An imaging protocol for dynamic contrast-enhanced breast MRI with 3.0T: using sagittal sequence interleaved between axial sequences
BACKGROUND: B1 transmission-field inhomogeneity has been reported at 3.0 Tesla (T) breast imaging. Enhancement measurements of breast cancers at 3.0T may be insufficient for some patients and improvements in imaging protocols are needed. PURPOSE: To quantify B1 inhomogeneities in normal tissue and malignant masses at…
Plasma polymerized thin coating as a protective layer of carbon nanotubes grafted on carbon fibers
Nanoparticles addition is widely studied to improve properties of carbon fiber reinforced composites. Here, hybrid carbon fiber results from grafting of carbon nanotubes (CNT) by Chemical Vapor Deposition (CVD) on the carbon fiber for mechanical reinforcement and conductive properties. Both tows and woven fabrics made…
Effect of Cross Sectional Shape on the Energy Absorbing Characteristics of a Tube under Quasi-Static Loading
In this study, numerical simulation of tubes of various cross section under axial compression is carried out using LS-DYNA. The effect of varying configurations of tube cross-section shape on the deformation response, collapse mode and energy absorption characteristics of tubes under quasi-static axial compression hav…
Effect of Mica Content on the Physical, Mechanical and Morphological Properties of Alumina-Cullet-Mica Ceramic
This research is conducted in order to determine the best composition of alumina-cullet ceramic with the addition of mica powder. The alumina-cullet-mica composites (ACMCs) were produced by using powder compaction method. All raw materials used such as alumina, cullet and mica for fabricating the samples were first mi…
Effects of Mig Welding to Corrosion Behaviour of Carbon Steel
This paper presents corrosion behaviour of welded low carbon steel at different welding parameters. Welding process was conducted using metal inert gas (MIG) technique at welding voltage range of 19 to 22 V with 1 V interval, and wire feed rate range of 90 to 120 inch per minute (ipm) with 10 ipm interval. Filler mate…
Managing Operating Procedures in Distributed Collaborative Projects
In recent years, large distributed collaborative projects have become very prominent in scientific research, allowing exchanges between laboratories located in different institutions and countries and between various domains of competence. Particularly the work on nanotoxicity – a field which has only been under inves…
Synthesis and Characterization of Filtered-cathodic-vacuum-arc-deposited TiO2Films for Photovoltaic Applications
Titanium dioxide (TiO 2 ) is well-known as a photovoltaic and photocatalytic material. For improvement in the dye-sensitized solar cell (DSSC) performance efficiency, the photocatalyst TiO 2 layer would be desired in nanoporous anatase. In this research, TiO 2 films were synthesized on glass or p-type silicon substrat…
Free energies, kinetics, and photoelectron-transfer properties, and theoretical and quantitative structural relationship studies of [SWCNT(5,5)-armchair-C n H20][R] (R = η2-C m Pd(dppf), η2-C m Pd(dppr), and η2-C m Pd(dppcym)2, n = 20 to 300 and m = 60 and 70) nanostructure complexes
Metal complexes containing one or several bis(triorganylphosphine)palladium fragments attached to the C 60 core and coordinated in olefinic η 2 mode have been previously described. The number of carbon atoms of the single-walled carbon nanotubes (SWCNTs) is the useful numerical and structural electrochemical propertie…
Scatterometry accuracy improvement using 3D shapes
A non-destructive and fast optical solution for characterization of high aspect ratio and isolated 3D hard disk drive writer head air bearing surface structure is presented in this paper. While 2D gratings are plagued by line bending and accuracy problems, the 3D scatterometry test structures show superior mechanical…
Metrology solutions for high performance germanium multi-gate field-effect transistors using optical scatterometry
In this work, we report the first demonstration of scatterometry Optical Critical Dimension (OCD) characterization on advanced Ge Multi-Gate Field-Effect Transistor (MuGFET) or FinFET formed on a Germanium-on-Insulator (GeOI) substrate. Two critical process steps in the Ge MuGFET process flow were investigated, i.e. a…
Broadening the scope ofActa Crystallographica Section C
created out of a merger of the Short Structural Papers, which had been included in Section B since 1972, with the successful journal Crystal Structure Communications, which had been published by the University of Parma, Italy, in the period 1972-1982. The new Section C adopted Crystal Structure Communications as its s…
