Synthesis, Vibrational Analysis, Optical, Ionic Conductivity and Conduction Mechanism of γ-NaCoPO4 Compound by Karoui K* in Crimson Publishers: Peer Reviewed Material Science Journals 

Sodium cobalt monophosphate (γ-NaCoPO4) compound was synthesized by a solid-state reaction. X-ray powder diffraction analysis indicated that this sample is well crystallized in the monoclinic system Zéolite ABW structure with P21/n space group. The vibrational study showed the appearance of the tetrahedral PO4 and its vibrations. The electrical measurements of this compound were analyzed by complex impedance in the frequency range (43Hz-102MHz) at several temperatures. Nyquist plot at several temperatures revealed a single semicircle associated to the grains. The temperature dependence of the conductivity for the grain obeys to the Arrhenius law. The AC conductivity is insured by a process defined as a hopping transport mechanism. The thermal behaviors of the exponent ‘S’ indicate that the Correlated Barrier Hopping model (CBH) is the most dominant mechanism. The analysis of the data unfolded that the optical gap energy is determinate using Kubelka-Munk function and the value of Urbach energy is equal to 0.395eV.

This research was aimed to investigate the modification of surface structure and crystallinity of water hyacinth after recombinant α-L-arabinofuranosidase treatment. The process of water hyacinth hydrolysis was optimized first, by determination of the most optimal intracellular enzyme (P) and extracellular enzyme (S) mixture ratio, and its incubation time. The optimum of water hyacinth hydrolysis process was achieved at ratio P:S = 1:2, after 8 h incubation. The surface structure of water hyacinth after recombinant α-L-arabinofuranosidase treatment was analyzed by scanning electron microscope (SEM) and X-ray diffraction (XRD), using untreated water hyacinth as control. This research showed that enzymatic hydrolysis damaged the surface structure of water hyacinth and changed its crystallinity. Similar result also indicated that, the α-L-arabinofuranosidase could also damaged the surface structure of rice straw at the optimum ratio of enzyme mixture was 1:1, also after 8 h incubation. The enzyme used in this research can be applied further for bio-bleaching of paper pulp and animal feed stock, while the sugar product can be applied for bioethanol production.
