Degradation pathways and chemical stability of regenerated cellulose fiber-reinforced bio-polyamide 5.10 composites under acidic and alkaline conditions

Scientific Reports
Bio-based polyamides (PA) represent an emerging class of engineering biopolymers that combine high performance with renewable origins. In particular, PA5.10, derived from renewable monomers, offers an attractive alternative to petroleum-based matrices in

Tuning Wetting Properties Through Surface Geometry in the Cassie–Baxter State

Biomimetics
Superhydrophobic coatings are beneficial for applications like self-cleaning, anti-corrosion, and drag reduction. In this study, we investigated the impact of surface geometry on the static, dynamic, and sliding contact angles in the Cassie–Baxter state.

Patient therapy outcome modeling in cancer organoids is improved by cancer‐associated fibroblasts and organoid assembly convolution

Molecular Oncology, EarlyView.
Patient‐derived organoids (PDOs) from pancreatic, colorectal, and gastric cancers were used to evaluate standard and experimental therapies. Incorporating cancer‐associated fibroblasts (CAFs) into organoid cultures improved patient therapy outcome prediction.

Investigation of the synergistic effects of UV radiation and elevated temperatures on regenerated cellulose fiber-reinforced bio-polyamide 5.10 composites

Scientific Reports
This study examines the thermo- and photo-oxidative degradation of bio-based polyamide 5.10, both neat and reinforced with 20 wt% regenerated cellulose fibers (RCF). The materials were additionally modified with two UV stabilizers: a hindered amine light

National Action Plans: Effectiveness and requirements for the Global Plastics Treaty

Cambridge Prisms: Plastics
National Action Plans (NAPs) are a possible implementation measure for the Global Plastics Treaty, through a NAP-based approach. Their effectiveness in other international agreements is contested, and their current format allows for weak, voluntary ...

A Nanocellulose Polypyrrole Composite Based on Tunicate Cellulose

International Journal of Polymer Science, 2013
The water-dispersed conductive polypyrrole (PPy) was prepared via the in situ oxidative chemical polymerization by using ammonium persulfate (APS) as oxidant and tunicate cellulose nanocrystals (T-CNs) as a dopant and template for tuning the morphologies

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Welding of Plastics (II)

Journal of the Japan Welding Society, 1959
Experimental studies were made concerning to the annealing and corrosion of the welded P.V.C. plate of 2 nun in thickness. Effects of radiation to the mechanical properties of these materials were also performd.Tensile strength of welded P.V.C. is decreased by the corrosion of H2SO4 HCl and HNO3, and is increased gradually with annealing time.Although ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
