In this work, we studied the effect of varying the volume of mixed halide perovskites on the structural, morphological and optical properties of deposited thin films. A two-step process of spin coating and dipping technique was employed so as to enha

Aims: We have previously shown that mild hyperthermia (39-42°C) rapidly induces apoptosis in H-HeLa cells arrested in mitosis but not in interphase cells and not in mitotic-arrested cells of other HeLa strains such as HeLa S3. Our goal was to test t

We used a simple chemical synthesis route to deposit nanorod-like cobalt oxide thin films on different substrates such as stainless steel (ss), indium tin oxide (ITO), and microscopic glass slides. The morphology of the films show that the films were
