Integrating vision, audition and olfaction traits: a roadmap for contrasting sensory ecologies of birds and rodents

Oikos, EarlyView.
Sensory ecology seeks to understand how organisms detect and use information from their environment, yet comparative analyses across multiple sensory modalities remain rare. Here, we present a roadmap for contrasting the sensory ecologies of birds and rodents using surrogate morphological and acoustic traits associated with vision, audition, and ...

Moisture Absorption in Highly Porous Closed‐Cell Polymeric Foams

Polymer Engineering &Science, EarlyView.
The conventional one‐dimensional hindered diffusion model has been extended into a new Void Filling Hindered Diffusion Model. By quantifying the moisture stored within closed‐cell pores, this model successfully captures the distinct absorption behaviors observed across varying foam thicknesses.

Leucaena Oil Functionalized With Osmium Tetroxide as a Precursor for Polyol‐Based Polyurethane

Journal of Polymer Science, EarlyView.
Leucaena leucocephala seed oil is converted into a hydroxyl‐functional biopolyol through OsO4‐mediated dihydroxylation. The resulting biopolyol shows a hydroxyl number of 160–175 mg KOH g−1 and is successfully used to produce flexible, open‐cell polyurethane foams, highlighting a renewable route for converting underutilized biomass into value‐added ...
