Citric‐Acid Polyester‐Modified Melamine–Formaldehyde Resins: Mechanistic Insights and Implications for Greener Decorative Laminates

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
Driven by the need for more sustainable materials in the laminate industry, poly(glycerol citrate) was introduced as a bio‐based modifier that significantly altered the cure kinetics and structural evolution of melamine–formaldehyde resins. Correlated FTIR, DSC, TGA, and rheological analyses revealed accelerated network formation, enabling lower ...

Material Characterization of Lignin‐Filled Polypropylene Composites

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
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

Effects of Biotin on a Fluorescein‐Based Photosensitizer Revealed by Multiscale Computational Modeling

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Biotinylation of a fluorescein‐based photosensitizer enhances its performance in PDT through a synergistic dual action. In addition to Type II singlet oxygen generation common to both dyes, the biotinylated system induces stronger membrane perturbation and higher local accumulation in lipid membranes, associated with increased water permeability and ...

ANALYSIS OF THE STIFFENED PLATE CONTAINING WEB FRAMES

open access: yesANALYSIS OF THE STIFFENED PLATE CONTAINING WEB FRAMES
An analysis by the matrix method is given to a plate, stiffened in one direction, provided with web frames or girders and ordinary frames and subjected to lateral load. The basic equation for the stiffened plate is introduced by combining the plane stress theory and the bending theory of plate.
