The CaCu3TiO12 (CCTO) has a high potential for use in various technological applications, among these dielectric and varistors. The Ca2Cu2Ti4O12 ceramics (with two CCTO and CaTiO3 phases) having a good coefficient of non-linearity (a) when compared with phase pure CCTO which enhances its application as a varistor, how…

Les tapis de nanotubes de carbone verticalement alignés sont des candidats potentiels pour des applications telles que les interconnexions ou les matériaux d'interface thermique. Ce travail de recherche porte sur la synthèse de tapis de nanotubes de carbone alignés selon le procédé de dépôt chimique en phase vapeur (C…
Le marché des diodes électroluminescentes (LEDs) de puissance est en perpétuelle croissance depuis une vingtaine d’années. Le marché de l’éclairage évolue car les besoins ont changé : nous souhaitons, par exemple, aujourd’hui réduire la consommation électrique, ou avoir des éclairages plus flexibles (couleur, cycle d’…
Les composants d’électronique de puissance ont (et vont encore avoir !) eu une grande influence sur les secteurs de l'énergie et des transports. Ces pièces sont notamment constitués d’assemblages céramique –cuivre pour lesquels la tenue mécanique doit être maîtrisée afin de garantir dans le future une durabilité d’env…
We study how the thermodynamic properties of the Triangular Plaquette Model (TPM) are influenced by the addition of extra interactions. The thermodynamics of the original TPM is trivial, while its dynamics is glassy, as usual in Kinetically Constrained Models. As soon as we generalize the model to include additional i…
Melia Bensussen worked closely with Joseph Papp as an associate artist at the New York Shakespeare Festival. She has directed at dozens of New York and regional theatres, including Oregon Shakespeare Festival, North Caro lina Shakespeare Festival, Heart of America Shakespeare Festival, Cleveland Playhouse, and Playwr…
A weekly roundup of information on newly offered instrumentation, apparatus, and laboratory materials of potential interest to researchers.
Abstract Cover: Antero-medial views of representative FE models illustrating maximum principal strain and contours of surface element failure (i.e., εmax > 1.41%). The FE predicted torsional strength corresponded to the torque at which 10% of the surface elements had failed. In general, the location of element failure…
Smart Dendritic Fluorescent Organogels A new fluorescent dendritic organogel based on a poly(benzyl ether) dendron was developed that exhibited gelation-induced enhanced fluorescence emission properties. Most interestingly, these dendritic organogels exhibited multiple stimuli-responsive behaviors upon exposure to env…
Depolymerization Linear polysiloxanes with tunable molecular weights can be obtained via a facile thiol-ene reaction that serves as a promising complement to traditional ring-opening polymerization. The reaction involves selective oxidation of sulfides into sulfones by using an inexpensive reagent under safe and mild…
Dicyclopentadiene-maleic acid monoester (DCPDMA) was synthesized and was used as monomer to synthesize the styrene /DCPDMA copolymer (poly-St / DCPDMA) by solution polymerization. Reaction conditions including esterification temperature, reaction time, and molar ratio of starting materials, polymerization temperature…

Abstract: The concept of disposal of high radioactive waste and spent nuclear fuel described in this paper is based on world famous programs for final disposal in a deep geological facility. The concept of deep geological radioactive waste, in crystalline rocks that would ensure long-term isolation of radionuclides an…
The ‘visual’ inspection should provide much of the data required for writing either catalogue entries or condition reports, but in many cases it will need to be amplified by scientific analysis to refine the descriptions o f the objects. Thus, for instance: ‘Copper alloy inlaid with white and yellow metal wires’ can b…
The subject of this thesis is the numerical modeling of the behavior of plane reinforced concrete frame structures under long-term load with the purpose of qualitative and quantitative analysis of the influence of stiffness changes of these structures, as an effect of the occurrence of cracks, as well as creep and shr…
The ground-state 4f fine-structure levels in the intrinsic optical transition gaps between the 2p and 5d orbitals of lanthanide sesquioxides (Ln2O3, Ln=La...Lu) were calculated by a two-way crossover search for the U parameters for DFT+U calculations. The original 4f-shell potential perturbation in the linear response…
We report direct evidence of two mechanisms responsible for the excitation of optically active Er3+ ions in GaN epilayers grown by metal-organic chemical vapor deposition. These mechanisms, resonant excitation via the higher-lying inner 4f shell transitions and band-to-band excitation of the semiconductor host, lead t…
Este trabalho tem como objetivo estudar o comportamento da transferência de calor em polpa de jaca acondicionada em recipiente cilíndrico. O estudo apresenta a solução para a equação de difusão com condição de contorno de primeiro tipo variável. Foi desenvolvida uma modelagem físico-matemática para solução de um probl…
The present work examines the effects of high frequency induction heating on shape memory alloy (SMA) components with arbitrary geometries. SMA actuators deliver high forces but are compact and reliable, making them ideal for consideration in aerospace applications. One disadvantage of these thermally driven actuators…
