Exploring the Ring–Ring Expansion and Pyrazole Substitution of Chlorophosphazenes [PCl2N]3,4 Through Mechanochemical Ball‐Milling and Quantum Mechanical Computation

open access: yesJournal of Heterocyclic Chemistry, EarlyView.
Mechanochemical ball‐milling of cyclic chlorophosphazenes at room temperature enables ring–ring expansion to larger cycles and pyrazole substitution, avoiding hazardous solvents and high temperatures. ABSTRACT In this study, we are using low‐energy mechanochemical ball‐milling with [PCl2N]3–4 at room temperature as an alternative to high‐temperature ...

When Does Top Management Team Diversity Matter in Large Organizations?

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT Top management teams (TMTs) drive strategic leadership, but there is little clarity on when the composition of these upper echelons most impacts organization performance. Drawing from the categorization‐elaboration model, we study an 18‐year sample of approximately 4500 organizations and over 32 000 executives and find a positive relationship ...

Strawberry Gingivitis and Septal Perforation as Onset Manifestations of Granulomatosis With Polyangiitis Triggered by COVID‐19

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Strawberry gingivitis is a rare but characteristic manifestation of granulomatosis with polyangiitis (GPA), characterized by red‐purple, swollen, granular gingiva. We report a 31‐year‐old woman who developed GPA following a mild COVID‐19 infection, presenting with fever, fatigue, facial pain, chronic sinusitis, epistaxis and strawberry ...

Sterile Nasal Septal Abscess in Ulcerative Colitis With Crypt Abscess‐Like Neutrophilic Infiltration

open access: yesThe Laryngoscope, EarlyView.
We report a rare case of sterile nasal septal abscess in a patient with ulcerative colitis. Histopathological analysis revealed crypt abscess‐like neutrophilic infiltration in the nasal mucosal glands, resembling a typical feature of ulcerative colitis.

Emerging patterns of CO2 : O2 dynamics in rivers and their link to ecosystem carbon processing

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Aquatic metabolism is reflected in the dynamics of dissolved oxygen (O2) and carbon dioxide (CO2) concentrations. Thus, paired measurements of CO2 and O2 concentrations can capture the metabolic characteristics of an ecosystem, with promising results in lakes.
