PLESIOSAURS (DIAPSIDA, SAUROPTERYGIA) FROM LATE CRETACEOUS (LATE CAMPANIAN–EARLY MAASTRICHTIAN) MARGINAL MARINE ENVIRONMENTS FROM NORTH PATAGONIA

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
During the late Campanian and early Maastrichtian, Northern Patagonia suffered the first stage of the Atlantic marine ingression that reached the Neuquén Basin. The Allen and La Colonia formations show the early stages of this change, and were deposited

Agate Fossil Beds

open access: yes, 1980
What was life like in North America 21 million years ago? Agate Fossil Beds provides a glimpse of that time, long before the arrival of man, when now-extinct creatures roamed the land which we know today as Nebraska.

Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

CENOZOIC (PRE-PLIOCENE) PALEOENVIRONMENTAL TRENDS BASED ON PALYNOMORPHS FROM THE COLORADO BASIN, ARGENTINA

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
. Based on palynological studies, paleoclimatic trends were inferred for the Paleocene-Miocene of the marginal part of the Colorado Basin, Argentina. The data show warm and humid conditions during the Late Danian (Paleocene), a decline of temperature and

Dual Impact of Long‐Lived Localized Carriers Induced by Restricted Hole Transfer in Organic Photovoltaics and Photocatalytic Hydrogen Evolution

open access: yesAdvanced Energy Materials, EarlyView.
This work clarifies why organic semiconductors perform differently in photovoltaic devices and photocatalytic nanoparticles. By examining D18:Y5 and PM6:Y6 systems, we show how aggregation, exciton lifetime, and interfacial charge transfer behavior govern energy‐conversion pathways.
