The interaction mechanism of threonine (Thr) on the sidewall of (8, 8) single-walled carbon nanotubes (CNTs) was investigated by density functional tight-binding method. All the functional groups of Thr were used to interact with the surface of CNT. The structural parameters were analyzed to identify the noncovalent i…
Molecular dynamics (MD) simulations are performed to study the correlation between electron irradiation defects and applied stress in graphene. The electron irradiation effect is introduced by the binary collision model in the MD simulation. By applying a tensile stress to graphene, the number of adatom-vacancy (AV) a…
Transparent conductive thin films are a key building block of modern optoelectronic devices. A promising alternative to expensive indium containing oxides is aluminum doped zinc oxide (AZO). By correlating spectroscopic ellipsometry and photoluminescence, we analyzed the contributions of different optical transitions…
Purpose – The purpose of this paper was to investigate the effects of SO 4 2− concentration on the corrosion behaviour of T23 and T12 steels in simulated water chemistry condition solution of 600 MW fossil-fired power boilers. Design/methodology/approach – The influence and mechanism of SO 4 2− ions on the pitting cor…
A variety of H– and Na–saponite supports have been prepared by several synthesis approaches; the best activity for soot combustion was achieved with copper oxide supported on a Na–saponite prepared at pH 13 and with surfactant.
We present the results of exploratory research on the fast synthesis of few-layered graphite via a self-propagating high-temperature synthesis (SHS). We reported previously that different solid carbonates and gaseous carbon oxides could be directly converted into novel nanocarbons using strong reducers and SHS approac…
We report a magnetic force microscopy study of the magnetic domain evolution in the layered manganite ${\mathrm{La}}_{2\ensuremath{-}2x}{\mathrm{Sr}}_{1+2x}{\mathrm{Mn}}_{2}{\mathrm{O}}_{7}$ (with $x=0.32$). This strongly correlated electron compound is known to exhibit a wide range of magnetic phases, including a rec…
Gapped hollow BaTiO3 nanospheres with an apparent diameter of 93 ± 19 nm (shell thickness of 10-20 nm) were synthesized via a dynamic hydrothermal process using TiO2 sols and Ba(2+) ions as the Ti and Ba sources in alkaline aqueous solutions. The phases and morphologies of the BaTiO3 samples were characterized by X-ra…
Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans the biological, physical, and social sciences.
Combinations of complex metal borohydrides ball milled with the transition metal complex hydride, Mg2FeH6, are analysed and compared. Initially, the Reactive Hydride Composite (RHC) of Mg2+ cation mixtures of Mg2FeH6 and γ-Mg(BH4)2 is combined in a range of molar ratios and heated to a maximum of 450 °C. For the molar…
Marine and inland pollution by non-degradable plastic bags and other plastic articles is a topic of great concern. Natural degradation processes based on oxidation of plastic pollutants could possibly contribute to limit the extent of pollution. Thermal degradation of polyolefins in the absence of light by non-polluti…
Extrinsic contributions play an important role in the functionalities of ferroelectric materials, while domain structure evolution is crucial for understanding the extrinsic dielectric and piezoelectric responses. In this work, domain configuration changes with an electric field applied along [001]C in the tetragonal…
Er(3+) activated germanate glasses modified by La2O3 and Y2O3 with good thermal stability were prepared. 2.7 μm fluorescence was observed and corresponding radiative properties were investigated. A detailed discussion of J-O parameters has been carried out based on absorption spectra and Judd-Ofelt theory. The peak em…
Two-dimensional hexagonal arrays of Pt nanoparticles (1.5 nm diameter) have been obtained by deposition of preformed and size selected Pt nanoparticles on graphene. This original self-organization is induced, at room temperature, by the 2D periodic undulation (the moiré pattern) of graphene epitaxially grown on the Ir…
The mechanical properties and bio-corrosion behaviours of T4 solid solution heat-treated Mg–1.5Zn and Mg–9Zn alloys at 340°C under different heat treatment durations were investigated. In vitro corrosion behaviour of the heat-treated alloys immersed in simulated body fluid (SBF) were measured by electrochemical, hydro…
We report a fluorescence resonance energy transfer (FRET) system in which the fluorescent donor is fluorescein isothiocyanate (FITC) dye and the fluorescent acceptor is CdTe quantum dot (QDs). Based on FRET quenching theory, we designed a method to detect the concentration of silver ions (Ag(+)). The results revealed…
The vascular endothelial cells (EC) extracellular matrix (ECM) on the biomaterial surface can significantly improve the blood compatibility and cell compatibility of the cardiovascular materials. In the present study, two types of micropatterned TiO2 nanotubes surfaces (gronano and toponano) were fabricated on the tit…
Abstract The sulfide fusion method was used to synthesize Gd 2 O 2 S:Tb phosphors using commercial Gd 2 O 3 and freshly prepared Gd 2 O 3 , respectively. The freshly prepared Gd 2 O 3 was synthesized from Gd 2 O(CO 3 ) 2 ·H 2 O precursor prepared by homogeneous precipitation method. The structure and morphology of the…
The structure of graphene obtained by chemical exfoliation of graphite via the oxidation/reduction procedure has been determined using wide-angle scattering of neutrons and X-rays combined with computer simulations based on classical molecular dynamics (MD). A comparison of results obtained from wide-angle neutron sca…
A promising approach in designing composite materials with an unusual physical behavior combines solid nanostructures and orientationally ordered soft matter at the mesoscale. Such composites can not only inherit properties of their constituents but also can exhibit emergent behavior such as ferromagnetic ordering of…
