Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization

open access: yesAdvanced Functional Materials, EarlyView.
Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

open access: yesAdvanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Thermal energy storage materials for suppressing thermal runaway propagation in lithium-ion batteries: a review [PDF]

open access: yesEES Batteries
Thermal runaway propagation in lithium-ion batteries is a major factor leading to fires and explosions in energy storage systems. Thermal energy storage materials, especially phase change materials and thermochemical storage materials, demonstrate ...

Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
OEG‐functionalized Y6‐derived acceptors induce thermally driven vertical phase separation, enabling pseudo‐planar heterojunction organic photodetectors. The resulting PM6:YTEG‐4F and PM6:YTEG‐4Cl organic photodetectors suppress dark current density by approximately 260‐fold and 210‐fold, respectively, while maintaining efficient photoresponse ...

Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride

open access: yesAdvanced Functional Materials, EarlyView.
This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

The effect of square corners on the ignition of solids [PDF]

open access: yes, 1993
the influence of square corners on the ignition of a solid exposed to a step in surface temperature is analyzed by means of large activation energy asymptotics. This study begins by considering the case of a semi-infinite square corner, applicable to the

Optical diagnostics of the venting spray and combustion behaviour during Li-ion battery thermal runaway induced by ramp heating

open access: yes, 2023
[EN] Lithium-ion cells are one of the solutions with the most significant potential for energy storage in future transportation. However, a controlled ambient temperature is crucial for its application due to thermal safety.

Polymer Side‐Chain Electronic Effects Regulating Solvation Sheath for Low‐Temperature and High‐Voltage Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work reveals the influence of polymer side‐chain electronic effects on the Li+ solvation sheath in gel polymer electrolytes. Electron‐donating side chains induce the strong Li+ coordination and FDMA‐dominated solvation, impeding Li+ desolvation, whereas electron‐withdrawing side chains weaken Li+ coordination, facilitating anion‐rich solvation and
