Dissolution and Repassivation Kinetics of a 12.3Cr-2.6Mo-6.5Ni Super Martensitic Stainless Steel
In this investigation, the dissolution and repassivation kinetics of a super martensitic (SM) stainless steel (Fe-12.3Cr-6.5Ni-2.6Mo) have been characterized using the artificial pit technique. As a part of this study, a diffusion model has been developed and employed for calculation of the pit surface concentration o…
NUMERICAL PATH-INTEGRATION CALCULATION OF TRANSPORT PROPERTIES OF STAR POLYMERS AND THETA-DLA AGGREGATES
Although the calculation of transport properties of complex-shaped particles (Smoluchowski rate constants for diffusion-limited reactions, Stokes friction coefficient, virial coefficients for conductivity, viscosity and other transport properties) is straightforward in principle, the accurate evaluation of these quant…
Duplex Hardening for Aerospace Bearing Steels
A new process, duplex hardening, was developed, for two steels which are already widely used for aerospace applications, M50 and M50 NiL. The rolling contact fatigue and sliding wear performance of duplex hardened bearing components were evaluated on M50 and M50NiL steels. The rolling contact fatigue and sliding wear…
Inhibitory effects of chitosan on superoxide anion radicals and lipid free radicals
With the electron spin resonance (ESR) technique, the inhibitory effects of chitosan on superoxide anion radicals and linoleic acid lipid radicals were found. The inhibitory ratio E for these two kinds of radicals is in proportion to the concentration of chitosan. It was also observed that E for linoleic acid lipid ra…
Distribution of Hydrogen Occluded in Bolts Tightened beyond the Yield Strength and Exposed at a Seashore Site
The distribution of hydrogen occluded in high strength bolts tightened beyond the yield strength and exposed for 9 years has been investigated to establish an evaluation method for delayed fracture property. Hydrogen thermal desorption analysis was employed for determining hydrogen content in specimens cut out from th…
Adsorption Behaviour of Laprol 2402 C on a Tin Electrode
SUMMARYVoltammetry and EIS were used to study the adsorption behaviour of laprol 2402 C (the copolymer of ethene and propene oxides) on a Sn electrode in strongly acid Sn(II) sulphate solutions. At least two states of adsorption layers were found to exist depending on cathodic polarisation. Adsorption of laprol, obser…
Hydrogen Storage in Carbon Single-wall Nanotubes
Carbon single-wall nanotubes (SWNTs) and other nanostructured carbon materials have attracted considerable interest recently due to several reports of high hydrogen storage capacities at room temperatures. Other reports indicate room temperature storage capacities are ~ 0 wt%. All in all, the reported capacities on th…
Improved Temperature Stability of Microwave Properties in Tunable Devices Using Substituted Ba 1− x Sr x TiO 3
An improvement in ferroelectric device technology has become possible through optimization of the properties of the ferroelectric materials used to make the devices. The improvements discussed herein impact true time delay line and phase shifter performance by enhancing control over dielectric constant and extending t…
Molten flux synthesis, single crystal X-ray structure and ion-exchange properties of the first polythiogallate, CsGaS3
A new polythiogallate, CsGaS3, has been synthesized using molten flux of caesium polysulfide, and structurally characterized, by single crystal X-ray diffraction techniques, as possessing one-dimensional GaS3− chains, built from GaS4 tetrahedra. Cs+ ions undergo facile ion-exchange, at room temperature, with Rb+, NH4+…
3D Simulation of a Shape Memory Microactuator
A three-dimensional (3D) model has been developed for simulation of the physical properties of an electrically driven shape memory alloy (SMA) microactuator used for control of a microvalve. The mechanical behavior is decribed by a two phase macromodel taking into account material and geometrical nonlinearity. The sim…
The Role of Lithium and Boron on the Corrosion of Zircaloy-4 Under Demanding PWR-Type Conditions
We report here the investigations on the corrosion of Zircaloy-4 cladding in out-of-pile and in-pile loops. Tests were conducted on the cladding in the fresh, preoxidized, and preirradiated conditions. The exposures were in low and high lithium coolant, with and without boron, and under single-phase and two-phase heat…
The enhanced photoluminescence of zinc oxide and polyaniline coaxial nanowire arrays in anodic oxide aluminium membranes
A novel nanomaterial, an array of zinc oxide (ZnO) and polyaniline (PANI) coaxial nanowires, was synthesized using an anodic aluminum oxide (AAO) membrane as the template. The morphology of these coaxial nanowires was observed with transmission electron microscope (TEM). The experiments on photoluminescence (PL) of co…
L-Tyrosine-based backbone-modified poly(amino acids)
Tyrosine-based pseudo-peptide polymers, first introduced in 1987 by Kohn and Langer, have been identified for potential biomaterial applications. These materials combine the desired polypeptide properties of biocompatibility, biodegradability, non-toxicity, and non-immunogenicity with good processing properties includ…
Nanoporous Surfaces of FeAl Formed by Vacancy Clustering
Numerous thermal vacancies are frozen into FeAl B2-ordered alloy ribbons by a conventional rapid-solidification technique. Through heat treatment at 723 K, clustering of the supersaturated vacancies generates a large number of nanopores, particulary near surfaces, thus creating nanoporous surfaces. The nanoporous surf…
Enzyme Inhibitors to Increase Poly-3-hydroxybutyrate Production by Transgenic Tobacco
Chemical regulation of secondary-metabolite synthesis was investigated through the improvement of poly-3-hydroxybutyrate (PHB) production in transgenic tobacco plants by the use of enzyme inhibitors. Two tobacco lines, BC3 and rCAB8, that produce PHB in both the cytosol and plastids were used. An acetyl-CoA carboxylas…
Defects and radiation induced electronic processes in magnesium aluminate spinel of different compositions
The time dependence of the formation and decay of irradiation-induced optical absorption centers in magnesium aluminate spinel single crystals of different compositions (MgO - 1.0Al 2 O 3 and MgO - 2.5Al 2 O 3 ) was investigated. The kinetics of accumulation of X-ray irradiation-induced absorption bands is consistent…
In Situ Electrochemical Strain Gage Monitoring of Actuation in Conducting Polymers
This paper reports on the first use of an in situ electrochemical strain gage method for the monitoring of the mechanical properties of conducting and redox electroactive polymers as they are switched between their neutral and oxidatively doped forms. Electrodeposition of three conducting polymers, specifically polypy…
Fabrication and Characterization of Diamond Quartz Crystal Microbalance Electrode
Boron-doped diamond film on a quartz crystal electrode was prepared by a reflow technique. The mass sensitivity of this diamond-quartz crystal microbalance (QCM) sensor was determined by performing electrodeposition.

Frequency Dependence of Viscoelastic Properties of Bread Crumb and Relation to Bread Staling
ABSTRACT The viscoelastic behavior of bread crumb was studied using dynamic mechanical analysis (DMA) in the compression mode with the frequency sweep. The dynamic storage modulus (E′), loss modulus (E″), and tanδ (E″/E′) were measured for bread crumb aged up to three days at ambient temperature. The viscoelastic prop…
