source) somewhat affected OC colloid formation by exerting some amount of coagulant demand, signified by decreasing OC colloid formation with increasing initial turbidity. Coagulation temperature had a …

Synthesis of Zr4+/Ag+ metal oxides modified zeolite for application in fluoride and pathogens removal from water
… at optimizing the synthesis of zeolite from bentonite clay using the response surface methodology (RSM). The process involved alkali dissolution of calcined bentonite clay through ultrasonication, followed by hydrothermal treatment to obtain zeolite. The ultrasonication conditions were …

Development of broodstock conditioning-, induced spawning-, and hatchery methods for the South African spotted grunter (Pomadasys commersonnii)
… 103 -1 x 10 6 cells/mℓ , and (iii) 0. 125 g/ℓ of bentonite clay. These feeding set-ups were exposed to an overhead illumination of 750 lux and maintained at 21 ± 0.05 °C. Mortality rates were high between one and three DPH, and the survival steeply declined from four to six DPH, irrespective of …

Investigating Bisulfide Sorption onto Bentonite through Laboratory Experiments and Numerical Modelling
… repository (DGR) relies significantly on bentonite clay, a crucial material in the engineered barrier system. One safety concern is microbiologically influenced corrosion of the used fuel containers (UFCs) which may occur if bisulfide (HS-) transports through the bentonite buffer to the …

Assessment of Improvement in Unpaved Roadway Performance Using 3D Geogrids Under Cyclic Loading
… testing program consisted of a lower layer of bentonite clay and sand mix, representing the subgrade material, overlain by an upper layer of aggregate material simulating the base layer. In the reinforced samples, a geogrid layer was positioned between the upper and lower layers to evaluate its …

Analytical Modeling of Bentonite Swelling and Numerical Reactive Transport Modeling in Nuclear Waste Disposal Systems
Bentonite has been widely used as buffer and backfill materials for nuclear waste disposal in last few decades. The main reasons of bentonite being selected for buffer and backfill materials include its low hydraulic permeability and high plasticity, which can restrict the transport of nuclear …
