Enhancing reactivity in muscovitic clays: Mechanical activation as a sustainable alternative to thermal activation for cement production Appl. Clay. Sci. (IF 5.6) Pub Date : 2024-01-24 Jofre Mañosa, Adrian Alvarez-Coscojuela, Josep Marco-Gibert, Alex Maldonado-Alameda, Josep Maria Chimenos
The use of calcined clays in the construction industry is thriving. However, muscovitic or illitic clays, which constitute a large portion of the available clay resources, are hardly activated by thermal processes. This work aims to enhance the reactivity of raw muscovitic clay through mechanical activation. Various combinations of milling time and rotation speed were evaluated. The results confirmed

Amine-modified halloysite nanotube embedded PEI cryogels as adsorbent nanoarchitectonics for recovery of valuable phenolic compounds from olive mill wastewater Appl. Clay. Sci. (IF 5.6) Pub Date : 2024-01-22 Sahin Demirci, Selin Sagbas Suner, Selehattin Yilmaz, Sema Bagdat, Feyzullah Tokay, Nurettin Sahiner
Here, natural tubular clays, halloysite nanotubes (Hal), were modified with ethylenediamine (EDA), triethylenetetramine (TETA), pentaethylenehexamine (PEHA), and polyethyleneimine (PEI) to enhance their adsorption capabilities for phenolic compound for the treatment of olive mill wastewater (OMWW). Among the modified Hal adsorbents, Hall-PEHA adsorbent demonstrated a higher surface charge of +15.9

Physicochemical controls on desiccation crack patterns in bentonite: A comprehensive examination of salinity effects Appl. Clay. Sci. (IF 5.6) Pub Date : 2024-01-18 Xin Wei, Shiyu Ren, Dianrun Yang, Zhonghao Sun, Ling Xu
Climate-related extreme weather events such as drought and heat waves increase regional soil salinization and desiccation cracking that degrade the environment. Soils shrink, crack, and accumulate salts during desiccation. However, the effect of salt concentration on the characteristics of desiccation crack is not well understood. Previous experimental observations and explanations for cracking characteristics

The role of clay minerals in the concentration and distribution of critical metals in lateritic palaeosols from NE Iberia Appl. Clay. Sci. (IF 5.6) Pub Date : 2024-01-19 Elisa Laita, Blanca Bauluz, Alfonso Yuste
The intense chemical weathering processes that lead to the formation of laterites and bauxites result in the enrichment of critical metals (Sc, V, Co, Ga, Ge, Nb, In, Hf, Ta, W, and REEs), which are of great economic interest and are directly involved in the manufacture of various devices essential for the technology transition. This work focuses on combined geochemical and scanning transmission electron

Green synthesis of layered double hydroxides (LDH) for the remediation of As and Cd in water and soil Appl. Clay. Sci. (IF 5.6) Pub Date : 2024-01-20 Xuanru Li, Liuwei Wang, Bei Chen, Yuanyuan Xu, Huixia Wang, Fei Jin, Zhengtao Shen, Deyi Hou
Layered double hydroxides (LDH) show great promise for the remediation of heavy metals and metalloids in aqueous media and soils. In this study, we propose a green synthesis approach for LDH utilizing industrial waste granulated ground blast furnace slag (GGBS) and readily available magnesium oxide (MgO), and applied these green synthesized LDH for As and Cd remediation in both water and soil.
