Evolution of Crematogaster sordidula (Hymenoptera, Formicidae) Ants in the Mediterranean Region During Plio‐Pleistocene Climatic Changes

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 615-638, July 2026.
ABSTRACT Understanding insect responses to global climate change involves identifying strategies used during past climate oscillations. Phylogeography offers a powerful framework to unravel how historical climatic and geological events have shaped the spatial genetic patterns of species, providing critical insights into evolutionary processes, whereas ...

Phylogeny and Species Delimitation in the Land Snail Genus Chilostoma (Gastropoda: Helicidae) and East–West Alpine Disjunctions

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 589-601, July 2026.
ABSTRACT Chilostoma includes large, mostly rock‐dwelling snail species, widespread in the European Alps and the Apennines in Italy. We analysed the phylogenetic relationships and the species delimitation of the Chilostoma (Chilostoma) species based on genomic ddRAD loci. The Chilostoma (Chilostoma) taxa form three sister pairs. Chilostoma achates and C.

Influence of an Oxygen‐Free Atmosphere on Diamond‐Single‐Grain Scratching of Ti–6Al–4V

open access: yesAdvanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
Single‐grain scratching of Ti–6Al–4V is investigated under controlled, oxygen‐free, and ambient atmospheres using a novel experimental setup with in situ high‐speed imaging. The approach enables direct observation of chip formation and adhesion under suppressed oxidation.

Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials

open access: yesAdvanced Materials, Volume 38, Issue 31, 2 June 2026.
Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

Liquids as Reinforcements for Anisotropic and Tough Soft Matter Composites

open access: yesAdvanced Materials, Volume 38, Issue 33, 12 June 2026.
Liquid metal droplets are shaped and oriented within soft elastomers to create all‐soft matter composites with programmable mechanical anisotropy. These liquid inclusions act as fiber‐like reinforcements, enabling directional stiffness, enhanced toughness, and controlled crack steering under extreme deformation, offering new routes to resilient soft ...

Analysis on inverse method for design parameters of involute spur gears with unilateral tooth profile wear

open access: yesJixie chuandong
ObjectiveThe failure of transmission gears in imported and aged equipment due to tooth flank wear often leads to premature scrapping of the entire machine, as original design data is frequently unavailable for repair or replacement. To address this issue,

Non‐Continuous Iridescent Variable Structural Color Based on Metallic Surface Periodic Structures

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
This study presents an ink‐free laser nanofabrication technique that generates periodic arched microstructures on titanium surfaces, achieving non‐continuous iridescent dual‐color switching. The ridge and side flanks of these structures possess distinct oxide film thicknesses, enabling angle‐dependent selective reflection of specific wavelengths.

Schottky Barrier Engineering in n‐Type Organic Source‐Gated Transistors Enabling High Conductance

open access: yesAdvanced Materials Technologies, Volume 11, Issue 11, 5 June 2026.
This study introduces a modified source electrode architecture for n‐type organic source‐gated transistors (OSGTs). By integrating Schottky and Ohmic contact regions, the design achieves a thinner depletion envelope, enhancing mobility nearly tenfold and reducing threshold voltage.
