The current study focuses on the effect of Acrylate-styrene-acrylonitrile (ASA)/Nanosilica (Si) modified binders complex modulus (G*) and rutting resistance parameters (G*/ sinδ) Asphalt Cement (AC). Four different blends including base binder polymer nanocomposites which were formed by blending 5% ASA to with addition nanosilica at 3, 5 7% weight subject investigations. Conventional Dynamic Sh...

This work focuses on the reinforcement of polyoxymethylene (POM) by nanosilica particles (NS) in order to increase flexural strength and hardness POM matrix. Thermo - mechanical properties POM/NS nanocomposite were investigated using dynamic thermal analysis (DMTA).

With an ultrasonic frequency of 15 kHz and 850 W power capacity, the effects nanosilica particle inclusion on tensile, flexural, impact properties woven fiber-reinforced kenaf/carbon fiber/epoxy hybrid composites were explored experimentally. The nanoparticles dispersed uniformly in epoxy using probe. Test samples made according to ASTM requirements for three distinct weight compositions partic...

ABSTRACT Silicon is an inducer of plant resistance to arthropod pests, being a promising strategy for integrated management. The aim this study was evaluate the effect silicon on biological, reproductive and population aspects parental F1 generations two-spotted spider mite strawberry plants. Potassium silicate, nanosilica water were applied Two-spotted females confined leaf disks oviposition a...

Due to its unique qualities, concrete is the most extensively utilized substance in construction sector after water. However, because one ton of Portland cement produces about CO2, manufacturing process has considerable disadvantages. As a result, an alternative appears be required. Geopolymer new and environmentally friendly cementitious material that can used place cement. Chemically mechanic...

The present study revealed a low-cost process for utilizing desert sand preparing nanosilica by sol-gel technique. This work required sodium hydroxide, concentrated hydrochloric acid, distillate water as raw materials, and Iraqi sand. Nanosilica sample was characterized X-Ray Diffraction (XRD), scanning electron microscopy analysis (SEM), atomic force microscope(AFM), surface area (BET) method,...

to date, the effects of nanoparticles on woody plants remain unaddressed. this study reveals some of the physiological and biochemical effects of sio2 nanoparticles on wild pear seedlings. the seedlings were irrigated with different concentrations of nano silica (0, 10, 100, 500 and 1000 mg/l) for 14 days. nanoparticle adsorption and absorption, biomass allocation, gas exchange, relative water ...
