Nature of Anti‐Dissipative High‐Energy Excited States in Quaterpyridine‐Bridged Ruthenium Complexes

open access: yesAngewandte Chemie, EarlyView.
Upon photoexcitation, meta‐connected quaterpyridine‐bridged Ru complexes undergo fast inter‐ligand electron transfer like typical chromophores, but unusually slow intra‐ligand electron transfer within bridge‐centered MLCT states. The energy saved was exploited for photoreductions and photooxidations with model electron donors and acceptors ...

Polymer‐Incorporated Mechanically Compliant Carbon Nanotube Microelectrode Arrays for Multichannel Neural Signal Recording

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a soft microelectrode array based on vertically aligned carbon nanotube (CNT) forests, combining high conductivity with mechanical softness. A densification process and air‐pressure‐assisted flexibilization improve structural integrity, ensuring stable insertion and reduced inflammation.

Mesenchymal Stromal Cell Secretome and Its Key Bioactive Metabolites Induce Long‐Term Neuroprotection After Traumatic Brain Injury in Mice

open access: yesAdvanced Science, EarlyView.
Pischiutta F and coworkers identify prostaglandins and kynurenine as key mediators of the mesenchymal stromal cells‐derived secretome's neuroprotective effects. A synthetic cocktail composed of these factors promotes long‐term functional recovery, reduces brain structural damage, and modulates neuroinflammation after traumatic brain injury, supporting ...

Disparity of turbinal bones in placental mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Nuclear parcellation of pontine catecholaminergic and cholinergic neurons in gray parrots and pied crow brains

open access: yesThe Anatomical Record, EarlyView.
Immunohistochemical staining for tyrosine hydroxylase reveals the neurons forming the locus coeruleus complex in the pontine region of the brain of the Congo gray parrot. The appearance and parcellation of the locus coeruleus complex in birds shows many similarities, but also differences to that observed in mammals.
