Alloys 690 and 152 are the replacement materials of choice for Alloys 600 and 182, respectively. The latter two alloys are used as structural materials in pressurized water reactors (PWRs) and have been found to undergo stress corrosion cracking (SCC). The objective of this work is to determine the crack growth rates…
In this study, an experimental work is presented to determine the effects of fourteen different knit structures of 80% Lambswool-20% Polyamide knitted outerwear fabrics, on the dimensional properties; pilling resistance, abrasion resistance, bursting strength, air permeability and bending rigidity. The effect of relax…
Contractile dysfunction and cardiomyopathies secondary to apoptotic cell death are limiting factors for treating cancer with doxorubicin. Inhibition of volume-sensitive chloride currents (I(Cl,vol)) has been reported to blunt doxorubicin-induced apoptosis in cardiomyocytes. To investigate cellular contractility during…
The assembly reaction of a Mn(III) salen-type dimeric complex, [MnIII2(saltmen)2(H2O)2](ClO4)2 (saltmen2- = N,N'-(1,1,2,2-tetramethylethylene)bis(salycylideneiminate)), and a Ni(II) oximato complex, [Ni(II)(pao)2(phen)] (pao- = pyridine-2-aldoximate; phen = 1,10-phenanthroline), in the presence of NaBPh4 yielded a het…

Activated carbon monolith is widely used as adsorbent to enhance the storage capacity of natural gas,which greatly inspires the investigation on adsorption dynamics of methane on this type of adsorbents.The differential pressure permeation method was used to measure the surface diffusion coefficient.The impacts of Knu…
Spatially resolved electron energy loss spectroscopy experiments have given the measurement of the electromagnetic eigenmodes of individual metallic nanoparticles. The Electromagnetic Local Density of States has been measured with c.a 10 nm spatial accuracy over the whole near-infrared/ultraviolet regime.
With the advent of nano-particle fillers in insulating materials, the insulating materials of superior quality have come to fore. In the recent past, nanocomposite LDPE/XLPE (low density polyethylene/cross linked polyethelene) power cable dielectrics have been synthesized. A preliminary evaluation of these new class o…
The two-step reaction between LiH and NH(3)BH(3) in THF leads to the production of more than 14 wt% of hydrogen at 40 degrees C.
We report on the multiple ZnO nanowires field-effect transistors (FETs), which were formed by assembling as-synthesized ZnO nanowires on a SiO 2 /Si substrate using an optimized alternating current (AC) dielectrophoresis (DEP) technique in three-probe back-gate geometry. The AC DEP was optimized with a bias voltage of…
Recent advances in the area of chiral nano-building blocks are presented and discussed in the context of nanoscience and nanotechnology moving toward emerging functional applications of chiral nanomaterials, such as enantioselective catalysis, sensing and chirooptical devices. The emphasis is given to chiral nanoparti…
Renewable resources such as natural fibers in the field of fiber reinforced materials with their new range of applications represent an important basis in order to fulfill the ecological objective of creating eco‐friendly materials. In views of enormous advantages a study on green composites using Saccaharum cilliare…
Energy transfer from photoexcited porphyrin molecules to single-walled carbon nanotubes (SWNTs) has been experimentally detected for samples in aqueous Triton X-100 micellar suspensions. Addition of SWNTs to micelle-suspended porphyrin results in strong quenching of porphyrin fluorescence. Measurements of concentratio…
We report an approach to the design of 'charge-shifting' anionic polymers that provides control over the disruption of ultrathin polyelectrolyte multilayers in aqueous media. We demonstrate that the addition of citraconic anhydride to poly(allylamine) yields an anionic, carboxylate-functionalized polymer (polymer 2) t…
Modeling electromagnetic forming processes is in many ways simpler than modeling traditional metal forming processes. In electromagnetic forming the problem is often dominated by inertial acceleration by a magnetic field. This is a much better posed problem than the more traditional ones that are often dominated by co…
Treatment of 3- or 4-nitrophthalonitrile with 1,2:5,6-di-O-isopropylidene-alpha-d-glucofuranose or 1,2:3,4-di-O-isopropylidene-alpha-d-galactopyranose in the presence of K(2)CO(3) gave the corresponding glycosubstituted phthalonitriles. These precursors underwent self-cyclisation, or mixed-cyclisation with the unsubst…
The absolute extinction cross-section spectrum of a single nanoparticle measured using spatial modulation spectroscopy (SMS) is correlated with its transmission electron microscopy (TEM) image. The sizes of quasi-spherical particles obtained by the two methods are found to be in good quantitative agreement. The possib…
Several design–concepts are presented for so–called efficiency achromatized diffractive optical elements (EA–DOEs) possessing a diffraction efficiency larger than 97% over a broad spectral range. We start with tracing two different methods for surface relief profiles well known from the literature: common depth and mu…
The electron backscattering factor was measured from 24 different elements at low primary beam energy (250-5,000 eV). The results were compared with Monte Carlo simulations from a variety of freely available programs and an in-house developed program. The results suggest that a thin film of oxide can modify the backsc…
We describe a simple and versatile method to fabricate conducting polymer hydrogels via supramolecular self-assembly between polymers and multivalent cations; the as-prepared hydrogels are potentially applicable in the fields of electrosensors, chemical release and artificial muscles.
