The electromagnetic shielding properties of several conducting textiles are investigated by means of measurement techniques and numerical calculations. The features and performances of a computational Material Modeling Tool (MMT) are introduced and applied to the calculation of the shielding effectiveness of metallize…
Fuel cells belong to an avant-garde technology family for a wide variety of applications including micro-power, transportation power, stationary power for buildings and other distributed generation applications. The first objective of this contribution is to find a suitable reduced model of a Solid Oxide Fuel Cell (SO…
The kinetics of oxidation of α,β-unsaturated alcohols (allyl alcohol, Crotyl alcohol, Cinnamyl alcohol) by quinaldinium fluorochromate has been studied in aqueous acid medium at 313 K. α,β-unsaturated alcohols were converted to the corresponding acrolein, crotonaldehyde and cinnamaldehyde. The reaction is first order…
For years, many companies or research organizations are concentrating their efforts on further miniaturization and multi-function of devices with high density interconnects. Assembly with 2.5D/3D stacking is one of the most innovative interconnect technologies today, and it is anticipated to be a breakthrough in the n…
Pada penelitian ini telah dilakukan sintesis padatan CaF 2 dan Ca 1-x Cu x F 2 . Padatan Ca 1-x Cu x F 2 disintesis dengan cara doping logam Cu ke dalam padatan CaF 2 (x= 0,025; 0,05; 0,075; 0,1 dan 0,15 mol). Padatan hasil sintesis kemudian dikarakterisasi struktur kristalnya dengan difraktometer sinar-X (XRD). Difra…
Waste plastic of cylinder lattice to liquid fuel production process was performing two step processes. 1st step process was perform muffle furnace with ceramic crucible and 2nd step process was perform glass reactor with condensation unit. Thermal degradation process was performing with furnace and temperature was 410…
Abstract In this paper, we describe preliminary steps in a new approach to make dielectric materials for low voltage monodomain organic field effect transistors to be used in backpanels for displays. A hybrid organic‐inorganic high‐k dielectric material based on oleic acid stabilized titanium oxide nanorods is synthes…
A comprehensive program of integral experiments, largely based on the measurement of reaction rate distributions, was carried out recently in the PROTEUS zero-power research reactor at the Paul Scherrer Institute in Switzerland, employing a fuel lattice resembling that of a supercritical light water reactor. The prese…
ABSTRACT: In this paper the influence of two different sizes of silica particles (micro-silica and nano-silica) was studied on mechanical properties of sulfur and sulfur composite. To improve the structural properties, sulfur was plasticized using dicyclopentadiene (DCPD) and methyl styrene (MSt). Plasticized sulfur c…
Sensor components are increasingly used in electronic applications. One example of such a sensor is a humidity sensor. The attachment process of humidity sensors can be challenging as the sensor structure needs to be open to the environment. The use of solders is often prevented by sensor materials and structures. Con…
Untreated and ethylene glycol (EG)-treated nanosilica powders were synthesized from rice hull ash, and their sorption properties for water vapor were investigated. The morphology, elemental compositions, surface area, and pore structures of the nanopowders were elucidated using scanning electron microscopy (SEM) and n…
The profile of chemical potential of benzene fluid has been investigated using Anisotropic United Atom (AUA) model. A Monte Carlo simulation in canonical ensemble was done to obtain the isotherm of benzene fluid, from which the excess part of chemical potential was calculated. A surge of potential energy is observed d…
We investigated the effects of the additions of Zr and other alloying elements on the mechanical properties and microstructure in Cr-Mo plastic mold steels. The addition of alloying elements changed the microstructure of the normalized samples from the upper bainite to lower bainite due to the increased hardenability.…
The formation of isolated clots of electrons, which determine both the behavior of the flow and its noise properties has been found by means of high-precision system of numerical simulation in the investigation of the dynamics of extended flows of electrons in crossed fields. The received results testify that the very…
This paper investigates the effects of crystallization on the mechanical stability of geopolymers, a particularly important aspect for concrete applications with a view towards durability. Three typical geopolymers are synthesized with Class F fly ash (one blended with 20% slag), and cured under 80oC hydrothermal or a…
New pressurized water reactor (PWR) cross-section libraries were generated for use with the ORIGEN-ARP depletion sequence in the SCALE nuclear analysis code system. These libraries are based on ENDF/B-VII.0 nuclear data and were generated using the two-dimensional depletion sequence, TRITON/NEWT, in SCALE 6.1. The lib…
Warm Mix Asphalt (WMA) provides a viable alternate to Hot Mix Asphalt (HMA) as an airport surfacing and/or structural layer. WMA provides a number of benefits over HMA. Reduced environmental impact (through reduced carbon emissions), increased health and safety (through reduced fume generation), and increased working…
Magnetic fusion development toward DEMO will most likely require a number of fusion nuclear facilities (FNF), intermediate between ITER and DEMO, to test and validate plasma and nuclear technologies and to advance the level of system integration. The FNF mission space is wide, ranging from basic materials research to…
Both Alloy 617 and Alloy 230 have been considered the most promising structural materials for the Very High Temperature Reactor (VHTR). In this study, mechanical properties of both alloys were examined by performing tensile tests at three different strain rates and at temperatures up to 1000°C. This range covers time-…
Kaolins are common geological materials and have high concentrations of kaolinite as well as the clay fraction of tropical and subtropical soils of Brazil. The characterization of kaolin is a proxy of assessing the contribution of kaolinite to important soil chemical and mineralogical attributes. This study evaluated…
