Organophilicization of Bentonite by HDTMA+ and TMPA+ Cations for Sorption of 2,4-Dichlorophenol (2,4-DCP) in Aqueous Solution
Abstract: Bentonite (Bt) was converted to organoclays by intercalation of cationic surfactants into its interlayer space. Two types of organoclays were synthesized from HDTMA and TMPA at 100% CEC, and the adsorbents were characterized by FTIR, XRD and SEM. The adsorption capacities of Bt and the organoclays for the removal of 2,4-dichlorophrnol (2,4-DCP) from aqueous solutions were tested under different conditions. Two adsorption isotherm models (Langmuir and Freundlich isotherms) were used …

A Comprehensive Review on Ethnomedicinal Uses of Fishes in Asia
Abstract: In Asia, fish hold a multifaceted role as crucial dietary and economic resources, cultural symbols, and traditional ethnomedicine remedies. With over 4,000 known freshwater and marine fish species in Asian waters, these aquatic creatures feature prominently in the region's diverse ethnomedical traditions. The continent's numerous ethnic groups, each with unique indigenous medical practices, often rely on traditional ethnomedicine due to limited access to modern allopathic healthcare. The paper delves into …

Analysis and Design of Cantilevered Steel False Work Systems Subjected to Earthquake Loads
Abstract: Construction of buildings with non-typical floors has been always problematic in extending the false work all over the height to support non-regular cantilevered slabs extending from upper floors. Cantilevered frames supporting formwork systems with no need for extending the false work along the height of the building have been recently designed in previous studies. However, the need to design such cantilevers in order to withstand dynamic loads has emerged. Within …
