Characterization and Antimicrobial Characteristics of Chitosan Modified Hibiscus Sabdariffal.Extract
Journal Title: JOURNAL OF ADVANCES IN PHYSICS - Year 0, Vol 14, Issue 3
Abstract
Samples of Chitosan (Cs) natural polymer containing successive amount of Hibiscus sabdariffaLextract were sucssesfuly synthesized using traditional simple casting route. Prepared thin films were characterized using fourier transform infrared (FTIR). FT-IR of synthesized thin films reveals maintenance of the characteristic bands of chitosan in addition to the appearance of two new sharp intense bands at 1782 and 954 cm-1 intensified with increasing plant extract content and assigned to the interaction between NH2 of polymer skeleton with falvanoids present in the extract. Obtained data poit out to a formation of homogenous composite structure. X-ray diffraction data (XRD) reval no prounounced band indicating the amorphous structure of synthesized final polymeric product. In vitro antimicrobial studies were performed using both gram negative and positive bacteria in addition to Fungul and Yeast activity using simple minimum inhibition zone (MIZ) standeredroutain.

TRANSFER OF ELECTRIC CHARGE THROUGH Al-Se95Te5<LSm>-Te STRUCTURE
It is established that current passing through Al-Se95Te5<Sm>-Te structures is carried out by monopolar injection mechanism at participation of traps for holes. It is shown that the doping by samarium strongly infl...
The Deformation Structure of the Nuclei 32S and 36Ar
We applied two different approaches to investigate the deformation structures of the two nuclei S32 and Ar36 . In the first approach, we considered these nuclei as being deformed and have axes of symmetry. Accordingly, w...
