We have investigated the combined effects of a multiplicative noise and nonlinear conductivity on the charge density wave (CDW) dynamics of the quasi-one dimensional conductor Rb0.30MoO3. When the amplitude of a bipolar rectangular voltage pulse excitation is modulated by a multiplicative Gaussian white noise perturba…

Vengono presentate le modalità di effettuazione della caratterizzazione radiologica dei materiali a seguito dello smantellamento dell'impianto nucleare RB-3. \nLa Revisione 1 comprensiva di Addendum è stato elaborata sulla base delle indicazioni emerse nell'incontro del 25/1/2013.
Naturliche Vanadat-abhangige Bromoperoxidasen aus marinen Algen enthalten in den peripharen Bereichen der Proteinmatrix partiell bromierte Tyrosylreste. Im aktiven Zentrum solcher Peroxidasen, die mit Bromid versetzt wurden, werden Brom-Vanadium-Abstande zwischen 3.6 und 4.1 A gefunden. EXAFS-Untersuchungen ergaben ei…
This work was carried out at the end of the CDT/FASTEF EU FP7 project. The main outcome of the WP2 Task 2.2 is represented by the Deliverable D2.2 (ENEA Technical Report UTFISSM-P9P0-020) that describes the rationale of the MYRRHA-FASTEF FA / core design, together with its detailed analyses (neutronic, TH, shielding a…
La génération de surfaces présentant des nanostructurations de surface variées et modulables est l’objectif principal de ce travail. L’auto-assemblage de copolymères à bloc ou de nanoparticules d’or a été privilégié, et nécessite pour se faire de moduler finement les interactions aux interfaces substrat/ matériaux dép…
The nonlinear rheology of a soft glassy material is captured by its constitutive relation, shear stress vs shear rate, which is most generally obtained by sweeping up or down the shear rate over a finite temporal window. For a huge amount of complex fluids, the up and down sweeps do not superimpose and define a rheolo…
Long fiber composite materials can be elaborated by Liquid Composite Molding (LCM), a family of processes where fibrous preforms are injected by a low viscosity resin. During this process, we have to pay particular attention to the void formation inside the preform because it could modify the material final characteri…
Quantitative understanding of the fracture toughness of metallic glasses, including the associated ductile-to-brittle transitions, is not yet available. Here we use a simple model of plastic deformation in glasses, coupled to an advanced Eulerian level set formulation for solving complex free boundary problems, to cal…
IATE Axe 2 : Structuration sous contraintes des agropolymères et réactivité des poudres
Electronic nematicity, which breaks the C$_4$ rotational symmetry of underlying lattice, has been observed by various techniques in underdoped ferropnictides, accompanying the structural transition from tetragonal to orthorhombic. Recent magnetic torque measurements suggest that the electronic nematicity develops abov…
This task supports the allowance of technical assistance to fuel-cell component and system developers as directed by the DOE. This task includes testing of novel materials and participation in the further development and validation of single cell test protocols. This task also covers technical assistance to DOE Workin…
Thanks to generally less stringent cost constraints, portable power fuel cells, the direct methanol fuel cell (DMFC) in particular, promise earlier market penetration than higher power polymer electrolyte fuel cells (PEFCs) for the automotive and stationary applications. However, a large-scale commercialization of DMF…
Tables 2 and 3 in the paper by Tumanov et al. [(2010), Acta Cryst. B 66 , 458–471] are corrected.
In the present scenario, Ordinary Portland Cement (OPC) is the most widely used binder in concrete. Production of OPC requires large amount of energy and has a large carbon footprint, emitting approximately 5% of global CO2 emissions annually, which works out to one ton of CO2 emission for every one ton of production…
Assessing the performance of spent (used) nuclear fuel in geological repository requires quantification of time-dependent phenomena that may influence its behavior on a time-scale up to millions of years. A high-level waste repository environment will be a dynamic redox system because of the time-dependent generation…
Sequential MCMC methods are a class of stochastic numerical integration methods for target measures $\\mu$ which cannot feasibly be attacked directly with standard MCMC methods due to the presence of multiple well-separated modes. The basic idea is to approximate the target distribution $\\mu$ with a sequence of distr…
In this paper we published force constants for Si diamond up to fifth neighbor shells for the harmonic, and first neighbor shells for the cubic and quartic force constants. Here we would like to report an error in the published quartic coefficients and provide a better set, which was used in our molecular dynamics sim…
A novel silver-containing compound, bis(benzylamino)silver(I) benzylcarbamate, with an unusual molecular structure is easily synthesized by the reaction of benzylammonium benzylcarbamate and silver oxide. It crystallizes in the triclinic crystal system with the space group P ̅1 with a = 5.2006 (5), b = 14.6298 (15), c…
A 48-year-old male patient was admitted to the emergency department with complaining of an acute onset of dyspnea. A chest X-ray demonstrated pulmonary edema while echocardiography revealed a giant mass originating from the mitral valve orifice, which was severely blocking the atrioventricular flow. The patient underw…
