Self‐Immolative Gels: Programmable Degradation Using Self‐Immolative Linkers and Polymers

Chemistry – A European Journal, EarlyView.
Self‐immolative linkers and polymers undergo bond‐cleaving reaction cascades in response to specific stimuli. Their incorporation into gels can be harnessed to release cargo, induce property changes, or trigger degradation in a highly controlled manner. These functions can be employed in applications such as sensing and drug delivery.

Time-dependent microbiome dynamics in orthodontic thermoplastic materials: comparing PETG and TPU

Clinical Oral Investigations
This study compares the effects of thermoplastic polyurethane (TPU) and polyethylene terephthalate glycol (PETG) aligners on the oral microbiome and salivary pH during orthodontic treatment.Ten participants wore TPU and PETG aligners for 24 h. At five time points (1 min, 4, 8, 12, and 24 h), saliva was collected for pH analysis, and microbial samples ...

Investigation of the Critical Overhang Angle in Fused Filament Fabrication Technology

Macromolecular Symposia, EarlyView.
ABSTRACT In fused filament fabrication, overhangs are challenging because each deposited layer requires partial support from the previous layer. The frequently cited 45° guideline for unsupported printing originates from empirical practice and does not consistently represent process‐specific behavior.
