On-Surface Synthesis and Characterization of Pentadecacene and Its Gold Complexes.

Acenes are an important class of polycyclic aromatic hydrocarbons that have gained considerable attention from chemists, physicists, and material scientists, due to their exceptional potential for organic electronics. They serve as an ideal platform for studying the physical and chemical properties of sp carbon frameworks in the one-dimensional limit and also provide a fertile playground to explore magnetism in graphenic nanostructures due to their zigzag edge topology. While higher acenes up to tridecacene have been successfully generated by means of on-surface synthesis, it is imperative to extend their synthesis toward even longer homologues to comprehensively understand the evolution of their electronic ground state.

Enhancing Prehospital Care During the Conflict in Ukraine: NATO's Role in Global Health Engagement.

Introduction: The conflict in Ukraine, ongoing since 2014 and escalating with the Russian invasion in 2022, has unveiled profound challenges in prehospital care essential for the survival and recovery of warfighters and civilians alike, necessitating a detailed examination of the current medical response mechanisms and their effectiveness.

Materials And Methods: This study provides an overview of these challenges and examines how these critical vulnerabilities have impacted the delivery of medical care in war-torn regions. It also explores the role of NATO and its member states in addressing these challenges, focusing on the efforts to standardize prehospital care, enhance training, and foster interoperability among medical services.

Implementing a behavioral physical activity program in children and adolescent survivors of childhood cancer: a pilot randomized controlled trial.

Purpose We aimed to document the acceptability (enrollment rate) and feasibility (phone call delivery rate) of implementing a behavioral PA intervention over 12 weeks, in addition to documenting its effects on patient-reported outcomes and physical functioning. This study also describes the costs of carrying out a behavioral PA intervention. A total of 40 participants were randomized in a 1:1 ratio.
