Mesoporous silica-coated hollow manganese oxide (HMnO@mSiO(2)) nanoparticles were developed as a novel T(1) magnetic resonance imaging (MRI) contrast agent. We hypothesized that the mesoporous structure of the nanoparticle shell enables optimal access of water molecules to the magnetic core, and consequently, an effective longitudinal (R(1)) relaxation enhancement of water protons, which value ...
up to now, lots of materials such as active carbon, iron, manganese, zirconium, and metal oxides have been widely used for removal of dyes from contaminated water. among these, ferrite nanoparticle is an interesting magnetic material due to its moderate saturation magnetization, excellent chemical stability and mechanical hardness. graphene, a new class of 2d carbonaceous material with atom thi...
Zinc oxide (ZnO) is a promising metal oxide semiconductor with various applications, especially in the photocatalytic destruction of environmental pollutants. However, this nanoparticle has some limitations, such as poor dispersion, aggregation, and a wide energy gap. As such, the doping of metal oxide semiconductor has been strongly recommended. Addition of manganese (Mn) has proven effective ...
Present research expresses an experimental investigation on nanoparticle use to enhance Solar still (SS) yield. Manganese Oxide (MNO2) is selected as a material and used in SS. The nanomaterial added with the black chrome paint of SS walls increase weight concentrations (WC) MNO2 have been from 20% 50 see its effect It has observed that heat transfer water temperature enhanced by paint. improve...
Manganese-nickel (Mn-Ni) oxide films were electrodeposited on a graphite sheet in a bath consisting of manganese acetate and nickel chloride, and the structural, morphological, and electrochemical properties of these films were investigated. The electrodeposited Mn-Ni oxide films had porous structures covered with nanofibers. The X-ray diffractometer pattern revealed the presence of separate ma...
Nano-sized particles of manganese oxides have been prepared by a very simple and cheap process using a decomposing aqueous solution of manganese nitrate at 100 °C. Scanning electron microscopy, transmission electron microscopy and X-ray diffraction spectrometry have been used to characterize the phase and the morphology of the manganese oxide. The nano-sized manganese oxide shows efficient cata...
The combustion front is a crucial parameter in determining the efficiency of situ techniques during enhanced oil recovery. Nowadays, catalytic systems are widely believed to be an efficient tool stabilize front. This study aimed investigate synthesis and activity manganese (II) oxide nanoparticles high-temperature oxidation heavy oils. high low-temperature regions were investigated this study. ...
