Performance of cross-linked chitosan-zeolite composite adsorbent for removal of Pb2+ ions from aqueous solutions: Experimental and Monte Carlo simulations studies
(Elsevier, 2023/12/1)
In this study, we investigated the performance of a cross-linked chitosan (Ch)-zeolite (Z) composite (Ch-Z) adsorbent for the removal of Pb2+ ions from water. The results revealed that the Ch-Z composite exhibited excellent ...
A comparative review of the adsorption and photocatalytic degradation of tetracycline in aquatic environment by g-C3N4-based materials
(Elsevier, 2023/10/1)
In recent times, graphitic carbon nitride (g-C3N4)-based materials (Ms) have emerged as promising adsorbents and photocatalysts to remove tetracycline (TC) from water. This review article offers a comprehensive outline of ...
Microstructure and wear analysis of CoWC alloy layers deposited by PTA process
(EDP SCIENCES S A17, AVE DU HOGGAR, PA COURTABOEUF, BP 112, F-91944 LES ULIS CEDEX A, FRANCE, 12 April 2)
CoWC composite coatings were produced on AISI 430 steel by the plasma transfer arc cladding. Three different powder mixtures containing WC (90%, 85% and 80%) and Co (10%, 15% and 20%) were used. Phase composition, ...

(WALTER DE GRUYTER GMBHGENTHINER STRASSE 13, D-10785 BERLIN, GERMANY, 8 March 20)
The effect of Fe, P and Mn on microstructure and fatigue properties of CuZnSn bronzes investigated with
optical microscopy and scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, hardness, ...
Austempering Ce-La inoculated solution strengthened ferritic ductile cast irons
(REDAKCIA KOVOVE MATERIALYUL RACIANSKA 75, PO BOX 95, 830 08 BRATISLAVA 38, SLOVAKIA, 01 Februar)
The influence of austempering conditions on the microstructure, hardness, tensile strength, and impact toughness of Ce-La inoculated solution-strengthened ferritic ductile irons was analyzed. The austempering was performed ...
Removal of methylene blue dye from aqueous solution using pure talc and polyacrylamide–talc composite: Isotherms, kinetic and thermodynamic studies
(Springer Berlin Heidelberg, 2023/10)
In this study, the composite of talc (as a natural mineral) and polyacrylamide (an inert polymer) was synthesized and the adsorption properties of the new material were examined for methylene blue (MB) in an aquatic medium. ...
Prunus mahaleb shell as a sustainable bioresource for carminic acid removal from aqueous solution: Experimental and theoretical studies
(Elsevier, 2023/3/5)
This study focused on the performance of Prunus mahaleb shell (MS) agricultural waste, which is used as
an alternative biosorbent for carminic acid (CA) removal from aqueous solution. The effects of different
parameters ...
Some Classification Theorems and Endomorphisms in New Classes
(MDPI, 2023)
Let ℧ be a prime ring of char(℧) not equal 2 with its center Z. This article introduces new classes of endomorphisms and investigates how they relate to antiautomorphisms of prime rings and the commutativity of prime rings. ...
Toxoplasma gondii and multiple sclerosis: a population-based case-control seroprevalence study, Central Anatolia, Turkey
(2023)
Background: Toxoplasma gondii, an obligate intracellular parasite, is prevalent in various mammalian species, as
well as certain avian, reptilian, and cold-blooded organisms. While immunocompetent individuals generally
remain ...
Automatic Detection and Mapping of Dolines Using U-Net Model from Orthophoto Images
(2023)
A doline is a natural closed depression formed as a result of karstification, and it is the most common landform in karst areas. These depressions damage many living areas and various engineering structures, and this type ...
