Light Spectrum of Compact Fluorescent Lamps in Iranian Market and Possibility of Hydroxyl Radical Production

Background and purpose: Despite growing use of energy-saving lamps or compact fluorescent lamps (CFLs), there are concerns about ultraviolet radiation in their output. In this study, the output of CFLs available in Iranian market in the range of infrared, visible, and ultraviolet were measured and the possibility of hydroxyl radical production by their radiation was evaluated. Materials and me...

Technological developments in lipidomics.

Lipid analysis is a well-established field of research that focuses on one lipid or a few lipids. The recent developments in mass spectrometry technologies have enabled more comprehensive studies to be performed on lipids present in a sample. The move towards extensive lipid research has led to the coining of the term lipidomics, which is defined as the ensemble of lipids present in a sample. I...

An Overview of Technological Developments in Medical Applications of X-Rays and Radioactivity

The years 1895 to 1898 were momentous for their impact on health and human well beings. First, Wilhelm Roentgen noted a glowing fluorescent screen, caused by invisible rays. This event subsequently led to the discovery of X-rays in 1895, and thus the birth of the “atomic age”. Next Becquerel’s investigations of these mysterious rays led to his experiments with uranium salt crystals. He th...
