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 CHCl3 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%CO2+12%O2+83%N2 and 10%CO2+12%O2+78%N2. It was found that oxidation kinetics of the SiMo cast iron alloyed with 5.4…
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…
Silicone rubber have been aged in air while under 25% compression at temperature up to 250°C. These studies examined the compression set of silicone rubber at accelerated (elevated) temperatures and were then used to make predictions about compression set at room temperature. The data obtained could be amenable to tim…
Nanoparticles are presently being studied for optical and biomedical applications such as medical imaging and drug delivery. Nanoparticles impact the cellular environment due to many variables such as size, shape, and composition. How these factors affect cell viability is not fully understood. The purpose of this stu…
To identify possible spin texture contributions to thermoelectric transport, we present a detailed temperature and pressure dependence of thermopower S in MnSi, as well as a low-temperature study of S in a magnetic field. We find that S / T reconstructs the phase diagram of MnSi encompassing the Fermi liquid, partiall…
Mesoporous inorganic alumina with framework walls has been synthesized using a new and simple non-supercritical drying method. As a substitute solvent, hexamethyl disilylamine (HMDS) plays a definitive part for synthesis of the mesoporous alumina due to its special characters. The resulting alumina product shows high…
Abstract Environmental professionals are often tasked with projecting the cost to bring a contaminated site or portfolio of sites to regulatory closure. Fortunately, there are a number of useful guidance documents and industry publications available to assist in such cost projections. However, the usefulness of such t…
Korea (KO) has developed and participated in the Test Blanket Module (TBM) program in the ITER, in which Ferritic Martensitic (FM) steel was used as the structural material for the TBM first wall (FW). To develop the fabrication method for the TBM FW and verify its integrity, a half-scale sub-module mock-up was fabric…
In the last years EU started a new effort for the definition of a Roadmap for the fusion beyond ITER up to the construction of the DEMO reactor. The blanket technology, key issue for the development of the fusion breeder reactor, is an important part of this review. In the last 10 years the R&D of EU in blanket has be…
The effective conductivity and the photoconductivity in two-dimensional macroporous silicon structures have been measured, and their dependences on the macropore concentration and diameter have been calculated. The effective conductivity of macroporous silicon structures is found to decrease as the concentration and t…
