Book Synopsis Synthesis of Rare-earth Containing Nanoparticles by : Paula S. Rahman
Download or read book Synthesis of Rare-earth Containing Nanoparticles written by Paula S. Rahman and published by . This book was released on 2010 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rare earth based nanoparticles have luminescent and paramagnetic properties which have potential use for applications in medical imaging, display technologies and lasers. Some Ln 3+ ions luminesce in the visible range, for example Eu3+ emits in the red and Tb3+ in the green. Ln3+ optical emission is very narrow and is not affected by the local environment. This property has found use in emissive displays. Most Ln3+ ions are paramagnetic, again a property which is expected to remain in most Ln3+-based compounds. Gd3+ in particular has found use as an MRI contrast agent as it has a high magnetic moment. -- In this work attempts were made to synthesise europium, terbium and dysprosium phosphide (REP) nanoparticles. An organometallic-based precursor route with coordinating solvents using tris(dimethylamino) phosphine as the phosphorous source was chosen as the synthetic route. Results indicated that the target nanoparticles were synthesised when using rare earth chloride as the metal precursors and TOPO as the coordinating ligand and solvent. The products from these reactions were most likely a mixture of products containing rare earth phosphide and phosphate nanoparticles and large particles and rare earth-TOPO complexes. The experiments reported for the phosphide syntheses are unique as there are no other reports of rare earth phosphide nanoparticles. TDMAP has also rarely been used as a phosphorous source for the synthesis of phosphide nanoparticles. -- Europium, terbium and gadolinium fluorides (REF3) were synthesised using several methods including routes using trifluoroacetate-based precursors. One finding was that the europium fluoride nanoparticles in particular displayed very long-range self-assembly. Europium-doped gadolinium fluoride nanoparticles were rendered water-soluble by PEGylation.

Book Synopsis Nanostructural Materials with Rare Earth Ions by : Rafal J Wiglusz
Download or read book Nanostructural Materials with Rare Earth Ions written by Rafal J Wiglusz and published by Mdpi AG. This book was released on 2022-03-29 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Issue of "Nanostructural Materials with Rare Earth Ions: Synthesis, Physicochemical Characterization, Modification and Applications" is related to studies of nanometer-sized materials doped and co-doped with rare earth ions and the creation of periodically ordered nanostructures based on single nanoparticles. A small particle size implies a high sensitivity and selectivity. These new effects and possibilities are mainly due to the quantum effects resulting from the increasing ratio of surface-to-volume atoms in low-dimensional systems. An important factor in this context is the design and fabrication of nanocomponents displaying new functionalities and characteristics for the improvement of existing materials, including photonic materials, conductive materials, polymers and biocomposites. With this concept in mind, the aim of the Special Issue is to publish research on innovative materials and their applications. Topics to be covered in this Special Issue include, but are not limited to, the following: - Technology and applications of nanomaterials with rare earth ions; - Advanced physicochemical properties, characterization and modification of nanomaterials with rare earth ions; - Novel active materials, especially organic and inorganic materials, nanocrystalline materials, nanoceramics doped and co-doped with rare-earth ions with bio-related and emerging applications; - Magnetic properties of nano-sized rare-earth compounds; - Applications of nano-sized rare-earth-doped and co-doped optical materials.

