In this article, a semi-analytical finite element approach based on the nonlocal elastic shell model is proposed to study the thermal buckling of multiwalled carbon nanotubes (MWCNTs). By taking nonlocality into consideration, the small scale effect is incorporated into the model presented herein. Based upon the Ering…
Despite the great potential of the application of surface-enhanced Raman scattering (SERS), the difficulty in fabricating suitable SERS substrates is still a challenge. Based on the self-assembly of silica nanoparticles, the image shows a highly ordered, 3D petallike arrayed structure that serves as a promising SERS s…
Abstract Reinforcement of interfacial adhesion between syndiotactic polypropylene (SPP) and fibrous pure cellulose (FC) was performed by the FC silanizations with 3‐aminopropyltrimethoxysilane (APTMS), with hexyltrimethoxysilane (HTMS) and by an addition of a SPP grafted with dimethyl itaconate (SPP‐g‐DMI: number‐aver…
The electrochemical behavior of cysteine and cystine on carbon-paste electrodes modified with Fe(II), Co(II), Ni(II), and Cu(II) phthalocyanines is studied. Metal phthalocyanines exhibit catalytic activity in the electrooxidation of cysteine and cystine and in the reduction of cystine. The best catalyst is the cobalt…
Electronic phases with stripe patterns have been intensively investigated for their vital roles in unique properties of correlated electronic materials. How these real-space patterns affect the conductivity and other properties of materials (which are usually described in momentum space) is one of the major challenges…
Reduktion ohne Partikelwachstum: Ti2O3-Nanopartikel mit Korundstruktur wurden durch Reduktion von TiO2-Nanopartikeln vom Rutiltyp mit CaH2-Pulver bei einer niedrigen Temperatur von 350 °C hergestellt. Die Morphologie des reduzierten Oxids ist die gleiche wie die der Vorstufe, obwohl die Kristallstruktur vom tetragonal…
Sintering of green samples of alumina produced by ice-templating was followed in situ in an environmental scanning electron microscope (ESEM) up to temperatures as high as 1375°C. These alumina samples with well-defined architectures are of great interest in the field of materials science due to their high specific st…
In this article, the reactivity of Ti 2 AlC powders, with 3 and 10 μm alumina, Al 2 O 3 , fibers during pressure‐assisted sintering is explored. Samples were fabricated by hot‐isostatic‐pressing ( HIP ed) or hot‐pressing ( HP ed), and characterized by X‐ray diffraction, differential thermal analysis, and electron micr…
Magnesium hydroxide was obtained in a precipitation reaction with the use of magnesium nitrate or magnesium sulphate and sodium hydroxide. The influence of the temperature of the process, the mode and rate of substrate supply, as well as the concentration and ratio of the substrates on the product's properties, were t…
Abstract Maleic anhydride copolymer was modified with another biologically active agent, noradrenaline (NA), using both chemical and enzymatic methods. The modification and synthesized products were named as follows: chemical modification, MASTNAc; enzymatic modification, MASTNAe; enzymatically synthesized MASTNA from…
The ceramic multilayer technique, which is based on tape‐cast green sheets, has the potential to generate advanced composite materials. In this work, high‐purity refractory oxides like α‐alumina, magnesia, and magnesium aluminate spinel were used for tape casting and multilayer processing. Highly porous Al 2 O 3 and M…
Abstract Postconsumer poly(ethylene terephthalate) waste bottles were glycolyzed as precursors of unsaturated polyester resin (UPR) and their montmorillonite (MMT)‐filled nanocomposites. The glycolysis product (hydroxyl‐terminated oligomers) was converted into UPR with various acid contents. These resins were miscible…
Abstract The UV irradiation aging behaviors of PVC composites with several inorganic fillers were studied through Fourier transform spectroscopy (FTIR), ultraviolet spectroscopy (UV‐Vis), differential scanning calorimeter (DSC), scanning electron microscopy (SEM), and mechanical property test. It was found that incorp…
Using the transfer-matrix method, we study the conductance of chiral particles through a monolayer graphene superlattice with long-range correlated disorder distributed on the potential of the barriers. Even though the transmission of the particles through a graphene superlattice with white-noise potentials is suppres…
Polyaniline (PANI) and humic acid (HA) composite sorbents were prepared by adding different amount of HA into the chemical oxidation process of PANI. The sorbents were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, and N2 adsorption and desorption. Batch adsorptio…
Abstract This article deals with the feasibility of using recycled corrugated paper board (rPF) as the reinforcing material for recycled plastics. The composites of recycled polypropylene (rPP) and rPF were prepared by extrusion compounding and injection molding, and the rPP/rPF composites compatibilized by maleic anh…
We report on studies of the tailored self-assembly of the perylene diimide derivative, N,N'-ditridecylperylene-3,4,9,10-tetracarboxylic diimide, into structures with fibrous gel-type, one-dimensional, and two-dimensional morphologies. This approach for producing highly ordered nanostructures of well-defined morphologi…
Reversible topographical changes were observed on a photochromic diarylethene microcrystalline film surface by alternate irradiation with UV and visible light. Two types of surfaces were prepared from this film: 1) Storage of the film at 30 °C for 24 hours in the dark after UV irradiation afforded a surface that was c…
Superconductivity in doped BaFe2As2 is controlled by the charge of the (FeAs)δ− layers. Adjustment from electron to hole doping in Ba1−xKxFe1.86Co0.14As2 tailors the system from superconductivity to static magnetic order and back to superconductivity. When the charges compensate each other, the magnetic phase similar…
Abstract Photoluminescence from ZnO based films deposited by screen printing is studied. PL spectra of undoped films show strong broad green emission around 500 nm and a weak (nearly one fourth of visible) UV emission around 398 nm. Further enhancement of 30% in the green emission is observed as 5 at.% Ca is doped in…
