Biodegradation of PBAT‐Silane Functionalized Nanocellulose Composite Films Under Industrial Composting Condition

open access: yesPolymer Engineering &Science, Volume 65, Issue 11, Page 5908-5919, November 2025.
This study evaluated the biodegradation behavior of PBAT and its nanocomposites, prepared by melt blending with either unmodified or phenyl silane‐modified cellulose nanocrystals, under simulated industrial composting conditions. Results showed that both composites degraded faster than neat PBAT, with PBAT‐CNC exhibiting the highest fragmentation and ...

Facile Decellularization of Stem Cell Spheroids by Integrating Bioactive Nanofibers for Enhanced Wound Healing

open access: yesSmall, Volume 21, Issue 44, November 6, 2025.
Decellularized stem cell spheroids are limited by inefficient detergent penetration and biomolecule loss. A strategy using polydopamine‐coated nanofibers within hADSC spheroids enables efficient DNA removal while preserving extracellular matrix proteins.

Exploration of Structure–Property Relationships by Altering Glycol Backbone Unsaturation (Double/Triple Bonds) in Furan‐Based Polyesters

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 40, October 29, 2025.
This study explores how adding unsaturated groups to bio‐based furanic polyesters can change their stiffness and heat resistance. While this offers new possibilities, it also needs careful control during production. It is shown that solution polycondensation works well for making these materials and offers a path toward more flexible, stable, and ...

Regiocontrolled Cleavage of Dialkyl Ethers Using Regenerative Borates as a Sustainable Alternative to Boron Trichloride

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 40, October 29, 2025.
The use of triaryl borates for highly selective ether cleavage is described. The borate is regenerable from the aqueous extract of a previous ether cleavage reaction without repurification, making use of low toxicity boron and phenolic waste. Such strategies for CO cleavage are expected to be broadly applicable to synthetic manipulations where ...

Advanced Biodegradable Materials: The Development of PBS Hybrid Composites Reinforced With Natural Fibers, Lignin, and Sepiolite for Sustainable Applications

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 40, October 20, 2025.
Development of hybrid biocomposites based on Bio‐PBS with canabrava, ESB, sepiolite, and lignin to reduce cost and improve properties for injection molding applications. The materials were processed via twin‐screw extrusion and characterized for mechanical, thermal, morphological, and rheological performance.

Time dependent fracture of polymers [PDF]

open access: yes, 1989
The fracture behavior of polymers is reviewed with emphasis on the time dependent aspects of the problem. Following a delineation of the history of crack propagation investigations in linearly viscoelastic materials, the effects of temperature and ...
