Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

Polymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Influence of calcination temperature on the durability of metakaolin concrete and limitations of conventional testing methods

Structural Concrete, EarlyView.
Abstract Incorporating metakaolin (MK) as a partial cement replacement offers a viable pathway to reduce carbon emissions while improving concrete performance. However, its durability behavior remains inconsistent, and the applicability of durability test methods to MK‐based concrete is not well established.

Degradation of Dye C.I. Reactive Red 15 in Aqueous Solution by Kaolinite Supported Zero Valent Iron [PDF]

Nature Environment and Pollution Technology, 2019
Dyes are important source of water pollution and their degradation products may be carcinogens and toxic to mammals. For evaluation of oxidative degradation of dye wastewater, the kaolinite supported zero valent iron were synthesized.

AES‐Debye: an accurate, efficient and scalable engine for Debye scattering calculations

Journal of Applied Crystallography, EarlyView.
AES‐Debye is an accurate, efficient and scalable engine for evaluating the Debye scattering equation that enables total scattering calculations for large atomistic models. Corrected pair‐distance binning and numerically robust accumulation suppress discretization artifacts, while parallel CPU/GPU execution enables efficient computation of scattering ...

Adsorption Characteristics of Bixin on Acid- and Alkali-Treated Kaolinite in Aprotic Solvents

Bioinorganic Chemistry and Applications, 2018
The adsorption of bixin in aprotic solvents onto acid- and alkali-treated kaolinite was investigated. Kaolinite was treated three times, for 6 h each, with 8 M HCl or 5 M KOH. The adsorbents were characterized by XRD, FT-IR, EDS, and BET-N2.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Ceramic Raw Materials and Technological Choices in Iron Age Tyre (Lebanon): A Multiproxy, Fabric‐Based Approach

Archaeometry, EarlyView.
ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...
