A master's thesis entitled The Photoelectrochemical Activity of Surface-Modified SnO₂ Nanoscale Thin Films was discussed in the Physics Department of the Faculty of Science at the University of Basra by graduate student Sahar Khudair Tawfiq.

The thesis aimed to improve the performance of tin oxide nanomembranes in the fields of biosensing and energy applications by studying their structural, optical, and photoelectrochemical properties, thereby contributing to the development of the efficiency of these materials in advanced technological applications.

The study involved the preparation of nanomembranes using SILAR technology, as well as conducting a series of tests and analyses using advanced equipment to evaluate their efficiency and potential in biomedical applications.
