In this paper an investigation is presented based on numerical modeling of locally corroded tubular members. A parametric finite element approach was used in order to simulate behavior of damaged members under axial compressive loads. The results were then examined against an available experimental test. Validated mod…
There is considerable current interest in developing methods to integrate nanoparticles into optical, electronic, and biological systems due to their unique size-dependent properties and controllable shape. We report herein a versatile new approach for covalent immobilization of nanoparticles onto substrates modified…
Thermosensitive liposomes have been a popular area of investigation for several years leading to a plentitude of scientific literature and several patents. The majority of formulations are still in the early stage of development and preclinical testing, although one formulation, ThermoDox®, is significantly more advan…
To improve the accuracy of the neutron analyses for subcritical system with thermal fission blanket, a coupled neutron and photon (315 n + 42{gamma}) fine-group cross section library HENDL3.0/FG based on ENDF/B-VII, JEFF3.1 and JENDL3.3 was produced by FDS team. In order to test the availability and reliability of the…
A core fluids and heat transfer model has been developed for the prismatic high temperature gas reactor in support of the US NRC Next Generation Nuclear Plant (NGNP) evaluation model. The core fluids modeling relies on a subchannel approach in which the primary coolant flow path through the core region and vertical in…
Important safety parameters such as the fuel temperature coefficient (FTC) and the power coefficient of reactivity (PCR) of the CANDU-6 (CANada Deuterium Uranium) reactor have been evaluated by using a modified MCNPX code. For accurate analysis of the parameters, the DBRC (Doppler Broadening Rejection Correction) sche…
In this paper, the HELIOS/CAPP code system developed for the analysis of block type VHTR cores is presented and verified against several VHTR core configurations. Verification results shows that HELIOS code predicts less negative MTC and RTC than McCARD code does and thus HELIOS code overestimates the multiplication f…
In this work, we have reported a facile approach to fabricate the new Cu0.45Mn0.55O2 nanoparticles with novel properties. The detailed characteristic of the nanoparticles have been performed by X-Ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, transmission electron mi…
The high-capacity cathode materials with the same average composition of Li[Ni0.7Co0.15Mn0.15]O2 but with three different surface composition were prepared. The structural and electrochemical properties of the materials were studied using X-ray diffraction (XRD), scanning electron microscope (SEM), charge–discharge te…
A multilayered barrier structure stacked with organosilicon and silicon oxide (SiOx) films consecutively \nprepared using plasma-enhanced chemical vapor deposition (PECVD) was developed to encapsulate flexible plastic \nsubstrate. The evolution on the residual internal stress, structural quality of the organosilicon/S…
for reducibility of Co n+ . XRD reflections show the presence of impurities in the as-prepared samples while only rhombohedral phase could be identified in the samples after calcination at 700 °C. For all the glycine-to-nitrate ratios tested, the particle size estimated from XRD data ranges from 58-69 nm, which are sy…
The coherent (Rayleigh) to incoherent (Compton) scattering cross-section ratio of elements in the range 6 � Z � 82 for 59.54 keV gamma photons,have been measured. An HPGe gamma detector, placed at 90° to the incident beam, detects gamma photons scattered from the target under investigation. The intensity ratio of Rayl…
There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator can be placed at different offset distances from the beam, external actuators produce more bendin…
We have successfully synthesized CoFe2O4/BaTiO3composite nanoparticles with core-shell structure using a new organosol crystallization method. The weight fraction of the ferroelectric and the ferrimagnetic phase was 80% and 20%, respectively. The nanopowders were sintered to form a ceramic composite. The ceramics exhi…
A transformer's failure can lead to disruption in power, decrease in system reliability and monetary loss to the utility and distribution companies. Fault detection of transformers is a critical step for improving the reliability of distribution systems. Regular maintenance checks can detect most of faulty conditions,…
The first step of a methodological approach to the validation of the metal magnetic memory (MMM) method in non-destructive testing (NDT) applications and in systems used for the diagnosis of early stages of material fatigue in mechanical constructions (structural health monitoring, SHM, and prognosis health management…
This paper investigates the inrush currents of three-phase (a)symmetric multi-leg transformer cores considering magnetic core structure (e.g., three-leg vs. five-leg) and switching effects (e.g., recloser operating). The electromagnetic steady-state and transient behavior of three-phase transformers significantly diff…
Shunting discharge plasmas are metal plasmas that can be generated around a conductive rod at a reduced pressure on the order of 0.1-100 Pa. Even at atmospheric pressure, a plasma can be generated because the rod is heated to emit metal vapor so as to generate gas breakdown around the rod. When the temporally increasi…
Three new 8-O-4'-neolignans, fargesiphenols A-C, together with six known neolignans, were isolated from the flower buds of Magnolia fargesii. The structures were elucidated by spectroscopic methods, including extensive 1D and 2D-NMR techniques. Compounds were also tested for their anti-HIV-1 activities and cytotoxicit…
New coordinating relationships are obtained for the dimensional dependences of melting temperature T(r) and interfacial tension σ SL (r) of a solid spherical nanoparticle at the boundary with its own melt. The Thomson formula for T(r) and the Tolman formula for σ SL (r) follow from the expressions obtained at large ra…
