The phenomenon of high optical transmission through periodic structure on base of metallic diffraction grating was provided for TE polarization. It is shown that resonant transmission occurs only as a result of waveguide effect. There is certain a slit width where possible waveguide effect and consequently high transm…
The objective of this study is to determine the mechanical and physical properties of Particleboard made from modified particle of Kelampayan ( Neolamarckia cadamba ). The particles were modified with Silane and Sodium Hydroxide (NaOH) by soaked the particle for 24 hours with different ratio ( Kelampayan + Silane, Kel…
We investigate the transport properties through monolayer and bilayer graphene superlattices modulated by an in-plane homogeneous electric field based on the transfer matrix method. It is found that the angular range of the transmission probability through a graphene superlattice can be effectively controlled by the n…
In this work, we use 3D finite difference time domain (3D-FDTD) to calculate the plasmon resonance effect for a single silver hemisphere in which the palsmon line shape have distinct peaks when the particles are located on a glass substrate. The dependence of the resonance on hemisphere size and the ratio of height ov…
The content of magnetic fiber is the determinate element of both the surface magnetic field intensity and the economic cost of the magnetic fabric. It probably has certain influence on fabric wearability. In this study, experimental method has been adopted to investigate the wearability of knitted magnetic fabric whic…
Austenitic stainless steels are susceptible to microbiologically influenced corrosion (MIC) when they are in contact with sea water. This is due to the changes in the chemistry of the environment at the metal surface because of the settlement and activities of microorganisms. The thrust of our work was in understandin…
The mechanical behaviors of polytetrafluoroethylene (PTFE) in compressive test performed at different strain rates ranging from 10−2 s−1 to 103 s−1 are studied. The experimental results show that the yield strength increases with the increase in strain rate and exhibits a bilinear dependence on the logarithms of the s…
Polyurethane not only has applications including tires and insulation, but also is an essential element of our lives. Based on previous reports, some strains of fungus including Pestalotiopsis microspora have been reported to degrade this plastic. The ultimate objective is to create a genetically engineered variant of…
Experimental data on hydrogen chloride absorption by calcium-containing sorbents in solid fuel gasification in a continuous filtration combustion reactor are presented. The addition of the sorbents to the stock allows up to 80% of the chlorine to be sorbed. The chlorine remains as calcium chloride in the solid combust…
Recycled polypropylene/microcrystalline cellulose (rPP/MCC) composites were prepared by adding different loadings of maleic anhydride grafted polypropylene (MAPP) coupling agent. The tensile, impact and morphological properties of the composites were investigated. The obtained results show that the tensile and impact…
Oxidative thermal degradation and flame retardant behavior of cotton with intumescent formulations containing nanoclay as well as biodiesel (B0, B23, and B100) are studied by thermogravimetry (TG), differential thermal analysis, and limiting oxygen index (LOI). Activation energy of thermal degradation of cotton and co…
This essay describes the findings of generating the electrode composite of polyaniline/activated carbon fiber ( PANI/ACF) by repeatedly immersing eigenstate PANI into the solution of NMP and CHCl 3 added with VC. A samples surface profile and structure were represented using SEM and FT-IR. Thereafter the composite was…
The SiMo cast iron with 5.45 wt% of Al has been developed for using as an automotive exhaust manifold. Cyclic oxidation test of that alloy and the conventional SiMo cast iron was conducted at 850 oC in 5%CO 2 +12%O 2 +83%N 2 and 10%CO 2 +12%O 2 +78%N 2 . It was found that oxidation kinetics of the SiMo cast iron alloy…
An oxide dispersion strengthened steels are one of the most promising high temperatures, and high performance advanced structural material being developed for future fast reactors and high-temperature Generation IV reactors. In the present work, the corrosion resistance and its correlation with the passive film compos…
The 11B NMR method is used to study the crystals of trigonal alumina borates Ho1−x Y x Al3(BO3)4 (x = 0, 0.5, 1). The temperature-field evolution of quadrupole and hyperfine interactions in these compounds is studied and described.
Este trabalho tem como objetivo investigar propriedades físicas (densidade volumétrica e absorção de água) e mecânicas (módulo de elasticidade e resistência à compressão) de materiais compósitos particulados em matriz epóxi reforçados com serragem de madeira, cimento Portland e silicato de magnésio. Um planejamento ex…
The crystal structure of the third polymorph of dibenzylsquaramide (Portell, A. et al., 2009 ), (fig. 1) has been determined from laboratory X-ray powder diffraction data by means of direct space methods using the computing program FOX. (Favre-Nicolin and Černý, 2002) The structure resolution has not been straightforw…
We propose a physical address format suitable for the separated guide layer of a multilayered optical disc. Since the track format of the guide layer is different from that of conventional multilayered discs, a novel address format is required. The proposed format adopts a land-and-groove-track structure to generate a…
This paper reviews the emerging applications of mesoporous silica materials to be as adsorbents for heavy metals removal from the wastewater. Functionalization of the ordered mesoporous silica with organic or hybrid function groups provides new opportunities for fine-tuning the chemical, physical and mechanical proper…
Abstract Below are described results of the analysis concerning the use of two cored wire injection method (2PE- 9) and the unique application of a drum ladle as a treatment, transport and casting one, instead of a vertical treatment ladle. Parameter optimization, like: length of nodulariser wire, residual magnesium c…
