Increasing the throughput of the powerful single-step glancing angle deposition (GLAD) method using a prototype simplified roll-to-roll (R2R) system has been explored. While the conventional GLAD technique is popular for fabricating nanostructured devices in a single deposition step, it is not a high-output process. T…
In order to explore possible ways of using metallocene compounds in heterogeneous catalysis and in sensor applications, we present a theoretical characterization of cyclopentadienyl (Cp) + transition metal (TM) complexes adsorbed on boron-doped carbon nanotubes (B-CNTs) and boron-doped graphenes. Using spin-polarized…
A detailed optical study for a Schiff's base liquid crystalline nO.m compound (6O.6) is reported in this article. The phase transition temperatures for the compound were investigated using a polarising microscopy and differential scanning calorimetry (DSC). Refractive index studies were conducted using the thin prism…
With a first principles method, we have investigated the rhombohedral distortion effects on the electronic structure of LaCoO3. Fixed spin moment calculations show two local minima—a non-magnetic and a ∼1.3μB magnetic state. The energy difference between these states is sensitive to the rhombohedral distortion. The Ge…
Das hässliche Entlein wird zum Schwan: Viele Organismen bilden ihre kristalline Mineralphase durch Sekundärnukleation sphärischer amorpher Nanoteilchen. Stabile amorphe Calciumcarbonat-Biomineralien wurden verwendet, um eine ähnliche Umwandlung in vitro auszulösen. Die amorphen Nanosphären gingen eine Festphasenumwand…
Organic–inorganic nanocomposite coatings were prepared from tetraethylorthosilicate and 3-glycidoxypropyltrimethoxysilane (GPTMS) by sol–gel method. These ormosil films were deposited by dip coating on aluminium alloy 5083. The effect of the concentration of GPTMS on the adhesion, mechanical and corrosion performance…
A simple evaporation method was applied to deposit films of hydrophobic organic compounds, either polyethylene (PE) or 1 H,1 H,2 H,2 H-perfluorodecyltriethoxysilane (PFDS), on various steel surfaces. The endurance of these films was evaluated after ultrasonic cleaning, ultraviolet (UV) light irradiation and heat treat…
PURPOSE: This paper reports a technique that enables the quantitative determination of the concentration of gold nanoparticles (GNPs) through the accurate detection of their fluorescence radiation in the diagnostic x-ray spectrum. METHODS: Experimentally, x-ray fluorescence spectra of 1.9 and 15 nm GNP solutions are m…
Superparamagnetic iron oxide nanoparticles (SPIONs) (about 15 nm) were synthesized via a hydrothermal method and characterized by field emission scanning electron microscopy, transmission electron microscopy, dynamic light scattering, x-ray diffraction, and vibrating sample magnetometer. The molecular pathways of SPIO…
This work presents a mathematical approach to make the most efficient use of historical data from development experiments (or commercial manufacture) to select the ingredients for the composition of a new product or to select the materials from inventory for the manufacture of a new lot of finished product. The method…
We report the magnetic behavior, relaxometry, phantom magnetic resonance imaging (MRI), and near-infrared (NIR) photoluminescence spectroscopy of gadolinium (Gd) catalyzed single-walled carbon nanotubes (Gd-SWCNTs). Gd-SWCNTs are paramagnetic with an effective magnetic moment of 7.29 μB. Gd-SWCNT solutions show high r…
Effects of alumina-leached coal fly ash residue (ACFAR) on magnesium oxychloride (MOC) cement are comprehensively investigated. The results show that the addition of ACFAR delayed the setting time of MOC paste. The compressive strength, the flexural strength and the water resistance of MOC are improved by the incorpor…
Controlled self-assembly of gold nanorods (AuNRs) into nanostructures of various morphologies has attracted considerable interest because it provides a high degree of freedom in tailoring the properties of the nanostructures by the coupling of the optical and electronic properties of the individual AuNRs. This paper p…
Quantitative correlation between critical air velocity and roughness of microstructured surface has still not been established systematically until the present; the dynamics of water droplet detachment by air flow from micropillar-like superhydrophobic surfaces is investigated by combining experiments and simulation c…
Blends of polyvinyl alcohol (PVA) and angico gum (AG) and/or cashew gum (CG) were used to produce films by casting method. Morphological and mechanical properties of these films were studied and compared to the properties of a commercial collagen membrane of bovine origin (MBO). The films presented thickness varying f…
We report the synthesis of colloidal CdSe/Cu(3)P/CdSe nanocrystal heterostructures grown from hexagonal Cu(3)P platelets as templates. One type of heterostructure was a sort of "coral", formed by vertical pillars of CdSe grown preferentially on both basal facets of a Cu(3)P platelet and at its edges. Another type of h…
This article is aimed at developing a nonclassical Mindlin rectangular functionally graded material (FGM) microplate based on the strain gradient theory (SGT) to study the thermal buckling behavior of microplates with different boundary conditions. This theory comprises material length scale parameters to interpret si…
Doxorubicin, together with the modified polysaccharide (alginate dialdehyde), was used as a wall material to fabricate microcapsules through self-cross-linking by a template method. The microcapsules as-prepared are pH-responsive. Relevant scanning electronic microscopy, atom force microscopy and confocal laser scanni…
The fabrication of flexible multilayer graphene oxide (GO) membrane and carbon nanotubes (CNTs) using a rare form of high-purity natural graphite, vein graphite, is reported for the first time. Graphite oxide is synthesized using vein graphite following Hummer’s method. By facilitating functionalized graphene sheets i…
Polymer or plastic electronics offers the promise of a new kind of semiconductor industry; one where materials are easily processed and devices are cheap and, in some cases, even flexible. Polymers can be used in transistor circuitry (chips), sensors, RFID tags, electrochromic windows, and optoelectronic devices such…
