Extensive use of nanoparticles (NPs) in consumer and industrial products has led to concerns about their potential environmental impacts; however, the influences of different NPs (e.g., nZVI (nano zero-valent iron), Ag NPs, Fe2O3 NPs and MgO NPs) on the anaerobic digestion of sludge have not yet been studied in depth. Additionally, a new guideline or the use of different NPs in the anaerobic di...

Magnesium oxide (MgO) thin films were deposited on silicon and glass substrates by the radio frequency (RF) sputtering method. The MgO annealed at 400 ⁰C for 4h. effect of working pressure structure optical properties was investigated. Structural characterization determined using X-ray diffraction (XRD) XRD results showed presence dominant peaks corresponding to (200) (220) lattice planes MgO. ...

In this research, different amounts of nano-MgO were added to normal concrete samples, and the effect these particles on durability samples under freeze thaw conditions was investigated. The compressive tensile strength as well permeability containing nanoparticles measured compared those plain (without nanoparticles). age percentage nanoparticles, water-to-binder ratio are variables current re...

the mixed metal nanocomposite mgo∙al2o3∙zno has been prepared by coprecipitation method. the product was characterized by xrd. the average particle size was found to be 34.89 nm from xrd data. sem and sem-eds were studied for evaluating surface morphology and elemental composition. the ftir spectrum of prepared mixed metal nanocomposites mgo∙al2o3∙zno and mgo∙al2o3∙zno-curcumin were studied. th...

Abstract Nickel based nano-catalysts, supported on bimetallic oxide support (i.e. Ni/Al 2 O 3 -MgO) were prepared by the co-precipitation (one step, Catalyst-A) and followed impregnation (two steps, Catalyst-B) techniques separately. The catalysts then tested for dry reforming of methane (DRM) reaction. effect catalyst synthesis technique their performance has been analysed. -MgO nano-catalyst ...

Molecular beam epitaxy growth of polar MgO(111) and NiO(111) films demonstrates that surface stabilization the is achieved via formation neutral nano-faceted surfaces. First-principles modeling reveals does not proceed layer-by-layer. Instead, Mg or O layers grow up to a critical sub-monolayer coverage, beyond which next layer becomes energetically favorable. This non-layer-by-layer accompanied...

We investigate a possibility to use composite magnetic tunnel junction structures (MTJs) to compose fast memory devices and efficient spin-torque nano-oscillators. In terms of magnetic memory, we study the switching statistics dependence on memory cell geometry by means of systematic micromagnetic simulations. We find that MTJs with a free layer composed of two ellipses with the axes a/2 > b in...

SEM and SEM-EDS were studied for evaluating surface morphology and elemental composition. The FTIR spectrum of prepared mixed metal nanocomposites MgO∙Al2O3</s...

In order to study the effects of recycled aggregate with different particle gradations and contents on mechanical properties cement soil modified by nano-MgO, unconfined compressive strength scanning electron microscope (SEM) tests were carried out. The content was fixed at 15% nano-MgO 1.5%. two ages, three contents, considered. test results show that natural graded (RA), coarse (SRA), fine (T...
