Linear Viscoelastic Behavior of n‐Alkane Diluted Polyethylene Melts: Sorption, Desorption, and Oscillatory Rheometry

open access: yesJournal of Applied Polymer Science, EarlyView.
This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...

Long‐Time Thermal Aging of Perfluoroalkoxy Polymers for Electrical Insulation: Structural and Physical Properties Evolutions

open access: yesJournal of Applied Polymer Science, EarlyView.
This work focuses on the investigation of the influence of a long‐time exposition to accelerated thermal aging on the physicochemical structure and properties of PFA. Results show a decrease in the melting temperature and crystal ratio due to chemical aging.

Valorization of Post‐Consumer Waste From Metallized Flexible Packaging and Industrial EPM Waste: Development of Sustainable Composites

open access: yesJournal of Applied Polymer Science, EarlyView.
Post‐consumer metallized flexible packaging waste and industrial EPM waste are transformed into sustainable composites through mechanical recycling. The incorporation of 30 wt% EPM provides the most favorable balance between stiffness, ductility, and impact resistance, achieving 53.36 kJ/m2.

Fibrillisation and Mechanical Properties of Plasma‐Treated Modification LDPE/PA6 Microfibrillar Composites

open access: yesJournal of Applied Polymer Science, EarlyView.
Plasma treatment enhances interfacial adhesion between LDPE/PA6 via carbonyl group formation. PA6 droplet size heterogeneity reduced to ~850 nm after plasma treatment. Drawing at 160°C produces highly oriented microfibrils with faster throughput. Plasma‐treated MFCs show up to 500% tensile strength increase and 18% higher stiffness.

Fasting and Refeeding Mediated Phospholipid Remodeling Plays an Important Role in Improving Meat Quality of Aged Laying Hens

open access: yesAnimal Research and One Health, EarlyView.
ABSTRACT This study explored fasting‐induced physiological remodeling effects on meat quality in aged laying hens. Fasting for 15 days (F15) significantly reduced abdominal fat, intermuscular fat width, subcutaneous fat thickness, and liver index versus pre‐fasting (F0) (p < 0.05), which recovered post‐refeeding.

Thermal-Hydraulic Analysis of a Pneumatic Resonating Device

open access: yes, 2012
Resonator AS is developing a hammer drilling system suitable for oil and geothermal drilling. The nature of the device involves high speed linear motion at high frequencies. As a result of this, the gas springs used in their device are subject to high pressures and temperatures. To prevent pressure leakage from the device, seals are installed.The seals

Thermophilic anaerobic treatment and biogas generation from wastewater produced in an advanced biorefinery process

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Anaerobic digestion can be an alternative method for treating wastewater from second‐generation biorefineries while simultaneously producing biogas. However, the feasibility of the process and key operational parameters by which wastewater produced in lignocellulosic biorefineries affects reactor performance remain poorly understood.

Spatio‐Temporal Assessment of Fish Biodiversity in High‐Density Cascade Dam Rivers Using Environmental DNA Metabarcoding

open access: yesBiological Diversity, EarlyView.
This study employed eDNA technology for biodiversity surveys and conducted high‐density spatiotemporal eDNA sampling to evaluate ecosystem‐scale patterns across temporal, spatial, and habitat dimensions. We identified 97 fish species from 12 orders, 29 families, and 71 genera using eDNA technology. Spatially, fish diversity indices were correlated with

Circular Economy in the Management of Wastewater Treatment Plant: A Business Model Approach

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The water and wastewater management sector faces many challenges related to the implementation of a circular economy (CE). To date, sectoral CE solutions have focused mainly on technological innovations, with limited attention paid to social and economic aspects.
