In the early 1960s, application of electrochemistry to corrosion was limited to the open-circuit potential measurements, the Stern and Geary methods, and the plot of current-voltage curves with the recently invented potentiostats. These techniques were totally unable to provide a reliable description of the intricate…
This paper deals with chain graph models under alternative AMP interpretation. A new representative\nof an AMP Markov equivalence class, called the largest deflagged graph, is proposed. The\nrepresentative is based on revealed internal structure of the AMP Markov equivalence class. More\nspecifically, the AMP Markov e…
Dehydrogenation of five species including CH3OH, CH3O, H2COO, NH3, and H2O over clean and oxygen-modified copper surfaces has been investigated by the first-principle density functional calculations within the generalized gradient approximation. The reaction enthalpies and the activation energies have been calculated…
This paper describes two methodologies for increasing the actuation speed of the shape memory alloy (SMA) actuator in ambient environment. The first method involves the implementation of a simple, light-weight heat sink, which consists only of a combination of an outer metal tube with the silicone grease, but able to…
With homoligand TbL3 and heteroligand complexes TbL3(Q)n (HL = HSal (salicylic acid) and HPA (2-anilinobenzoic acid); Q = TPPO (triphenylphosphine oxide) and TOPO (tri(n-octyl)phosphine oxide); n = 1 or 2) as examples, it was shown that heteroligand complexation affects not only the thermal and photoluminescent proper…
Abstract The grain boundary morphology of a cylinder‐forming poly(styrene block ‐isoprene) (SI) diblock copolymer was investigated using transmission electron microtomography (TEMT). The three‐dimensional (3D) morphologies of the grain boundaries between the two grains with different orientation angle, α, were investi…
The gamma ray buildup factors are represented by an approximation method to speed up calculation using the point attenuation kernel method. The fitting parameters obtained by the GP formula and Taylor's formula are compiled in ANSI/ANS 6.4.3, available without any limitation. The GP formula featured high accuracy but…
A simple method to measure electrical conductivity of conducting organic films has been described. A setup, based on four-probe technique, is specifically designed and fabricated for nondestructive electrical conductivity measurements of freestanding thin films. The current-voltage and temperature dependent characteri…

This work focuses on the fundamental studies of heterogeneous adsorption characteristics of mesoporous adsorbent. MCM‐48 was synthesized to investigate the adsorption properties of eight different volatile organic compounds (benzene, cyclohexane, n‐hexane, toluene, methanol, acetone, methyl ethyl ketone (MEK), and tri…
Light emitting diodes (LEDs) coated with Sr2MgSi2O7:Eu2+,Nd3+ (blue), SrAl2O4:Eu2+,Dy3+ (green), SrS:Eu2+,Y3+,Ce3+ (orange), and CaS:Eu2+,Tm3+,Ce3+ (red) long persistent phosphors were prepared. LEDs which have a 450nm blue emission were used as an excitation source for the coated phosphors. Blue (475nm), green (520nm…
Abstract Modified natural oils ‐ epoxidized soybean and rapeseed oils were tested as reactive diluents for viscosity regulation of Bisphenol A‐based low‐molecular‐ weight epoxy resin. Satisfactory viscosity reducing ability of epoxidized oils as well as non‐Newtonian rheological behaviour of the resin diluted with mod…
Amorphous GeOx∕SiO2 multilayers were prepared by successive evaporations of GeO2 and SiO2 powders onto substrates maintained at 100°C. The evolution of the structure was investigated by x-ray reflectometry, transmission electron microscopy, infrared-absorption spectrometry and Raman spectrometry for annealing temperat…
Abstract Summary: A new class of fibre reinforced commodity thermoplastics suited for injection moulding and direct processing applications has been developed using man‐made cellulosic fibres (Rayon tire yarn, Tencel, Viscose, Carbacell) and thermoplastic commodity polymers, such as polypropylene (PP), polyethylene (P…
Amorphous and crystalline vanadium pentoxide (V2O5) thin films weregrown onto heated glass substrates using spray pyrolysis technique. Aqueoussolution of ammonium meta-vanadat with different concentrations rangingfrom 0.1 to 0.5M was used. X-ray diffraction study of c-V2O5 revealedpolycrystalline films of orthorhombic…
The Polyaniline-sulfuric acid-glucose oxidase (PANI-H2SO4-GOD) electrode has been investigated in the present work. Platinum electrode was used for the synthesis of Polyaniline-sulfuric acid (PANIH2SO4) film using Potentiometric method with 0.2 M aniline, 1.0 M H2SO4 solution, 1.0 pH and 1 mA/cm2 applied current densi…
Pavement friction during wet conditions continues to be a major safety concern for pavement design and maintenance. The skid resistance of pavements is commonly measured using ASTM E 274, Skid Resistance of Paved Surfaces Using a Full-Scale Tire. However, there are no standard test procedures for evaluating the fricti…
The phase relationships in the LaFeO 3 -LaSrFeO 4 system at temperatures in the range 1000–2100°C in air are investigated, and the phase diagram of the system is constructed. One perovskite-like compound, namely, La 2 SrFe 2 O 7 , which belongs to the Ruddlesden-Popper phases, is revealed in the system.
Abstract It was observed the formation of polymeric films derived from 4‐aminophenol on the graphite electrode in aqueous medium (pH 0.5, 8.0 and 12.0). The electrochemical behavior of formed films was studied by voltammetry cyclic and impedance. These analyses indicate that the preparation in acid medium favors the c…
Methods for piezoelectric characterization include the standard resonance test. At higher powers, however, the material’s inherent nonlinearity acts to significantly affect the expected resonance response. High-power resonance methods have previously been developed to describe piezoelectric nonlinearity. In this artic…
