Recent efforts in the field of mesoscale effects on the structure and properties of thin polymer films call to revival interest in conformational structure and defects of a polymer backbone which has a crucial influence on electronic properties of the material.
(Chen et al., 2008) and sol-gel (Wu et al., 2007; Zhu et al., 2010) were reported. The PMN–PT thick-films were also prepared as single crystals by a modified Bridgman method and after the preparation they were bonded on Si substrates (Peng et al., 2010). The proper[r]
The UV-VIS absorbance spectrum confirms the exis- tence of silver nanoparticles inside the coating due to the presence of an absorption peak near 410 nm. Such narrow absorption bands are typical of silver nanoparticles and they are originated by the SPR phenomenon. EDX an[r]
Experiment In this study, Nd-doped SRSO thin layers were depos- ited at room temperature on p -type Si wafers by a reac- tive magnetron RF co-sputtering method that consists in sputtering simultaneously a pure SiO2 target topped with Nd2O3 chips. The Nd content was moni[r]
The role of cytoplasmic composition of anionic li- pids in membrane binding of K-Ras was evaluated by studying the effect of ATP depletion, which inhibits inward movement of PS, with consequent loss of plasma membrane asymmetry, and depletes ne[r]
+ The moleculars of this type, in the absent of external electric field, have not permanent dipole moment. They are called nonpolar moleculars . In a electric field the centers of positive and negative charges are displaced. As a result, the nonpolar mol[r]
Scanning electron microscopy was used to determine the difference between bacteria degradation by two types of particles presented in gaseous plasma, i.e. positively charged ions and neutral oxygen atoms. The source of ions was an argon ion gun with the ion energy of[r]
The research tendency has focused on improving carrier mobility rather than carrier concentration to enhance performance and response speed of TCO thin films. In this work, Indium, and Hydrogen co-doped ZnO (HIZO) thin films were deposited by using DC magnetron sputtering technique in hydrogen-plasm[r]
ϕ Ce io − int er ( | r i | ) , andu int O er = X i ϕ O io − int er ( | r i | ) . (2.8) The average nearest-neighbor distance at T = 0 K can be determined from experimentation or the minimum condition of the potential energy of the free surface layer composed of N Ce ato[r]
Using this general procedure and simple longitudinal-flow atmospheric reaction chambers (Figure 10.2), high quality YBCO films have been processed in short lengths at our laboratory and elsewhere (Paranthaman et al., 2000; Feldmann et al., 2001; Rupich et al., 2001;[r]
7.6 Discussion As explained in Chapter 2, there is no systematic data on the effect of molecular structure of the polymer film on their tribological properties despite some studies involving the tribological characterization of ultra-thin[r]
10.6.2 Adhesion Strength and Durability Measurements Using Microscratch Technique Scratching the surface with a fingernail or a knife is probably one of the oldest methods for determining the adhesion of paints and other coatings. In 1822, Friedrich Mohs[r]
The use of polymer-modified mortar and concrete (PMM and PMC) is investigated to improve the durability of concrete sewer pipes. The aim of the research is to ameliorate the resistance of concrete to biogenic sulphuric acid attack through polymer modification. Prior to the durability tests, experime[r]

both chemistry and topography on polymer films at dif- ferent scales ranging from nano to macro. Great promises in the field of biology are expected from this work: we have already validated that such surface was compatible with cell or bacteria development.[r]
testing ( Holdridge, 1953 ). The presence of montmorillonite usually in- creases the dry strength. Table 30 shows a range of transverse strength for different types of clay ( Ries, 1927 ). Shrinkage, both drying and firing, is another important property of
In this paper, firstly the electrical conductivities properties of Ag-NP doped in titania matrix will be investigated. Finally, the photo electrochemical properties and the mechanically strength of Ag-NP/TiO2 thin films whose heat treated at higher temperature (500, 600, and 700ºC) will be examined[r]
A series of D–A dyads and D–A–D triads molecular systems based on triphenylamine and 9-ethyl-carbarzole as donor (D) and BODIPY as acceptor (A) has been designed and synthesized. The optoelectronic properties including optical, electrochemical, and charge carrier mobility of these molecules have bee[r]
