Molecular mechanisms for the adhesion of chitin and chitosan to montmorillonite clay

Molecular dynamics simulations have been performed to investigate molecular adhesion of chitin and chitosan oligomers to montmorillonite (Mnt) clay at different degrees of acetylation (DA, 0%, 20%, 40%, 60%, 80% and 100%) and different degree of ...

Oligomerization of Non‐Activated Nucleotides Under Hot Acidic Wet–Dry Cycling Without Catalytic Agents

ChemSystemsChem, Volume 8, Issue 4, July 2026.
Oligonucleotides form spontaneously through hot wet‐dry cycling of pure non‐activated nucleotides. No catalytic agents were added, and pH was naturally buffered by the nucleotides. Oligonucleotide formation was confirmed and quantified using mass spectrometry, spectroscopy and electrophoresis, establishing a solid baseline for the intrinsic extent of ...

Utilization of Thermally Modified Water Treatment Plant Sludge as an Adsorbent for Fluoride Removal

Environmental Quality Management, Volume 36, Issue 1, July 2026.
ABSTRACT The presence of fluoride (F−) at high concentrations in drinking water is a global concern due to its adverse health effects. This study evaluated the removal of F− ions by adsorption using an adsorbent produced from thermally modified water treatment plant sludge (TWTPS), providing an efficient and low‐cost alternative for contaminated water ...

Hyperspectral Fingerprinting of Dune Sediments Across the Arabian Peninsula: Insights Into Sediment Provenance and Transport Pathways From NASA's EMIT Data

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Arabian Peninsula encompasses one of the world's most extensive aeolian systems, yet the provenance and transport history of its dune sediments are not well understood. Using hyperspectral data from NASA's Earth Surface Mineral Dust Source Investigation (EMIT), we mapped mineral compositions and abundance patterns across dune fields and ...

Comparison of Soil Mineralogy From EMIT Imaging Spectroscopy and Ground‐Based Measurements in the Deserts of Southern California

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract The highly variable spatial composition of desert soils remains a major source of uncertainty in estimates of dust radiative forcing. Existing soil mineralogy data sets used in climate models are limited by sparse ground observations and coarse spatial resolution.
