Bitumen Emulsion—Mineral Surface Interactions: An NMR Study on the Interface Layer Composition

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 2, Page 170-178, February 2026.
We describe a 1H NMR approach to study the interface layer formed by a specified bitumen emulsion in the presence of non‐magnetic as well as magnetic minerals. This approach is based on the consecutive flushing off “bulky” components of the bitumen emulsion and the following extraction of the surface layer material, which can then be analyzed by NMR ...

Cave depth and subterranean connectivity are drivers of intraspecific trait variability in two subterranean congeneric beetles

open access: yesEcological Entomology, Volume 51, Issue 1, Page 153-164, February 2026.
The abundance of cave beetles increases with depth, with Duvalius hartigi exhibiting maximum densities at greater depths in volcanic systems. Troglomorphic traits become more pronounced with increasing depth exclusively in the alpine species Duvalius carantii.

Low‐Frequency Polarization of Blank Ice Features in Solid Rocks

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract For hydrogeological management of seasonally frozen soils, or permafrost, the quantification of ice and water content is key. Changes in electrical conductivity are commonly used to monitor ice‐to‐water ratios but hard rocks, ice and air are all highly resistive materials.

How the small host the small: cryptogam trait‐mediated structuring of Antarctic microarthropod communities

open access: yesEcography, Volume 2026, Issue 1, January 2026.
Primary producers shape terrestrial biodiversity, but most research has focused on vascular plants, while the role of cryptogams (mosses, lichens and algae) remains under‐explored. Cryptogams dominate Antarctic vegetation and support diverse microarthropod communities. However, how cryptogam traits influence these communities remains poorly understood.

Regional variation in the Amitsoq gneisses related to crustal levels during late Archean granulite facies metamorphism: Southern west Greenland [PDF]

open access: yes
The dominant lithology at Kangimut sangmissoq is described as nebulitic tonalitic gneiss containing highly distended plagioclase phyric amphibolites. The gneiss amphibolite complex was intruded by Nuk gneiss between 3.05 and 2.90 Ga and later (2.6 to 2.7

Skin and soft tissue modeling and its impact on apparel modeling

open access: yesCommunications in Development and Assembling of Textile Products, 2023
Rigid body avatars do not fully define the complex interaction between human and body-worn product (humanoid-to-coveroid).  Skin and soft tissue modeling to create more realistic 3D humanoid body models are needed.

Species richness, composition, and dominance of core and climate relicts of African miombo woodlands

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract The miombo woodlands, which span about 10% of the African continent, are essential for the ecosystem services they provide. These woodlands are mainly dominated by the genera Julbernardia, Isoberlinia, and Brachystegia. However, there is limited understanding of how species dominance and richness change in relict sites, which are far removed ...
