MgFe2O4 nanoparticleswere synthesized by a solution combustion technique, taking precursor nitrate and fuel in appropriate ratio and TiO2 nanoparticles are prepared by wet grinding technique and the composition of MgFe2O4/TiO2 nanoceramic prepared by mechano chemical synthesis and are taken in equal wt%, x=0.5. The process was a simple, convenient, environment friendly, inexpensive and efficien...
A facile method to produce conformal coated reduced graphene oxide (rGO) on vertically aligned titanium oxide (TiO2) nanotubes three dimensional (3D) arrays (NTAs) is demonstrated for enhanced field emission display applications. These engineered nano arrays exhibit efficient electron field emission properties such as high field emission current density (80 mA/cm(2)), low turn-on field (1.0 V/μ...
In this study, phenol-formaldehyde (PF) resin has been modified with titanium dioxide nanoparticles (nano-TiO2) at a varying ratio from 0.05 wt.% to 1.5 enhance the thermal properties and combustion performance of resins. The effect nano-TiO2 modification on (chemical or thermal) resins was determined by Fourier transform infrared (FT-IR) analysis (TGA) techniques. addition, laminated veneer lu...
The effectiveness of photocatalytic processes is dictated largely by plasmonic materials with the capability to enhance light absorption as well as the energy conversion efficiency. Herein, we demonstrate how to improve the plasmonic photocatalytic properties of TiO2/Al nano-void arrays by overlapping the localized surface plasmon resonance (LSPR) modes with the TiO2 band gap. The plasmonic TiO...
Background and purpose: Sonocatalytic process as an advanced oxidation process is considered for degradation of pollutants in aqueous solution. The aim of this study was to increase the removal of dye by doping of TiO2 with non-metal element such as nitrogen. Materials and methods: Un-doped and N-doped TiO2 nano-particles with different nitrogen contents were synthesized by a simple sol–gel me...
An estimated 1% or less of nanoparticles (NPs) deposited in the lungs translocate to systemic circulation and enter other organs; however, this estimation may not be accurate given the low sensitivity of existing in vivo NP detection methods. Moreover, the biological effects of such low levels of translocation are unclear. We employed a nano-scale hyperspectral microscope to spatially observe a...
Nanomaterial production is expanding as new industrial and consumer applications are introduced. Nevertheless, the impacts of exposure to these compounds are not fully realized. The present study was designed to determine whether gestational nano-sized titanium dioxide exposure impacts cardiac and metabolic function of developing progeny. Pregnant Sprague-Dawley rats were exposed to nano-aeroso...
To improve the durability performance of recycled aggregate concrete in actual use, this paper uses nano-TiO2-modified coarse to study, through experiments, effects nano-TiO2 on pore distribution after freeze–thaw. The capillary-water-absorption law was used as evaluation index. prepared with different contents nano-TiO2, and changes 24 h capillary water absorption porosity freeze–thaw cycles w...
Önemli bir bileşeni hümik asitler (HA) olan sulardaki doğal ornaik maddeler (DOM) uğradıkları fiziksel, kimyasal ve biyolojik değişimler sonucunda arıtma tesislerinde çeşitli problemlere sebep olmaktadırlar. Konvansiyonel arıtım prosesleri bu bileşiklerin giderimde yetersiz kaldıkları için ileri ile giderimleri hedeflenmektedir. Son yıllarda en dikkat çekici yöntemlerden biri de katalitik ozonl...
The photocatalytic degradation of gaseous toluene was investigated on TiO2 nanoparticles coated on reduced graphene oxide. Reduced graphene oxideTiO2 composite (RGO-TiO2) was synthesized via two step processes. The prepared RGO-TiO2 composite was characterized using SEM, XRD, and UV-visible spectra. A significant increase in light absorption to visible light was observed by RGO-TiO2 compared wi...
