Repurposing Waste Sulfur for the Ionic Vulcanization of Nanocellulose Hydrogels

Small Methods, Volume 9, Issue 12, December 1, 2025.
Herein the ionic crosslinking of cellulose nanocrystals using sodium polysulfides is demonstrated. Chain entanglement, derived from O‐Ca‐S bridges within a hydrogel structure forms hydrophobic occlusions, leading to a significant increase in the material storage modulus and the swelling potential, thus translating to a potential application in ...

The Importance of Rubber Compounding Approach in Damage Evolution and Fatigue Performance of Carbon Nanotubes Doped Natural Rubber

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 11, Page 4828-4841, November 2025.
ABSTRACT This study was aimed to investigate the fatigue life of carbon nanotubes (CNTs) filled natural rubbers (NR) prepared by two different compounding techniques, including wet and dry methods. This was done to correlate the presence of defects to fatigue performance and to identify the optimum dispersion approach for CNTs/NR.

Exploring Effect of a Ternary Filler System on Low Hysteresis and Improved Wet Grip Properties of Sustainable and Fuel‐Efficient Tyre Tread Formulations

Macromolecular Materials and Engineering, Volume 310, Issue 10, October 2025.
This study investigates the mechanical, thermal, and dynamic mechanical properties of an eco‐friendly, green tyre tread compound, focusing on a ternary filler (CB, exfoliated graphite/modified silica) system. These findings establish modified silica as a key enabler in the development of next‐generation green tyres, offering a high‐performance ...

Occurrence and Fate of 6PPD-Quinone in Urban Receiving Waters

, 2022
In the U.S. Pacific Northwest, coho salmon, (Oncorhynchus kisutch), annually exhibit acute mortality upon stormwater exposure when adult salmon migrate to urban and near urban creeks to reproduce.

Bioactivity of the ubiquitous tire preservative 6PPD and degradant, 6PPD-quinone in fish- and mammalian-based assays

Toxicological Sciences
Abstract 6PPD-quinone (N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine quinone), a transformation product of the antiozonant 6PPD (N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine) is a likely causative agent of coho salmon (Oncorhynchus kisutch) pre-spawn mortality. Stormwater runoff transports 6PPD-quinone into freshwater streams,

Endothelial-to-mesenchymal transition derived fibronectin mediates pulmonary fibrosis in mice following chronic exposure to ozone-oxidized 6PPD

Ecotoxicology and Environmental Safety
The release of N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylene-diamine (6PPD) and its environmental transformation products poses a significant respiratory health risk. While 6PPD-quinone has been widely studied, the toxicological profiles of other oxidation

The joint effects of salt and 6PPD contamination on a freshwater herbivore

, 2022
Using sodium chloride (NaCl) for de-icing roads is known to have severe consequences on freshwater organisms when washed into water bodies. N-(1,3-dimethylbutyl)-N '-phenyl-p-phenylenediamine, also known as 6PPD, is an antiozonant mainly found in ...

Watershed analysis of urban stormwater contaminant 6PPD-Quinone hotspots and stream concentrations using a process-based ecohydrological model

Frontiers in Environmental Science
Coho salmon (Oncorhynchus kisutch) are highly sensitive to 6PPD-Quinone (6PPD-Q). Details of the hydrological and biogeochemical processes controlling spatial and temporal dynamics of 6PPD-Q fate and transport from points of deposition to receiving ...
