The Lead cooled Fast reactor is a reactor design option selected within GEN-IV initiative. GEN-IV reactor concepts have to fulfill four strategic goals, namely: sustainability, economics, safety and reliability, proliferation resistance and physical protection. Fast spectrum nuclear reactors enable a much more reducti…
ENEA asked CSM to perform a preliminary characterization on EP302 austenitic steel. CSM has been asked to manufacture one ingot EP302 austenitic stainless steel, to manufacture 15 mm thick hot rolled plates, and to assess microstructure and properties of these plates after a final heat treatment in order to optimize t…
Silicon strip detectors are fast, cost-effective and have an excellent spatial resolution.They are widely used in many high-energy physics experiments. Modern high energyphysics experiments impose harsh operation conditions on the detectors, e.g., of LHCexperiments. The high radiation doses cause the detectors to even…
This report, carried out at the Dipartimento di Ingegneria Meccanica, Nucleare e della Produzione (DIMNP) of the University of Pisa in collaboration with ENEA Bologna Research Centre, illustrates preliminary numerical results and the model for fuel dispersion in a LFR reactor types, i.e. the MYRRHA FASTEF reactor. \nT…
Il presente documento riporta la Specifica Tecnica di fornitura, installazione e collaudo dell’impianto a metallo liquido pesante (piombo) HELENA, presso il C.R. ENEA del Brasimone.
Eutectics are mixtures of at least two compounds with a unique property that such system has a lower melting temperature than that of either constituent alone. This decrease in melting point can be scrutinized profoundly from thermodynamics theory which suggests that there is an increase in total entropy of the system…
Interaction of electromagnetic radiation and a flat-heterogeneous slap (coverage) which divides two homogeneous dielectric spaces is examined. For determination of reflection and transparency coefficient impendency method is used. The analysis of results and filter property of the stratified nanocoverages is obtained.
Ever-increasing energy requirement and exhaustion of fossil fuels demands improving efficiency of energy usage as well as seeking sustainable and renewable resources. Energy storage capacitors are devices that could take this responsibility, and have been the focus of increasing attention due to their advantages such…
Bislang erfolgte die Berechnung von Verzahnungskorrekturen in Planetengetrieben für einen bestimmten Betriebszustand.\nDa jedoch die Lasten in der Praxis schwanken, ist es erforderlich, die Verzahnungskorrekturen für das vorliegende\nLastkollektiv zu bestimmen. Auch die Lagerkräfte stellen sich für eine korrigierte Ve…
This research strived to examine the potential for carbon fibre to improve the strength characteristics of ceramic water filters (CWFs) to improve their length of use in the field while maintaining, or improving, existing flow and bacteria attenuation capabilities. Model-scale CWF discs were made exploring several con…
We present experimental and theoretical studies of sp3 materials, alkaline-earth-metal (AEM) disilicides, disilane (Si2H6) and carbon at high pressure. First, we study the AEM disilicides and in particular the case of a layered phase of BaSi2 which has an hexagonal structure with sp3 bonding of the silicon atoms. This…
Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans the biological, physical, and social sciences.
Modern charge-density analysis, edited by C. Gatti and P. Macchi, Berlin, Springer, 2012, xxiii + 783 pp., ISBN 978-90-481-3835-7 In 1968 Coppens and Hamilton wrote (1): ‘The recent interest in dev...
The fluorescence spectra of the porous silicon modified by water solutions of biologically active materials and materials of biological origin are recorded as well as the fluorescence spectra of the porous silicon modified by lecithin monolayers grown on the surface of water solutions of the biologically active materi…
Odonata apresenta alta diversidade de espécies nas regiões tropicais, no entanto, ainda há grandes lacunas de conhecimento em muitos biomas, incluindo a floresta Amazônica. A maioria dos estudos realizados com Odonata na região Neotropical tem como foco os adultos, dessa forma, a taxonomia e biologia das formas imatur…
It is known that reduced sulfur compounds (such as thiocyanate and thiosulfate) can accelerate active corrosion of austenitic stainless steel in acid solutions, but before we started this project the mechanism of acceleration was largely unclear. This work combined electrochemical measurements and analysis using scann…
The article describes the methods of mathematical modeling, use of which is desirable to select the optimal process parameters for making castings, particularly in the design phase of mold technology.
Circular bars of the Zn-22Al-2Cu alloy were prepared by utilizing the semi continuous vertical casting technique. Solid as cast showed high values in the mechanical strength (497 MPa) and hardness (71 RB). The micro structure of the bars consisted of equiaxed dendrites with eutectoidal composition surrounded by eutect…
UV cured epoxy systems represent complementary technology to the established heat cured epoxy systems for coating, adhesion and encapsulation of electronic devices. The UV cured epoxy systems offer significant benefits in terms of fast cure and thus very short production cycle time; low stress and better colour due to…
Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance. It provides a platform for rapid publication of quality research papers, reviews and ch…
