The small punch (SP) test is one of the small specimen test techniques, and standardization of the SP test method for evaluating the mechanical properties of metallic materials is in progress. In this study, the impact transition temperature of reactor pressure vessel steels (RPV) in nuclear power plants was estimated…
Seven new different thermo-insulating materials based on wool and /or skin wastes were obtained. To emphasize this capability, the effective thermal diffusivities were determined at a material moisture content of 10%, in a temperature range of 10 to 40oC. Depending on the material composition, the results showed that…
In this paper, a new method is proposed to trap the light inside thin film solar cells resulting in higher absorption in these cells. In this method, a continuous metasurface is used inside the cell to divert the sunlight in such a way that it experiences the total internal reflection when reflecting back to the surfa…
Abstract Decommissioning of Nuclear Power Plant is a long-term project during which generations are expected to change. Therefore, it is necessary to appropriately transfer knowledge, technology and skills to the next generation. In recent years, in the world of decommissioning, attempts have been made to apply advanc…
The photonic properties of glass ceramics (GCs) are often enabled by encapsulating nanocrystals (NCs) and doped transition metal ions (TMIs). However, it is difficult to probe the optics-related effect between the host NCs’ band structure and doped TMIs’ d - d orbitals. Herein, perovskite-type K Z n F 3 : N i N C s in…
The aim of this study was to investigate the influence of different process parameters as chemical composition, the pH value and immersion time on the corrosion of the some TiMoNb alloys, using different electrochemical techniques such as: cyclic voltammetry, open circuit potential (OCP) measurement, polarization curv…
Electrospinning is a promising technique to generate scaffolds for delivery systems and nerve tissue engineering. This study aimed to investigate the suitability of polyethylene glycol (PEG) as an agent to prolong circulation time in the delivery of nerve growth factor (NGF) encapsulated into polycaprolactone (PCL) el…
The properties of bonded magnetic materials (RE-M-B /polymer magnetic composites) depend not only on the magnetic properties of powder, but also on the parameters of the consolidation process and the type of binder. Increasing the binder content in RE-M-B /polymer composites could be very beneficial from the cor-rosio…
We present in this paper the effects of Dzyaloshinskii–Moriya (DM) magneto–electric coupling between ferroelectric and magnetic interface atomic layers in a superlattice formed by alternate magnetic and ferroelectric films. We consider two cases: magnetic and ferroelectric films have the simple cubic lattice and the t…
Abstract Linear low density polyethylene (LLDPE)‐date pit composites incorporated with different flame retardants were synthesized by extrusion and casted into shape by injection moulding. Several additive type flame retardants viz. Ammonium polyphosphate (APP), Melamine phosphate (MP), Ammonium dihydrogen orthophosph…
We experimentally study the Mn substitution effect on thermoelectric properties in a full-Heusler alloy, ${\mathrm{Fe}}_{2}\mathrm{TiSi}$. By employing molecular beam epitaxy, homogeneous and $L{2}_{1}$-ordered ${\mathrm{Fe}}_{2}{\mathrm{Ti}}_{1\ensuremath{-}x}{\mathrm{Mn}}_{x}\mathrm{Si}$ epilayers are achieved. The…
Hydrostatic testing, or hydrotesting, has been widely used as a stress corrosion cracking management method in the pipeline industry, particularly in gas pipelines. Although the technique has been very useful in the prevention of operational failures, it is known that these high pressures can produce significant plast…
Abstract Methyl benzoate functionalized phenylenediamine derivatives with the methoxycarbonyl groups at the ortho ‐, meta ‐ and para ‐positions of amino group were synthesized via palladium‐catalyzed Buchwald‐Hartwig reaction and copper‐catalyzed Ullmann amination. Crystallographic analysis unraveled the presences of…
A new synthesis strategy intended to increase apatite available surface groups for the covalent functionalization with (bio)molecules was developed. To that purpose, hydroxyapatite nanoparticles (Ap) were synthesized and terminated with 3-phosphonopropionic acid (PPA) yielding Ap with surface bound propionic acid thro…
The efficiency of strain-mediated magnetoelectric composites is heavily reliant on the effectiveness of strain transfer between the different constituents. Many analytical and experimental studies have trialed various materials, geometries, and boundary conditions reporting the effect of these attributes on the magnet…
There has been a rapid increase in polymeric materials and they have become a part of human life, which is probably due to their potential applications and their functional characteristics. However, the use of polymeric systems that are nondegradables induces serious problems to human life as well as to the environmen…
Purpose The purpose of this paper is to reveal the mechanism of nitrite (NO2−) for the surface passivation of carbon steels in acidic environments through investigating the influences of 0.01 mol/L NaNO2addition on the corrosion and passivation behaviors of Q235 carbon steel in acidic phosphate buffer (APB) solutions…
Abstract Upconversion phosphors have numerous advantages compared to down conversion phosphor materials, such as a weak background interface, low excitation energy, sharp emission lines, and long lifetimes. Conventionally, blue laser diodes are used to obtain strong white light by combining green‐ and red‐emitting pho…
Tip-enhanced spectroscopy techniques, in particular tip-enhanced Raman spectroscopy (TERS), rely on a localized surface plasmon resonance (LSPR). This LSPR depends on the near field antenna, its material and shape, and the surrounding medium with respect to its relative permittivity and the volume fraction of the opti…
The present study aimed to investigate the physico-chemical properties of new cellulosic fiber obtained from the bark of Melia Azedarach tree. The investigation outcomes revealed that, the cellulose content, crystallinity index and density of Melia Azedarach Fiber (MAF) were determined as 66.5 wt.%, 45.45% and 950 Kg/…
