Download or read book Cerium written by Nader Shehata and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cerium is one of the most important lanthanide elements based on its characteristics and wide range of related applications. Cerium is the second element in the lanthanide series, and mostly can be found in either +3 or +4 ionisation states. It can be considered one of the rare earth elements with relatively low toxicity and a lot of biological applications depending on its redox (reduction-oxidation) process between the +3/+4 ionisation states and oxygen storage capability. This book focuses on the cerium compounds such as oxides and silicides, with detailed studies about its structures, characterisations and related applications. Chapter One mainly presents some optical characteristics of stoichiometric ceria nanoparticles whether undoped or doped with some other lanthanide elements. Then, some applications of ceria nanoparticles, such as optical nanosensors and solar cell coaters, are discussed based on optical characteristics of CeO2-x. Chapter Two studies the catalytic activity of cerium dioxide (CeO2) included within nanophase (nanocomposite) metal-oxide systems such as Al2O3/cordierite carriers and prototypes of anode materials for SOFCs (based on stabilised zirconia), within different processes of environmental catalysis. CeO2 increases stability of the Ni-Al2O3 catalysts by suppressing surface carbonisation and enhancing resistance to poisoning by sulphur compounds. Cerium dioxide as a modifying additive within the ZnOCuOCeO2/Al2O3/cordierite catalysts is shown to stabilise their operation in the decomposition of methanol by suppressing surface carbonisation, thereby facilitating hydrogen formation as the target product. In Chapter Three, another cerium-dependent compound cerium silicide (CeSix) and its nanowires were investigated over a broad range of different cerium monolayers on Si(110)-16×2 surfaces via scanning, tunnelling, microscopy and spectroscopy. The growth progress of the CeSix nanowires undergoes a coverage-dependent metal-insulator-metal electronic transition, which has never been found in other rare-earth silicide nanowires. Moreover, the insulating CeSix nanowires have been structurally and electronically studied, without lattice distortions with large Coulomb repulsion energy between the filled and empty surface bands. Thus, the insulating phase of atomically precise CeSix nanowires is an electronically driven phase because of its temperature and structure independence. Chapter Four is mainly concerned with some biological applications of ceria nanostructures through the treatment of diseases characterised by increased oxidative stress levels. This chapter offers a study of consumption and occupational exposures, and consequently its toxicology properties are discussed due to the recent applications of nanoceria as a high priority material for toxicological evaluations.
Download or read book Nanomaterials and Plant Potential written by Azamal Husen and published by Springer. This book was released on 2019-03-01 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the latest developments in plant-mediated fabrication of metal and metal-oxide nanoparticles, and their characterization by using a variety of modern techniques. It explores in detail the application of nanoparticles in drug delivery, cancer treatment, catalysis, and as antimicrobial agent, antioxidant and the promoter of plant production and protection. Application of these nanoparticles in plant systems has started only recently and information is still scanty about their possible effects on plant growth and development. Accumulation and translocation of nanoparticles in plants, and the consequent growth response and stress modulation are not well understood. Plants exposed to these particles exhibit both positive and negative effects, depending on the concentration, size, and shape of the nanoparticles. The impact on plant growth and yield is often positive at lower concentrations and negative at higher ones. Exposure to some nanoparticles may improve the free-radical scavenging potential and antioxidant enzymatic activities in plants and alter the micro-RNAs expression that regulate the different morphological, physiological and metabolic processes in plant system, leading to improved plant growth and yields. The nanoparticles also carry out genetic reforms by efficient transfer of DNA or complete plastid genome into the respective plant genome due to their miniscule size and improved site-specific penetration. Moreover, controlled application of nanomaterials in the form of nanofertilizer offers a more synchronized nutrient fluidity with the uptake by the plant exposed, ensuring an increased nutrient availability. This book addresses these issues and many more. It covers fabrication of different/specific nanomaterials and their wide-range application in agriculture sector, encompassing the controlled release of nutrients, nutrient-use efficiency, genetic exchange, production of secondary metabolites, defense mechanisms, and the growth and productivity of plants exposed to different manufactured nanomaterials. The role of nanofertilizers and nano-biosensors for improving plant production and protection and the possible toxicities caused by certain nanomaterials, the aspects that are little explored by now, have also been generously elucidated.

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.
