Polyethylene–Cellulose Composites From Cellulose Xanthate Solutions

open access: yesJournal of Applied Polymer Science, EarlyView.
An approach for fabricating cellulose/LDPE composites through cellulose dissolution, LDPE dispersion, and subsequent hot‐pressing. ABSTRACT This study reports a processing route for fabricating cellulose/LDPE composites involving the dispersion of polyethylene powder in a cellulose solution, followed by regeneration to form a continuous cellulose ...

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

open access: yesJournal of Applied Polymer Science, EarlyView.
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 ...

Tailored Dual Responsive Hybrid Gelatin Methacryloyl/Poly[2‐(Dimethylamino)Ethyl Methacrylate] Hydrogels for Efficient Ibuprofen Release in Topical Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
GelMA/DMAEMA hybrid hydrogels for release of ibuprofen. ABSTRACT In this study, biocompatible hydrogels intended for topical delivery of ibuprofen were synthesized from gelatin methacryloyl (GelMA) and 2‐(dimethylamino)ethyl methacrylate (DMAEMA) by varying their proportions. The impact of different GelMA and DMAEMA ratios was comprehensively evaluated

Digital Spatial Technologies to Compose the Map of the Southeast Iberia Megalithic Phenomenon. The Case Study of Fonelas (Granada, Spain)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Megalithic landscapes in Southeast Iberia remain unevenly and insufficiently documented, particularly in rugged areas where traditional survey methods are limited. This paper addresses this gap by applying a multiscalar approach to the megalithic necropolises of the Fardes River (Granada, Spain), with the objective of detecting, documenting ...

Integrated bioconversion of starchy and hemicellulosic fractions of macauba oil presscake into ethanol by nonconventional yeasts

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Co‐fermentation of hexoses and pentoses from plant biomass to ethanol is a strategy to increase ethanol production from lignocellulosic materials and add value to residues from agroindustrial chains. The macauba (Acrocomia aculeata) is an oleaginous palm‐tree species considered to contribute to development in some regions of Brazil.

Raw citrus by‐product valorization: unlocking the potential of biotransformation by Talaromyces amestolkiae to obtain cellulolytic enzymes and natural colorants

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Agro‐industrial by‐products can be used as valuable nutrient sources for the sustainable production of high‐value‐added compounds. The goal of this study was utilize raw citrus industrial by‐product (RCB) as a carbon source for the simultaneous production of red colorants and enzymes by the filamentous fungus Talaromyces amestolkiae under lab ...

The Role of European Union (EU) Metagovernance in Supporting the Voluntary and Community Sector in Northern Ireland

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT This article argues that European Union (EU) peacebuilding scholarship can benefit from organizational research on the socio‐spatial dynamics of policy implementation. It introduces a strategic‐relational heuristic to address two key gaps: the marginalization of grassroots agency in spatial analyses and the separation of strategy from ...
