Fabrication of pore-filling cation-exchange membrane from waste polystyrene and Spunbond Meltblown Spunbond (SMS) non-woven polypropylene fabric as the substrate.

Commercial ion-exchange membranes are typically thick, possessing limited mechanical strength, and have relatively high fabrication costs. In this study, we utilize a three-layer polypropylene fabric known as Spunbond Meltblown Spunbond (SMS) as the substrate. This choice ensures that the resulting membrane exhibits high strength and low thickness.

The swelling performance of raw and modified bentonite of geosynthetic clay liner as the leachate barrier exposed to the synthetic E-waste leachate.

Heavy metals are prevalent in electrical and electronic waste. The sealing of this type of waste disposal site is critical due to the existence of toxic materials. In this regard, Geosynthetic Clay Liners (GCLs) are widely used as one of the most common engineered barriers at disposal sites.

Prolonged semen incubation alters the biological characteristics of human spermatozoa.

Objective: The present study assessed the biological characteristics of human spermatozoa at different time intervals (0, 1, 1.5, and 2 hours) after incubation at 37°C.

Methods: Twenty-five normozoospermic semen samples were incubated at 37°C.

Research trends on ash stabilization in the pavement during 2002-2021.

Incineration ash stabilization in the pavement is an effective approach to reduce environmental impact and proper disposal. This study aimed to achieve a bibliometric analysis of "ash stabilization in pavement" research during 2002-2021, considering language, chronological trends, source types, subject areas, document types, affiliations, journals, countries, and author keywords. Also, social network analysis (SNA) was used for trends mapping and global collaboration determination among countries.

A bibliometric analysis of research trends in life cycle assessment of fresh concrete and mortar during 1997-2021.

The construction industry relies heavily on concrete as a fundamental material. According to the shift towards environmental sustainability in recent years, studies on life cycle assessment (LCA) of concrete and mortar and reducing their environmental impacts have increased significantly. This paper provides insights into studies performed in LCA of fresh concrete and mortar until 2021 by using a bibliometric method.
