In this assessment, hybrid composites were prepared from the combination of industrial waste, as marble waste powder (MWP) with conventional fillers, carbon black (CB) as well as silica as reinforcing material, incorporated with natural rubber (NR). The properties studied were curing, mechanical and swelling behavior. Assimilation of CB as well as silica into MWP containing NR compound responde...

the idea of smart corrosion inhibition is basis on either inhibitor consumption where it is needed or reducing harmful matrix interaction with it. in addition, applying corrosion inhibitor in a coating causes many problems such as loss of inhibition capability, coating degradation, or both. a useful technique to overcome this problem is applying of inert host systems of nanometer dimensions as ...

Abstract This paper reports the results of effects oleamide addition on hardness, as one mechanical behaviours, styrene butadiene rubber/silica (SBR/silica) composite. The base SBR was compounded with silica, a reinforcing filler, and others compounding chemicals. silica into rubber matrix at 30 phr chemicals were added based semi-efficient formulation. has been done using opened two-roll mills...

Spherical mesoporous silica MCM-41 was synthesized for adsorptive removal of sulfur compounds from fossil fuels using 1mM solution of dibenzothiophene (DBT) in dodecane as model oil. The prepared silica adsorbent has been characterized by nitrogen adsorption-desorption analysis as well as Small Angle X-ray Scattering (SAXS), and transmission and Scanning Electron Microscopy (SEM) methods. R...

The present study synthesizes a novel adsorbent by coating Fe3O4 magnetic nanoparticles with amino functionalized mesoporous silica. The FTIR spectrums indicate that silica has been successfully coated on the surface of Fe3O4 and 3-aminopropyl tri methoxysilane compound have been grafted to the surface of silica-coated Fe3O4. The XRD analysis shows the presence of magnetite phase with cubic spi...

Present work is directed toward the isolation and identification of biological active (antimicrobial) compound from metabolite extracted from endophytic fungus Emericella qaudrilineata(RS-5) (Accession number KC662361). Crude extracted from endophytic fungus Emericella qaudrilineata possessing antibacterial activity was subjected to bioassay guided fractionation in which toluene fraction exhibi...

BACKGROUND The aim of this study was to synthesize Gd(3+)-based silica nanoparticles that conjugate easily with glucosamine and to investigate their use as a nanoprobe for detection of human fibrosarcoma cells. METHODS Based on the structure of the 2-fluoro-2-deoxy-D-glucose molecule ((18)FDG), a new compound consisting of D-glucose (1.1 nm) was conjugated with a Gd(3+)-based mesoporous silic...
