Conventionally, silver nanoparticles (AgNPs) have been prepared by using either physical methods such as electron beamand photo-reductions or chemical methods with various reducing agents and organic stabilizers. Many researches have been conducted previously in the following areas: tailoring of particle size, polydispersity, geometric shape, and nucleation. Low-molecular-weight surfactants or ...

-The effect of ethylene oxide-sterilization on homoionic (Na +, K § Ca 2+, Cu 2+, A1 s+, and Fe 3+) montmorillonite samples was examined. The results indicate that ethylene oxide polymerized to polyethylene glycol in the interlayer of Cu 2+-, AP +-, and FeS+-saturated clays, as substantiated by the increase in the d(001) values, as well as by the decrease in the cation-exchange capacity after r...

Introdouction: Fibrous dysplasia is a benign fibro-osseous lesion that affects craniofacial bones including the maxilla and mandible. In the most cases of fibrous dysplasia of facial bones, radiographic findings represent lucent or mixed radiolucent-radiopaque lesion with ill-defined borders and gradual blending of its border with adjacent bone . In this presentation, a patient suffering ...

In this research, behaviour of clayey soils under triaxial loading is studied using Neural Network. The models have been prepared to predict the stress-strain behaviour of remolded clays under undrained condition. The advantage of the model developed is that simple parameters such as physical characteristics of soils like water content, fine content, Atterberg limits and so on, are used to mode...

Clay, as a rock term, describes a soft, loose, earthy material containing particles with an average grain size of less than than 0.004 mm (4 mm) in the Wentworth grain size scale and less than 0.002 mm (2 mm) in most soil investigations. Clay is composed mostly of clay minerals, but may also contain quartz, feldspar, carbonates, ferruginous material, and other non-clay materials. All clays, apa...

The soil mantle in Namaqualand is immature in terms of weathering. Despite or even because of this, the diversity and spatial variability of soil physical and chemical properties is exceptionally high and could be fundamental in governing biodiversity and ecosystem function. In arid landscapes, the way the soil sheds, admits, stores, diverts and transmits water is crucially important. Namaquala...

it is sometimes difficult to recognize a jaw lesion as osteosarcoma, ossifying fibroma or ‎fibrous dysplasia in routine hematoxylin and ‎eosin staining and a more accurate technique is needed to differentiate these ‎lesions. ‎many studies have shown the potential usefulness of silver-stained nucleolar organizer region (agnor) parameters for the diagnosis of various neoplasms. this study was car...

Herein, magnetite nanoparticles (MNPs) synthesized from altered basalt were used to develop a composite with H2O2–activated bentonite (BE) and fibrous sawdust (SD). The as-prepared BE/SD–MNPs characterized by FTIR, FESEM, TEM, TGA, DSC, Zeta potential techniques utilized as an effective multifunctional for removing methylene blue (MB). adsorption isotherms of MB at 25–55 °C analyzed via kinetic...
