Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

open access: yesPest Management Science, Volume 82, Issue 8, Page 7746-7757, August 2026.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

Ceramic Production and Geodiversity in Iron Age Iberia: An Archaeometric Study of Pottery from Castrejón de Capote (SW Spain)

open access: yesArchaeometry, Volume 68, Issue 4, Page 659-673, August 2026.
ABSTRACT The hillfort of Castrejón de Capote is one of the best investigated settlements of Late Iron Age southwest Iberia. Located in the territory that the classical sources attributed to the Celtici, it was occupied between the early 4th and the 1st centuries bce.

Influence of Organo-Clay on Mechanical and Thermal Properties of O-Muscovite/PP Layered Silicate Nanocomposite [PDF]

open access: yes, 2011
O-Muscovite/PP Layered Silicate Nanocomposites were prepared via melt compounding using different filler content. Muscovite was organomodified with Cetyldimethylethylammonium bromide (CEDAB). The thermal and mechanical properties of nanocomposites, based

Palatal violence: Sonic gatekeeping and enemy‐making in wartime Ukraine

open access: yesJournal of Linguistic Anthropology, Volume 36, Issue 2, August 2026.
Abstract Within 2 days of Russia's full‐scale invasion of Ukraine, a single word—palianytsia, a Ukrainian round loaf—became a phonetic test separating Ukrainians from Russians. The article traces how a culinary term was enregistered as a wartime shibboleth that structurally marks the very citizens it was meant to protect as enemies.

Ductile Extrusion Triggered by Continental Collision in NE Brazil

open access: yesTerra Nova, Volume 38, Issue 4, Page 266-277, August 2026.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.

Ammonium quantification in muscovite by infrared spectroscopy [PDF]

open access: yes, 2003
International audienceSingle muscovite grains of different chemical composition (in particular Si-content from 3.05 to 3.69 per formulae unit (pfu)) and origin (metamorphic and granitic rocks) were analysed by infrared (IR) spectroscopy.

Emergence of Continents Stabilized the Bioavailability of Boron

open access: yesTerra Nova, Volume 38, Issue 4, Page 278-284, August 2026.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.
