This paper presents a multi-functional frequency selective surface (FSS)based on varactor diode and PIN diode loading. It can be realized that when the varactor diode is not loaded with voltage and the PIN is in the on state, the frequency selective surface(FSS) exhibits strong transmittance at 4 GHz, and when the PIN…
Gold (AuNP) and silver (AgNP) nanoparticles have been incorporated into many therapeutic and diagnostic applications. However, previous studies revealed toxic properties as well as the hormesis phenomenon of many nanoparticles in different biological models. To evaluate the effects of low concentrations of AuNP and Ag…
Abstract Durability of fuel cell is still a major concern for successful progress and commercialization of proton exchange membrane fuel cell (PEMFC) technology. One of the factors affecting durability of PEMFC is the impurities present in atmospheric air that is fed at cathode which degrades the PEMFC performance. Co…
Abstract An ionic liquid (IL)‐based solvothermal method is employed to prepare single‐phase, luminescent, cubic rare‐earth doped and silica‐coated BaF2 nanomaterials. High energy transfer efficiency (∼60%) from Ce3+ to Tb3+ for BaF2:Ce3+/Tb3+ nanoparticles dispersed in DMSO solution is observed. Furthermore, for the f…
In the paper, corrosion behavior of T91 steel in different concentrations of NaHSO 3 solution was studied in combination with scanning electron microscope (SEM) and electrochemical measurements. The results showed that the steel exhibited active anodic dissolution characteristics in the solution, and NaHSO 3 concentra…
Abstract Nanometric gaps in plasmonic structures can lead to huge optical near fields and, related, to strongly enhanced interaction of molecules and light. Nanocavities formed by sphere-on-film or cube-on-film systems were recently established as promising systems, eventually reaching the strong coupling regime. Howe…
One of the important steps in the fabrication of semiconductor memory devices is the deposition of ultrathin silicon nitride films with uniform film thickness and electrical properties. Such high-quality films have made atomic level control during deposition a necessity and can be achieved via atomic layer deposition…
During energization of no – load transformers, a high and peaky current flow on the primary side which has rich second harmonics. This current is magnetising inrush current and it is generated when transformer core is driven deep into saturation. This current has various disturbances on transformer attribute; reduced…
Spinal fusion (SF) surgery relies on medical hardware such as screws, cages and rods, complemented by bone graft or substitute, to stabilize the interventioned spine and achieve adequate bone ingrowth. SF is technically demanding, lengthy and expensive. Advances in material science and processing technologies, propose…
Nanomechanical properties and interphase dimensions of PVA bionanocomposites reinforced with halloysite nanotubes (HNTs) and Cloisite 30B montmorillonite (MMT) were evaluated by means of peak force quantitative nanomechanical mapping (PFQNM). A three-phase theoretical composite model was established based on hard-core…
Purpose To (a) characterize the fundamental optical and dosimetric properties of the storage phosphor europium‐doped potassium chloride for quantitative proton dosimetry, and (b) investigate if its dose radiation response can be described by an analytic radiation transport model. Methods Cylindrical KCl:Eu2+ dosimeter…
The under-deposit corrosion behavior and mechanism of aluminum brass (HAl77-2) were investigated in artificial seawater with a custom double electrolytic cell. The experiments included linear polarization, electrochemical impedance spectroscopy, and multielectrode arrays analysis. The electrochemical results revealed…
A modern approach to nuclear energy involves reprocessing like transmutations of spent nuclear fuel products to reduce their radiotoxicity and time needed for their storage. For this purpose, they are immobilized in inert matrices made of zirconia and can be "burned" in fast neutron reactor or Accelerator Driven Syste…
The presence of in-gap states, especially deep ones, that act as recombination centers in solar-cell absorbers influence the phototransport properties of the films, and thus, strongly affect the performance of the corresponding solar cells. The type and density of such defects is influenced by the deposition process.…
The Hopkinson pressure bar is widely used to measure the reflected pressure of blast waves over a short distance. However, dispersion effects will occur when the elastic stress waves propagate in the pressure bar due to lateral inertia, and there will be errors between the signals obtained from the sensors and the act…
PURPOSE: A new phantom, designed and manufactured for modulation transfer function (MTF) calculations is presented in this work. The phantom has a star-bar pattern and is manufactured in stainless steel. Modulation transfer function determinations are carried out with the new phantom and with an edge phantom to compar…
Abstract 5‐(4‐(Het)arylphenyl)‐2,2′‐bipyridine‐6‐carboxylic acids were synthesized as ligands for the neutral lanthanide complexes by using the “1,2,4‐triazine” approach and Suzuki or Stille cross‐coupling reaction with intermediate 5‐(4‐bromophenyl)‐2,2′‐bipyridine‐6‐carbonitrile. The neutral europium complexes of th…
Single crystals of KScP2O7, potassium scandium diphosphate, were grown in a borate flux. The title compound crystallizes isotypically with KAlP2O7 in space-group type P21/c, Z = 4. The main building block is an {ScP2O11}9– unit, forming layers parallel to (001). These layers are stacked along [001] via common corners…
Summary In the discrete element method (DEM) simulation for wear prediction, structural boundary is now represented extensively by triangular meshes with high resolution, which brings a huge computational cost. A DEM‐based method for predicting the wear evolution of structural boundary has been developed for computati…
Abstract InAs 1- x Sb x nanowires show promise for use in nanoelectronics, infrared optoelectronics and topological quantum computation. Such applications require a high degree of growth control over the growth direction, crystal quality and morphology of the nanowires. Here, we report on the silver-assisted growth of…
