“…This is due to the lowering of carrier lifetime in traps with increase in temperature, which increases the number of free carriers; consequently the transition from ohmic to non‐ohmic behaviour occurs at higher fields with increase in temperature 20. These results cannot be explained on the basis of space charge limited current, because the slope for this type of mechanism has been observed to be around two 21. The other possible mechanisms are, (a) charge carrier injection into the film from the contact via field‐assisted lowering of the metal insulator potential barrier ie Schottky–Richardson (SR) emissions, and (b) release of charge carriers from traps via field‐assisted lowering of trap depth ie the Poole–Frenkel (PF) effect.…”

Capacitors with an Al–polyimide–Al sandwich film structure have been fabricated: the top and the bottom aluminium electrodes were deposited by vacuum evaporation and the polyimide film was deposited by an isothermal immersion method. An X‐ray diffractogram of the film indicates the amorphous nature of the polyimide film. Dielectric and ac conduction properties of polyimide capacitors in the frequency range 10 kHz to 10 MHz at various temperatures (303–423 K) are reported; the dc conduction at different voltages and at various temperatures (303–423 K) is given. The capacitance of the film decreases with increasing frequency but increases with increasing temperature. The ac conduction studies suggest that electron hopping is responsible for conduction while the dc conduction studies reveal that Poole–Frenkel conduction is predominant at high fields. The activation and zero field activation energies are also calculated. © 2001 Society of Chemical Industry

Spectroscopic evidence revealing polyproline II structure in hydrophobic, putatively elastomeric sequences encoded by specific exons of human tropoelastin

Elastin, the protein responsible for tissue elasticity, is contained in arterial walls, lungs, and skin. Given the cassette like organization of the human tropoelastin gene, giving rise to alternating exons encoding for crosslink domains and elastomeric domains, it is tempting to suggest that polypeptides encoded by different exons could adopt structures independent of the other exons. The results obtained with the polypeptide sequences encoded by exons 3, 7, and 30 of human tropoelastin are described. It is shown that these hydrophobic exons may partly assume the polyproline II (PPII) structure, as found by circular dichroism studies in aqueous solution. Classical Raman spectroscopy evidences a specific sharp band at 1314 cm(-1), which is assigned to the PPII structure adopted by these exons in the solid state. As these sequences are among those putatively responsible for elastomeric properties, these findings are of particular interest in relation to the current models of the elasticity of elastin.

“…As the N9H bond stretches, the σ* energy curve descends and the π* energy curve rises, and the σ*‐ π* state crossing occurs at ∼1.22 Å, giving rise to a barrier for the N9H bond cleavage. For comparison, such energy curves have been calculated using the so‐called stabilization method 39–42 at the SCF level, using the 6‐31+G( d,p ) basis set. The results obtained from stabilization extrapolations indicate that the anion energy curves are similar to those depicted in Figure 8 and the σ* state intersects the neutral energy curve at ∼1.43 Å.…”

Flywheel energy storage systems can be used as an uninterrupted power supply system because they are environmentally friendly and have high durability. The use of a simple voltage sag compensator with a low‐speed heavy flywheel and a low‐cost squirrel‐cage induction motor/generator is proposed. First, the ability of the proposed system to maintain the load voltage at 100% when the grid is experiencing voltage sag is validated experimentally. Next, design guidelines for the flywheel stored energy are discussed. Experimental verification of a 50‐kW‐class system is carried out, and the results show good agreement with the developed design guidelines. © 2012 Wiley Periodicals, Inc.
