Measurements were made of jump frequencies of 111In/Cd tracer atoms on the\nSn-sublattice in rare-earth tri-stannides having the L12 crystal structure via\nperturbed angular correlation spectroscopy (PAC). Phases studied were Sn3R (R=\nLa, Ce, Pr, Nd, Sm and Gd). Earlier measurements on isostructural rare-earth\ntri-i…
Process simulation are performed in order to simulate the full fabrication process of an alternative nano-flash memory in order to optimise it and to improve the understanding of the dot storage formation. The influence of various parameters (oxidation temperature, nanowire shape) have been investigated.
One of the most important environmental issues for decades to come is the treatment of industrial wastewaters containing salts (sulfates, chlorides, sodium, magnesium ...) which can lead to strong perturbations affecting the fauna and flora when highly concentrated at the discharge point. Different processes used to s…
Background and Aims: Natural radioactivity (NR) is an ubiquitous phenomena and exhibits large geographical variations. Current risk models for radiation-induced leukaemia prediction, which are mainly issued from the epidemiological study of Hiroshima and Nagasaki A-bomb survivors, imply that levels of NR could induce…
A novel class of high flux microfiltration membrane consisting of an electrospun nanofibrous membrane and a conventional non-woven microfibrous support is being presented.The nanofibrous membrane was fabricated by electrospinning of poly (vinyl alcohol) (PVA) followed by chemical cross-linking with glutaraldehyde (GA)…
This report, issued in the frame of task LP2-E.2 of the AdP PAR2008-09 assigned to CIRTEN , outlines the work performed during the period of time spent at the CEA Cadarache Research Centre in the Jules Horowitz Reactor (JHR) project. A thermal hydraulic and neutronic model of JHR core is presented and implemented thro…
The Phase I LHC Collimation System Upgrade could include moving part of the Betatron Cleaning from LHC Point 7 to Point 3 to improve both operation flexibility and intensity reach. In addition, the partial relocation of beam losses from the current Betatron cleaning region at Point 7 will mitigate the risks of Single…

Eleven ligands derived from mono-, bis- and tristhiosemicarbazone were designed and synthesized. These ligands exhibit different number of donor atoms, terminal substituents in the thiosemicarbazone strands or central linkers. The electrochemical oxidation of a metal anode (Mn, Fe, Co, Ni, Cu, Ag, Zn, Cd, Sn and Pb) i…
Lo scopo del presente documento è quello di documentare le attività svolte e le implicazioni per il nostro paese derivanti dalla partecipazione alle riunioni internazionali di ARIUS ed ERDO WG. L'obiettivo iniziale di ARIUS è stato quello di organizzare studi su aspetti tecnici, legali, associati allo stoccaggio e sma…
Recent developments in the pharmaceutical industry have led to an enormous increase in the variety of dosage forms available to the formulator. The stability of active compounds as well as the target site of the active material will govern the selection of the dosage form which is used in a given case. The design of p…
Researches concerning renewable energy sources and wastes recycling are strategic to ensure energetic and environmental sustainability of the planet. In this scenario, biofuels (including bioethanol) have attracted increasing attention. Most ethanol is currently produced from sugar- and starch-based feedstocks, such a…
With growing concern in obtaining clean and renewable energy, many works in bioenergy has been developed in order to obtain substantial gains for the environment. Due to the large environmental impact associated to the use of fossil fuels, ethanol production from lignocellulosic materia lhas been widely explored, aimi…
Diesel engine fuel hose return line is considered as a low pressure line and consists of two layers. The inner layer is used to carry the excess fuel, thereby hose material shall have resistance to fuel and its residues. The outer layer is used to protect inner layer from heat, ozone and oil spillage, thereby outer co…
When submerging a pure metal or an alloy in an aqueous solution, a migration of metallic ions between the solid phase and the aqueous phase starts immediately. In fact, it is a constant exchange of metallic ions in which the prevailing speed will be the one leading to a decrease of the free energy (W) of the system.
The hemicellulose xylan constitutes the major non-cellulosic component of plant secondary cell walls. It has been shown that xylan adsorbs to cellulose fibres and also covalently binds a carbon moiety of lignin [ 1 , 2 ]. Eucalyptus is an important hardwood tree genus used in the pulp and paper industry and has potent…
Isotopic Engineering (IE) is a generic term designating targeted use of specific isotopes to modify physical, chemical and technological properties of materials.Stable isotopes of the same chemical element differ in mass, diffusivity, magnetic properties and have different vibrational frequencies in crystalline matric…
In many problems from the field of textile engineering (e.g. fabric folding, motion of the sewing thread), it is necessary to investigate the motion of the objects in dynamic conditions, taking into consideration the influence of the forces of inertia and changing in the time boundary conditions. This article deals wi…
Back Cover: Cell dynamics simulation of block copolymer - nanoparticle composites is presented. The background shows pure block copolymer lamellar system, the four insets depict the different nanoparticles inside block copolymer lamellae. Further details can be found in the article by M. Pinna, I. Pagonabarraga, and A…
Abstract Abstract. A new coordination polymer derived from CdII with pyrazine has been synthesized and characterized by elemental analysis, IR,1H, and 13C{1H} NMR spectroscopy and studied by thermal analyses. The structure of [{Cd(pyz)2(OAc)}n]·n(ClO4) (1) was determined byX‐ray diffraction analysis. It crystallizes i…
