Abstract Background and objectives: Hemin is a porphyrin compound derived from hemoglobin, the precursor of other porphyrin hemoglobin derivatives and the raw material of Hematin. Since hemin is widely used in medicine, we decided primarily to synthesize this substance in Laboratory and to determine the best way of hemin extraction from untransfused and expired blood units. Materials and Method...
Synthesis of Zr-ZA catalyst used as for esterification reaction glycerol with acetic acid anhydrous has been done. Catalysts are characterized using an infrared spectrophotometer, X-ray diffraction, and measurement surface acidity, while products a gas chromatography-mass spectrometer. Effect time re-addition studied by conversion selectivity value triacetin were yielded. Infra-red spectrophoto...
A systematic study of the attenuation electromagnetic radiation in Nuclear Track Detectors (NTDs) is carried out. The gamma-ray, X-ray, UV, visible, and infrared NTDs are investigated using NaI(Tl) detector, Gas Electron Multiplier (GEM) UV-Vis spectrophotometer, FTIR spectrophotometer respectively. values some important parameters (e.g., optical depth, coefficient, etc.) three commercially ava...
Background: Collagen is a protein that constitutes a major component of connective tissue and has many applications in the medical and non-medical fields. The increase in the world population and the need for proteins have led to a special focus on seafood. Furthermore, jellyfish is a rich and renewable source of collagen. Therefore, many researchers have shown interest in collagen extraction f...
