Semiautomated classification of units in volcanic terrain based on three morphometric attributes derived from a digital elevation model (DEM)

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
The proposed method better responds to the needs of detailed cartography improving the working scale (local and regional) representation; also roughness attributes facilitate the identification of geomorphological units, and the DEM generation method enhances terrain representation.

Curcumin Nanoformulations for Dermatological Applications: From Nutraceuticals to Nanocarriers

open access: yesFood Frontiers, Volume 7, Issue 3, May 2026.
Nanotechnology‐based delivery platforms enhance the cutaneous administration of curcumin. Loading free curcumin into polymeric micelles, metal‐based nanoparticles, nanogels/hydrogels, liposomes, polymeric nanoparticles, or nanoemulsions/nanocrystals helps address its low solubility, poor stability and limited skin permeation. As a result, these systems

Practices, barriers, and opportunities for dietitians‐nutrionists in critical care in Latin America: A cross‐sectional study

open access: yesJournal of Parenteral and Enteral Nutrition, Volume 50, Issue 4, Page 582-592, May 2026.
Abstract Background Dietitians–nutritionists (DNs) play a key role in intensive care units (ICUs), yet their scope of practice varies across settings. This study aimed to describe the professional practices of DNs working in ICUs in Latin America and to identify factors associated with their level of professional activity.

Exploring the Role of Activating Agents on the Electrocatalytic Activity of Grape Pomace‐Derived Catalysts for the Oxygen Reduction Reaction

open access: yesSmall Science, Volume 6, Issue 5, May 2026.
This work explores the influence of KOH (alkaline agent) and ZnCl2 (pore‐generating agent) on the one‐step chemical activation of wine grape pomace to produce Fe‐N‐C catalysts for the oxygen reduction reaction (ORR). The analyses reveal that KOH activation generates a highly porous structure with Fe‐Nx sites, leading to a larger electrochemically ...

Spatial and Temporal Variability of Eastern Pacific Radiocarbon and Carbon Chemistry From the Ice Age to Today

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Proxy records of seawater radiocarbon (14C/C) provide strong constraints on how changes in ocean ventilation contributed to the increase in atmospheric CO2 during the termination of the last ice age (≈18,000‐to‐12,000 years ago). One outstanding problem, however, is the existence of anomalously low deglacial benthic foraminiferal 14C/C in the ...
