This paper studies the recent investigations and development of combined application of Pozzolanic additions Nano-Silica (NS) and Fly Ash (FA) on the strength properties of concrete for sub sequential growth of concrete industry. This investigation not only saves the natural resources but also controls the environmental pollution by usage of wastes. The limited work is done on partial replaceme...

Electrochemical impedance spectroscopy and gravimetric methods were carried out to analyze water uptake of thin polyurethane films separately filled with either hydrophobic or hydrophilic nano-silica. Correspondingly the impedance spectra and gravimetric data were interpreted in terms of movement of water within the coating and/or to the coating/metal interface. Although the obtained results fr...

BACKGROUND Removal of mercury from aqueous environment has been highly regarded in recent years and different methods have been tested for this purpose. One of the most effective ways for mercury ions (Hg(+2)) removal is the use of modified nano porous compounds. Hence, in this work a new physical modification of mesoporous silica (SBA-15) with 1, 3, 5 (Trithiane) as modifier ligand and its app...

Silaffins are involved in the formation of the cell walls of diatoms. It is known that silaffins can precipitate silica in vitro, forming nano- and micro-particles in the shape of spheres and plates containing many pores. It is important to note that the deposition of silica and the particle morphology in the presence of silaffins affects chemical and physical agents (e.g., peptides, polyamines...

Cooling is one of the most important challenges in industries, especially in the automotive industry. The coolant which is used in engine radiators possesses lower thermal conductivity. To enhance the thermal properties, coolant was dispersed in nano-sized particles and the fluid is called as Nanofluid. In this Study, Silica Nanoparticle was dispersed in Paraflu Engine coolant usin...

background: multifunctional core-shell magnetic nanocomposite particles with tunable characteristics have been paid much attention for biomedical applications in recent years. a rational design and suitable preparation method must be employed to be able to exploit attractive properties of magnetic nanocomposite particles.objectives: herein, we report on a simple approach for the synthesis of ma...

Several studies have reported that amorphous nano-silica particles (nano-SPs) modulate calcium flux, although the mechanism remains incompletely understood. We thus analyzed the relationship between calcium flux and particle surface properties and determined the calcium flux route. Treatment of Balb/c 3T3 fibroblasts with nano-SPs with a diameter of 70 nm (nSP70) increased cytosolic calcium con...

The use of UHMWPE has attracted the attention of many researchers and industries. The aim of the present work is to fabricate UHMWPE/MoS2-Oxide nano-composites using in-situ polymerization. For this purpose, modified molybdenum disulfide was used. In order to perform the polymerization, a Ziegler-Natta catalytic system, with MoS2-Oxide and magnesium Ethoxide as support, was used. In order to fa...
