TiO2 is the most studied semiconductor material for photovoltaics and photocatalyst applications, but due to a very large electron hole recombination process it is difficult to use it as a photovoltaics material. In this context graphene-decorated Ag-doped TiO2 nanostructures have been synthesized by a simple, cost ef…
The effect of electron doping by the substitution of Rh for Ru on unconventional magnetic order in CeRu2Al10 was investigated via neutron powder diffraction. In Ce(Ru1-xRhx)2Al10 with x = 0.05, 0.12, and 0.2, reorientation of the ordered moment from the c- to the a-axis takes place in all samples, while the ordering v…
ABSTRACT The effectiveness of using interleaved nylon veils to increase the interlaminar toughness of glass fiber reinforced, low‐styrene emission unsaturated polyester resin composites has been investigated. Samples were manufactured by a hand lay‐up technique followed by compression moulding. Nylon 66 veils were use…
Matrix-addressed capacitive sensing is popularly employed in advanced multi-touch panels. While the number of simultaneous touch points of a passively addressed matrix is limited, the simultaneous touch points of an actively addressed matrix are constrained only by the size of the matrix and can be more densely packed…
Pectins, forming a matrix for cellulose and hemicellulose, determine the mechanics of plant cell walls. They undergo salient structural changes during their development. In the presence of divalent cations, usually calcium, pectins can form gel-like structures. Because of their importance they have been the subject of…
Mathematical modeling of the methane-combined reforming process (steam methane reforming–dry reforming methane) was performed in a fluidized bed membrane reactor. The model characterizes multiple phases and regions considering low-density phase, high-density phase, membrane, and free board regions that allow study of…
Abstract A facile and rapid approach for detecting low concentration of iron ion (Fe3+) with improved sensitivity was developed on the basis of plasmon enhanced fluorescence and subsequently amplified fluorescence quenching. Au1Ag4@SiO2 nanoparticles were synthesized and dispersed into fluorescein isothiocyanate (FITC…
In this paper, surface plasmon polariton (SPP) modes on silver nanowire (AgNW), with different field symmetric, are studied by different near field methods, respectively. In the experiment, the excitation and detection of SPPs are performed by two probes of near field scanning optical microscope (NSOM) simultaneously,…
Competitive adsorption of prototype molecules such as (12)CO, (13)CO and CO2 at the two typical fivefold coordinated Ti5c(4+) cation sites of reduced rutile TiO2(110) surfaces was studied in a newly designed UHV-FTIR system. The measured binding energies of (12)CO, (13)CO or CO2 adsorbed at two kinds of Ti5c(4+) sites…
Bacterial cellulose (BC) has been studied widely for applications in biomedical materials such as prosthetic artificial blood vessels owing to its unique characteristics, which include nontoxicity and nonimmunogenicity as compared with synthetic biopolymers such as expanded polytetrafluorethylene (ePTFE). However, to…
The effects of antimony (Sb) doping on solution-processed indium oxide (InOx) thin film transistors (TFTs) were examined. The Sb-doped InSbO TFT exhibited a high mobility, low gate swing, threshold voltage, and high ION/OFF ratio of 4.6 cm2/V s, 0.29 V/decade, 1.9 V, and 3 × 107, respectively. The gate bias and photob…
Abstract New ruthenium(II) photosensitizers [Ru(dcbpy)(L)(NCS)2] (dcbpy = 4,4′‐dicarboxylic acid‐2,2′‐bipyridine; L = 4,4′‐bis{di[4‐(N,N′‐dimethylamino)phenyl]amino}‐2,2′‐bipyridine (1), 4,4′‐bis[di(4‐methoxyphenyl)amino]‐2,2′‐bipyridine (2), and 4,4′‐bis[di(4‐tolyl)amino]‐2,2′‐bipyridine (3)) were prepared and charac…
Four sets of R.F.-sputtered CdS/CdTe thin-film solar cells are activated through comparable treatment procedures. Two samples were rinsed into deionized water for an hour before CdCl2treatment and then activated in Ar or air ambient. The two others are normally treated and activated in Ar and air, respectively. The in…
Polymeric scaffolds used in regenerative therapies are implanted in the damaged tissue and submitted to repeated loading cycles. In the case of articular cartilage engineering, an implanted scaffold is typically subjected to long-term dynamic compression. The evolution of the mechanical properties of the scaffold duri…
Polacrylamide nanocomposite hydrogels were prepared by in situ free radical polymerization reaction in presence of Spirulina microalgae, which is immobilized in montmorillonite clay (Sp-MMT). The nanocomposite hydrogel having 1 wt.% Sp-MMT clay was found to have desired exfoliated structure, maximum swelling and impro…
Abstract In this numerical work, a population balance‐based model is proposed in order to describe the cellulose particles size evolution during the enzymatic hydrolysis. Two kinds of actions are considered: endoglucanase activity that cleaves randomly β‐1,4‐glycosidic linkages of cellulose, and exoglucanase activity…
Two series of novel phosphorescent polymers have been successfully synthesized by the Suzuki cross-coupling reaction among functionalized phosphorescent IrIII ppy-type (ppy = 2-phenylpyridine anion) complex monomers with hole-injection/transporting (HI/HT) properties, fluorene-based silane moieties and triphenylamine-…
A simple and green approach was employed for the synthesis of Nitrogen doped graphene supported Ag nanoparticles (Ag-NG). The electrochemical behavior of Ag-NG modified glassy carbon electrode (Ag-NG/GCE) was investigated by cyclic voltammetry (CV). An obvious advantage of this nonenzyme electrode was that the Ag-NG n…
MOTIVATION: Recently, we made synthetic proteins from non-coding DNA of Escherichia coli. Encouraged by this, we asked: can we artificially express pseudogenes into novel and functional proteins? What kind of structures would be generated? Would these proteins be stable? How would the organism respond to the artificia…
This paper describes the application of the finite-elements method for determining the distribution of losses over windings and a detailed thermal-hydraulic network model for determining the value of the hot-spot factor and the hot-spot temperature. The influence of nonuniform losses in the conductor of the windings a…
