The evolution of the clad temperature during a Reactivity Initiated Accident plays a key role in the accidental sequence because it strongly influences the rod mechanical resistance against failure. The present study aimed at quantifying the heat transfer in NSRR experiments. Transient boiling curves were determined b…
A stable Fe23B6-type phase formed in a nanocomposite soft magnetic alloy Fe40Co40Nb4B13Ge2Cu1 after thermal treatment was investigated. The primary crystallization temperature and second crystallization temperature for this alloy were determined to be 405 and 740°C, respectively. After annealing the sample at 820°C fo…
In ablator shell fabrication, trace elements and impurities are introduced in the deposition and the pyrolysis process, which must be controlled below a critical level. However, it is the opacity, not the individual elements, which matters in an Inertial Confinement Fusion (ICF) implosion. Radiography measures the opa…
Abstract The objective of this work is to provide additional insight on the influence of (2E)‐3‐amino‐2‐phenylazo‐but‐2‐enenitrile and its derivative as corrosion inhibitors for copper in 0.5 M HNO 3 . Electrochemical techniques (potentiodynamic polarization, polarization resistance and impedance spectroscopy) as well…
A finite simple shear deformation of an elastic solid induces unequal normal stresses. This nonlinear phenomenon, known as the Poynting effect, is governed by a universal relation between shear strain and first normal stresses difference, valid for nondissipative isotropic elastic materials. We provide the first exper…
Abstract Bi‐Fe‐O thin films are grown by liquid‐injection metal‐organic (MO)CVD on (001) SrTiO 3 substrates using two different bismuth precursors, Bi(tmhd) 3 and Bi(mmp) 3 . The precursor Bi(mmp) 3 is found to be more effective for Bi incorporation in the films. Epitaxial BiFeO 3 films are obtained and no evidence fo…
Honeycomb-like macrostructured carbons with well-defined microporosity have been prepared from the microwave popping of maize followed by thermal carbonization. The obtained carbon material shows good catalytic activity over oxidative dehydrogenation of ethylbenzene to styrene.
Two methods for extracting information from first-order reversal curves (FORCs) obtained on low coercivity samples are presented. The proportion of reversibility as a function of applied field can be extracted by calculating the ratio of the initial slope of each FORC to the susceptibility on the major hysteresis loop…
A method for fabrication of highly (100)-oriented Pb(Zr0.2Ti0.8)O3 (PZT) thin films by rf magnetron sputtering with a special buffer of PbOx (RFMS-SBP) was developed. With this method, highly (100)-oriented Pb(Zr0.2Ti0.8)O3 thin films were prepared on the PbOx∕Pt(111)∕Ti∕SiO2∕Si(100) substrates, and the preferential (…
An enhanced macromolecular nanofiber network and its implications have been developed by employing the understanding of its formation with an emphasis on its topological aspect. Using agarose aqueous solution as a typical example, the macromolecular nanofiber network of soft functional materials has been clearly visua…
High altitude rivers in European mountains show a large diversity of benthic diatom assemblages. Diatoms were studied from rivers of the Alps, the Pyrenees, the Massif-Central and the Iberic system. The study area spread across four countries, Italy, France, Switzerland and Spain. Since 2000, the European Water Framew…
A precursor solution containing poly(vinyl alcohol) and a calcium phosphate sol is used to produce fibers of hydroxyapatite. The mixture is electrospun at a voltage of 20 kV and the resultant structure is calcined at 600°C for 6 h. Experiments were conducted for polymer molecular weight ( M W ) between 9500 and 155 00…

Monofunctionalized polyamide-based dendrimers containing either a terminal azide or alkyne moiety have been designed and synthesized via a convergent synthetic approach. The monofunctionalization allows for the single attachment of a functional moiety in quantitative yields by using 1,3-dipolar cycloadditions, thereby…
Diatoms produce extracellular polymeric substances (EPS), which mainly consist of carbohydrates and may form different morphological structures. We studied the localization and structure of EPS secreted by 17 diatom species that were isolated from epilithic biofilms from the littoral zone of Lake Constance (Germany).…
The adsorption process of beta-lactoglobulin on the polyethersulfone-coated surface has been investigated using a quartz crystal microbalance with dissipation monitoring (QCM-D), which allowed simultaneous measurements of frequency and energy dissipation changes caused by the formation of a beta-lactoglobulin layer du…
The ferromagnetic resonance (FMR) behaviors for Ni80Fe20 Permalloy films with a wide thickness range from 30to360nm were investigated. The FMR measurements were performed by a vector network analyzer (VNA) technique with scanning frequency at a specified external field. The measured frequency response was fitted well…
Cassava starches are widely used in the production of biodegradable films, but their resistance to humidity migration is very low. In this work, commercial cassava starch films were studied and classified according to their physicochemical properties. A nondestructive method for water vapor permeability determination,…

We have performed first principles calculations of Fe-doped BaTiO 3 and SrTiO 3 . Dopant formation energy, structure distortion, band structure and density of states have been computed. The dopant formation energy is found to be 6.8 eV and 6.5 eV for Fe-doped BaTiO 3 and SrTiO 3 respectively. The distances between Fe…
