In this article, the nanotubes obtained by silicon atoms substitutionally doping the single-walled carbon nanotubes were investigated by quantum chemistry calculations under the framework of density functional theory. The geometrical structures, relative stabilities and electronic properties of the Si-doped tubes were…
This paper reports on substrate-induced bianisotropy in an impedance-matched near-zero-index metallodielectric fishnet nanostructure with vertical sidewalls and a supporting substrate. The effect of bianisotropy on the metamaterial optical properties is confirmed through spectral holography measurements and full-wave…
This paper reports a theoretical analysis of the electronic structure and magnetic properties of a ferromagnetic Cu(II) [2 × 2] grid. The calculations confirm a quintet (S = 2) ground state and an energy-level distribution of the magnetic states in accordance with Heisenberg behaviour. The whole set of first- and seco…
The one-pot chemical functionalization of short carboxyl multi-walled carbon nanotubes (Sh-MWCNT-COOH) with ninhydrin and thiourea for producing 3a,8a-dihydroxy-2-thioxo-1,3,3a,8a-tetrahydroindeno[1,2-d]imidazol-8(2H)-one (Sh-MWCNT-inden) via thermal and microwave methods have been investigated. The product was charac…
The currently increasing awareness of an alarming lack of specific knowledge on developmental nanotoxicity significantly adds to the anyway growing anxiety about possible adverse health effects of ...
Thermoplastic polyurethanes (TPUs) are widely used in biomedical applications because of their excellent mechanical properties and biocompatibility. However, their role as possible matrices for drug delivery has received little attention. In this study, the loading and release of model drugs from different TPUs using…
Abstract Owing to their applications in biodetection and molecular bioimaging, near‐infrared (NIR) fluorescent dyes are being extensively investigated. Most of the existing NIR dyes exhibit poor quantum yield, which hinders their translation to preclinical and clinical settings. Plasmonic nanostructures are known to a…
Strongly enhanced and spatially confined near-fields in the vicinity of plasmonic nanostructures open up exciting new capabilities for photon-driven processes and particularly also for optical spectroscopy. Surface enhanced Raman signatures of single molecules can provide us with important information about the optica…
We investigated the device characteristics of a graphene field effect transistor (FET) of which interfaces were controlled by a self-assembled monolayer (SAM). Electrical transport measurements together with Raman spectroscopy characterizations for bilayer graphene (BLG) and single layer graphene (SLG) on micro-patter…
Hydrogen gas, which can be used in fuel cells to generate electricity, is considered the ultimate clean energy source. Recently, it was reported that a photo-induced electron transfer system consisting of single-walled carbon nanotubes (SWCNTs) and fullerodendrons shows photo-catalytic activity with a very high quantu…
Biaxial melt‐drawing produces a high‐performance poly(tetrafluoroethylene) (PTFE) membrane with excellent mechanical properties and superior transparency. Unique two‐step molding gives the better adhesion between the PTFE powder materials even with ultra‐high molecular weight of 10 7 . Such void‐free film can be succe…
(Perfluorodecyl)decane, F(CF2)10 (CH2)10H, was studied using optical microscopy, differential scanning calorimetry and X-ray diffraction. A smectic B liquid crystalline phase, due to the amphiphili...
The corrosion inhibition efficiency of a potential polynuclear Schiff base, (s)-2-(anthracene-9 (10H)-ylidene amino)-5-guanidinopentanoic acid (A9Y5GPA), on carbon steel (CS) in 1 M hydrochloric acid solution has been investigated using weight loss measurements, electrochemical impedance spectroscopy (EIS), and potent…
X-ray microanalysis conducted using the scanning electron microscope is a technique that allows the determination of chemical elements in bulk or semi-thick specimens. The lowest concentration of an element that can be detected is in the order of a few mmol/kg or a few hundred parts per million, and the smallest amoun…
Electric field activated nonlinear transport is investigated in polypyrrole thin film in both in-plane and out-of-plane geometries down to 5 K and strong anisotropy is observed. A morphological model is suggested to explain the anisotropy through inter-chain and intra-chain transport. The deviation from the variable r…
We evaluated electronic structures and magnetic moments in Co3FeN epitaxial films on SrTiO3(001). The experimentally obtained hard x-ray photoemission spectra of the Co3FeN film have a good agreement with those calculated. Site averaged spin magnetic moments deduced by x-ray magnetic circular dichroism were 1.52 μB pe…
Rhodium supported on lanthanoid (La, Ce, Pr, or Nd)-containing ZrO2 was investigated as a three-way catalyst following an aging treatment (oxidation at 1273 K) that simulates 80 000 km of mileage in real vehicles. The properties of rhodium were assessed by transmission electron microscopy, CO chemisorption, and temper…
Abstract We have demonstrated that oligo(phenylisoxazolyl)benzenes 3–6 formed polymeric assemblies. The intermolecular associations were discussed using thermodynamic parameters. The formation of the polymeric assemblies were confirmed by DOSY and AFM measurements. The large polymeric structures were observed both in…
In this work, a hybrid‐polymer nanocomposite film, based on polyvinyl butyral/amino‐silane functionalized nano alumina, was fabricated by melt processing. The calcium degradation measurements suggest the functionalized nanocomposite films exhibit higher resistance towards moisture penetration as compared to the neat a…
N-type doping of graphene with long-term chemical stability in air represents a significant challenge for practical application of graphene electronics. This paper reports a reversible doping method to achieve highly stable n-type graphene nanomeshes, in which the SU-8 photoresist simultaneously serves as an effective…
