New high-performance photocatalytic materials are required to effectively treat water pollution. The effect of annealing temperature on the photocatalytic activities of tin dioxide (SnO₂) nanoparticles is investigated in this work. SnO₂ nanoparticles are prepared via a hydrothermal method and annealing at various temperatures ranging from as-prepared to 900 °C. The size of SnO₂ nanoparticles increases from 4 nm to 10 nm with an increase in annealing temperature. The photocatalytic properties of these nanoparticles are evaluated through the photocata

The coronavirus disease 2019 (COVID-19), which is caused by a novel coronavirus (SARS-COV-2), has compromised health care systems and normal management of patients with cardiovascular diseases [1-3]. Patients with non-communicable diseases, including acute myocardial infarction (AMI) are vulnerable to this stress [4, 5]. Acute ST segment elevation myocardial infarction (STEMI), the most critical type of AMI, is associated with high mortality even with modern medicine [6-8]. Timely reperfusion therapy is critical for STEMI patients becau
