Photochromic carbazole photoinitiators for precision visible‐light photopolymerization

open access: yesPolymer International, EarlyView.
New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...

Sustainable treatment of banana leaves for phytosanitary applications: impact, spreading, and impregnation of mineral oil

open access: yesPest Management Science, EarlyView.
Mineral oil droplets spread anisotropically, penetrate banana leaf tissues, and diffuse into the palisade parenchyma, revealing a delayed, Fickian mechanism that supports improved phytosanitary spray strategies. Abstract BACKGROUND Efficient application of phytosanitary sprays is essential for sustainable control of foliar fungal diseases such as Black

Role of Hearing Loss Genes in the Sensory Epithelia Associated With Meniere Disease

open access: yesSensory Neuroscience, EarlyView.
ABSTRACT Meniere disease (MD) is an inner ear disorder characterized by episodic vertigo, tinnitus, fluctuating sensorineural hearing loss (SNHL), and aural fullness. Its hallmark pathological feature is endolymphatic hydrops. MD shows significant familial clustering in European and East Asian populations, supporting a strong genetic component in ...

Contrastive Self‐Categorization as a Resource for Defending Cultural Stereotypes

open access: yesSymbolic Interaction, EarlyView.
This study explores how speakers defend morally sanctionable cultural stereotypes from challenges in adult second language classrooms. Within the conversation analysis and membership categorization analysis frameworks, I examine two extended video‐recorded class discussions in which students maintain face‐threatening, stereotypical portrayals of ...
