Improving Oxygen Barrier Performance of Polylactide Film by Using Bleached and Unbleached Nanocellulose From Grape Pomace

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 14, April 10, 2026.
Bleached and unbleached nanocelluloses were produced from the exhausted grape pomace and applied as coatings on PLA substrates for sustainable food packaging. Unbleached nanocelluloses were more hydrophobic and amorphous than bleached ones. The resulting bio‐based bleached nanocellulose‐coated PLA films showed a 68% reduction in O2 permeability ...

Sustainable Hybrid Films Based on Ecovio, Sodium Nitrite, and Babassu Mesocarp Starch for Potential Packaging Applications

open access: yesPolymers for Advanced Technologies, Volume 37, Issue 3, March 2026.
ABSTRACT Replacing conventional plastics in packaging requires biodegradable formulations that balance mechanical performance, thermal stability, and scalable melt processing. Despite growing interest in PBAT/PLA systems, few studies have concurrently incorporated an inorganic additive and a regionally sourced biomass derivative into an Ecovio matrix ...

LDL Cholesterol Modulates Astrocyte Metabolism, Lipid Handling, and Morphology: Evidence From In Vitro and In Vivo Models

open access: yesJournal of Neurochemistry, Volume 170, Issue 3, March 2026.
In vitro, low‐density lipoprotein cholesterol (LDL cholesterol) promotes the accumulation of lipid derivatives in astrocytes. Additionally, LDL cholesterol exposure causes a decrease in the expression of low‐density lipoprotein receptor (LDLr), 3‐hydroxy‐3‐methylglutaryl‐CoA reductase (HMGCR), and sterol regulatory element‐binding transcription factor ...

Tidal versus fluvial point bars: Key features from the integration of outcrop, core and wireline log information of Triassic examples

open access: yesThe Depositional Record, Volume 10, Issue 5, Page 793-820, November 2024.
Abstract The Triassic red beds of the Tabular Cover of the Iberian Meseta are an excellent reservoir outcrop analogue, a direct consequence of high‐quality exposures, which offer exceptional three‐dimensional outcrops, as well as a wide variability of depositional environments.

EFFECTS OF SPATIAL RESOLUTION ON ARRHYTHMIA DRIVERS’ DETECTION AND LOCALIZATION: INTER-ELECTRODE RECOMMENDATIONS FOR CARDIAC ELECTROPHYSIOLOGICAL MAPPING DEVICES [PDF]

open access: yes, 2022
Arrhythmia is a cardiac rhythm disorder that can be fatal. Its treatment includes ablation of the cardiac tissue and/or defibrillation. Advances are being made for both treatment options to localize the culprit region and apply therapy directly where ...

TRAM: A new non‐hydrostatic fully compressible numerical model suited for all kinds of regional atmospheric predictions

open access: yesQuarterly Journal of the Royal Meteorological Society, Volume 150, Issue 759, Page 1124-1156, January 2024 Part B.
A new limited‐area numerical model (TRAM, for Triangle‐based Regional Atmospheric Model) is presented and validated through numerous two‐dimensional and three‐dimensional tests. It performs as well as state‐of‐the‐art models and is suitable to simulate circulations ranging from small‐scale thermal bubbles to synoptic‐scale baroclinic cyclones ...
