Improving the mechanical properties of epoxy-based adhesives with nanoparticles is one methods which justifies use adhesive joints significantly. This work studies strength adhesively bonded single-lap (SLJs) considering pure adhesive, reinforced nano-silica particles (NSPs), nano-clay (NCPs), and a combination both nano particles. Uniaxial tensile testing SLJs was conducted to reveal failure l...

background:  ramsar, a northern city in iran, lies on the coast of the caspian sea. this city has areas with some of the highest levels of natural radiation measured to date. the radon concentration in some areas of ramsar is up to 3700 bq m–3. on the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this city....

– Microscopy observations show that suspensions of synthetic and natural nanolayered smectite clay particles submitted to a strong external electric field undergo a fast and extended structuring. This structuring results from the interaction between induced electric dipoles, and is only possible for particles with suitable polarization properties. Smectite clay colloids are observed to be parti...

In nanocomposites, the interphase thickness may be comparable to size of nano-particles, and hence, effect layers on mechanical properties nanocomposites substantial. The nano-particle ratio variability across are most important affecting parameters overall behavior nanocomposites. this study, elastic elasto-plastic a polymeric clay nanocomposite (PCN) using functionally graded (FG) is investig...

INTRODUCTION Hearing protection devices are one of the primary noise reduction tools in developing countries. This study is intended to produce and apply acrylonitrile butadiene styrene (ABS)/clay nanocomposites to fabricate a laboratory single cup earmuffs and then compare it with double cup and single cup pure ABS earmuffs in terms of noise attenuation performance and comfort. In addition, th...

Rapid urbanization and requirement of infrastructure, stable construction sites are not available. Therefore, there is a dire need for improvement marginal soils to be used as material. However, weak comprise saturated clays, fine silts, loose sand, which susceptible failure pose problems stability. this research aims study the strength microstructural behavior soft treated with nano-alumina (A...

Objective: The objective of this study was to formulate and evaluate the Curcumin (CUR) encapsulated sodium alginate (SA)/badam gum (BG)/kaolin (KA) microbeads for controlled drug release studies.
 Methods: fabricated were characterized by fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray diffraction (X-RD), ele...
