Applied Sciences grants Noor Malik Saadoun PH.D. for her thesis entitled“Using LIBS for different metal detection”
Noor Malik Saadoun, a graduate student, optained her Ph.D. from the Department of Applied Sciences at University of Technology for her thesis entitled "Using LIBS for different metal detection " at the hall of the deceased Prof. Dr. Abdul Muttalib Ibrahim Al-Sheikh in the department.
The discussion committee, consisted of Prof. Dr. Mohamed Rady Mohamed as apresdent ,. Prof. Dr. Evan Tariq Salem., Dr. Kadhim Abdul Wahid Aadm,M.D. Raad Azawi Khamis. Dr. Qusay Adnan Abbas as members and Dr. Sabah Habib Sbeih supervisor and Dr. Naseer Mahdi Hadi co-supervisor.
The studying included, metallic nanoparticle was fabricated by an efficient and size – controlled. Many parameters have been studied and structural properties were investigated and analyzed. Structure and surface morphology of Nanoparticles were characterized by X-ray diffraction. Atomic Force Microscope and Scanning and Electron Microscopy measurements.
Annealing was in air at a specifics temperature of (400) ̊ C and at a constant time of (75 min); the XRD for cu - NPs technique that showed these films is monoclinic structure with a preferred orientation. Lattice parameters are a = 4.84 Å, b = 3.47 Å and C = 5.33 Å. Corresponding to plane (002) and (111) , (222) ,(113) the XRD profile of Al-NPs was shown with diffraction peaks of (111, 200, 220 , 311), where the peaks at 111 and 200 were the most intense. The estimated average size corresponding to the most intense crystallographic plane (111) was determined to be 40 nm. The AFM Analysis suggested the size of Al-NPs as 45 nm . Four sharp peaks appeared at 2θ = 38.5°, 44.7°, 64.7°, and 77.6°, which can be assigned to the (111), (200), (220), and (311) planes of the face centered cubic (FCC) structure of metallic silver.
In the second part for diagnosis the metal sample for (Al, Ag Cu ) emission spectroscopy with different laser energy of ( 81.5,134.5,221 , 240 and 319) mj with a specific distance between the fiber optic and the target with 5mm , where the experiment was in air. Identification for emission spectrum line was analyzed based on the NIST data base.
It is noticed that the intensity of spectrum lines, which is in (a.u) , increases with laser energy increase; in addition, the plasma parameter for electron temperature and electron density number also increase that for bulk material .
For the enhancement of the LIBS technique we diagnosis the nanoparticles emission spectroscopy and calculated the plasma parameters. it was found the intensity increases in different values higher than for bulk material with the same position for peaks , plasma parameter also increases for electron temperature also reached to saturation value but the values electron density number decrease for NE-LIBS.
It is mentioned that the scientific expert of the thesis, is Prof. Dr. Alya Mohsen and the linguistic expert is Prof. Dr. Omar Farouk Lutfi.

Applied Sciences grants Farah Hamed Rashid PhD for her thesis entitled " Preparation and characterization of polymer composite for biofilteration application "
The graduate student Farah Hamed Rashid optained her Ph.D. from the Department of Applied Sciences at the University of Technology for her thesis entitled " Preparation and characterization of polymer composite for biofilteration application " in the field of materials technologies, which was held in the hall of the deceased Dr. Abdul Muttalib Ibrahim Al-Sheikh.
The discussion committee consisted of professors Balqees Mohammed Ziauddin as a president and Prof. Dr. Salma Mohamed Hassan, Prof. Dr. Enas Mohy Hady, Prof. Abdel Hamid Rahim El Sarraf, Prof. Amal Ali Hussein as members, Prof. Nahida Gomaa Hamid Supervisor, Prof. Ali Abd El Rahman Taha Co-supervisor.
The studying included In the present study,preparation andcharacterizationof polymer system tobe usedas biofilterhave been investigated.
Chitosan / root or shoot powders and ash ofwater hyacinth (Eichhorniacrassipes) alone and in composite forms at differentratios (2.9 - 30.3%) were prepared ,separately.Two type of waste water were used in the present study.The first one was collected and prepared at different concentrations (250-1000 ppm) as a standard.Higher removal ratio was observed when pb(ll) , Cu(ll) and Cd (ll) were treated with plant shoot or root powders .On the other hand, SEM images displayed a regular shape and high porosity of prepared samples, while FTIR spectra of composite materials showed the characteristic of raw materials bands, which give strong evidence of composite formation . Moreover, the heavy metal removal increased whenever plant root or shoot ratio increased, while the removal by root powder of plant was more than the shoot. On the other hand , the results proved that the highest heavy metal removal, by chitosan beads , were12 , 15 and 18 % forCd , Cu and Pb, respectively.Furthermore, the resultsdisplayed that the compositeof chitosan and plant parts exhibited excellent ability to remove heavy metals. Lower amount of plant root with 30 mg chitosan appeared 100% removal of Cu(ll) , 86% of Pb and 60% of Cd(ll) , while the plant shoot ash hyacinth plant with chitosan composite removed 98.2% of Pb , 98% of Cu and 60% of Cd , when 250 ppm of metals was used.
The effect of pHand temperatureon free and immobilized laccaseto decolorize phenol red dyewere studied .The optimum pH and temperature of immobilized laccase was 4.6 and30◦C , respectively .Synthetic and natural mediators , HBT and Vanillin , were used to enhance phenol red decolorization and in LMS . The decolorization percentage of phenol red by chitosan composite with plant root was 100% within 210 minutes in the presence HBT mediator. On the other hand , higher conversion of anthracene was observed by chitosan/ plant parts powder in the presences of HBT at 30 ºC within 24 hrs.
The ability of composite recycling , as a sorbent material , wasinvolved.It was seenthat the removal efficiency ofheavy metals was decreased within 6cycles and the adsorption ability reduced to 20% , while the activity reaches to 60% after 9 cycleswhen immobilized laccase in chitosan beads was used.
In conclusion ,the composite acts asabiofliter through removal heavy metals as adsorbent ;decolorization of phenol red dye and conversation ofanthracene in waste water treatment.The recycle studied indicated that the composite could be discount the cost of adsorbent material for the removal of heavy metals from aqueous solutions by reusing it many times.
