Mechanical Properties and Quantitative Analytical Modelling of Micro/Nanocellulose Co‐Modified Insulating Papers With Different Aspect Ratios

open access: yesHigh Voltage, EarlyView.
ABSTRACT The incorporation of nanocellulose‐doped insulating paper into the material composition of a given structure has been demonstrated to enhance the material’s mechanical properties and retard the development of cracks. However, the effects of different length‐to‐diameter ratios of nanocellulose are different.

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Modelling Patterns of Past Inundation Processes Combining Geoarchaeology and Morphometric Hydrological Analysis in the Shashe‐Limpopo Basin, South Africa

open access: yesArchaeometry, EarlyView.
ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the

The pore space arrangement in podzolic horizons of loamy soils (analysis of 2D AND 3D images)

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2013
A comparative analysis of 2D (in thin sections) and 3D (X-ray CT) images allowed obtaining new data about the pore space arrangement in the EL horizon of soddy podzolic soils.

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

High‐Coverage Nanometric MOx (M = Ir, Rh) Clusters Anchored on Spinel Co3O4 Matrix With Amorphous/Crystalline Heterostructure Harness Efficient Water Electrolysis

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Strong interfacial electronic coupling between nanometric MOx (M = Ir and Rh) clusters and the spinel matrix optimizes the electronic environment and redistributes spatial charge, thereby enabling efficient water electrolysis. Architecting nanometric cluster electrocatalysts with high density of active atoms offers a valuable avenue to simultaneously ...

Sulfated Cyclocarya Paliurus Polysaccharide Sorchestrates the Gut Microbiome to Mobilize a Host‐Derived 12‐HEPE Against Ulcerative Colitis

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
A sulfated polysaccharide (SCP) from Cyclocarya paliurus alleviates ulcerative colitis by reshaping the gut microbiome. This remodeled microbiota orchestrates the upregulation of the host‐derived lipid 12‐HEPE, which directly inhibits the TLR4/NF‐κB pathway to suppress inflammation.

Self‑Protective Carbonized Polymer Dots Enabling Ultralong Room‑Temperature Phosphorescence in Strong and Tough Flexible Gels

open access: yesAggregate, Volume 7, Issue 8, August 2026.
The trade‐off between intersystem crossing and triplet exciton stabilization in PVA‐based self‐protective CPDs is resolved by tuning the alcoholysis degree of PVA. Using PVA with 88% alcoholysis affords NCD88 with an ultralong RTP lifetime of 1.05 s.
