Multimaterial 3D Printing in Activating Bath Enables In Situ Polymerization of Thermosets with Intricate Geometries and Diverse Elastic Behaviors

Advanced Materials, Volume 37, Issue 43, October 29, 2025.
A new embedded 3D printing (EMB3D) strategy enables in situ polymerization of DCPD/COD‐based inks within a fugitive reactive matrix where the activator in the matrix cures the printed filament. Cured ink properties are tunable through DCPD‐COD comonomer ratios, yielding materials from stiff thermosets to soft elastomers.

Initiator‐Driven Tailoring of Reactivity and Inhibition in Frontally Polymerized Dicyclopentadiene‐Co‐Dihydrofuran Thermosets

Journal of Polymer Science, Volume 63, Issue 19, Page 4061-4074, 1 October 2025.
Initiator concentration increases front velocity, cure kinetics, and Tg in DCPD‐co‐DHF, while increased DHF inhibits the reaction and impacts thermoset deconstructibility.This effort develops an empirical kinetic model for front speed, expands the viable compositional space for regenerative thermoset manufacturing, and correlates DSC thermograms with ...

Morphogenic Growth 3D Printing

Advanced Materials, Volume 37, Issue 20, May 19, 2025.
I additive manufacturing process exploits the spatial propagation of a polymerization reaction front to produce 3D polymer parts 10× faster and 1000× more energy efficient than the fastest stereolithography. In contrast with existing 3D printing, this morphogenic process is inspired by biological “growth and form” due to the self‐directed propagation ...

Reactive Processing of Furan‐Based Monomers via Frontal Ring‐Opening Metathesis Polymerization for High Performance Materials

Advanced Materials, Volume 36, Issue 36, September 5, 2024.
New monomers capable of frontal ring‐opening metathesis polymerization are identified through computational screening of thermostability and ring‐opening metathesis polymerization exotherms. Subsequent experimental validation of physical properties of monomers, kinetics, and material properties reveal frontal ring‐opening metathesis polymerization ...

Ageing and the evolution of female resistance to remating in seed beetles [PDF]

Biology Letters, 2005
Abstract Female remating behaviour is a key mating system parameter that is predicted to evolve according to the net effect of remating on female fitness. In many taxa, females commonly resist male remating attempts because of the costs of mating. Here, we use replicated populations of the seed beetle Acanthoscelides obtectus selected

REMATING IN DROSOPHILA MELANOGASTER: ARE INDIRECT BENEFITS CONDITION DEPENDENT? [PDF]

Evolution, 2010
By measuring the direct and indirect fitness costs and benefits of sexual interactions, the feasibility of alternate explanations for polyandry can be experimentally assessed. This approach becomes more complicated when the relative magnitude of the costs and/or benefits associated with multiple mating (i.e., remating with different males) vary with ...

Non-fertile sperm delay female remating [PDF]

Nature, 1999
Sperm competition is thought to be responsible for the tremendous inter- and intraspecific variation in sperm number1 and size2. But why several animals produce a range of sperm types3,4, some of which are incapable of fertilizing the female's eggs4, has remained unexplained for nearly 100 years5.

Counter‐perfume: using pheromones to prevent female remating [PDF]

Biological Reviews, 2016
ABSTRACTStrong selection to secure paternity in polyandrous species leads to the evolution of numerous chemicals in the male's seminal content. These include antiaphrodisiac pheromones, which are transmitted from the male to the female during mating to render her unattractive to subsequent males.
