Ordering of tetrahedral and octahedral layers in synthetic lepidolites and Li-muscovites: two-dimensional {1H} → 29Si ∕ 27Al CPMAS HETCOR and {19F} → 29Si ∕ 27Al CPMAS HETCOR spectroscopy [PDF]

open access: yesEuropean Journal of Mineralogy
Cationic ordering in the octahedral and tetrahedral sheets of synthetic lepidolites with composition K(LixAl3−x)[Si2xAl4−2xO10](OH)yF2−y and Li-muscovites with K(LixAl2-x/3□1-2x/3)[Si3AlO10](OH)yF2−y has been investigated using two-dimensional (2-D) {1H ...

Ba[C(CN)3]2 and Pb[C(CN)3]2: Two Remarkably Different Heavy Main‐Group Metal Bistricyanomethanides

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 8, 25 May 2026.
Metathesis reactions of either barium dichloride, BaCl2, or lead dichloride, PbCl2, respectively, with Ag[C(CN)3] in water yielded single crystals of anhydrous Ba[C(CN)3]2 and Pb[C(CN)3]2. Ba[C(CN)3]2 crystallizes in the monoclinic space group P21/n (no. 14) with the lattice parameters a = 437.98(3) pm, b = 1685.36(11) pm, c = 1398.87(9) pm, β = 96.541(

MRMinerals and MineralTD: Machine‐Readable Mineral Formula and Compositions Data Set for Data‐Driven Research

open access: yesGeoscience Data Journal
Artificial intelligence (AI) is being increasingly applied in the geosciences, particularly in fields like mineralogy, where it supports tasks such as mineral classification, automated thin‐section image analysis, or mineral exploration targeting.

Fluctuations and differential contraction during regeneration of Hydra vulgaris tissue toroids

open access: yesNew Journal of Physics, 2013
We studied regenerating bilayered tissue toroids dissected from Hydra vulgaris polyps and relate our macroscopic observations to the dynamics of force-generating mesoscopic cytoskeletal structures.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 864-911, April 2026.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Twenty‐Three Years of Landslide Activity in the European Alps–Part 2: Investigating Triggers and the Impacts of Meteorological Change on Landslide Occurrences

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Landslides represent one of the most devastating natural hazards in mountainous regions, posing significant threats to human safety, infrastructure and ecosystems. It is well established that there is a connection between meteorological factors and landslide occurrences but the mechanisms of these interactions and the impacts of climatic ...

Active Plume, Abandoned Ridge, or Ancient Slab? olivine‐Hosted Melt Inclusions Record the Mantle Melting Conditions Below the East Pacific Revillagigedo Archipelago, Mexico

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The voluminous active volcanoes of the Revillagigedo Islands of Socorro and San Benedicto in the east Pacific Ocean exhibit hotspot geochemistry. However, the presence of a deep mantle plume has not been seismologically confirmed. Instead, a fossil subducted slab is identified in the lower mantle underneath the volcanoes. Moreover, the islands

On New Alkaline Sulfatometallates: Cs6[(WO2)2O(SO4)4], K8[(MoO2)2(SO4)6], K7.9Sr0.1[(WO2)2(SO4)6] and Na4[MoO2(SO4)3]

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 4, 17 March 2026.
Two new alkaline sulfatometallates show promising optical absorption, emission and even non‐linear optical properties together with an astonishingly high thermal stability. The new sulfatotungstate Cs6[(WO2)2O(SO4)4] exhibits a hitherto unknown anion with an unusual W–O–W angle of 180° and edge‐sharing WO6 and SO4 polyhedra.

Initiation of the Ferrar Large Igneous Province Started in Southern North Victoria Land, Antarctica, With Shallow Emplacement of Sills Causing Magma‐Soft‐Rock Interaction and Phreatomagmatic Eruptions

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Early Jurassic volcanism was in the southern north Victoria Land portion of the Ferrar Large Igneous Province preceded by multiple phases of shallow‐level intrusions of Ferrar sills into the 300 m thick cover of sedimentary rocks of the Triassic‐Jurassic Victoria Group.
