An automated daily QA strategy for dosimetry and imaging guidance check of a novel PET/CT ring gantry linac. [PDF]

J Appl Clin Med Phys
Abstract Background The RefleXion X1 is a novel PET/CT‐guided ring gantry linac that introduces unique geometry and workflow compared to conventional systems. Existing QA guidelines (AAPM TG‐142, 148, 306) cover standard linacs and tomotherapy but do not address this platform's needs.

Supramolecular 3D Polymers Created via Chalcogen Bonding Using Benzotellurazoles as Planar Recognition Units. [PDF]

Chemistry
Starting with small planar benzotellurazoles, it is possible to create 3D supramolecular architectures. These exhibit a high degree of cross‐linking, which is caused by various chalcogen bonding (ChB) motifs. Introducing electron‐withdrawing substituents onto the benzotellurazole makes the ChB motifs more apparent and results in more complex ...
