Features of bleaching cottonseed oil with local adsorbents [PDF]

E3S Web of Conferences
The article presents research data on the process of adsorption refining (bleaching) of cottonseed oil, which differs from other vegetable oils in its complex composition and the presence of gossypol.

Experimental studies with palygorskite dusts. [PDF]

Occupational and Environmental Medicine, 1987
As the preliminary results of experimental studies on dust from the palygorskite group have led to some confusion a detailed description of the completed investigation is given for clarification. As in other experiments the biological effects have been shown to be associated with the physical characteristics of the fibres in these specimens. Samples of

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, Volume 73, Issue 5, Page 1892-1910, August 2026.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

The Magnetic Mineralogy of Carbonaceous Chondrites: A Microscopy and Machine Learning Study of Meteorite WIS 91600

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...

Improvement of CO2 capture performance of calcium-based absorbent modified with palygorskite

, 2016
Limestone can be used for CO2 capture and sequestration (CCS) in flue gas effectively. However, its CCS capability will dramatically decline after several cycles due to the surface "sintering".

The Occurrence and Morphology of Naturally Occurring Respirable Mordenite Mineral Fibres in New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Mordenite is a naturally occurring zeolite mineral that is the seventh most common zeolite mineral globally, forming at low temperatures (≥100°C) in hydrothermal systems. In New Zealand, extensive deposits of mordenite are commonly associated with areas of hydrothermal alteration, particularly in the Coromandel and Taupo Volcanic Zones.

Occurrence of Palygorskite and the Major Soil Properties Influencing its Distribution in Selected Soils of Bushehr Province [PDF]

علوم آب و خاک
Although several reports are available on the distribution of Palygorskite in the soils of arid regions of Iran, there is not much information about the presence and abundance of this important fibrous clay mineral in the soils of Bushehr Province.

A New Application for Salted Water-Based Fluids with Palygorskite: Formulation Designing for Temporary Plug and Abandonment Operations of Petroleum Wells

Applied Sciences
Palygorskite has shown satisfactory performance in salted water-based fluids, especially as a rheological agent. However, this type of formulation has been used in the petroleum industry only in well drilling operations.

From spent dye-loaded palygorskite to a multifunctional palygorskite/carbon/Ag nanocomposite

RSC Advances, 2016
Palygorskite (PAL) has been widely used for adsorption removal of dyes from wastewater, but the dye-loaded PAL is usually discharged as solid waste because it is hardly regeneratable by conventional elution processes.

Octahedral cation distribution in palygorskite [PDF]

American Mineralogist, 2009
The OH speciation of 18 palygorskite samples from various localities were evaluated by near infrared spectroscopy (NIR) and compared to the corresponding octahedral composition derived from independent, single-particle analytical electron microscopy (AEM).
