The manuscript describes pyrolysis of copolymers based on selected alkyl methacrylates containing C 1 -C 8 alkyl side chain at temperatures between 250 °C and 400 °C which was studied using pyrolysis-gas chromatography. The kind and composition of thermal degradation products gave practical information about the mecha…
The flame-retardant mechanisms of aluminium hydroxide (ATH) and magnesium hydroxide (MH) that used as typical inorganic fire-retardant were illustrated. The preparation methods of the fire-retardants are reviewed. And the modification approaches and future development direction of the fire-retardants were also discuss…
This paper describes an approximate 2D method for computing the magnetizing zero-sequence impedances in 3-phase core-type transformers without tank. These transformers do not have axial symmetry in their geometry, but a 2D model with axial symmetry is applied in order to obtain approximate results. The 3D models requi…
The rhenium- and ruthenium-containing catalysts are active in the oxidation of CH x and CO and in the reduction of NO x . Comparative testing of catalyst samples under laboratory conditions and on an engine stand demonstrated that these catalysts outperform the known commercial catalysts in the neutralization of exhau…
We studied the heat propagation in Ti/Pt/Au micro-heater embedded thermal testing chips by computer simulations. Graphene was considered to be incorporated within the chips as a heat spreader in order to utilize its extremely high thermal conductivity. The classical heat conduction equation was solved numerically usin…
The optimal choice of switches within a hysteresis controller with a d-q-related constraint is discussed in this paper. The hysteresis controller controls a bidirectional two-level three-phase standard inverter. This paper expands the options of switching processes to a former published d-q-hysteresis controller. Desp…
We have investigated the relationship between the catalyst and the growth of CNCs. It is found that with the increase of deposition time the yield of CNCs gradually increased, while their growth rate decreased exponentially. The short reaction time would lead to the growth of CNCs with smaller coil diameters, however,…
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…
