We studied the site preference of methanol (CH 3 OH) and methoxy (CH 3 O) on Pt, PtRu and PtRuMo surfaces using density functional theory. This work aimed to investigate the nature of methanol and methoxy adsorption in relation to energetic properties and charge transfers and to clarify the role of alloying metal Ru a…
OLEDs have attractedconsiderable attention for their promising applications inhigh-efficiency, low-drive-voltage, large-area, full-color thinflat-panel displays and white lighting devices. To displayfull-color, blue-, green-, and red-light-emitting materials arerequired, and one of the major challenges for OLEDresearc…
Polaron pair dynamics in regioregular Poly (3-hexylthiophene) (RR-P3HT) film was studied by applying both femtosecond transient absorption and fluorescence up-conversion techniques. The comparison of the dynamics of the pure fluorescence, the ground state bleaching recovery and the polaron pair absorption reveals that…
Photoactivated probes have gained interest as experimental tools to study intracellular signalling pathways all the way to the molecular level. However technical limitations of the means to activate such compounds have put constraints on their use in spatially highly restricted subcellular areas. The Mosaic digital il…
We propose a new approach for converting light energy into electrical energy, based on the photogeneration of nano-dipoles at donor-acceptor interfaces. The nano-dipoles are oriented in space so as to contribute to a collective polarization that induces a potential difference across the material, sandwiched between el…
The self-adaptation of manganese-chloride arrangement with the tripodal ligand 1,3,5-tris(benzimidazoyl-1-ylmethyl)-2,4,6-trimethylbenzene (Me(3)-TBzIm) afforded a rare 3D metal-organic framework, [Mn(5)Cl(10)(Me(3)-TBzIm)(4)](n) (1) showing a high spin ground state with S = 15/2.
The nonlinear dynamics of a nonisothermal thin liquid film on a horizontal cylindrical surface subjected to axial harmonic vibration is investigated in this paper. It is found that the capillary instability of an axisymmetric film on a still cylinder can be saturated via the Marangoni effect by heating the film at the…
Formation of water-in-hexane nanoemulsions has been studied in system water/(Brij 30/Span 80) mixed surfactant/hexane system via a low energy emulsification method: stepwise addition of water to a solution of mixed surfactants in hexane. The influence of surfactant concentration, water content, hydrophilic lipophilic…
A facile route to reassemble titania nanoparticles within the titania-block copolymer composite films has been developed. The titania nanoparticles templated by the amphiphilic block copolymer of poly(styrene)-block-poly (ethylene oxide) (PS-b-PEO) were frozen in the continuous PS matrix. Upon UV exposure, the PS matr…
As an important method of quality confirmation for the ITER Feeder system insulated components, high voltage test at Paschen condition need to be carried out once after these components are manufactured. The Paschen test is much more efficient for detecting the micro cracks or defects in solid multi-composite high pol…
A systematic study to understand the relationship between wavelength uniformity and substrate curvature during InGaN growth is described in relation to the initial bow of sapphire substrate. The initial bow of the substrate acted as the offset parameter for its curvature throughout the stages of the epitaxy process. S…
A quantum chemical investigation of the chemical dry etching of SiO2 using H2 downflow plasma with flowing NF3 was carried out using the B3LYP/6-31+G(d,p) method. The results provide a reasonable interpretation of how the chemical dry etching of SiO2 takes place in a down flow area. Experimentally, it was found that t…
Three open frameworks, [Ni(pnta)2]·1.3DMF (1), [Zn2(pnta)3(OH)]·2DMF (2), and [Cd(pnta)2]·3.8DMF (3), were obtained by solvothermal reactions between 6-(pyridin-4-yl)nicotinic acid (Hpnta) and nickel(II), zinc(II) and cadmium(II) nitrate, respectively. Compound 1 is a chiral framework with a fourfold interpenetrated d…
Ethyl benzoate was found to complex with cyclodextrins in formation of vesicles for the first time. These vesicles were characterized by transmission electron microscopy and dynamic light scattering. The complex stoichiometry, the stability constant and conformations of ethyl benzoate · cyclodextrins in aqueous soluti…
Abstract Poly(acrylic acid) (PAA) was used as an additive to fabricate blended polysulfone (PSF) ultrafiltration (UF) membranes. Hexanediamine was used as a crosslinking agent to react with PAA and formed an active surface with amine group. Then, an end carboxyl group methoxy polyethylene glycol (MPEG) was grafted on…
Impact sensitivity, one of the most important screening factors for novel high energy density materials (HEDMs), was predicted by use of quantitative structure-property relationship (QSPR) based on the electrostatic potential (ESP) values calculated on the van der Waals molecular surface (MSEP). Among various 3D descr…
Coiled Tubings are thin walled steel tubes of 25–89 mm diameter and thousands meters long, used in the oil industry for production and maintenance services. They suffer plastic deformation during unwinding of the reel, passing through a goosneck arch guide and an injector unit. Strain levels are of 2–3%, making the tu…
The incorporation of low molecular weight drugs and therapeutic peptides into multilayer films assembled via the layer-by-layer technique can potentially provide means to deliver small molecules to target sites and to tune their release. This study describes the use of both hydrophobic and electrostatic interactions t…
Mathematical modelling and stability analysis for the thermal separation process of laser cutting will be considered. The process can be modelled as a free boundary problem of non-linear 2D partial differential equations with two moving boundaries describing the dynamical behaviour of the arising melt flow. An approxi…
From an initial crystallographic study of a large family of ring-substituted 2-acetoxybenzoic acids, only one member - the 5-chloro derivative - showed polymorphism, with two forms (α and β) identified, the former having a marginally higher melting point. The two structures show a close 1-D similarity through a row of…
