Mixed-layer chlorite/smectite (corrensite) in ophiolitic rock alteration products

open access: yes, 1996
Corrensite from the Tare Valley (Northern Apennine, Italy) was examined with X-ray powder diffraction (XRD) and high resolution transmission electron microscopy (TEM). XRD showed that the mineral is a well ordered corrensite, i.e.

Improving Micro– and Macro–Algae Speciation Mapping for Management: A Field‐Validated Sentinel‐2 and Sentinel‐3 Intercomparison in the Indian River Lagoon

open access: yesGeoHealth, Volume 10, Issue 10, October 2026.
Abstract In recent years, the health of the Indian River Lagoon (IRL) on Florida's east coast has fluctuated due to recurring harmful algal blooms (HABs). These events typically involve cyanobacteria, dinoflagellates, or A. lagunensis (brown tide) causing water‐quality degradation and seagrass decline.

Décollement Rheology Controls Crustal Deformation on Early Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The circum‐Tharsis wrinkle ridge system represents one of the strongest tectonic imprints of early Mars, formed as the planet's largest volcanic province reshaped the lithosphere and redistributed stresses across thousands of kilometers. The coherent spatial pattern of these ridges suggests deformation governed by a laterally continuous basal ...

Polymer‐clay nanocomposite hydrogels with multiple responses to multiple stimuli

open access: yesResponsive Materials
Hydrogels are widely studied for their stimuli‐responsive properties. They adapt to external stimuli, including physical, chemical and biological ones. To enhance adaptability in complex environments, multi‐responsive hydrogels have been developed, which

A New Experimental Design to Measure Second‐ and Third‐Order Anisotropic Rock‐Stiffness Coefficients Using a Single‐Rock Sample

open access: yesGeophysical Prospecting, Volume 74, Issue 8, October 2026.
ABSTRACT We developed a new experimental setup for measuring and modelling stress‐induced anisotropy and nonlinearity in cylindrical rock samples. Multidirectional ultrasonic velocity measurements were conducted under laboratory conditions and during triaxial‐stress testing to capture dynamic rock properties. This is done by placing endcap transducers (

Adsorption, Aggregation, and Desorption of Proteins on Smectite Particles

open access: yes, 2016
We report on adsorption of lysozyme (LYS), ovalbumin (OVA), or ovotransferrin (OVT) on particles of a synthetic smectite (synthetic layered aluminosilicate).

The Material Basis of 18th‐Century Meissen Porcelain

open access: yesArchaeometry, Volume 68, Issue 5, Page 908-918, October 2026.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

open access: yesBoreas, Volume 55, Issue 4, Page 1208-1227, October 2026.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Duodenal stricture and portal gas accumulation secondary to ulcerative, fibronecrotising duodenitis in a foal

open access: yesEquine Veterinary Education, Volume 38, Issue 10, Page e665-e670, October 2026.
Summary Gastroduodenal ulcer disease with secondary stricture formation of the proximal duodenum and portal gas accumulation is described in a neonatal foal. Conventional diagnostics were performed to reach a diagnosis, including gastroscopy, ultrasonography and positive contrast radiography. In addition, a post‐mortem CT was acquired with the contrast

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

open access: yesJournal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.
