Experimental evidence that estimates of demographic parameters depend on initial population size

Oikos, EarlyView.
Classical population models assume that estimated parameters, such as intrinsic growth rate, depend on the species of interest and its environment, but not on the initial population size N(0). However, it has been theoretically proposed that this dependence is a mathematical consequence of reducing a two‐dimensional system (e.g.

Lichen‐Derived Mineral Residue as a Renewable Particulate Filler in Polylactic Acid Biocomposites: Structure, Melt Rheology, Viscoelastic, and Flexural Behavior

Polymer Composites, EarlyView.
Lichen residue, a renewable mineral‐organic material, was melt compounded with polylactic acid and triacetin in a twin‐screw extruder. ABSTRACT A lichen‐derived natural material, known as “höllük” in southeastern Turkey, is introduced as a renewable filler for polylactic acid (PLA).

A Simple Rheology‐Based Framework for Selecting Printing Parameters in Extrusion‐Based Hydrogel Additive Manufacturing

Polymer Engineering &Science, EarlyView.
An open analytical framework converts standard rheological measurements directly into the complete extrusion field and slicer‐ready printing parameters for Piston driven printers, enabling rapid operational window of printability in direct ink writing without CFD or machine learning. ABSTRACT Predicting whether a gel formulation will print successfully

Friction‐Corrected In‐Situ Viscosity Measurement in Material Extrusion: A Force‐Based Method Validated Against Capillary Rheometry Using Identical Nozzle Geometry

Polymer Engineering &Science, EarlyView.
In the filament force measurement (FFM), the friction of the solid filament, determined in an open‐bore reference, is subtracted from the measured extrusion force to obtain the capillary force. The resulting apparent viscosity is compared with high‐pressure capillary rheometry (HPCR) using the identical printer nozzle in both instruments.

Deformation, Creep, and Dynamics in Glassy Ionomers

Journal of Polymer Science, EarlyView.
Ionic architecture tunes the inelastic deformation of glassy ionomers. Simulations show that ionic associations leave the small‐strain elastic baseline nearly unchanged, but strongly reinforce yielding, strain hardening, and creep resistance. Polyampholyte architectures suppress nonaffine mobility and stress‐induced fluidization most effectively by ...
