Phosphorescence of Heavy, T‐Shaped Pnictogen Trisamides in Solution at Room Temperature in the Near‐Infrared II Region

open access: yesChemistry – A European Journal, EarlyView.
The unique photophysical properties of heavy T‐shaped Sb and Bi trisamides are reported. A ligand‐to‐pnictogen charge‐transfer excitation from a redox‐active NNN pincer to a vacant pnictogen p‐orbital populates a triplet state that emits in the highly desirable NIR‐II region, with lifetimes up to the µs range.

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Validation of the TruBlue Light Laser for Laryngeal Somatosensory and Perturbation Testing

open access: yesThe Laryngoscope, EarlyView.
This study validates a blue light laser method for assessing laryngeal somatosensory function by measuring perceptual thresholds, reflexive responses, discrimination acuity, and vocal perturbations in healthy adults. Results demonstrate that the method provides precise, reliable stimulation and yields quantifiable sensory and acoustic responses ...

Voice and Speech in Atypical Parkinsonian Disorders

open access: yesMovement Disorders Clinical Practice, EarlyView.
Background Motor speech disorders are early, common, and functionally limiting features of atypical parkinsonian disorders (APDs) such as progressive supranuclear palsy (PSP), corticobasal syndrome (CBS), and multiple system atrophy (MSA). These impairments are underrecognized and undertreated in neurology clinics.
