High Resolution Image Download MS PowerPoint Slide In this work, copper selenide (Cu 3 Se 2 umangite phase) was synthesized by two routes, using a chemical reaction and the hydrothermal method to obtain CuSe-A and CuSe-H, respectively. The synthesis of Cu 3 Se 2 consisted of a three-step process: in the first step, co…
Inspired by the morphology of Coscinodiscus species diatom, bi-layered photonic structures comprised of dielectric-filled nano-holes of varying diameters have been designed and analyzed to enhance and tune absorption characteristics of GaAs-based thin-film photonic devices. Finite difference time domain-based numerica…
Abstract A new strategy to chemically synthesize exchange‐coupled SmCo 5 /Sm 2 Co 17 nanocomposites by in situ decomposition of SmCo x (5 < x < 8.5) is reported in this work. Our synthesis starts with the fabrication of Co/Sm 2 O 3 (Sm to Co atomic ratio of Sm/Co = 1:4.2), which can be reduced into 40‐nm SmCo 5 single…
CuAlCe oxides were obtained from hydrotalcite-type precursors by coprecipitation using a M2+/M3+ ratio of 3. The collapse of the layered double hydroxide structure following the thermal treatment leads to the formation of mixed oxides (CuO and CeO2). The catalytic performance of the copper-based catalysts was evaluate…
Nanoparticles of zinc oxide were synthesized by a solution combustion method. The average size of these particles was analyzed by using X-ray diffraction. Composites of natural rubber and the ZnO nanoparticles were prepared by a latex blending method. The matrix phase was cured by using the crosslinking agent, pentane…
Safe and efficient use of ultrasmall nanoparticles (NPs) in biomedicine requires numerous independent conditions to be met, including colloidal stability, selectivity for proteins and membranes, binding specificity, and low affinity for plasma proteins. The ability of a NP to satisfy one or more of these requirements…
Two-dimensional van der Waals magnets with multiple functionalities are becoming increasingly important for emerging technologies in spintronics and valleytronics. Application of external pressure is one method to cleanly explore the underlying physical mechanisms of the intrinsic magnetism. In this paper, the magneti…
Abstract Molecular dynamics (MD) simulations were used to study the effects of gravity, solid surface energy, and the fraction of water–solid interface area on the water droplet sliding angles on nanopillared surfaces. To effectively simulate the influence of gravity on drop sliding, we developed a protocol in which w…
Diluted magnetic semiconductors (DMSs) have drawn much attention due to their potential in spintronics and magnetoelectronics. Transparent conducting oxides, which are characterized by high carrier density and mobility, may provide a platform to realize room-temperature DMS oxides via the carrier-induced ferromagnetis…
Multiferroics that simultaneously exhibit ferroelectricity and ferromagnetism have recently attracted great attention due to their potential application in next generation electronic devices. However, only a few single-phase multiferroic materials exhibit ferroelectric and ferromagnetic orders at room temperature. Rec…
Abstract Carbonized polymer dots (CPDs) have been widely applied in biomedical fields, such as imaging, diagnosis and drug delivery. Since the complex, non‐equilibrated and dynamic nature of biological systems inevitably affect the predesigned properties of CPDs, then efficiency and ultimate outcome of CPDs in biologi…
This paper presents results of the experimental studies on immobilization of radioactive waste in composite elastomeric matrices based on the natural rubber and mineral fillers lignite slag and bismuth oxide. For preparation of the matrices a classical mixing procedure using a roll mill was applied using isotopically…
The utilization of structural water in chemical self-assembly has not only effectively eliminated the negative influences of solvents from solutions or gels but has also provided new insight into the fabrication of new materials in bulk. However, up to now, supramolecular polymerization triggered by structural water h…
Acid-soluble collagens from European hake and Blue shark skin were isolated, characterized, and compared. As the structure of collagen determines its function, the final objective of this study was to investigate biochemical differences between both collagens to identify future potential applications. Chromatographic…
Intrinsically fluorescent biocompatible multifunctional multipurpose terpolymers, i.e., methyl methacrylate- co -methyl 3-( N -isopropylacrylamido)-2-methylpropanoate- co - N -isopropylacrylamide (MMA- co -MNIPAMP- co -NIPAm, 1 ) and methyl methacrylate- co -methyl 3-( N -hydroxymethylacrylamido)-2-methylpropanoate- c…
Employing a peptide-based nanoscale drug delivery system is an effective strategy to overcome the poor therapeutic outcomes of chemotherapeutic drugs. Here, we developed a self-assembling peptide-drug delivery system comprising a self-assembling anticancer peptide (R-lycosin-I), as revealed in our previous study, and…
Recent years have seen a tremendous rise of two-dimensional (2D) magnetic materials, several of which were verified experimentally. However, most of the theoretical predictions to date rely on ab initio methods, at zero temperature and fluctuation-free, while one certainly expects detrimental quantum fluctuations at f…
Abstract Ce 3+ ion doped BiPO 4 phosphors were synthesized by co‐precipitation method using ethylene glycol as capping agent. The prepared phosphors were characterized by XRD, SEM, FT‐IR, UV‐Vis, and PL spectroscopy techniques. The formation of monoclinic phase was confirmed from XRD and FT‐IR studies. SEM study revea…
Abstract Dithiolanes are used to obtain dynamic and reversible crosslinks between polymer chains. Copolymers of two different dithiolane-containing cyclic carbonate monomers and ?-caprolactone (CL) were synthesized by ring-opening polymerization using a methoxy-poly(ethylene glycol) (mPEG) initiator and different cata…
An approach to optical transduction and amplification of amphiphile-triggered orientational responses of liquid crystals (LCs) based on the interference effect was developed. The sensitive substrate was obtained by lading 4′-pentyl-4-cyanobiphenyl (5CB) into three-dimensionally ordered silica colloidal crystal (SCC) f…
