Principles of Extraction

Dr. Safa Majeed Hameed     This article focuses on three widely used techniques for extraction of semivolatile organics from liquids: liquid–liquid extraction (LLE), solid-phase extraction (SPE), and solid-phase microextraction (SPME). Other techniques may be useful in selected circumstances, but these three techniques have become the extraction methods of choice …

The Liquid Crystals in Medicine

Assist. Proff. Mithaq M. Mehdy Al-Sultani          Lyotropic liquid-crystalline phases are abundant in living systems, the study of which is referred to as lipid polymorphism. Accordingly, lyotropic liquid crystals attract particular attention in the field of biomimetic chemistry. In particular, biological membranes and cell membranes are a form of liquid crystal. Their constituent molecules (e.g. phospholipids) …

Which is the random laser?

Assist. Proff. Mithaq M. Mehdy Al-Sultani      A random laser is a laser that uses a highly disordered gain medium. A random laser uses no optical cavity, but the remaining principles of operation remain the same as for a conventional laser. Random laser action has been observed in many different media, including semiconductor powder, nanostructured and …
