We discuss a class of phase computer-generated holograms for the encoding arbitrary scalar complex fields. describe two this that allow high quality reconstruction encoded field, even if they are implemented with low-resolution pixelated modulator. In addition, we show one these can be appropriately modulator limited by reduced depth.
In this study, we focus on qualitative differences in the network structure and dynamics of natural as well poly(butadiene) rubber dependence cure system (sulfur/accelerator or organic peroxide) used vulcanization process. The spatial homogeneity distribution chemical physical cross-links is assessed via quantitative measurement proton−proton residual dipolar couplings measured by static multiple-quantum (MQ) NMR spectroscopy at low field. experiment also provides information apparent...
The evolution of hydrogen bonding with temperature in three copoly(ether−urea)s no phase separation has been studied by Fourier transform infrared spectroscopy (FT-IR) the region carbonyl absorption urea groups. Assignment bands was made supposing existence chains groups linked bifurcated bonds. Quantum mechanical calculations these fitted qualitatively experimental results. Dynamic and calorimetric experiments showed that apparition band related to "internal" produces a decrease glass...
Elastomeric composites have been prepared using pre-treated fumed silica as a reinforcing system. The processing disadvantages of were overcome by novel one-pot modification method based on silanization treatment particles after an ultra-high energy sonication process that breaks down the micro-aggregates/agglomerates pristine into nanoparticles. Grafted organosilane molecules nanoparticle surfaces avoid natural tendency for to re-agglomerate obtaining stable dispersion organo nanosilica are...
This paper presents an integrated tunable hybrid multi-laser module designed to simultaneously generate multiple radiofrequency (RF) local oscillator (LO) signals through optical heterodyning. The device consists of five InP/Si3N4 lasers, each incorporating intracavity wavelength-selective filter formed by two micro-ring resonators. Through beating the wavelengths generated from three these we demonstrate simultaneous generation LO within bands crucial for satellite communications (SatCom):...
Abstract The scope of this paper is to review peroxide curing diene elastomers. At high dicumyl loading and temperature, changes in the crosslinking mechanisms were observed. Both Abstraction allylic hydrogen addition double bond can act as crosslinking. IR spectroscopy reveals a significant decrease bonds, new relaxation at temperatures above Tg elastomers present.
The combination of reinforcing fillers is one the most promising tendencies in elastomer reinforcement, where a synergic effect between them desired. Up to now, use mixed has been focused on preparation dual based complex synthesis process silica particles are situ generated carbon black matrix. In this paper, filler systems prepared following straightforward methodology, gradually and partially substituted by modified fumed silica. presence with different surface energies significantly...
In this study, wettability behavior of B 4 C substrate as well C/crystalline rice husk ash and C/amorphous substrates with two aluminum alloys were studied. The electrical resistivity, thermal expansion coefficients, diffusivity bilayer Al/B C/rice composite fabricated by one-step pressureless infiltration measured the obtained data systemically analyzed using Taguchi method analysis variance. Boron carbide after addition amorphous or crystalline display good molten alloys. results show...
Abstract The scope of this article is the study peroxide curing two nitrile rubbers with low and high content. efficiency can be much higher than one, polymer structure determines mechanism cross‐linking. In rubber content, radical may give rise to a polymerization reaction between adjacent double bonds generating heterogeneous network negative effect on vulcanizate properties. On contrary, in it not present or lesser extent, their vulcanizates show good physical © 2005 Wiley Periodicals,...
Abstract There is a need in the industry to advance technology underreaming, specifically operations where simultaneous drilling and underreaming take place. Underreaming hurdles have existed for several years that could not be overcome by simple reliable mechanical apparatus activate or deactivate tools. Activating tool on demand offers options techniques can enhance way wells are drilled. Traditional underreamers activated deactivated dropping steel ball via drillstring. The dropped...
