Material Characterization of Lignin‐Filled Polypropylene Composites

open access: yesJournal of Applied Polymer Science, EarlyView.
Ground and spray‐dried lignin powders are compared as fillers for polypropylene composites. Differences in powder preparation methods are associated with differences in powder characteristics and composite behavior after melt compounding. Spray‐dried lignin produces smaller particles and fewer large agglomerates, while a 5 wt% lignin loading provides a

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.

“Dead Lithium” Formation and Mitigation Strategies in Anode‐Free Li‐Metal Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Anode‐free lithium metal batteries, though promising due to their high energy density, face challenges from dead lithium formation. “Dead lithium”, disconnected from the anode, causes capacity loss, increased resistance, and safety risks. This review explores the origins of dead lithium, its impact on battery performance, and potential strategies for ...
