Stretching decelerates ring-opening metathesis at cis-olefins in stressed molecular bows [PDF]

open access: yesNature Communications
Ring-opening metathesis polymerization (ROMP) of strained cycloalkenes, driven by angle strain relief, has emerged as a powerful and versatile approach for synthesizing macromolecular materials. Nevertheless, the ROMP of C=C bonds upon stretching remains

Bidirectional Disulfide Metathesis Enables Recycling of High-Performance Thermoset Networks. [PDF]

open access: yesAdv Sci (Weinh)
A cyclic aromatic disulfide comonomer enables dual‐mode recyclable pDCPD thermosets through bidirectional disulfide metathesis. The resulting networks combine enhanced mechanical performance with thermal reprocessability and chemical depolymerization into reusable oligomeric fragments, allowing regeneration of high‐performance thermosets with minimal ...

Boron-Functionalised exo-Norbornene Monomers for ROMP: Toward Coordination-Active Poly(norbornene-B-arylene-dioxaborepine)s [PDF]

open access: yesMolecules
A series of boron-functionalised exo-norbornene monomers bearing boronic ester groups were synthesised via a condensation reaction and subsequently polymerised through ring-opening metathesis polymerisation (ROMP) to afford well-defined poly(norbornene-B-

Is self-perception related to speech perceptual analysis measures in early- and late-onset Parkinson’s disease? [PDF]

open access: yesDementia & Neuropsychologia
. Dysarthria is prevalent in Parkinson’s disease (PD) and has negative effects on communication and social interaction. A gap exists in understanding whether patient-reported outcome measures can effectively identify speech disorders prematurely ...

C6-ROMP Enabled by Structure-Guided Monomer Design for Chemically Recyclable Polymers [PDF]

open access: yesNature Communications
Cyclohexene, a minimally strained cyclic olefin, presents a long-standing challenge for ring-opening metathesis polymerization (ROMP) due to its inherently low ring strain energy.

Romp! [PDF]

open access: yes
Composed in 2020, this string quartet is fun and playful, for both the performers and audience to enjoy. Romp! is meant to get people's feet tapping and be a happy distraction. In rondo form, Romp! opens with a jaunty melody in the first violin.

Facial expression analysis to uncover the relationship between sialorrhea and hypomimia in Parkinson’s disease [PDF]

open access: yesFrontiers in Neurology
Sialorrhea, or excessive drooling, is a prevalent yet frequently under-recognized non-motor symptom of Parkinson’s disease (PD). Hypomimia, or reduced facial expressivity, constitutes another significant feature of PD.
