Article Synopsis
- The study highlights the discovery of singlet-triplet (ST) inversion in certain triangle-shaped boron carbon nitrides, challenging Hund's first rule caused by strong electron-electron interactions.
- This ST inversion has significant implications for improving triplet harvesting in organic LEDs, making it a noteworthy advancement in the field.
- The research utilizes the Pariser-Parr-Pople model combined with advanced calculations to show that the ST inversion is mainly influenced by the arrangement of electron-donor and electron-acceptor groups around the molecular edge, rather than the shape of the triangles themselves.
The inversion of the lowest singlet and triplet excited states, observed in several triangle-shaped organic molecules containing conjugated carbon and nitrogen atoms, is an astonishing result that implies the breakdown of Hund's rule. The phenomenon attracted interest for its potential toward triplet harvesting in organic LEDs. On a more fundamental vein, the singlet-triplet (ST) inversion sheds new light on the role of electron correlations in the excited-state landscape of π-conjugated molecules.

Objective: The aim of this retrospective study was to evaluate functional autonomy and mortality in a group of older adults with hip fractures managed in an orthogeriatric setting 12 months after discharge and to determine if gender affected outcome.
Methods: In all participants, we assessed clinical history, functional pre-fracture status using activities of daily living (ADL) and in-hospital details.

Article Synopsis
- One in six older patients admitted for a hip fracture suffers a second fracture, with a majority not receiving necessary antiresorptive therapies.
- At a 15-month follow-up, those with a second fracture showed significantly higher risks of low mobility, rehospitalization, and increased mortality compared to first fracture patients.
- These findings underscore the importance of preventive measures to reduce the risk of subsequent fractures in older adults.
