The surface of an AB5 alloy (LaMmNi4.1Al0.3Mn0.4Co0.45) was modified with Pd nanoparticles using a microwave-assisted polyol method. Cyclic voltammetry (CV) and chronoamperometry (CA) were used to characterize the electrochemical behavior of the resulting composite in 6 M KOH electrolyte. The microwave-assisted polyol…
A shape memory alloy (SMA) is an alloy which can eliminate deformation at lower temperatures and restore its original shape upon heating. SMAs have been receiving considerable attention in the research field of materials science, and their applications include robotics, automotive, aerospace, and biomedical industries…
In this research, the thermal treatment technique has been employed to produce Mn0.5Zn0.5Fe2O4 nanoparticles. Manganese, Zinc and iron nitrates have been mixed with capping agent of polyvinylpyrrolidone. Several techniques have been used to examine the structural, morphological and optical properties of the prepared p…
Longitudinal tracking of living cells is crucial to understanding the mechanism of action and toxicity of cell-based therapeutics. To quantify the presence of administered cells in the host tissue without sacrifice of animals, labeling of the target cells with a nontoxic and stable contrast agent is a prerequisite. Ho…
Abstract In the present work, we developed three new high temperature resistant heavy concretes as novel radiation shielding materials. For this purpose, chrome ore (FeCr2O4), hematite (Fe2O3), titanium oxide (TiO2), aluminum oxide (Al2O3), limonite [FeO (OH) nH2O], siderite (FeCO3), barite (BaSO4), nickel oxide (NiO)…
The abuse of amphetamine-type stimulants (ATS) has increased rapidly and so development of an easy, cheap and sensitive ATS sensor is of great importance. A facile label-free impedimetric sensor was fabricated using cucurbit[7]uril (CB[7]) as a recognition molecule to bind ATS. The presence of CB[7] enables the format…
The study of oil sorbents with high oil sorption capacity is of great significance for oil–water separation, especially for oil spillage on seawater. In this work, we report polysulfone, poly(lactic acid), and polysulfone/poly(lactic acid) nanoporous fibrous mats prepared by one-step electrospinning process used as oi…
Further development of our differential scanning calorimetry (DSC) method for the analysis of solid-solid phase transformations now also allows for its application in the kinetic analysis of age hardening in Mg alloys. As a result, the state-of-the-art for DSC on Mg alloys has been improved with respect to the accessi…
Abstract This study aimed to prepare an inhibitory edible coating for Gouda cheese based on whey protein containing lactoperoxidase system (LPOS) and Bunium persicum essential oil (EO) in order to control postpasteurization contamination. Using a full factorial design, the effects of LPOS and EO on microbiological cha…
Abstract Multifunctional metasurfaces have attracted drastically growing interest, serving as a prominent candidate to cope with both device miniaturization and integration. Conventional transmissive bifunctional metasurfaces working for visible light inherently suffer from several demerits owing to the use of geometr…
Abstract Nonlinear responses in metasurfaces have shown great promise for various applications, such as nonlinear holography, spectroscopy, and novel nonlinear light sources. Metasurfaces that produce nonlinear responses have the advantage of greatly relaxed phase‐matching conditions, which can simplify nonlinear opti…
The agglomeration problem of nanofillers, for instance, carbon nanotubes (CNTs) in a poly(ether ether ketone) (PEEK) matrix, is still a challenging assignment due to the intrinsic inert nature of PEEK to organic solvents. In this work, organically modified montmorillonite (MMT) was introduced as a second filler for im…
Abstract The synthesis of the multi‐component transition‐metal diboride (MeB 2 ) solid‐solution powders has been recently attracting considerable attentions. However, the synthesis of the ternary or more component MeB 2 solid‐solution powders has rarely been reported until now. To fabricate the ternary MeB 2 solid‐sol…
The aim of this research was to evaluate the influence of the curauá or polypropylene fibers on rheological properties of fresh cementitious paste. The variables were the percentage of fiber content 1 wt% or 2 wt% and the length of the curauá or polypropylene fibers: 6 or 10 mm, but it was also prepared paste without…
Abstract Heterostructures of strongly correlated oxides demonstrate various intriguing and potentially useful interfacial phenomena. LaMnO 3 /SrMnO 3 superlattices are presented showcasing a new high‐temperature ferromagnetic phase with Curie temperature, T C ≈360 K, caused by electron transfer from the surface of the…
Abstract PbS nanocrystals have been proven to be highly suitable for photodetector fabrication by facile solution processing, and have been successfully tested as photosensitive material in imaging devices. So far, their spectral response has been blue‐shifted with respect to that of commercial bulk PbS detectors, due…
The demand for multifunctional requirements in aerospace, military, automobile, sports, and energy applications has encouraged the investigation of new composite materials. This study focuses on the development of multiwall carbon nanotube (MWCNT) filled polypropylene composites and carbon nanofiber composite mats. Th…
In order to compensate for the shrinkage of geopolymer pastes uniformly, reactive MgO powders are evenly dispersed in the geopolymer. The deformation performance, mechanical properties, microstructure and components of geopolymer pastes with reactive MgO are characterized. The effects of the content and the activity o…
