During a hypothetical severe accident in a Pressurized Light Water Reactor, the hot molten material mixture (corium) issuingfrom the degraded reactor core may generate a steam explosion if it comes ...
This paper presents the findings of an experimental study of how ageing temperature affects the pseudoelasticity (PE) and its phases of Shape Memory Alloy (SMA). These have been examined by means of tensile testing machine and X-ray diffraction (XRD). By increasing the ageing temperature (constant ageing time) from 35…
We have studied both single and polycrystalline samples of Eu 1− x K x Fe 2 As 2 with x = 0, 0.35, 0.45 and 0.5 by means of electrical resistivity, susceptibility as well as specific heat measurements. Above 40 K, the susceptibility of single crystalline EuFe 2 As 2 , measured in fields applied along and perpendicular…
The determination of CEC and exchangeable bases in calcareous soils has always been very difficult, because partial dissolution of the phases (e.g. CaCO 3 ) is observed in these matrices as a result of interaction with the exchange solution rich in electrolytes. The proposed method foresees, on 10 g of soil, a saturat…
The importance of well-developed constitutive models for predicting deformation behavior of materials at high strain rates cannot be overstated. The study and development of these constitutive models is pertinent to several fields, yet the test methods utilized to probe this high strain-rate realm are limited in both…
A series of (100-x)(GeTe4)-xGa (x=0, 5, 10 mol%) far infrared transmitting chalcogenide glasses is prepared by the traditional melt-quenching method. In this paper, the differential thermal analysis (DTA), visible/near-infrared absorption spectroscopy, infrared transmission spectra are adopted to analyze composition,…
In this paper, dry sliding wear and corrosion behavior of Cu + 13wt% Al + 3.8 wt% Ni was prepared by powder metallurgy. Dry sliding wear has been studied based on pin on disk at constant velocity and constant sliding distance .Corrosion behavior in 5 wt% NaOH solution based up on potentiostatic ( Tafel ) has been pres…
Extraction and bleaching of citric acid- and pepsin-soluble collagens (ASC and PSC, respectively) from shark (Isurus oxyrinchus) skin and muscle were investigated. The optimal sodium hydroxide concentration for extraction was 0.3 M and the optimal treatment time for removal of foreign material was 9 h. The optimal sod…
Recently, number of studies for porous silicon have been investigated by many researchers. Multistructured porous silicon (PSi), distributed Bragg reflector (DBR) PSi, has been a topic of interest, because of its unique optical properties. DBR PSi were prepared by an electrochemical etch of P++-type silicon wafer of r…
The double-layer capacitor (DLC) is a low voltage device exhibiting an extremely high capacitance value in comparison with other capacitor technologies of similar physical size. It's also a promising device for certain power electronic application as energy storage. In this work, a three RC branch equivalent circuit i…
A mill trial was performed in a kraft paper mill in order to evaluate the possibility of utilizing dual polymer dry strength aids system consisting of cationic PVAm and anionic PAM. It was found that the cationic PVAm - anionic PAM dry strength additives can improve paper strength without significantly disturbing the…

Carbon nanotubes (CNTs) are a family of all-carbon quasi one-dimensional nanomaterials that are highly hydrophobic and typically aggregated in bundles. Recent accomplishments in dispersing CNTs in aqueous solutions open possibilities for their new applications in biomedicine. In many occasions, biological and biomedic…
Time-dependent density functional theory quantum mechanical and pseudo-atomistic Monte Carlo statistical mechanical computations are used to guide the systematic improvement of organic electro-optic materials. In particular, the dependence of molecular first hyperpolarizability upon dielectric permittivity and optical…
Uses that relate to surface properties dominate the silicone industry. Since only aliphatic fluorocarbon-based materials have lower surface energies than conventional silicones such as polydimethylsiloxane (PDMS), it can be expected that fluorocarbon-modified silicones, i.e. fluorosilicones, would exhibit interesting…
