The influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. The incorporation of nanoclay into epoxy enhances the impact resistance of the composites. The impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...

Silver nanoparticles were synthesized via laser ablation in two different organic solvents (tetrahydrofuran and toluene). The influence of solvent choice on the production behavior silver dispersed a polystyrene matrix was investigated. UV–Vis spectroscopy, ellipsometry scanning probe microscopy techniques used for characterization. nanoparticles’ optical properties modified by existence core-s...

Calcareous sand is developed by the fracture of marine biological skeleton under impact seawater. not transported in process deposition. Therefore, calcareous retains characteristics skeleton, low strength, and porous. In order to study effect nanoclay cement on modification sand, a series tests were carried out modified (CCS) with different content nanoclay. this study, triaxial mechanical pro...

Titania, single-doped and lanthanum-silver co-doped titania nanocomposite were coated on cellulosic and polyacrylonitrile fibers via sol–gel method. The prepared samples were evaluated using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photolumines...

* Corresponding Author Email: [email protected] Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide (MBA) as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and magnetic montmorillonite ( mMT)...

Nanoparticles (NPs) of noble metals can strongly absorb visible light because of their plasmon resonance, which is greatly influenced by their morphology and size. The phenomenon of plasmon resonance gives rise to important applications such as colorimetric sensors, photovoltaic devices, photochromic devices, and photocatalysts. Noble metal NPs exhibit characteristic optical and physical proper...

Abstract Nanopowders doped with silver were produced by the method of pulsed electron beam evaporation. The pore sizes nanoparticles 25-32 nm. Evaluation photocatalytic and cytotoxic properties on cells was carried out. prospects using multimodal nanopowders as a agent, well for use in medicine, have been shown.

Abstract The work is devoted to the creation of a laser method for monitoring virucidal properties nanocoatings medical instruments. relationship between intensity spectra washes from silver-doped coatings and concentration pathogens was studied. Plasmon resonance obtained using DFB in order be able develop this method.

The performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. Therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. One common method of improving the performance of asphaltic mixtures is using different types of ...

In the current study the effect of nanoclay content and carbon fiber orientation on the buckling properties of epoxy/nanoclay/ carbon fiber orientation is investigated. Buckling samples were prepared with 1, 3 and 5 wt% of nanoclay and 0, 30 and 45 degrees of fiber orientations based on VARTM technique. The results obtained from the buckling tests showed that adding 1wt% of nanoclay into the pu...
