Abstract:
Nanoscale zero-valent iron (NZVI) particles and iron cross-linked alginate (FCA) beads were successfully used for the first time for phosphate removal and recovery. NZVI was successfully used for phosphate removal and recovery. Batch studies indicated a removal of ~96 to 100% phosphate in 30 min (1, 5, and 10 mg PO43--P/L with 400 mg NZVI/L). Phosphate removal efficiency by NZVI was 13.9 times higher compared to Microscale ZVI (MZVI) particles. The successful rapid removal of phosphate by NZVI from aqueous solution is expected to have great ramification for cleaning up nutrient rich waters. Th

Abstract:
<p>Further increase of erbium concentrations in Er-doped amplifiers and lasers is needed for the design of efficient, reliable, compact and cost-effective components for telecommunications and other photonic applications. However, this is hindered by Er concentration dependent loss mechanism known as upconversion. The upconversion arises due to non-radiative energy transfer (ET) interactions (migration and energy-transfer upconversion) among the Er ions exited to the metastable level that is used for amplification. The upconversion deteriorates the conversion efficiency of Er doped gain medium

>Magister Scientiae - MSc<br>During the course of this study iron oxide nanoparticles, which have been researched for drug-targeted delivery, were synthesised via the co-precipitation method and characterised using various methods. This study focused on the role of relevant capping agents for the inhibition of agglomeration of the particles; chitosan, polyvinyl alcohol (PVA) and poly lactic glycolic acid (PLGA) were the capping agents of interest. The study is an assessment of the effects brought about the different capping agents used for this work. The prepared particles were then capped wit

Abstract:
Current methods of cancer therapy and detection still warrant high demand and great developments. Utilising the fundamental magnetism of iron oxide nanoparticles, it is possible to harness that magnetic power for the development of new, influential therapeutic and imaging modalities. In this thesis, a detailed look into the use of iron oxide nanoparticles as a material for magnetic thermotherapy and bio-imaging will be undertaken. Iron oxide nanoparticles are synthesised using a common co-precipitation synthesis. Stabilisation was achieved with citrate molecules followed by advanced functional

New surface ligand coatings were designed and synthesized, and the resulting hydrophilic SPIONs in biological buffers were found to be compact, stable, highly magnetic, and biocompatible. Furthermore, the hydrophilic SPIONs were stable in vitro in serums and cells as well as in vivo in

Abstract:
Au-coated magnetic Fe nanoparticles have been successfully synthesized by partial replacement reaction in a polar aprotic solvent with about 11 nm core of Fe and about 2.5 nm shell of Au. In this work, a combination of TEM (transmission electron microscopy), XRD (X-ray Powder Diffractometry), EDS (Energy disperse X-ray spectroscopy), SQUID (Superconducting Quantum Interference Device), TGA (Thermograviometric analysis), UV-visible absorption spectroscopy and Faraday rotation were employed to characterize the morphology, structure, composition and magnetic properties of the products.

Doutoramento em Física<br>Este trabalho aborda algumas propriedades magnéticas e estruturais de nanopartículas de óxidos e óxidos-hidróxidos de ferro crescidos em matrizes híbridas orgânicas-inorgânicas. As matrizes híbridas, denominadas di-ureasils e obtidas pelo processo sol-gel, são compostas por uma rede siliciosa ligada covalentemente por pontes ureia a cadeias orgânicas de diferente peso molecular. A estrutura local dos di-ureasils não dopados está modelada como grupos de domínios siliciosos com dimensões nanométricas, estruturalmente correlacionados no seio de uma matriz rica em
