Unlocking the Photoluminescence and Photostability of Au11 Clusters through Pt-Mediated Band-Gap Engineering.

Au nanoclusters often demonstrate useful optical properties such as visible/near-infrared photoluminescence in addition to remarkable thermodynamic stability owing to their superatomic behavior. The smallest of the 8e- superatomic Au nanoclusters, Au11, has limited applications due to its lack of luminescence and relatively low stability. In this work, we investigate the introduction of a single Pt dopant to the center of a halide- and triphenylphosphine-ligated Au11 nanocluster, obtaining a cluster with a proposed molecular formula PtAu10(PPh3)7Br3.

Nation-wide cross-sectional study of participation and predictors of enjoyment among Australian adult walking sport participants.

This study examined participation and predictors of walking sports enjoyment among Australian adult walking sport participants. An online cross-sectional survey assessed walking sport participation, enjoyment, and barriers and motives to participation. Physical activity behavior and motivations were also assessed.

Differentiating Separate Primary Lung Adenocarcinomas From Intrapulmonary Metastases With Emphasis on Pathological and Molecular Considerations: Recommendations From the International Association for the Study of Lung Cancer Pathology Committee.

Introduction: With the implementation of low-dose computed tomography screening, multiple pulmonary tumor nodules are diagnosed with increasing frequency and the selection of surgical treatments versus systemic therapies has become challenging on a daily basis in clinical practice. In the presence of multiple carcinomas, especially adenocarcinomas, pathologically determined to be of pulmonary origin, the distinction between separate primary lung carcinomas (SPLCs) and intrapulmonary metastases (IPMs) is important for staging, management, and prognostication.

Methods: We systemically reviewed various means that aid in the differentiation between SPLCs and IPMs explored by histopathologic evaluation and molecular profiling, the latter includes DNA microsatellite analysis, array comparative genomic hybridization, TP53 and oncogenic driver mutation testing and, more recently, with promising effectiveness, next-generation sequencing comprising small- or large-scale multi-gene panels.

Barriers and Facilitators to Physical Activity Among Older Adults in Residential Aged Care Facilities: A Mixed Methods Systematic Review Using the Social Ecological Model.

Objective: To ascertain the barriers and facilitators to physical activity (PA) for older adults in Residential Aged Care Facilities (RACFs), from the perspective of residents, staff, and family.

Methods: A mixed-methods systematic review, underpinned by the Social Ecological Model (SEM). Five databases were searched from inception to May 2024.