Book Synopsis Cerium Oxide Nanoparticles and Gadolinium Integration by : Peter Eriksson
Download or read book Cerium Oxide Nanoparticles and Gadolinium Integration written by Peter Eriksson and published by Linköping University Electronic Press. This book was released on 2019-08-29 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: A challenging task, in the area of magnetic resonance imaging is to develop contrast enhancers with built-in antioxidant properties. Oxidative stress is considered to be involved in the onset and progression of several serious conditions such as Alzheimer’s and Parkinson’s disease, and the possibility to use cerium-contained nanoparticles to modulate such inflammatory response has gained a lot of interest lately. The rare earth element gadolinium is, due to its seven unpaired f-electrons and high symmetry of the electronic state, a powerful element for contrast enhancement in magnetic resonance imaging. Chelates based on gadolinium are the most commonly used contrast agents worldwide. When introducing external contrast agents there is always a risk that it may trigger inflammatory responses, why there is an urgent need for new, tailor-made contrast agents. Small sized cerium oxide nanoparticles have electronic structures that allows coexistence of oxidation states 3+ and 4+ of cerium, which correlates to applicable redox reactions in biomedicine. Such cerium oxide nanoparticles have recently shown to exhibit antioxidant properties both in vitro and in vivo, via the mechanisms involving enzyme mimicking activity. This PhD project is a comprehensive investigation of cerium oxide nanoparticles as scaffold materials for gadolinium integration. Gadolinium is well adopted into the crystal structure of cerium oxide, enabling the combination of diagnostic and therapeutic properties into a single nanoparticle. The main focus of this thesis project is to design cerium oxide nanoparticles with gadolinium integration. A stepwise approach was employed as follows: 1) synthesis with controlled integration of gadolinium, 2) material characterization by means of composition crystal structure, size, and size distribution and 3) surface modification for stabilization. The obtained nanoparticles exhibit remarkable antioxidant capability in vitro and in vivo. They deliver strongly enhanced contrast per gadolinium in magnetic resonance imaging, compared to commercially available contrast agents. A soft shell of dextran is introduced to encapsulate the cerium oxide nanoparticles with integrated gadolinium, which protects and stabilizes the hard core and to increases their biocompatibility. The dextran-coating is clearly shown to reduce formation of a protein corona and it improves the dispersibility of the nanoparticles in cell media. Functionalization strategies are currently being studied to endow these nanoparticles with specific tags for targeting purposes. This will enable guidance of the nanoparticles to a specific tissue, for high local magnetic resonance contrast complemented with properties for on-site reduced inflammation. In conclusion, our cerium oxide nanoparticles with integrated gadolinium, exhibit combined therapeutic and diagnostic, i.e. theragnostic capabilities. This type of nanomaterial is highly promising for applications in the field of biomedical imaging.
Book Synopsis Fluorescent Nanodiamonds by : Huan-Cheng Chang
Download or read book Fluorescent Nanodiamonds written by Huan-Cheng Chang and published by John Wiley & Sons. This book was released on 2018-11-12 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive reference on fluorescent nanodiamond physical and chemical properties and contemporary applications Fluorescent nanodiamonds (FNDs) have drawn a great deal of attention over the past several years, and their applications and development potential are proving to be manifold and vast. The first and only book of its kind, Fluorescent Nanodiamonds is a comprehensive guide to the basic science and technical information needed to fully understand the fundamentals of FNDs and their potential applications across an array of domains. In demonstrating the importance of FNDs in biological applications, the authors bring together all relevant chemistry, physics, materials science and biology. Nanodiamonds are produced by powerful cataclysmic events such as explosions, volcanic eruptions and meteorite impacts. They also can be created in the lab by high-pressure high-temperature treatment of graphite or detonating an explosive in a reactor vessel. A single imperfection can give a nanodiamond a specific, isolated color center which allows it to function as a single, trapped atom. Much smaller than the thickness of a human hair, a nanodiamond can have a huge surface area that allows it to bond with a variety of other materials. Because of their non-toxicity, nanodiamonds may be useful in biomedical applications, such as drug delivery and gene therapy. The most comprehensive reference on a topic of rapidly increasing interest among academic and industrial researchers across an array of fields Includes numerous case studies and practical examples from many areas of research and industrial applications, as well as fascinating and instructive historical perspectives Each chapter addresses, in-depth, a single integral topic including the fundamental properties, synthesis, mechanisms and functionalisation of FNDs The first book published by the key patent holder with his research group in the field of FNDs Fluorescent Nanodiamonds is an important working resource for a broad range of scientists and engineers in industry and academia. It will also be a welcome reference for instructors in chemistry, physics, materials science, biology and related fields.

Download or read book Lanthanides/Actinides: Chemistry written by Karl A. Gschneidner and published by . This book was released on 1994 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the Handbook is the second of a three-volume set of reviews devoted to the interrelationships, similarities, differences, and contrasts of the lanthanide and actinide series of elements. In particular this book considers the comparisons of the chemistry of the lanthanide and actinide elements. The lanthanide and actinide elements present a multitude of challenging physical and chemical problems resulting from the involvement of open F-shell electronic configurations. This is made clear in the chapters composing these volumes which cover topics such as: the experimental and theoretical aspects of solution absorption and luminescence spectra to reveal similarities and differences in the two f-series; the methods and effectiveness of separation by solvent extraction, ion exchange and necessary accompanying reactions; the comparative thermochemical and oxidation-reduction properties of lanthanide and actinide materials; interrelationships and comparisons of the halides; an examination of the relative hydration and hydrolysis behaviors of the lanthanides and actinides.
