Adsorption of Methyl Orange on a Novel Palygorskite/UiO-66 Nanocomposite

Applied Sciences, 2022
Herein, a novel composite material containing UiO-66 and palygorskite (Pal) clay mineral was prepared using a facile one-pot synthesis process. The material was studied using a variety of techniques and applied as did not affect the structure of the ...

Characteristics of Immersion Freezing Ice Nucleating Particles During Dust Season in Beijing

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Atmospheric dust is a primary source of ice nucleating particles (INPs), yet their concentrations at temperatures warmer than −20°C are not fully characterized during Asian dust events. This study uses a membrane filtering method to collect aerosol samples and a droplet freezing method to measure daily immersion‐mode INP concentrations in ...

Recent Zeolite Modifications in Bifunctional Catalysts for Carbon Dioxide Hydrogenation to Aromatics: A Minireview†

Chinese Journal of Chemistry, Volume 44, Issue 17, Page 2933-2949, 1 September 2026.
Thermocatalytic hydrogenation of CO2 to aromatic hydrocarbons represents a sustainable route for high‐value CO2 utilization. Bifunctional catalysts combining metal/metal oxide components with acidic zeolites enable the direct synthesis of BTX aromatics.

Sepiolite-palygorskite from the Hekimhan region (Turkey)

, 1995
Upper Cretaceous-Tertiary marine clayey-calcareous rocks of the Hekimhan basin contain fibrous clay minerals in significant amounts. Ophiolitic rocks in the provenance area have contributed the elements to form the clay minerals.

Formation and Alteration of Magnesite Nodules From Kunwarara, Queensland, Australia, as an Analog to Mg‐Carbonate Formation on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Magnesite (MgCO3) is a magnesium (Mg) carbonate mineral that records the aqueous environmental conditions of its formation. On Earth, magnesite forms in metamorphic, diagenetic or pedogenic environments, and distinguishing between these environments is critical for understanding the fluid chemistry during magnesite precipitation. Mg carbonates

Fossils as cultural heritage: Scientific, commercial and legislative issues

Geology Today, Volume 42, Issue 5, Page 263-272, September/October 2026.
Fossils are among the principal sources for understanding the history of life through ‘Deep Time’ and can inform projections of biotic responses to environmental change. Despite a widespread recognition of the scientific, historical and communication significance of fossils in our culture, their role as part of our cultural heritage is still far from ...

Purification of Sepiolite and Palygorskite.

Journal of Society of Materials Engineering for Resources of Japan, 1995
Methods of purifying sepiolite-paygorskite series were reviewed and discussed under the two purification categories: extraction of elements and elimination of minerals.A number of previous works focused on the extraction of elements from sepiolite by acid treatment because knowledge gained from basic studies on dissolution kinetics, structural ...

Long‐Distance Aeolian Dust Deposited on the Island of Crete (Greece): Detection, Characterization, and Provenance

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Long‐distance aeolian dust transport represents one of the largest sediment fluxes on Earth, with North Africa being a dominant source. The island of Crete in the Eastern Mediterranean lies within major transport pathways but remains underexplored regarding multi‐proxy fingerprinting of deposited dust.
