Bird-building collisions have recently received increased conservation, research, and policy attention. However, efforts to reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites, with standardized methods, and with consideration of species- and life history-related variation and correlates of collisions. We addressed these research needs with a coordinated data collection effort at 40 sites across North America. We estimated collision vulnerability for 40 bird species by accounting for their North American population abundance, distribution overlap with study sites, and sampling effort. Of 10 species we identified as most vulnerable to collisions, some have been identified in past studies (e.g., Black-throated Blue Warbler [Setophaga caerulescens]) while others emerged for the first time (e.g., White-breasted Nuthatch [Sitta carolinensis]), possibly because we used a and risk correlates vary by species.

Herein, ultrasound is employed as a microscopic pressure resource to generate reactive oxygen species (ROS) for piezocatalytic tumor therapy under catalytic mediation by piezoelectric tetragonal BaTiO3 (T-BTO). Under the ultrasonic vibration, the electrons and holes are unpaired and they are separated by the piezoelectricity, resulting in the establishment of a strong built-in electric field, which subsequently catalyzes the generation of ROS such as toxic hydroxyl (• OH) and superoxide radicals (• O2 - ) in situ for tumor eradication. This modality shows intriguing advantages over typical sonoluminescence-activate
