Abstract:
An intense reddish-orange colour radiating Samarium doped Aluminium Calcium borosilicate (BSACS) glasses were synthesized with the help of the melt-quench method to analyze the photoluminescence properties using characterization methods like XRD, FT-IR, photoluminescence (PL) excitation, PL emission, and PL decay. XRD and FT-IR reveal the non-crystalline behavior along with the presence of numerous functional groups in BSACS host glass correspondingly. Under 402 nm excitation, three major peaks were found in the emission spectra which perfectly resembles to 4G5/2 → 6H5/2 (562 nm), 4G5/2

Abstract:
Anisotropic magnetic materials have been proposed over the past twenty years or so as candidates for high density storage, so-called Single-Molecule Magnets (SMMs). These may in future be used to store data at the level of an individual molecule. Separately, isotropic materials may be harnessed for their large magnetocaloric effect which enables them to be used as refrigerants. This can potentially replace the increasingly rare and therefore expensive 3He and 4He currently employed either separately or in 3He-4He dilution refrigerators. This thesis examines the use of lanthanide(III) ions for

Ce travail s'inscrit dans le cadre de la protection de l'environnement et s'intéresse spécifiquement à la dépollution d'effluents aqueux en vue de piéger d'une part les anions nitrate et/ou phosphate, responsables du phénomène d'eutrophisation, mais également le toluène, hydrocarbure couramment rencontré dans les effluents aqueux urbains et industriels ou les eaux naturelles. Le piégeage de ces polluants a été effectué sur des matériaux zéolithiques. Une grande partie des expérimentations utilise un matériau potentiellement efficace pour le piégeage des trois polluants cités plus haut, à savoi

Tidigare undersökningar har delade meningar om huruvida det är en skillnad i användandet av emojier mellan yngre och äldre åldersgrupper. Forskningen har främst fokuserat på användningen av emojier online i sociala kanaler, därav finns det

Dans le but d'etudier les collisions ions-atomes a basse energie, nous avons realise une source d'ions de recul. Ces ions de recul sont produits par impact de faisceaux issus de la sortie moyenne energie du ganil sur une cible gazeuse. Un dispositif electrostatique et magnetique permet d'extraire, de guider et de selectionner ces ions de recul. Nous indiquons la facon d'operer afin de former des faisceaux les plus intenses possible, de bonne qualite optique tout en conservant une faible dispersion en energie.

Abstract:
The development of micro and nano-electromechanical systems (MEMS and NEMS) with entirely new or improved functionalities is typically based on novel or improved designs, materials and fabrication methods. However, today’s micro- and nano-fabrication is restrained by manufacturing paradigms that have been established by the integrated circuit (IC) industry over the past few decades. The exclusive use of IC manufacturing technologies leads to limited material choices, limited design flexibility and consequently to sub-optimal MEMS and NEMS devices.

Indiana University-Purdue University Indianapolis (IUPUI)<br>The etiology of many neurodegenerative diseases is unknown, but a number of studies indicate that a combination of both genetic and environmental factors contribute to the progression of disease. Exposure to environmental metals, such as Mn2+, Fe2+, Cu2+, and Al3+, has been shown to increase cell death that is characteristic of neurodegenerative disorders such as AD, PD, Wilson’s disease and Menkes disease. These metals are important in numerous biological processes in the brain and their homeostasis is regulated through multiple m

Abstract:
The cyanide ligand has frequently been used to prepare clusters with novel magnetic properties due to its ability to provide an efficient pathway for superexchange between metal centers that are bound in an end-to-end fashion. One of the common synthetic approaches in this chemistry is to design suitable cyanide containing precursors and then to react such building blocks with metal complexes consisting of accessible sites. The triphos ligand (triphos: 1,1,1-tris(diphenylphosphinomethyl)ethane) has been employed in this vein to prepare metal complexes, one of which is a five coordinate paramag

The Fe3+ ion is substituted with the same valence of Sc3+ ion to form Ba(Fe1-xScxNb)0.5O3 (x = 0~1) ceramic. (Fe1-xScxNb)O4 is formed by calcination in the first step. Afterwards, BaCO3 is added into the (Fe1-xScxNb)O4 in the second step, and then the complex perovskite structure Ba(Fe1-xScxNb)0.5O3 (x = 0~1) is formed when they were calcined at a high temperature.
