High Resolution Image Download MS PowerPoint Slide The use of conjugated organic compounds in fluorescence sensing applications has been demonstrated to provide an impressive method to detect energetic nitro-aromatic compounds. The amplified fluorescence quenching in conjugated polymers was used for trace detection of…
In this study, we devised a simple method to enhance the conductivity of poly(3,4-ethylenedioxythiophene)-poly(styrene-sulfonate) (PEDOT:PSS) films through spin-coating with various surface-modified compounds, and then applied this technique to the preparation of ITO-free polymer solar cells (PSCs). The electrical con…
An iron titanate catalyst with a crystallite phase, prepared by a co-precipitation method, showed excellent activity, stability, selectivity and SO(2)/H(2)O durability in the selective catalytic reduction of NO with NH(3) in the medium temperature range.
The electric field distribution of cable insulation systems under HVDC can be affected significantly at interfaces due to space charge build-up. In this article, the second part of a three-article series, face and space charge accumulation are analyzed first in terms of macroscopic physics, then through approximate ma…
The transport of oxygen in dense samples of yttria-stabilized zirconia (YSZ), of average grain size d ≈ 50 nm, has been studied by means of 18O/16O exchange annealing and secondary ion mass spectrometry (SIMS). Oxygen diffusion coefficients (D*) and oxygen surface exchange coefficients (k*) were measured for temperatu…
We report a two-step, solution-based synthetic method to fabricate CdS nanoparticles-sensitized ZnO nanowire heterostructure arrays which showed enhanced photocatalytic activities in comparison with bare ZnO nanowire arrays.
Tissue Engineering is a rapidly evolving field in terms of cell source and scaffold fabrication. As the template for three dimensional tissue growth, the scaffold should emulate the native extracellular matrix, which is nano-fibrous. Currently, there are three basic techniques capable of generating nano-fibrous scaffo…
Hollow mesoporous silica nanospheres (HMSNs) with tunable sizes of both sphere diameter (around 100 nm) and shell thickness have been successfully fabricated.
Gadolinium is widely employed as a contrast agent for magnetic resonance imaging (MRI) and has generally been considered to be safe. As with iodinated radiocontrast, concern for contrast-induced nephropathy existed with gadolinium-contrast as it possessed many similar qualities (hyperosmolar, renal excretion via glome…
Industrial nanoparticles are not developed to be compatible with in vitro cell culture assays which are carried out in isotonic solutions at physiological pH and often in the presence of proteins. The tendency of nanoparticles to deagglomerate or agglomerate is strongly sensitive to these parameters. The state of aggl…
Conceptual studies and numerical simulations are performed for imaging devices that transform a near-field pattern into magnified far-zone images and are based on high-order spatial transformation in cylindrical domains. A lens translating a near-field pattern from an almost circular input boundary onto a magnified fa…
Covalently functionalized carbon nanotubes (CNTs) wrapped in intumescent flame retardant were successfully fabricated and characterized. By adjusting the ratio of CNTs and flame retardant, the diameter of the functionalized CNTs was effectively controlled to 20–90 nm. Compared with pristine CNTs, the functionalized CN…
The two-step spin crossover of a new mononuclear iron(ii) complex is studied by magnetic, crystallographic and calorimetric methods revealing two successive first-order phase transitions and an ordered intermediate phase built by the repetition of the unprecedented [HS-LS-LS] motif.
The aim of this paper was to accurately analyze the sources of water pollution and loading concentrations in textile finishing mills.A process data collection was performed and integrated with a characterization of the process effluents in terms of treatability and reusability.In order to evaluate properly the wastewa…
The ability of 2,2'-bipyridine-bound copper(ii) ions to quench the photoluminescence of hydrophobic CdSe quantum dots is used to create a novel, selective turn-on fluorescence cyanide sensor.
The effects of carbon blacks on vulcanization and mechanical properties of filled ethylene-propylene-diene rubber (EPDM) are investigated, by comparing with five types of rubber-grade carbon blacks.Curing kinetics is studied by rheometer and the results indicate that the curing characteristics are influenced by combin…
A new type of multifunctional magnetic nano-platform for diagnosis and therapy applications was designed using bisphosphonate/carboxylic ligands.
In the presence of iodide ions, the cationic p-dimethylaminopyridine adduct of 1,3,5,7,8-pentamethylpyrromethene-boron fluoride [-DMAP](+) reacts with fluoride ions to afford the corresponding brightly fluorescent difluoride -F.
Cubic ordered mesoporous Co3O4, prepared via the nanocasting pathway using KIT-6 as hard template, was found to be an excellent catalyst for low temperature CO oxidation, with the activity clearly depending on surface area and pore systems of the catalysts.
Mixed spinel hydrophobic ZnxFe1-xO x Fe2O3 (up to x = 0.34) nanoparticles encapsulated in polymeric micelles exhibited increased T2 relaxivity and sensitivity of detection over clinically used Feridex.
