In vitro cytocompatibility evaluation of nanostarch reinforced polyaniline-polyvinyl alcohol conductive bionanocomposites for skin tissue engineering application
Springer Science and Business Media LLC - Tập 9 - Trang 252-259 - 2023
In this study, we aimed to fabricate nanostarch (NS) reinforced polyaniline/polyvinyl alcohol (PANI-PVA) bionanocomposite of polyaniline-polyvinyl alcohol-nanostarch for skin tissue engineering application. The microstructure of the bionanocomposite was analyzed using TEM and the particle size ranged from 35 to 37 nm. The swelling degree was increased with the increase in the concentration of nano......
Clay-based materials for enhanced water treatment: adsorption mechanisms, challenges, and future directions
Springer Science and Business Media LLC - - 2023
Water treatment is of paramount importance to ensure the availability of clean and safe drinking water. In recent years, clay-based materials have gained significant attention as promising adsorbents for water treatment applications. This review provides a comprehensive analysis of different clay types and their surface adsorption properties for water treatment. This review begins by introducing t......
Application of geothermometric and hydrochemical methods to the investigation of thermal water of sources in the Northeastern of Algeria case of Setif city
Springer Science and Business Media LLC - Tập 8 - Trang 69-78 - 2022
Thermal water in northeastern Algeria (Setif) is a promising, sustainable resource of energy. To date, thermal water has not been used as a source of renewable energy in Algeria as no clear strategy has yet been developed for its use. In this study, eight samples of thermal water springs distributed within the area of Setif city were assessed, and their physical and chemical parameters (such as te......

Certain results associated with mixed integral equations and their comparison via numerical methodsAbstract In this article, we consider existence and unique of solutions of linear mixed integral equations of third, second and first kinds. Then, we use the collection method to discuss numerical solutions by employing Chebyshev and Legendre polynomials. To support our results, we use Mable 18 to compute errors in all existing cases.

Utilization of cloud point extraction for enhancement the efficiency of spectrophotometric estimation of milnacipran HCl as anti-depression drug in dosage forms and application to its tablets uniformity testing
Springer Science and Business Media LLC - Tập 9 - Trang 29-39 - 2022
Two spectrophotometric techniques that are straightforward, sensitive, accurate, and precise have been created and validated for the detection of a particular antidepressant drug, milnacipran HCl (MCN), in both pure and dosage forms. The method A was based on the reaction of MCN with p-dimethylaminobenzaldehyde (p-DMAB) in an acidic medium, to give a yellow colored Schiff’s base product that can b......
Foraminifera dissolution phases in the upper cretaceous succession of Jebel Duwi, Egypt
Springer Science and Business Media LLC - Tập 9 - Trang 185-203 - 2023
The present work examines the function of differential dissolution in planktic and benthic foraminifera and introduces the major factors that affect dissolution in early Mid-Maastrichtian Event MME and Late Maastrichtian Event LME paleoenvironmental reconstructions. Two observations on foraminifera dissolution in the Dakhla Formation, where planktic foraminifera are more susceptible to dissolution......
Upper Paleocene–lower Eocene calcareous nannofossil biostratigraphy at Nukhul, West Central Sinai, EgyptAbstract This research offers a comprehensive examination of calcareous nannofossils, isotopic ratios (δ18 O and δ13 C), and carbonate content spanning the critical Paleocene-Eocene transition at Gebel Nukhul. The study covers three lithostratigraphic formations: Tarawan, Esna, and Thebes. By meticulous analysis, we’ve identif... ...

Foraminifera study for the characterization of the Campanian/Maastrichtian boundary in Gebel Owaina, Nile Valley, Egypt
Springer Science and Business Media LLC - Tập 9 - Trang 341-359 - 2023
The present work aims to provide a high-resolution stratigraphic range of the planktic foraminiferal group during the Campanian/Maastrichtian boundary (C/M) of Gebel Owaina, Nile Valley. We use the base of Planoglobulina acervulinoides (CF7c Subzone) to mark the C/M boundary, where the planktic foraminiferal assemblages in the subzone are proposed as indicative of the early Maastrichtian age. Five......
