Robust fabrication of electroactive multilayer films from a cationic metallocene-containing polymer and their redox-controlled disassembly are presented. Multilayers are assembled from the cationic cobaltocenium polymer (PMCl) and anionic poly(styrene sulfonate) (PSS), and the effect of salt on the assembly process is…
We investigate electromagnetic (EM) scattering and plasmonic cloaking in a system composed of a dielectric cylinder coated with a magneto-optical shell. In the long-wavelength limit we demonstrate that the application of an external magnetic field can not only switch on and off the cloaking mechanism but also mitigate…
A consistent algorithm for extracting the polarisability matrix of bianisotropic meta‐atoms directly from their reflection and transmission properties is introduced in this study. Considering a two‐dimensional periodic distribution of the scatterer under study, illuminated by properly‐polarised, normally‐incident, pla…
The use of severe plastic deformation techniques for processing magnesium alloys has moved from the early difficulties of processing to a stage of tailoring the best properties of these materials. The present paper reviews processing, structure and mechanical properties characterization. It is shown that ultrafine-gra…
Acrylonitrile–styrene–acrylic (ASA) terpolymer was blended with a sodium neutralized poly (ethylene‐co‐methacrylic acid) ionomer to develop a weather‐resistant ASA with good heat sealing and adhesion properties. Both tensile strengths and modulus were reduced by about 45% with an increase in Na‐ionomer concentration o…
Bi2Te3 thin films were deposited by atomic layer deposition (ALD) from BiCl3 and (Et3Si)2Te at 160-300 °C. The process was studied in detail, and growth properties typical of ALD were verified. Films were stoichiometric with low impurity content. The film thickness was easily controlled with the number of deposition c…
This study investigated the use of ethylene vinyl acetate (EVA) matrix in controlled release packaging. Mangiferin, having high antioxidant activity, was incorporated into the EVA matrix with different vinyl acetate (VA) contents. Mangiferin release rate increased with increasing VA content (or decreasing crystallinit…
Photo-induced charge transfer at the interface of two materials is a fundamental process in photovoltaic applications. In this study, we have considered a model of a simplified photovoltaic cell composed of a Si nanocrystal co-doped with Al and P, interfacing with Au electrodes. The photo-induced time-dependent electr…
ABSTRACT The PLA/OMMT nanocomposites were produced using a melt compounding technique with isopropylated triaryl phosphate ester flame retardant (FR; 10–30 parts per 100 resin). The flammability of the PLA/OMMT composites was evaluated with an Underwriter Laboratory (UL‐94) vertical burning test, and their char morpho…
Assembly techniques of graphene have attracted intense attention since their performance strongly depends on the manners in which graphene nanosheets are arranged. In this work, we demonstrate a viable process to synthesize winged graphene nanofibers (G-NFs) which could generate optimized pore size distribution by the…
Polymer coated gold nanoparticle-protein agglomerates having excellent protease and human blood serum stability are reported. These biocompatible agglomerates served as nanocarriers (NCs) for the hydrophobic anticancer drug camptothecin. The NCs were fabricated based on non-covalent interactions and meet the size crit…
A nonadiabatic excited state dynamics study of ⟨001⟩ anatase TiO2 nanowire is obtained by combining density matrix in Liouville-Redfield formalism and ab initio electronic structure calculations. The properties of eigenvectors of Liouville-Redfield superoperator are investigated. The time evolutions of Kohn-Sham orbit…
Amyloid fibrils are formed by a model surfactant-like peptide (Ala)10-(His)6 containing a hexa-histidine tag. This peptide undergoes a remarkable two-step self-assembly process with two distinct critical aggregation concentrations (cac's), probed by fluorescence techniques. A micromolar range cac is ascribed to the fo…
To prepare a functional fiber surface with alterable superhydrophobic–superhydrophilic wettability on fabrics, a TiO 2 hybrid sol was synthesized with tetrabutyl titanate and a fluoride silane coupling agent, 1H,1H,2H,2H-perfluorooctyltrimethoxysilane, via sol–gel technology. Within irradiation under UV light, the dec…
High-pressure powder X-ray diffraction and Raman scattering measurements in cubic bixbyite-type indium oxide (c-In 2 O 3 ) have been performed at room temperature. On increasing pressure c-In 2 O 3 undergoes a transition to the Rh 2 O 3 –II structure but on decreasing pressure Rh 2 O 3 –II-type In 2 O 3 undergoes a tr…
The recent extension of Rosenfeld's fundamental measure theory to anisotropic hard particles predicts nematic order of rod-like particles. Our analytic study of different aligned shapes provides new insights into the structure of this density functional, which is basically founded on experience with hard spheres. We c…
Gold supercrystals with polyhedral morphologies can be prepared from the ordered packing of octahedral and rhombic dodecahedral nanocrystals in the presence of a sufficient amount of surfactant by slow water droplet evaporation. The whole supercrystal formation process has been video-recorded using a specially designe…
In this research, a new polymorph of florfenicol (form B) was discovered and successfully prepared. The new polymorph was characterized and identified by powder X-ray diffraction (PXRD) and differential scanning calorimetry (DSC) techniques. It was found that form A has lower melting temperature while higher fusion en…
We have investigated the reaction of ultrathin Al 2 O 3 /NiAl(110) films with water vapor from ultrahigh vacuum to relative humidities (RH) up to 10%, over the temperature range from −5 to 65 °C, using ambient pressure X-ray photoelectron spectroscopy (APXPS) and scanning tunneling microscopy (STM). The APXPS experime…
A CoSiBEA zeolite was obtained by a postsynthesis method which consisted of a treatment of tetraethylammonium BEA zeolite with nitric acid in the first step and introduction of Co ions into the vacant T atom sites of the SiBEA zeolite by reaction of aqueous Co(NO 3 ) 2 solution with silanol groups. The introduction of…
