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...

The current study investigates the dissipation kinetics of two imidacloprid (IMI) nanoformulations (entitled: Nano-IMI and Nano-IMI/TiO2) on common bean (Phaseolus vulgaris) seeds under field conditions and compares them with 35% Suspension Concentrate (SC) commercial formulation. To do so, it sprays P. vulgaris plants at 30 and 60 g/ha within green bean stage, sampling them during the 14-day p...

In recent years, the effects of heterogeneous catalysts for the oxidation of organic and inorganic pollutants in industrial wastewaters are spread. Traditionally, these reactions are usually carried out using suspensions of photo-catalysts such as TiO2. A chemical method including TiCl4, Al(NO3)3, ethanol amine, ethyl acetoacetate and aqueous ammonia were used for the fabrication of TiO2-Al2O3 ...

Welding fume is a complex mixture containing ultra-fine particles in the nanometer range. Rather than being in the form of a singular sphere, due to the high particle concentration, welding fume particles agglomerate into long straight chains, branches, or other forms of compact shapes. Understanding the transport and deposition of these nano-agglomerates in human respiratory systems is of grea...
