Using Monte Carlo simulations the interaction of a nanometre-sized, spherical Janus particle (a particle with two distinct surface regions of different functionality, in this case showing amphiphilic behaviour) with an ideal fluid interface is studied. In common with previous simulations of spherical, isotropic partic…
Epoxidized canola oil may be well suited to the partial replacement of petroleum products in composite matrices; however, a process is needed to obtain this material from canola oil at sufficient conversion and scale to assess product properties. Therefore, canola oil was epoxidized in a solvent-free process with a he…
Poly(3,4‐ethylenedioxythiophene):poly(4‐styrenesulfonate) (PEDOT:PSS) doped with multi‐walled carbon nanotubes (MWCNTs) films is fabricated on quartz substrates by spin coating method. The effects of MWCNTs on the structure and properties of PEDOT:PSS film have been investigated. X‐ray diffractometer (XRD) and Fourier…
Single-crystal, submicrometer-sized CaS:Eu luminescent particles were synthesized via a solvothermal route, and these moisture-sensitive particles were coated with aluminum oxide using atomic layer deposition (ALD). Photoluminescence (PL) spectra of coated and uncoated particles were compared. They both showed a broad…
Microcrystalline cellulose (MCC) is an important ingredient in pharmaceutical, food, cosmetic and other industries. In this work, MCC was prepared from the alpha cellulose content of groundnut husk, a renewable natural resource that has no industrial utilization yet. The effects of pulping methods (sodium hydroxide an…
There have been numerous studies of the electrode materials of electric double-layer capacitors (EDLCs), such as activated carbons, carbon nanotubes, and other carbon-based materials which have a high specific surface area. Of the materials being developed for EDLCs, activated carbon remains the most promising because…
Magnetism and the mechanism of magnetic coupling in graphene decorated with monovalent and divalent adsorbates were investigated using first-principles calculations based on spin polarized density functional theory. The effects of adsorption concentration and the electronegativity of the adsorbate species on the magne…
The in vitro validation of a new pH mapping MRI method based on a supramolecular poly-beta-cyclodextrin-19F-Gd adduct is reported.
Cyclometallated iridium complexes comprised of two terdentate cyclometallating ligands, of the form [Ir(Ninsertion markCinsertion markN)(Ninsertion markNinsertion markC)](+), have been explored for the preparation of multimetallic systems by palladium-catalysed cross-coupling reactions. An Ninsertion markNinsertion ma…
The complexes and contain [M(bipy)(3)](2+) chromophores with a pendant aza-18-crown-6 macrocycle for binding of lanthanide(iii) ions. The photophysical properties of the adducts . and ., prepared by addition of excess Ln(NO(3))(3) (Ln = Nd, Yb) to solutions of and in MeCN, were examined using time-resolved and steady-…
In this paper we report on dye structure–optical property correlations for a range of near-infrared emitting (NIR, 650–900 nm) fluorescent dyes in a 9–14 nm diameter core-shell silica particle architecture (C dots), including Cy5, Alexa Fluor 700, DY730, Alexa Fluor 750, and DY780. For each dye an apparent per-dye enh…
In vitro studies were carried out to test the antifungal activity of 5 plant extracts; Cinnamomum zeylanicum (Cinnamon), Cymbopogon proximus (Halfa barr), Laurus nobilis (Laurel), Persea americana (Avocado) and Zingiber officinale (Ginger) performed with either cold distilled water (CDW) or boiling (BDW) on two pathog…
Angle-resolved photoemission spectroscopy (ARPES) is a powerful experimental technique for directly probing electron dynamics in solids. The energy versus momentum dispersion relations and the associated spectral broadenings measured by ARPES provide a wealth of information on quantum many-body interaction effects. In…
One of the most known intelligent material is nitinol, which offers many functional advantages over conventional implantable alloys. Applications of SMA to the biomedical field have been successful because of their functional qualities, enhancing both the possibility and the execution of less invasive surgeries. The b…
A series of mesostructured H3PW12O40-silica materials were developed by using a single step co-condensation technique in the presence of nonionic oligomeric surfactant, C18H37(OCH2CH2)10OH (C18EO10, Brij76). By tuning the composition ratios of the starting precursors (mainly the molar ratios of water to the other mate…
Ammonia borane (NH(3)BH(3), AB) is an intriguing molecular crystal with an extremely high hydrogen capacity and moderate thermal stability. In the present study, we show a simple but effective approach for destabilizing AB for promoted hydrogen release at moderate temperatures. It is found that mechanically milling wi…
Chemical oxidation of poly(enetetramine)s was demonstrated as a new synthetic route to prepare conjugated polyelectrolytes.
We report on an approach to obtain anodic self-organized TiO 2 nanotube layers with a significantly improved tube morphology. Before the anodic tube growth, a rutile layer is formed on the Ti substrate by high temperature oxidation in air. This layer protects the tube tops during anodization against chemical etching i…
Polymer nanocomposites (PNCs) often exhibit excellent mechanical, thermal, electrical and optical properties, because they combine the performances of both polymers and inorganic or organic nanoparticles. Recently, computer modeling and simulation are playing an important role in exploring the reinforcement mechanism…
Size-controlled atomic-level Pd-Au alloy nanoparticles have been synthesized with a wide range of atomic ratios by a facile method using H2 gas, and their controllable hydrogen-absorption properties have been studied from hydrogen pressure-composition isotherms and solid-state 2H NMR spectra.
